Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple measurement schemes are provided for distance measurement, then measurement precision is improved, but device complexity increases due to negotiation and selection processes
Solution Approach 1:
The patent implements dynamic selection of measurement schemes based on real-time negotiation between devices. The system adapts the measurement approach (wireless signal only, sound signal only, or combined) according to device capabilities and environmental conditions, resolving the contradiction by making the measurement system flexible rather than fixed
Solution Approach 2:
The patent creates a universal measurement framework that can operate with multiple different schemes (wireless signals, sound signals, or combinations). This multi-functional approach allows the system to achieve high precision across diverse device types and scenarios without requiring each device to be optimized for a single measurement method
2Measurement precision
If wireless signals and sound signals are combined for measurement, then measurement precision is improved, but ease of operation deteriorates due to scheme selection requirements
Solution Approach 1:
The patent enables devices to automatically negotiate and select the appropriate measurement scheme without user intervention. The devices self-determine their capabilities, exchange information, and autonomously choose the best measurement approach, eliminating the operational burden on users while maintaining high precision through scheme selection
3Adaptability or versatility
If negotiation process is implemented between devices, then adaptability is improved, but loss of time increases due to negotiation overhead
Solution Approach 1:
The patent performs capability exchange and scheme negotiation in advance, before the actual distance measurement is needed. By preparing the measurement scheme selection beforehand, the system reduces time loss during critical measurement moments while maintaining high adaptability through pre-negotiated capabilities
