Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If hot riveting process is used to connect bearing plate and actuating element, then connection strength is improved, but manufacturing time increases and process monitoring becomes difficult
Solution Approach 1:
The patent replaces the thermal hot riveting process with a mechanical snap connection system. The bearing element features a snap connection element that mechanically engages with the bearing plate through elastic deformation, eliminating the need for thermal heating and melting processes. This mechanical substitution reduces manufacturing time while maintaining connection strength through the elastic retention force of the bearing element.
Solution Approach 2:
The patent changes the connection parameter from thermal (hot riveting temperature) to mechanical (elastic deformation force). The bearing element is designed with specific elastic properties that allow it to deform during insertion and retain the connection through its elastic recovery force, fundamentally changing the physical parameter used to achieve and maintain the connection.
2Reliability
If hot riveting process is used to connect bearing plate and actuating element, then connection durability is improved, but process monitoring difficulty increases
Solution Approach 1:
The patent replaces the difficult-to-monitor thermal hot riveting process with a mechanical snap connection that can be easily detected and verified. The snap connection element's engagement with the bearing plate creates a distinct mechanical state that is simple to monitor, eliminating the complexity of monitoring thermal processes and melting behavior.
3Reliability
If hot riveting process is used, then connection reliability is improved, but material deformation risk increases
Solution Approach 1:
The patent substitutes the thermal hot riveting process with a mechanical snap connection that avoids thermal influence on the bearing plate and actuating element. The bearing element uses elastic deformation rather than thermal melting, eliminating the harmful thermal effects that cause material deformation while maintaining connection reliability through the elastic retention mechanism.
