Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If battery-powered motion sensors are used for easy retrofittability and mobility, then installation flexibility is improved, but maintenance effort increases due to regular battery replacement
Solution Approach 1:
The patent extracts the power source from portable battery form and connects it to the wall outlet, eliminating the need for battery replacement while maintaining the sensor's operational functionality. This resolves the contradiction by removing the maintenance burden of battery replacement.
Solution Approach 2:
The sensor device is designed to work with standard wall outlets, making it universally compatible with existing electrical infrastructure. This allows the device to gain unlimited power supply while maintaining ease of installation through a single plug-and-play connection.
2Adaptability or versatility
If battery-powered motion sensors are used for mobility and flexibility, then positioning flexibility is improved, but environmental impact worsens due to disposable batteries
Solution Approach 1:
The patent removes the disposable battery component from the system and replaces it with a wall outlet power connection, eliminating the environmental harm associated with battery disposal while preserving the sensor's mobility and positioning flexibility.
3Strength
If drilling or adhesive bonding is used for mounting motion sensors, then secure installation is achieved, but permanent damage occurs from drill holes or adhesive residue
Solution Approach 1:
The patent extracts the mounting function from the sensor device itself and transfers it to the wall outlet, which already provides secure mechanical and electrical connection. This eliminates the need for drilling or adhesive bonding on the wall surface.
Solution Approach 2:
The wall outlet serves as an intermediary that provides both mechanical mounting and electrical power connection. By utilizing this existing infrastructure, the patent avoids direct attachment to the wall surface, preventing permanent damage.
4Reliability
If professional installation in electrical installation box is used for emergency lights with sensor signal converter, then reliable electrical connection is achieved, but installation complexity increases
Solution Approach 1:
The sensor device performs self-installation by simply plugging into a standard wall outlet, eliminating the need for professional electrical installation. The device automatically establishes reliable electrical connection without requiring user intervention in electrical wiring.
