Curious to know more about you experience working in medical devices manufacturing - learning and growth opportunities, level of challenge, work life balance, fun factor, etc. Please share your experiences.
You probably recognize me from my previous post. I had a quick chat with my current boss and he said I'll be 'taking a step back' by leaving my role in quality, and going into design.
He also expressed that they won't be giving him someone to replace me. Also that he had plans for my growth, and the new department doesn't have a lot of growth opportunities. But he never expressed this in our meetings and never elaborated on this at any given point.
I don't know if this is true but I've made up my mind and not looking back. Feel free to share what you think about this.
I worked on a product that my company filed for a patent on. I wasn’t familiar with the patent process, so I didn’t think anything of it when they asked for drawings to file, but I’ve now learned that another employee (above my station) is listed as the inventor, and I was left off.
To be clear, I didn’t invent the specific mechanism, but I did the work to make it manufacturable for mass production. The form that it exists in the patent drawings is my work.
From my brief research it looks like there can be multiple inventors listed, so I’m at a loss for why they would leave me off the patent.
I want to have a discussion with management about this, but I don’t want to go into it without knowing what my options are. Can I be added after the fact? Is it common for companies to minimize the amount of inventors listed on a patent?
I’ll take some of the blame here as I did zero research into how patents are structured, I just assumed that it belonged to the company and didn’t realize specific employees would be named on it.
I am a graduating senior, and I unfortunately can’t find a job because I didn’t successfully land an internship. People say you need internships to stand out for full time jobs, but how were you supposed to stand out for internships?
Hello there everyone hope you are all having a good day. I'm here to ask a simple question regarding studies and extracurricular activities, personal projects. I am an aspiring mechanical engineering student and later this year I'll start with my first year of college. One thing always bothered me in school was how just theory ridden everything was (even though I really liked the chapters regarding semiconductors, Circuit, pulleys, Dynamics in general), I always wished it to be bit more than that. I used to see other people some of them of my age creating cool stuff and it makes me very envious of them and I ended up learning circuits on breadboards, CAD software, C++ and some python which was good but then I always find it hard to manage my ongoing studies and failed some test, it felt terrible.
In the end I decided to not let that happen again in college, So please provide some insight.
I want create something cool that's it and enjoy the process too (and in the end get paid to do so lol).
Hello,
I am working on a project at uni, and i need a lightweight (as light as possible) way to translate linear motion thats adjustable with an electronic gyro.
The size parameters of the construction is around 10cm broad base (max width) and a 7 cm horisontal shaft with a 15cm vertical shaft. both shafts need to be adjustable electronically and lightweight.
The current idea is to make a contraption with an electromagnet to change its push/pull force. Is this feasable?
I’m struggling with this specific system: I have two different branches, each with it’s own fluid properties and centrifugal pump. The two lines mix together resulting in a new fluid with different properties. How can I calculate the total system curve ?
I have a coworker who wants to do a bonded repair doubler on an aircraft in an area where it would need to pick up existing rivets. The only information I was able to find on mixing adhesive and rivets is in Chapter 9 of Nieu, which provides two (seemingly) contradicting statements. In one sentence it states that the bonded area will carry most of the load, and in another it says to provide sufficient fasteners to carry all of the static ultimate loads as no load is carried by the bonding.
My worry is that by bonding the repair, the adjacent rivets will end up picking up all of the loading from the repair until they start to fail. Could someone point me in the right direction here? Thanks in advance.
Hey guys what are your views of the company Emerson? Anything u have abt them pls comment or more specifically if you know anything bt their service engineer for marine smart propulsion position…
Appreciate any help or comments!
The question may be subjective.
In May 2023, I completed my Bachelor's in Mechanical Engineering with a CGPA of 3.21 out of 4. I had a very rough start during the first two semesters, with around 2.2 in each, but I managed to bounce back and reached an overall CGPA of 3.21. Up to now, I have completed only one internship and have 5 months of experience as a technical writer. I have a total of 4 academic projects, along with some extracurricular activities with various organizations.
As I heard that many universities are waiving the GRE, I didn't take the test, although my English proficiency is not very high, so I don't believe I would score above 310. My IELTS score is 6.5 overall (not less than 6.5 in each band). Additionally, I won't be able to afford the fees, even with less than a 50% scholarship.
Here are my questions:
P.S. I am also considering Germany, but I am unable to find the course I want to pursue, and I do not have a German language certificate, not even A1 (although I am aware that some programs require this).
Where I'm from, we often rely on low-cost Chinese diesel engines across various sectors like agriculture and water transport. These engines tend to be inefficient and endure heavy usage over decades, further degrading their performance. I was looking to start a free and open source project in collaboration with my university to enhance the efficiency and speed of these engines, potentially leveraging microcontrollers. The free and open source aspect would mean any electrician around the country would be able to make them from scratch just from our guide. My question, although a little broad, was how computers are utilized to optimize engines and their associated systems like transmission, gearboxes, and fuel systems. Any recommended external resources would be greatly appreciated as well, just trying to get some info. Thanks a lot.
Where should I get my MSc. from?
I’m planning to get an MSc. In either Ireland or the UK. I’m not a resident of either countries so I can’t say I have any idea of how the market looks like in either place. My degree is in Mechanical Engineering.
In the Uk I’d be studying engineering design at either Plymouth or Coventry. In Ireland I’ve been strongly leaning towards UCC to study manufacturing, process & automation systems.
Can anyone comment on employability post study, salary ranges, career progression and if the schools I’ve chosen will be worth it. I’m dead set on doing a masters I just don’t know where. Thank you in advance.
Some additional info: I have worked in the building services industry (Mechanical works design and site work ) I have a solid understanding of both solidworks and revit MEP
As an international student, I am currently looking for a master's degree in the HVAC field in the United States or Europe.
Unfortunately, I could not find any master's degrees that explicitly stated MS or MEng in HVAC. Why is this the case?
What other degrees are possible in HVAC, energy, thermal systems, and so?
Sup Engineers! I'm a mechanical engineering student and I'm looking for a laptop that could carry all the workload for my entire colleges years. What would be a good specs to look for?
I am stuck at a fork in the road of my career path.
I am stuck between pursuing a career in project management, which I do enjoy but it's not very technical and I enjoy "building" things. However, I feel that career wise project management has a higher ceiling in terms of potential positions, pay and challenges.
On the other hand, mechanical engineering design (mainly automation of mechanical machinery and design of mechanical mechanisms) is more fun and exciting as I get to see my designs come to life and work in the way i intended.
I am still quite young, 26 years old and I'm not American btw. But I'd like to make a decision regarding these two pathways and pursue accreditation that will enhance my skills. In your guys experience, what is a better pathway to go down?
Hi guys!
I’m about to go to collage to get into mechanical engineering. It’s going to be a part time bachelor’s and I will need to find a job in the field.
My background is 3D modelling and animation in the creative sector, the school that I applied to told me I should create something that would “impress” my potential employer.
What would be a good piece to create? And do you guys have any other tips?
Cheers!
For my Dynamics class we have to make some mechanism featuring rotational to linear motion and create a model that we can fully animate to show its motion. However, I’ve only ever done basic CAD on Onshape and our model is due in two weeks. I’m hoping people have some advice on the most beginner friendly software to use for this?
I’ll first start by saying i’m definitely too young to be having these thoughts. I haven’t even explored all what’s in store in terms of the industry. However i was thinking about switching gears and explore getting a masters degree in business. My idea is to focus on the business side of engineering rather project side engineering. I’m thinking it may be more spontaneous and chaotic (which i like) and still be just as, if not more, lucrative. Again this is just a thought, lmk your opinions
I got a minors in CS during my first two years of ME. It seemed like most of my ME peers really hated coding, but I loved it.
I want to work in robotics, automation, or aerospace. Would getting a Bachelor's in CS from like WGU over a few summers be worth it? I already have my Minors so I'm halfway done, but would a bachelor's give me anything that a Minors wouldn't in terms of getting a job out of college?
Hey, I saw a smart gym bench press system that I'd like to replicate. The video can be found here: https://youtu.be/eG3WdCOGr-Y?si=1S0reZc5TAEP35UT. This system utilizes two linear actuators to push the barbell. Assuming the system is highly durable and can handle barbells around 1000 lbs, each actuator should be capable of supporting 500 lbs. This requires each actuator to exert 2000 - 3000 Newtons to counteract gravity. The movement range is from the ground to 1.8 meters. I am not a mechanical engineer, but a software engineer. I am wondering what kind of linear actuator is best for this job. I'm thinking they might be using a belt-driven linear actuator, but I'm not entirely sure. Thanks for any insights!
It's so frustrating trying to figure out what entry-level jobs should pay. Some sources say $65,000 is normal, others insist on $75,000-$85,000. Plus, it's hard to compare when benefits aren't always factored in when people mention from where they started at.
Like even in my friend group there’s been a massive range of starting salaries, from 65-95k with no experience.
Looking at Reddit also doesn’t help either lol, there’s always two extreme ends. Some saying you only make substantial pay increases after job hopping.
I’m an exhausted senior, I’ve had two internships in defense, a decent GPA and wasn’t able to get interviews. Now I’m looking at going into construction/field engineering and that has muddy results.
What has your experience been at entry level? Any recruiters here have any advice?
I am a sophomore right now who is interested in getting into HVAC. I will graduate with a bachelors of MechE and I plan on getting an ‘energy engineering’ minor that is focused specifically on the design of efficient HVAC systems.
I’m just curious if anyone who has broken into the HVAC design world has any advice or information they wish they had at my age?
What are the best types of jobs for this specialty regarding pay and work life balance?
Is work in this field easy to come by? Do you feel like your job and the field as a whole is a pretty solid/ safe field to go into?
What should I really focus on now in my schooling whether that be certain classes or organizations to best help my future career?
Any responses help thank you so much I really appreciate it!
I just recently started my first engineering job out of college. I generally work 6:30-3:30, but will of course stay over to work on any urgent problems. The two other engineers in my department generally work 6:00-4:00. I am conflicted about this, as sometimes I feel guilty about working less than them, but at the same time I feel like 9 hours a day is plenty. I also make sure that any work that is urgent is always done and nobody needs help with anything before I leave.
It’s also worth noting that the general culture where I work is leaving when it’s time to leave (as long as your important work is done) and my department has a reputation for working more than required. My fellow process engineers haven’t given me any grief on the issue, but I still sometimes wonder if they think I’m not committed enough. I’d appreciate any thoughts on this, especially from those with managerial experience. Thank you.
I'm still a university student, but notice that I am very much interested in finance and business related topics. I also could not see myself wanting to work on CAD or projects all day.
Is there any ways to accelerate my progress to get these types of roles? Is an MBA standard, or do people sort of work up a ladder within a company?
What common readily available materials have high COF on plywood or concrete? Is there a specific surface pattern that has a high grip?
As a mechanical engineer what softwares should I have a great grip on?!?
I’m designing a quadruped leg and have come up with something that looks like this. Obviously the drawing looks ridiculous but I want to highlight the potential issue. The goal is to have the shank vertically aligned with the upper leg so it must go on a shaft in the middle between a sort of fork in the upper leg like shown. Now I’m debating between using a fixed or rotating shaft. By my own intuition, since the pulley for the timing belt is not horizontally centered on the shank, if I use a fix shafted the clearance fit required by the pulley/shank + the off center force from the belt will cause the whole shank to deflect. If I use a rotating shaft (attach the shaft to the pulley) then I can use a tighter fit and the set screw or other shaft locking mechanism will prevent the shank from deflection. Is this sound? Are there other factors I’m not considering?
All i see are posts from software subreddits where they brag about how much they earn and compared to how less they started at, for example they start at 80-100k and and earn upto 250-300k even with 5-6 years of experience. So my question is whats the salary growth like in Mechanical Engineering jobs as you gain experience? Can you really switch companies as often like people in tech for a better paying job?
