Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the number of sensors is increased to improve position detection resolution, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent combines pressure detection and inclination detection functions into a single integrated system. By merging the capabilities of multiple sensors into a coordinated two-sensor system, the invention achieves high-resolution position detection without requiring a large number of separate sensors, thus resolving the contradiction between measurement precision and device complexity
Solution Approach 2:
The invention transitions from one-dimensional pressure-only detection to two-dimensional detection by incorporating inclination direction information. This dimensional enhancement allows the system to achieve higher position detection resolution using only two sensors instead of requiring multiple sensors arranged in a grid, effectively resolving the contradiction between measurement precision and the number of sensors
