Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If simple ambient light sensing is used to control lighting systems, then the system is easy to operate, but the adaptability to different conditions is limited
Solution Approach 1:
The lighting system integrates multiple sensor types (ambient light sensors, motion sensors, temperature sensors) and multiple control functions (dimming, on/off control, scheduling) into a single unified system. This allows the system to adapt to various conditions (different lighting environments, motion detection, temperature-based control) while maintaining ease of operation through centralized control interfaces and automated decision-making algorithms that process inputs from all sensors.
2Adaptability or versatility
If centralized control and communication subassemblies are added to lighting systems, then the adaptability and control capability are improved, but the device complexity increases
Solution Approach 1:
The lighting system is divided into modular subassemblies: light-producing subassemblies, control subassemblies, and communication subassemblies. Each module can be independently configured and controlled. The system uses a hierarchical control structure with local control subassemblies that can operate autonomously and a central command center for coordinated control. This segmentation reduces overall system complexity by allowing independent development, testing, and maintenance of individual modules while maintaining system-wide adaptability.
Solution Approach 2:
The patent introduces communication subassemblies and control subassemblies as intermediary components between sensors and light sources. These intermediaries process sensor data, execute control logic, and manage communication protocols, thereby isolating the complexity of centralized control from individual lighting modules. The communication subassembly acts as a mediator that handles data transmission and reception, allowing the system to achieve high adaptability without requiring complex wiring or control logic in each individual light fixture.
3Use of energy by moving object
If dynamic energization control based on multiple sensors is implemented, then energy use is optimized, but the difficulty of detecting and measuring increases
Solution Approach 1:
The lighting system implements closed-loop feedback control by continuously monitoring ambient light levels, motion detection data, and temperature readings through integrated sensors. The control subassembly processes this feedback information and dynamically adjusts light output accordingly. For example, when ambient light exceeds a threshold, the system automatically reduces or turns off lighting. When motion is detected in a dark environment, the system increases illumination. This feedback mechanism enables energy optimization without requiring complex manual measurement and adjustment procedures.
Solution Approach 2:
The lighting system incorporates self-service capabilities through automated sensor-based control. The integrated sensors continuously monitor environmental conditions and automatically trigger appropriate lighting responses without human intervention. The system self-adjusts based on pre-programmed parameters and real-time sensor data, eliminating the need for manual measurement and control. This self-service approach simplifies operation while enabling sophisticated energy optimization based on multiple sensor inputs.
