Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal threads are used in the tire connection valve device, then strength and dimensional stability are improved, but manufacturing cost and complexity increase
Solution Approach 1:
The patent employs a plastic thread instead of metal, accepting that the thread may be damaged during use but prioritizing cost-effectiveness and ease of manufacture. The plastic thread is sufficient for the intended application lifecycle, and replacement is simpler and cheaper than metal thread replacement.
Solution Approach 2:
The patent substitutes metal mechanical components with plastic alternatives. The plastic thread provides the necessary mechanical function at lower cost and with easier manufacturing processes, eliminating the need for expensive metal machining while maintaining adequate strength for the application.
2Volume of moving object
If the tire connection valve device is made compact, then space requirements are reduced, but the arrangement of functional elements becomes more difficult
Solution Approach 1:
The patent combines multiple functional elements into a single integrated plastic base body. The thread, release valve, and closing element are all formed as one piece through injection molding, eliminating the need for separate components and complex assembly. This merging approach achieves compactness while simplifying the overall device structure.
Solution Approach 2:
The plastic base body serves multiple functions simultaneously: it provides the threaded connection interface, houses the release valve mechanism, and incorporates the closing element. This multi-functionality in a single component reduces the number of parts needed and simplifies the compact design.
3Ease of operation
If a release valve is integrated into the tire connection valve device, then air pressure regulation is improved, but device complexity increases
Solution Approach 1:
The release valve is integrated directly into the plastic base body as a molded-in feature rather than a separate component. The valve element, spring, and housing are all formed as one piece through injection molding, providing air pressure regulation functionality while minimizing the number of discrete parts and assembly steps.
Solution Approach 2:
The release valve is designed to operate automatically based on internal pressure conditions. The spring-loaded valve element opens when pressure exceeds a certain threshold, providing self-regulating air pressure control without requiring external control mechanisms or complex electronics.
