Problem
Conventional housing assembly methods, such as screwing and ultrasonic welding, are inefficient and costly, with a high risk of detachment under external forces due to the need for additional tools and the uncertainty of connecting quality.
Innovation Solution
A housing structure design featuring a connector with bumps and connect hooks that engage to securely connect two housings without the need for additional fixing methods, allowing for easy assembly and maintaining the connection under external forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If screws or connecting structures are used to connect two housings, then the housings can be assembled together, but additional tools are needed and the connecting quality cannot be easily controlled
Solution Approach 1:
The housing connection structure enables self-service assembly through the elastic connect hooks that automatically engage with the bumps on the other housing. The elastic deformation of the connect hooks during assembly allows for tool-free connection while maintaining secure fastening, eliminating the need for screwdrivers or other additional tools.
Solution Approach 2:
The connect hooks are designed with elastic properties that allow them to dynamically deform during the assembly process. This elasticity enables the hooks to flex outward during assembly and then spring back to engage securely with the bumps, providing a dynamic assembly mechanism that simplifies the connection process.
2Strength
If screws are used to connect housings, then the housings can be fixed together, but production speed decreases and production cost increases
Solution Approach 1:
The elastic connect hooks automatically engage with the bumps through their own elastic deformation, eliminating the need for manual screw tightening operations. This self-service mechanism significantly accelerates the assembly process while maintaining adequate connection strength for the application.
Solution Approach 2:
The invention extracts the fastening function from complex screw connections and implements it through simple elastic hooks that engage with bumps. This extraction of the essential fastening function removes unnecessary complexity and time-consuming operations while retaining the core requirement of securing the housings together.
3Ease of manufacture
If conventional connecting structures with recesses and hooks are used, then two housings can be connected, but the connection is easy to detach under opposite forces
Solution Approach 1:
The connect hooks are designed with asymmetric geometry where the hook opening faces a specific direction. This asymmetric design, combined with the elastic properties, creates a connection that is easy to assemble in the correct orientation but resistant to detachment under opposite forces, as the elastic hooks engage securely with the bumps in the intended assembly direction.
Solution Approach 2:
The elastic connect hooks provide dynamic engagement with the bumps, creating a stable connection that can withstand external forces. The elasticity allows the hooks to flex and conform to the bumps, maintaining secure engagement under various loading conditions while preventing easy detachment.
4Strength
If ultrasonic welding is used to connect housings, then the housings can be firmly fixed, but the process has risk of failure and decreased production yield
Solution Approach 1:
The invention replaces the ultrasonic welding process with a mechanical connection system consisting of elastic hooks and bumps. This substitution eliminates the thermal and process complexities of ultrasonic welding, providing a more reliable and fail-safe connection method that maintains firm fixing strength without the production yield issues associated with welding failures.
