Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a sensor module with wireless communication capability is used to enable remote deactivation and sensitivity adjustment, then the ease of operation is improved, but the device complexity and cost increase significantly
Solution Approach 1:
The patent introduces a control gear as an intermediary device that handles wireless communication and processing tasks. The control gear receives wireless signals and communicates with the sensor module through electrical connections, allowing remote operation without requiring the sensor module itself to have wireless communication capabilities. This mediator approach resolves the contradiction by enabling ease of operation while keeping the sensor module simple and cost-effective.
2Device complexity
If the sensor module is deactivated by disconnecting electrical connections, then the sensor module can be deactivated without wireless communication hardware, but the luminaire housing must be opened which poses safety risks and reduces ease of operation
Solution Approach 1:
The control gear serves as an intermediary that enables deactivation through wireless communication. Instead of requiring physical access to disconnect electrical connections, the control gear receives wireless commands and terminates the electrical supply to the sensor module electronically. This resolves the contradiction by maintaining simple sensor module configuration while dramatically improving ease of operation and eliminating safety risks associated with opening luminaire housings.
Solution Approach 2:
The patent replaces the mechanical approach of physically disconnecting electrical connections (requiring opening the luminaire housing) with an electronic control mechanism. The control gear electronically terminates the electrical supply to the sensor module based on wireless commands, substituting mechanical disconnection with electronic control. This resolves the contradiction by maintaining simple hardware configuration while improving operational ease and safety.
3Ease of manufacture
If identical luminaires with integrated sensor modules are used, then the ease of manufacture and maintenance is improved, but false motion detection occurs due to electromagnetic interference from nearby metal objects
Solution Approach 1:
The patent enables dynamic adjustment of sensor module parameters (such as sensitivity and detection thresholds) through wireless communication. When false detections occur due to electromagnetic interference from nearby metal objects, the sensitivity parameters can be adjusted or the sensor module can be deactivated remotely. This resolves the contradiction by maintaining identical luminaire design for ease of manufacture while providing flexibility to adjust detection parameters to ensure reliability in different installation environments.
4Measurement precision
If the sensor module sensitivity is adjusted using DIP switches, then the measurement precision can be improved, but the luminaire housing must be opened which reduces ease of operation and poses safety risks
Solution Approach 1:
The patent replaces the mechanical DIP switch adjustment mechanism with an electronic control system. The control gear receives wireless commands and adjusts the sensor module sensitivity parameters electronically through electrical connections, eliminating the need to physically access DIP switches inside the luminaire housing. This resolves the contradiction by maintaining precise sensitivity adjustment capability while dramatically improving ease of operation and eliminating safety risks associated with opening luminaire housings.
