Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If current valve install-removal tools are used on TPMS valves, then the valve can be installed/removed, but excessive force is required and damage occurs to the valve, wheel rim, and tool
Solution Approach 1:
The tool incorporates an articulating assembly with multiple degrees of freedom that allows dynamic adjustment of the valve stem orientation during installation and removal. The linkage system enables the valve to articulate and maintain perpendicular alignment with the wheel rim throughout the operation, adapting to forces applied by the user while preventing damaging misalignment.
Solution Approach 2:
The tool changes the operational parameters by maintaining constant perpendicular orientation of the valve stem relative to the wheel rim during installation and removal. This parameter control (orientation angle) prevents excessive radial forces that cause damage, while the articulating mechanism allows the system to adapt to varying axial forces applied by the user.
2Device complexity
If current valve tools allow non-perpendicular valve orientation during installation/removal, then operation is simpler, but the force required increases dramatically
Solution Approach 1:
The articulating assembly provides dynamic orientation control that maintains perpendicular alignment automatically during valve installation and removal. The linkage system absorbs and redistributes forces through its degrees of freedom, preventing force buildup while maintaining the optimal perpendicular orientation without requiring complex user manipulation.
Solution Approach 2:
The articulating assembly acts as an intermediary between the user's applied force and the valve stem orientation. It mediates the force transmission by allowing controlled movement and articulation, maintaining perpendicular alignment while accommodating varying force magnitudes and directions applied by the user during operation.
3Productivity
If excessive force is applied during valve installation/removal, then the valve can be installed/removed, but ergonomics deteriorate and user fatigue increases
Solution Approach 1:
The tool maintains the optimal orientation parameter (perpendicular alignment) throughout the operation, preventing force multiplication that would require excessive user effort. The articulating mechanism allows smooth operation with controlled force application, improving ergonomics while maintaining installation/removal efficiency.
