Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional sensors are used to detect hand gestures in VR controllers, then the device structure remains simple, but detecting precision deteriorates due to detecting errors
Solution Approach 1:
The detection system is segmented into multiple distance detection units arranged in arrays, with each unit independently measuring distance to contact points. This segmentation allows precise localization of touched areas by comparing measurements from multiple units, resolving the contradiction between precision and complexity through distributed sensing.
Solution Approach 2:
The invention adds a distance measurement dimension to the traditional touch detection system. By measuring not just whether a point is touched but also the distance from multiple detection units to contact points, the system achieves precise finger gesture identification without requiring overly complex sensor arrangements.
2Measurement precision
If multiple distance detection units are added to improve detection precision, then measurement precision improves, but device complexity increases
Solution Approach 1:
The distance detection units serve multiple functions: detecting touched positions, identifying which fingers are contacted, and determining gesture types. This multi-functionality allows the system to achieve high detection precision with a relatively simple structure by making each detection unit versatile rather than specialized.
Solution Approach 2:
The system uses multiple copies of distance detection units arranged in specific patterns. Rather than using a single complex sensor, multiple simpler detection units are deployed to collectively provide precise multi-dimensional measurement capability, reducing individual unit complexity while maintaining overall system precision.
3Measurement precision
If touched position and distance measurement are combined for accurate finger gesture identification, then detection accuracy improves, but calculation complexity increases
Solution Approach 1:
The processor uses feedback from multiple distance detection units to iteratively determine the most likely finger contact configuration. By comparing measured distances with expected distances for different finger gestures, the system accurately identifies gestures while keeping processing complexity manageable through pattern recognition rather than exhaustive calculation.
