Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple occupancy sensors are linked and configured for sequential operation, then detection coverage is improved, but device complexity increases
Solution Approach 1:
The beacon device serves multiple functions: it emits beacon signals for position identification, acts as a mobile detection node, and provides spatial reference information. This single device replaces the need for multiple fixed occupancy sensors and their complex linkage configurations, achieving comprehensive detection coverage while simplifying the system architecture.
2Loss of energy
If lights are set with preset timing, then energy conservation is improved, but operational responsiveness deteriorates
Solution Approach 1:
The system continuously monitors the beacon signal presence and strength, providing real-time feedback about user proximity. This enables the control device to dynamically adjust lighting operation based on actual conditions, combining the energy-saving benefits of timing-based control with the responsiveness of real-time detection by implementing preset timing schedules that can be instantly activated or deactivated based on beacon signal feedback.
3Ease of operation
If occupancy sensors are used for automatic light control, then ease of operation is improved, but measurement precision deteriorates
Solution Approach 1:
The patent replaces traditional infrared occupancy sensors with a beacon-based positioning system. Instead of using infrared detection which provides only binary occupancy information, the system uses beacon signal strength and triangulation data to precisely determine spatial position, enabling automatic control with high measurement precision while maintaining ease of operation.

AI summary
A switch controlling system and method of smart appliances are provided. A beacon device is movably located in a space and outputs a beacon signal. Switch devices are located respectively at different positions in the space. The switch device entering within a distance range from the beacon device receives the beacon signal from the beacon device and outputs a distance determined signal according to the beacon signal. A central control device obtains spatial information of the space to establish a spatial database. The central control device looks up the spatial information from the spatial database according to the distance determined signal. The central control device determines a position of the beacon device relative to the electronic devices in the space according to the spatial information. The central control device selectively switches the switch devices to control the electronic devices based on the position of the beacon device.
