Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If complex alarm systems with multiple sensors are used, then detection capability is improved, but device complexity increases
Solution Approach 1:
The patent combines the transmitter and receiver functions into a single electrostatic sensor antenna. This single antenna both generates the electrostatic field and detects disturbances in that field, eliminating the need for separate transmitter and receiver components while maintaining effective detection capability.
Solution Approach 2:
The single electrostatic sensor antenna serves multiple functions: it acts as a transmitter generating the electrostatic field, a receiver detecting field disturbances, and an integrated sensor combining both functions. This multi-functionality reduces overall system complexity while preserving detection capabilities.
2Area of stationary object
If multiple antennas are used for comprehensive detection, then coverage area is improved, but device complexity increases
Solution Approach 1:
The patent changes the operational parameters of the single electrostatic sensor antenna, specifically operating it at different frequencies (e.g., 2.4 GHz, 5.8 GHz) to extend its detection coverage. By adjusting frequency parameters, the system achieves comprehensive coverage without adding multiple physical antennas.
3Reliability
If traditional alarm systems are installed, then security function is provided, but ease of manufacture deteriorates
Solution Approach 1:
The patent merges the transmitter and receiver into a single integrated electrostatic sensor antenna, which significantly simplifies installation compared to traditional systems requiring separate components. This integration maintains security functionality while improving ease of manufacture and installation.
