Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If vehicle components are placed in various positions around the vehicle, then the components can be accessed through different openings, but the components become difficult to locate and use in low ambient light conditions
Solution Approach 1:
The lighting system is activated in advance based on photosensor detection of low ambient light conditions, before the user attempts to use the electrical device. This preliminary illumination action ensures the component is visible and accessible when needed, resolving the contradiction between component accessibility and visibility in dark environments.
Solution Approach 2:
The system uses the electrical device's own power supply to automatically activate the lighting system through photosensor detection. The component serves itself by providing illumination without requiring external lighting or manual intervention, thereby maintaining ease of operation while compensating for insufficient ambient light.
2Illumination intensity
If a lighting system is added to illuminate the component, then visibility improves, but the device complexity increases
Solution Approach 1:
The lighting system is integrated with the electrical device, sharing the same housing, power supply, and control circuitry. This merging approach provides necessary illumination while minimizing additional complexity by reusing existing components and structures rather than adding completely separate systems.
Solution Approach 2:
The electrical device's power supply serves dual purposes: powering both the electrical device and the lighting system. This self-service approach eliminates the need for separate power sources, reducing overall system complexity while maintaining effective illumination.
3Illumination intensity
If the lighting system provides high illumination, then visibility is improved, but energy consumption increases
Solution Approach 1:
The lighting system dynamically adjusts its operation based on real-time photosensor input and ambient light conditions. The system activates only when needed and modulates illumination levels according to actual requirements, providing high brightness when necessary while minimizing energy consumption during normal operation.
Solution Approach 2:
The system changes the illumination parameter from off to on based on ambient light threshold detection. By dynamically changing the lighting state parameter in response to environmental conditions, the system achieves effective visibility improvement while optimizing energy usage patterns.
