Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If position-emitting tags or radio signals are used to recognize moving bodies, then position recognition capability is improved, but system cost increases and electronic circuit interference occurs
Solution Approach 1:
The patent replaces electronic position-emitting tags and radio signal systems with an optical system consisting of reflective plates and light radiation/reception devices. This substitution eliminates the need for complex electronic circuits while achieving position recognition through optical reflection principles, thereby reducing system cost and avoiding electronic interference.
Solution Approach 2:
The patent introduces reflective plates as intermediary objects that passively reflect light to enable position detection. Instead of using active electronic tags that emit signals, the reflective plates serve as simple optical mediators that work with the light radiation and reception devices to achieve position recognition without requiring power sources or complex electronics.
2Measurement precision
If complex recognition systems are deployed to accurately identify moving bodies among stationary structures, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The patent divides the recognition system into simple, modular components: reflective plates attached to moving bodies, light radiation devices positioned at strategic locations, and light reception devices for detection. This segmentation allows each component to perform a single, well-defined function, making the overall system easier to operate and maintain while achieving accurate position recognition through the coordinated work of these simple elements.
