Compact Push-Latch Mechanism Design
Budget: ₹600 – ₹1,500 INR
I’m developing a small product that needs a truly compact push-to-lock / push-to-release latch. Picture something no larger than 1–2 inches overall that can survive both indoor and outdoor use while handling a moderate load. When the user pushes the part in, it must snap firmly into place with a clear tactile “click”; a second light push should free it just as confidently, ready for countless cycles of the same action.
Material-wise I’m leaning toward injection-mouldable plastics such as TPU or a similar resilient polymer, so any geometry you create has to respect typical draft angles, wall thicknesses, and shrinkage. I’d like to keep the component count low—ideally no elaborate multi-stage springs—yet the mechanism should still feel solid, hold fast under vibration, and release without sticking.
Because space is at a premium, please treat every cubic millimetre as valuable and design accordingly. A durable, low-profile construction that can be printed for early prototyping and then tooled for mass production is exactly what I need.
Deliverables:
• 3D CAD model (native file + STEP/IGES)
• Brief mechanism explanation showing the lock/unlock sequence and key contact points
• Basic dimensions, tolerances, and any critical material or finish notes
If you’re confident you can package reliable motion into a tiny footprint without over-engineering it, I’m eager to see your approach and iterate quickly toward a production-ready solution.
