Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If additional positioning technologies are used to recognize the position of moving bodies in spaces with many stationary structures, then the positioning accuracy is improved, but the system cost and complexity increase
Solution Approach 1:
The patent introduces reflective plates as intermediary objects attached to stationary structures. These plates serve as mediators between the optical device on the moving body and the stationary structures, enabling position recognition through reflected light patterns without requiring complex positioning systems. The reflective plates convert the complex environment into a recognizable optical pattern that the analysis unit can process to determine position and orientation.
2Measurement precision
If additional positioning technologies are deployed to achieve accurate position recognition, then the measurement precision is improved, but the manufacturing cost increases
Solution Approach 1:
The patent employs reflective plates as simple, inexpensive objects that can be easily manufactured and deployed on stationary structures. These plates are far cheaper than traditional positioning technologies such as RFID tags, barcodes, or complex optical markers. The reflective plates achieve the same positioning function at a fraction of the cost, making the system economically viable for widespread deployment.
3Device complexity
If traditional positioning methods are used in environments with many similarly arranged stationary structures, then the system is simple, but the position recognition becomes difficult due to pattern repetition
Solution Approach 1:
The patent applies local quality by analyzing the specific distribution pattern of reflected light from reflective plates at each local position. Even though stationary structures are arranged in the same pattern throughout the space, the unique combination and spatial distribution of reflected light signals at each location creates a distinctive optical fingerprint. The analysis unit processes these local light distribution patterns to determine the precise position and orientation of the moving body, overcoming the challenge of repetitive structures.
