Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual control of brightness and color temperature is implemented, then lighting control functionality is provided, but operation complexity increases
Solution Approach 1:
The lighting system automatically adjusts brightness and color temperature based on ambient light sensing and user presence detection, eliminating the need for manual user intervention. The system serves itself by making intelligent control decisions based on environmental conditions, thereby simplifying operation while maintaining adaptive lighting functionality
Solution Approach 2:
The patent replaces manual mechanical control (physical dimmer switches, remote controllers) with automated sensing and control systems that use photodetectors, pyroelectric sensors, and microprocessors to automatically adjust lighting parameters, reducing the need for user interaction while maintaining control functionality
2Use of energy by moving object
If continuous lighting is provided, then adequate illumination is ensured, but energy consumption increases
Solution Approach 1:
The system uses periodic sensing and automated switching to provide lighting only when needed - turning lights on when darkness is detected or when motion is sensed, and turning them off when ambient light is sufficient or no motion is detected, thereby reducing energy consumption while ensuring adequate illumination during active periods
Solution Approach 2:
The lighting system continuously monitors ambient light levels and user presence through sensing modules, using this feedback information to automatically adjust lighting output - increasing illumination when needed and decreasing or turning off lights when not needed, optimizing energy efficiency while maintaining lighting adequacy
