https://lnkd.in/gZuk4zuW i would say this is a holy grail of finding for young designer who wish to learn on design a good machine. from selection of motor, to linear guide calculation, to spring calculation, all is here.

It's fun and satisfying to create something new, but there's SO much one can learn by studying the designs of others! As a mechanical engineer, ⚙ 🤓 I really enjoy building a LEGO TECHNIC set with motors, gears, linkages, etc. There's something therapeutic about following the printed* instructions, without knowing in advance how the mechanisms work... and discovering new building techniques while assembling the model. 🔩 🔧 As a kid I used to disassemble non-LEGO products** around the house, to see how they worked... 😅 ...then I'd eventually put them back together. More often than not, they were still functional. The advantage of a great LEGO set it that it's meant to be disassembled - and next, with those parts, you can build whatever you want! What kinds of things have you reverse-engineered recently... or as a kid, if you can remember? #LEGO #engineering #AFBmadethis * The interactive digital instructions on my iPad are pretty cool, too! ** our vacuum cleaner, my new ATARI 2600, etc.

A power transmission device, commonly known as a "transmission," is a meticulously engineered component in mechanical engineering. Its primary function is to transfer or translate an input source of torque or rotation into multiple output sources of torque or rotation, as required by the user. These devices come in various shapes and configurations, but the underlying concept remains consistent. This example of a linear conic design illustrates how shifting gears, either manually or automatically, changes the output rotation accordingly.

 "From Idea to Reality: The Mechanical Design Workflow" "At Braint Design Hub, we follow a structured mechanical design workflow that ensures every machine we create is reliable and efficient. Here's a quick look at the main stages: *Conceptual Sketching: Where ideas begin. *3D CAD Modeling: Turning concepts into detailed digital models. *Simulation & Analysis: Testing for stress, motion, and performance. *Prototyping: Creating and testing a physical model. *Production: Final adjustments and manufacturing. This approach helps us develop high-performance machinery, like shrink wrapping and track and trace systems, with precision and confidence. Stay connected as we explore each phase in more detail in upcoming posts!"

How LEGO and a Vacuum Create the Roar of an Engine 🚗💡 🎼 A magnificent creation made from LEGO pieces and powered by a vacuum cleaner produces the sound of a revving engine. It showcases childhood creativity and mechanical engineering principles brought to life. 🌀 This build uses air displacement and controlled release to simulate the combustion process of a 4-cylinder engine. Each cylinder is made of LEGO pieces and breathes airflow to create synchronized movement and sound. 🛠️ The LEGO build includes pistons and valves that open and close at precise intervals, much like real engines. The setup, powered by the vacuum's airflow, creates movements and sounds similar to an actual engine, exploring concepts like air pressure and piston mechanics. 📚The LEGO vacuum engine is an exciting educational tool that showcases mechanical engineering and acoustics in a hands-on manner. It proves that everyday items can unlock the mysteries of how things work, making engineering principles more accessible and entertaining. 💳Content Credit: hightorquelego (TT) #LEGOEngineering #MechanicalEngineering #DIYProjects #Innovation #CreativeEngineering #STEMEducation #Acoustics #EngineeringPrinciples #VacuumPower #EngineSounds #EducationalToys #EngineeringForKids #PistonEngine #Automotive #Engineering #Engine #V4 #V6 #V8 #V10 #V12 #Sound #CarEngine

When somebody asks me what I do as a Mechanical Engineer, I always have a hard time narrowing it down to just one thing. I remember doing an interview at Apple, and the hiring manager explained to me what mechanical engineering is to them using a simple chair as an example. It’s amazing how much goes into something that seems so simple! Designing a chair involves a multitude of considerations: - Tolerance Stack-Up: Ensuring every part fits together perfectly, accounting for slight variations in manufacturing. - Weight Capacity: Making sure the chair can support various weights without compromising its integrity. - Safety: Ensuring the chair doesn't tip over easily and can withstand everyday use. - Comfortability: Designing the chair to be ergonomic, providing adequate support for the user. - Cost: Balancing material and manufacturing costs to create an affordable product without sacrificing quality. - Material Selection: Choosing the right materials that provide the necessary strength, durability, and aesthetics. This involves understanding the mechanical properties and behavior of various materials under different conditions. - Manufacturability: Designing the chair in a way that it can be easily and efficiently manufactured. This includes considering the capabilities and limitations of different manufacturing processes. - Aesthetics: Ensuring the chair looks appealing and fits within the intended design style or brand identity. - Sustainability: Selecting materials and processes that are environmentally friendly and considering the product’s lifecycle, from production to disposal. - User Experience: Testing prototypes with real users to gather feedback and make necessary adjustments to improve the overall experience. Every aspect of mechanical engineering requires meticulous planning, testing, and iteration. It’s a process that involves a deep understanding of materials, manufacturing techniques, and user needs. From initial sketches and CAD models to prototyping and final production, each step is critical to the success of the final product. Mechanical engineering, in essence, is about being able to critically think and learn from every experience. No engineer knows everything, but through continuous learning and adaptation, we strive to make each product the best it can be. Does anyone else find it difficult to explain their role in a single sentence? #MechanicalEngineering #Engineering #ProductDesign #Manufacturing #MaterialScience #Sustainability #UserExperience #Innovation #EngineeringLife #DesignEngineering

Design in action! ‣ In this image we see the mechanical design coming to life: a physical component perfectly replicated in a 3D CAD model. Precision and attention to detail are the soul of modern engineering. Or what do you say? This is the balance between creativity and technology. When design materializes, the future becomes reality. My focus has changed radically for a few months now. But I'm starting the journey in 2025.

What! Creative brainstorm sketching is the best part of being a Mechanical Engineer.

Pushing the boundaries of what's possible in assembly design— we have all studied about two stroke or four stroke engine cycle during our engineering study. 1. The purpose of designing this was to improve my kinematics and how can I design the parts in a fast and improved way. 2. Tool used: Catia V5. 3. challenges I faced during this: 1. designing the parts was easy. 2. when we put all the parts together in assembly, and give constraint to our assembly and try to simulate our product. It becomes difficult. 3. While designing any part or product we always use engineering term DFM OR DFA. DFA (Design for assembly): It means products are designed with ease of assembly in mind. So I created sub assemblies of some parts and then assembled with the main part, which helped me in understanding how actually the parts will function or operate. Here is the video of the kinematics engine cycle. You can see I have created the subassemblies. Enjoy .......!!! :)
