Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the wheel electronics module is designed with a fixed mounting geometry, then the manufacturing precision is improved, but the adaptability to different wheel rim and valve geometries deteriorates
Solution Approach 1:
The mounting structure incorporates adjustable components including a clamp assembly with movable clamping arms and a positioning mechanism that allows the sensor housing to be mounted at various angles. This dynamic adjustment capability enables the same device to adapt to different wheel rim and valve geometries while maintaining reliable contact with the interior rim well.
Solution Approach 2:
The system allows changing of mounting parameters such as the angle of the sensor housing relative to the valve stem, the position of the clamp assembly along the valve body, and the orientation of mounting wings. These parameter adjustments enable compatibility across diverse wheel and valve configurations without sacrificing mounting precision.
2Reliability
If the sensor housing is designed to contact the interior rim well, then the reliability of pressure monitoring is improved, but the device complexity increases due to the need for precise positioning mechanisms
Solution Approach 1:
The mounting structure is divided into separate functional components: a clamp assembly for securing to the valve, mounting wings for positioning, and an adjustable housing. This segmentation allows each component to perform its specific function independently, simplifying the overall design while ensuring reliable contact with the rim well through the coordinated action of these modular elements.
3Adaptability or versatility
If multiple specialized assemblies are created for different wheel and valve combinations, then the adaptability is improved, but the device complexity and manufacturing costs increase
Solution Approach 1:
The mounting structure is designed as a universal system that can accommodate various wheel rim and valve geometries through adjustable parameters. The clamp assembly can be positioned at different locations, the housing can be oriented at multiple angles, and the mounting wings can be adjusted to fit different configurations. This single universal design replaces the need for multiple specialized assemblies, reducing complexity while maintaining broad compatibility.

AI summary
A tire monitoring system with mounting features on a housing provide for positioning through a wide range of angles. Accordingly, the system can be positioned on an a variety of wheel rim/valve combinations. The tire monitoring apparatus includes two opposed wings provided on the housing to facilitate the range of positioning angles at which the housing can be positioned with respect to a valve base. Each opposed wing has a same exterior surface radius of curvature and the wings are clamped between a base plate and a clamp plate at the desired angle.
