Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If traditional position location systems are used for robots in performance arenas, then the systems can provide basic positioning capability, but they lack speed, simplicity, computational efficiency, and versatility
Solution Approach 1:
The performance arena perimeter is segmented into discrete position indicators with unique patterns, allowing the robot to determine its location by recognizing specific segments rather than calculating position from continuous data, thereby increasing positioning speed while maintaining system simplicity
Solution Approach 2:
The patent replaces complex mechanical or computational positioning systems with an optical recognition system using image sensors to detect coded patterns, eliminating the need for complex calculations and improving both speed and computational efficiency
2Measurement precision
If complex position location systems are implemented to improve accuracy, then positioning precision may be improved, but the systems become less simple and more computationally demanding
Solution Approach 1:
The patent uses distinct visual patterns (dark and light blocks) on position indicators that can be easily differentiated by image sensors, achieving high positioning precision through simple optical contrast recognition rather than complex measurement systems
Solution Approach 2:
Multiple position indicators use identical structural designs with unique pattern arrangements, allowing the robot to recognize positions through pattern matching rather than complex coordinate calculations, maintaining precision while simplifying the system
3Adaptability or versatility
If traditional positioning systems are used, then basic positioning can be achieved, but they require extensive calibration or reprogramming across different arena configurations
Solution Approach 1:
The position indicators use a universal coded pattern design that can be deployed in various arena configurations without requiring recalibration, as the robot identifies positions through pattern recognition rather than pre-programmed coordinates, thereby improving adaptability while reducing calibration complexity
Solution Approach 2:
The system enables robots to autonomously identify their positions through real-time recognition of coded patterns, eliminating the need for external calibration processes or reprogramming when arena configurations change
