Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If a radar sensor is integrated into a wall-mounted switch, then presence detection capability is improved, but the device loses traditional switch functionality and user control capability
Solution Approach 1:
The patent combines a radar sensor module and a traditional switch button module into a single integrated wall-mounted device. The housing contains both the sensor that detects presence and the mechanical button that allows manual switching, merging two previously separate functions into one unified device that provides both automated and manual control capabilities
Solution Approach 2:
The integrated switch device provides multiple functions: it can detect presence automatically using the radar sensor to control lighting, and it also allows manual on/off control through the physical button. This multi-functional design makes the device adaptable to different user needs and scenarios, resolving the contradiction between automated detection and user control
2Area of stationary object
If a radar sensor and switch button are integrated in a compact housing, then space efficiency is improved, but energy consumption increases
Solution Approach 1:
The radar sensor operates in periodic pulses rather than continuously, transmitting radar signals at intervals to detect presence. This periodic operation mode reduces overall energy consumption while maintaining effective presence detection capability, allowing the device to stay in low-power state between radar pulses
Solution Approach 2:
The device dynamically adjusts its operational state based on detected presence. When presence is detected, the system activates the switch function and relevant circuits; when no presence is detected, it enters a low-power state. This dynamic operation optimizes energy consumption while maintaining compact form factor
3Extent of automation
If a radar sensor is added to a wall switch, then automation capability is improved, but device complexity increases
Solution Approach 1:
The device is segmented into distinct functional modules: a radar sensor module for presence detection, a switch button module for manual control, and a control circuit module that processes inputs from both modules. This modular segmentation allows each component to perform its specific function independently, simplifying the overall system architecture despite the added automation capability
