Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a filter with a special pattern is exchanged based on the captured object, then measurement precision is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent replaces the mechanical filter exchange system with a liquid crystal display panel that can dynamically change encoding patterns electronically. The LCD panel displays different encoding patterns by controlling liquid crystal pixel states, eliminating the need for physical filter exchange mechanisms while maintaining distance measurement precision for various objects.
Solution Approach 2:
The patent implements dynamic encoding pattern switching by controlling the liquid crystal display panel to display different patterns based on the captured object. This allows the system to adapt to different measurement scenarios in real-time without mechanical intervention, improving both measurement precision and operational simplicity.
