Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional sensors are used for movement detection in smart lighting, then the system structure remains simple, but the detection precision and adaptability to dynamic environments deteriorate
Solution Approach 1:
The patent replaces traditional mechanical/optical sensors with an ultra-wideband (UWB) sensor module that uses electromagnetic waves for movement detection. The UWB sensor transmits and receives electromagnetic signals to detect human presence and movement patterns, achieving high detection precision without complex mechanical structures. This substitution resolves the contradiction by providing accurate movement detection through field-based sensing rather than mechanical means.
2Use of energy by moving object
If lighting devices operate without adaptive control, then the device complexity remains low, but the energy efficiency deteriorates
Solution Approach 1:
The patent implements a feedback control mechanism where the UWB sensor continuously monitors movement in the detection area, and the controller adjusts LED illumination based on detected human presence and movement patterns. When movement is detected, lighting is activated or adjusted; when no movement is detected for a predetermined time, lighting is dimmed or turned off. This feedback loop achieves high energy efficiency by dynamically adapting lighting to actual usage conditions.
Solution Approach 2:
The lighting system transitions from static operation to dynamic adaptation based on real-time environmental conditions. The controller dynamically adjusts illumination intensity, color temperature, and timing according to detected human presence and movement patterns. This dynamic behavior enables energy efficiency by ensuring lighting is provided only when and where needed, rather than operating continuously at fixed settings.
3Adaptability or versatility
If fixed illumination settings are used, then the ease of operation remains high, but the adaptability to environmental changes deteriorates
Solution Approach 1:
The patent makes the lighting device universal by enabling it to adapt to multiple different environmental conditions and usage scenarios. The UWB sensor detects various movement patterns (entering, leaving, stationary), and the controller provides different lighting responses appropriate for each scenario. This multi-functionality allows a single device to handle diverse situations without requiring separate control systems for each case.
