Premium Dog Collar Lock Mechanism Design
Budget: $10 – $30 USD
Hello,
I am looking for a serious mechanical design engineer / CAD freelancer to take an existing premium dog collar locking mechanism concept and turn it into a fully validated, production-ready design.
I already have:
* STL files
* CAD files
* Exploded views
* Animations
* Videos showing the concept and mechanism
The design already exists, but I need an experienced engineer who can independently review everything from scratch and verify that it will actually work in real life.
I specifically need a full engineering review of every critical part of the mechanism, including:
* The push button.
* The main locking pin.
* The yellow sliding/locking component.
* The safety lock functionality.
* The interaction between all moving parts.
* Spring selection and spring forces.
* Travel limits and mechanical stops.
* Locking and unlocking sequence.
* Friction, wear, and long-term reliability.
* Possible jamming scenarios.
* Accidental release prevention.
* Assembly method and manufacturability.
What I need:
* Analyze the complete mechanism and explain it clearly.
* Verify that the locking sequence works correctly.
* Verify that the unlocking sequence works correctly.
* Verify that the yellow component behaves correctly in all states.
* Verify that the push button cannot accidentally bypass or skip states.
* Verify that all dimensions and tolerances are correct.
* Correct any engineering issues.
* Improve the design if necessary while keeping it compact, lightweight, and premium.
* Make it look like a high-end product, not a simple plastic box.
* Keep the overall dimensions as small as possible.
* Optimize it for real manufacturing.
Most importantly:
I do not want only CAD work.
I need someone who can physically prove that the mechanism works.
This means:
* Preparing a prototype-ready design.
* Reviewing and optimizing all dimensions.
* Selecting the correct springs and components.
* 3D printing the parts.
* Assembling the mechanism.
* Testing it physically.
* Recording videos showing the complete assembly and testing process.
* Demonstrating repeated lock/unlock cycles.
* Demonstrating that the mechanism does not jam.
* Demonstrating that the safety lock functions correctly.
* Explaining how every moving component behaves during operation.
My goal is to receive a complete, tested, validated, and production-ready mechanism with evidence that it actually works in the real world, not only inside CAD software.
My budget is limited, so I am looking for someone practical, honest, experienced, and confident enough to test and prove the design before final delivery.
Please tell me:
1. Your experience with mechanical locking mechanisms.
2. Whether you can 3D print, assemble, and physically test the design.
3. Whether you can provide video proof of testing.
4. What files you need from me.
5. Your estimated cost and timeline.
Thank you.
