Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If two wheel speed sensors are installed for each wheel to improve detection accuracy and reliability, then measurement precision and reliability are improved, but device complexity and space requirements increase
Solution Approach 1:
The patent combines two separate wheel speed sensors into a single integrated sensor unit with a common housing. The housing contains both sensors and provides a unified mounting structure that connects to the chassis, merging what would traditionally be two separate assemblies into one compact device. This reduces overall complexity while maintaining dual-sensor functionality for improved detection accuracy and redundancy.
2Reliability
If two wheel speed sensors are installed for each wheel to improve detection accuracy and reliability, then measurement precision and reliability are improved, but the space required for installation increases
Solution Approach 1:
The patent employs a nested structure where one sensor is positioned inside the housing of another sensor, or both sensors are arranged in a compact nested configuration within a single housing. This nesting approach allows two sensors to occupy significantly less space than two separate sensors would require, while still providing the redundancy needed for improved reliability.
3Stability of the object's composition
If two wheel speed sensors are arranged side by side, then stability and alignment are improved, but assembly complexity increases
Solution Approach 1:
The patent segments the sensor assembly into modular components: a housing that contains both sensors, individual sensor modules that can be independently installed, and a unified mounting structure. This segmentation allows for pre-assembly and testing of individual components, then straightforward integration into the final assembly, reducing overall assembly complexity while maintaining stable side-by-side sensor alignment.
