Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If pneumatic riveting tools are used, then riveting efficiency is improved, but device complexity and cost increase due to compressed air source requirements
Solution Approach 1:
The patent replaces the pneumatic system with a mechanical hand-operated turning mechanism. The user manually rotates the riveting tool holder, which drives the riveting tool through mechanical transmission, eliminating the need for compressed air sources while maintaining riveting functionality.
Solution Approach 2:
The riveting tool holder is designed to be adaptable to general power output devices, allowing it to function with multiple power sources including manual operation, electric motors, and pneumatic systems. This universal design reduces dependency on specialized pneumatic infrastructure.
2Adaptability or versatility
If integral electric riveting tools are developed, then portability and power source accessibility are improved, but device complexity and unit price increase
Solution Approach 1:
The riveting system is divided into separate components: a riveting tool holder that can be detached and attached to different power sources, and the riveting tool itself. This segmentation allows the same riveting tool to be used with multiple power sources without requiring a completely integrated complex design.
Solution Approach 2:
The riveting tool holder acts as an intermediary device between the power source and the riveting tool. It receives rotational motion from various power sources and transmits it to the riveting tool, simplifying the overall system architecture while maintaining versatility.
3Adaptability or versatility
If screw pair conversion is performed during riveting, then adaptability to different power sources is improved, but device complexity increases due to additional mechanisms
Solution Approach 1:
The screw pair conversion mechanism is merged into the riveting tool holder itself rather than being a separate component. The threaded structure is integrated with the holder's body, reducing the number of parts while maintaining the screw pair conversion functionality that enables adaptability to different power sources.
