Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors are used to detect occupancy and environmental conditions, then measurement precision and reliability are improved, but device complexity and difficulty of control increase
Solution Approach 1:
The patent segments the sensor system into multiple independent sensor modules (occupancy sensor, temperature sensor, humidity sensor, weather sensor) with distinct functions. Each sensor operates independently but contributes to the overall control decision through a hierarchical priority system, reducing the complexity of managing multiple sensors simultaneously.
Solution Approach 2:
The patent introduces a sensor priority hierarchy that dynamically changes the weight or priority parameter of different sensors based on predefined rules. This allows the system to adjust which sensor data is more influential in control decisions, simplifying the control logic while maintaining high measurement precision through multiple sensors.
2Ease of operation
If sensor priority hierarchy is implemented to resolve logical contradictions, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The control apparatus uses a sensor priority hierarchy that assigns different priority levels to various sensors. This parameter-based approach simplifies control signal management by automatically determining which sensor data takes precedence, avoiding complex manual configuration while maintaining operational simplicity.
Solution Approach 2:
The system implements automatic conflict resolution through the sensor priority hierarchy, where the control apparatus autonomously determines which sensor signals to follow based on predefined priorities. This self-service mechanism resolves logical contradictions without requiring external intervention or complex decision-making algorithms.
3Adaptability or versatility
If real-time control signals are generated based on multiple sensor inputs, then adaptability is improved, but processing time and energy consumption increase
Solution Approach 1:
The patent segments the control signal generation process into distinct stages corresponding to different sensor types and priority levels. This allows the system to process sensor inputs in an organized manner, improving adaptability while managing processing time efficiently through structured evaluation.
Solution Approach 2:
The sensor priority hierarchy dynamically adjusts the processing priority of different sensor inputs, allowing the system to focus computational resources on the most critical sensors first. This parameter-based prioritization enables real-time adaptability while optimizing processing time by handling high-priority sensor data before lower-priority data.

AI summary
A control method and control apparatus of a smart occupancy sensor system are provided. The control method includes receiving a switch status value of a switch configured to control power of a sensor module and a spatial information value of a space that is a detection target of the sensor module, generating a sensor priority signal based on the received switch status value and the received spatial information value, generating an increase event signal or a decrease event signal based on the sensor priority signal, and generating a new control signal and controlling the sensor module based on the generated new control signal.
