Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If signal lines are routed and sorted in an irregular manner to connect force sensors to the LCD panel, then the touch panel can be assembled using conventional methods, but the sense signals are affected by noise with distinct degrees resulting in non-uniformity in electricity and decreased touch precision
Solution Approach 1:
The patent merges multiple signal lines into a single integrated cable that connects all force sensors to the LCD panel. This integrated cable is routed uniformly through the module, eliminating the irregular routing of multiple distinct signal lines. The integration ensures that all sense signals are transmitted through a unified pathway, reducing noise interference variations and improving signal uniformity across all touch sensors.
2Measurement precision
If force sensors and LCD panel are integrated in a module to improve touch panel functionality, then the touch precision is improved, but the assembly and test become inconvenient and maintenance requires disassembling almost everything
Solution Approach 1:
The patent segments the touch panel module into distinct functional components: the force sensor array, the integrated cable, the LCD panel, and the surrounding frame. The integrated cable is designed as a separate, accessible component that can be connected or disconnected without disassembling the entire module. This segmentation allows for convenient assembly, testing, and maintenance while preserving the integrated functionality needed for accurate touch detection.
3Ease of manufacture
If multiple distinct signal lines are used to transfer sense signals from force sensors to the LCD panel, then each sensor can be connected individually, but the assembly and test become inconvenient and time-consuming
Solution Approach 1:
The patent combines multiple individual signal lines into a single integrated cable that carries all sense signals from the force sensors to the LCD panel. This integration reduces the number of separate connections needed during assembly, simplifying the manufacturing process. The integrated cable is designed to interface with both the sensor array and the LCD panel through unified connection points, eliminating the need to handle and connect multiple distinct signal lines separately.
