Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple housing variants are used to compensate for different window curvatures and inclinations, then adaptability to various vehicle types is improved, but device complexity and production costs increase
Solution Approach 1:
The holder is designed with a pivotable carrier that can be adjusted to different angles and positions. The carrier can pivot relative to the holder around a pivot axis, allowing the sensor unit to be oriented at different angles to compensate for various window curvatures and inclinations. This dynamic adjustment capability eliminates the need for multiple fixed housing variants.
Solution Approach 2:
The holder is designed as a universal mounting structure that can accommodate different sensor units and adapt to various vehicle window types through the pivotable carrier mechanism. The fixing device with worm mechanism and worm wheel provides a universal solution for securing the carrier at different angles, making the holder applicable to multiple vehicle types without requiring type-specific housings.
2Adaptability or versatility
If multiple housing variants are used to compensate for different window curvatures and inclinations, then adaptability to various vehicle types is improved, but manufacturing costs increase
Solution Approach 1:
The pivotable carrier with adjustable angles allows a single holder design to serve multiple vehicle types, eliminating the need to manufacture multiple housing variants. This reduces production complexity and costs while maintaining adaptability to different window geometries.
Solution Approach 2:
The universal holder design with pivotable carrier and adjustable fixing positions can be used across different vehicle types, reducing the variety of components that need to be manufactured and stocked, thereby lowering production and inventory costs.
3Reliability
If a self-inhibiting fixing device is used to lock the pivot angle, then reliability of angle fixation is improved, but device complexity increases
Solution Approach 1:
The worm mechanism inherently provides self-inhibition and self-locking properties due to its mechanical design. When force is applied to rotate the worm wheel, it drives the worm and locks the carrier at the desired angle. The reverse motion is prevented by the self-inhibiting nature of the worm gear, providing reliable angle fixation without requiring additional active locking mechanisms or complex control systems.
