Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wired power supply is used for motion detection systems, then the system can be permanently installed and connected to an electrical power grid, but the system becomes location-dependent and less versatile
Solution Approach 1:
The patent extracts the power supply function from the fixed electrical grid connection and relocates it to a portable battery pack. This allows the sensor device to be separated from the power grid infrastructure, enabling location-independent operation while maintaining reliable power supply through the extracted battery power source.
Solution Approach 2:
The system is segmented into separate functional modules: a sensor module for motion detection and a battery pack for power supply. These modules can be independently connected or disconnected, allowing the sensor device to operate wirelessly with location flexibility while the battery pack can be recharged or replaced as needed.
2Power
If wired connections are used for power supply, then stable energy delivery is ensured, but installation flexibility and mobility are reduced
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless operational system. The battery pack provides portable power without requiring physical cable connections, and the radio interface enables wireless data transmission, substituting mechanical/electrical connections with wireless communication technology.
3Ease of manufacture
If permanent installation with cabling is used, then the system can be connected to power grid, but the system becomes fixed and less adaptable to different locations
Solution Approach 1:
The battery pack is designed as a universal power source that can be used with multiple sensor devices and potentially other electronic devices. The standardized connection interface allows the same battery pack to serve multiple functions and devices, increasing versatility while maintaining ease of manufacture through standardized components.
