Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a dedicated fixture is used to hold door hinges during installation, then the door alignment can be achieved, but substantial labor and time are required for adjusting hinge positions, necessitating production stoppages
Solution Approach 1:
The patent applies dynamics by replacing the static dedicated fixture with a robotic system capable of real-time adjustment. The robot can dynamically reposition the door hinge during the assembly process based on measured alignment requirements, eliminating the need for production stoppages and manual shim installations while maintaining precise door alignment.
2Manufacturing precision
If mechanical shims are installed to adjust door hinge position, then door fit quality can be improved, but the process requires production stoppages and substantial labor
Solution Approach 1:
The patent replaces the mechanical shim installation process with an automated robotic system. Instead of manually installing physical shims to adjust hinge position, the robot directly repositions the door hinge using controlled motion, eliminating the time-consuming shim installation process while achieving the same door fit quality improvement.
Solution Approach 2:
The system performs preliminary measurement of door alignment requirements and calculates the necessary hinge position adjustments before actual installation. This allows the robotic system to pre-determine the exact positioning needed, eliminating the need for iterative shim installation and adjustment during production.
3Manufacturing precision
If a dedicated fixture individually adapted to a single vehicle model is used, then accurate hinge positioning can be achieved, but the system lacks flexibility for different vehicle models
Solution Approach 1:
The patent implements universality by designing a robotic system that can accommodate multiple vehicle models through software programming rather than requiring dedicated physical fixtures for each model. The robot can be reconfigured via control system parameters to work with different vehicle types, maintaining precise hinge positioning accuracy while providing flexibility across multiple vehicle platforms.
