Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If continuous lighting is used to ensure sufficient illumination for night activities, then visibility and safety are improved, but battery life is reduced
Solution Approach 1:
The patent implements periodic action by controlling the light-emitting diodes to illuminate in sequences rather than continuously. The controller activates specific LEDs in predetermined patterns based on motion detection counts, creating intermittent lighting that maintains visibility while conserving battery power.
Solution Approach 2:
The patent applies dynamics by making the lighting pattern adaptive and changeable. The system transitions between different lighting modes (first and second predetermined modes) based on the count of motion-actuated switch signals, allowing the illumination pattern to dynamically adjust to user needs and motion intensity.
2Device complexity
If simple continuous lighting is used, then the device structure remains simple, but the lighting is not noticeable or engaging enough
Solution Approach 1:
The patent makes the lighting system dynamic by implementing multiple predetermined lighting modes that can be switched based on motion detection. The controller varies the illumination patterns across different modes, transforming the static lighting into an adaptive system that responds to user motion and provides engaging visual patterns.
Solution Approach 2:
The patent changes parameters of the lighting system by varying which LEDs are activated and in what sequences. The controller modifies lighting parameters such as which specific diodes illuminate and the timing patterns, creating diverse lighting effects from the same hardware components.
3Reliability
If motion-actuated control with multiple lighting modes is implemented, then lighting visibility and battery conservation are improved, but device complexity increases
Solution Approach 1:
The patent implements self-service by using the motion-actuated switch to automatically detect user movement and trigger appropriate lighting responses without manual intervention. The system monitors motion counts and autonomously selects lighting modes, reducing the need for complex user interfaces while maintaining reliable control.
Solution Approach 2:
The patent applies feedback by using the motion-actuated switch to detect user motion and provide signals to the controller, which then adjusts lighting modes based on the motion count. This closed-loop system ensures reliable lighting control that responds to actual user needs and motion intensity.
