Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the illumination device emits light continuously during manual driving state, then visibility and safety are improved, but energy consumption increases
Solution Approach 1:
The illumination device dynamically adjusts its operation mode based on the driving state. During manual driving, the lamp emits light continuously for safety. During autonomous driving, the lamp switches to blinking mode or turns off, reducing energy consumption while maintaining communication functionality.
Solution Approach 2:
The patent implements periodic blinking light emission during autonomous driving state instead of continuous emission. This periodic action maintains visibility and communication with surrounding vehicles while significantly reducing energy consumption compared to continuous lighting.
2Loss of information
If the lamp emits light during autonomous driving state, then communication with other vehicles is improved, but energy efficiency deteriorates
Solution Approach 1:
The illumination device uses periodic blinking light patterns during autonomous driving to communicate vehicle presence and status to other road users. This periodic communication is sufficient for safety while consuming far less energy than continuous light emission.
Solution Approach 2:
The system changes the operational parameters of the illumination device based on driving state. During autonomous driving, the light intensity, duration, and emission pattern are adjusted to provide adequate communication signal while minimizing energy consumption.
3Use of energy by moving object
If the illumination device emits blinking light during autonomous driving, then energy saving is improved, but communication clarity with manually driven vehicles deteriorates
Solution Approach 1:
The blinking light pattern is designed with specific timing and duration parameters that balance energy savings with communication effectiveness. The periodic on-off cycles provide sufficient visual information to manually driven vehicles while maintaining low energy consumption.
Solution Approach 2:
The system monitors the driving state and adjusts the blinking pattern accordingly. When transitioning between manual and autonomous modes, the illumination device adapts its communication pattern to ensure clarity for the current operational context.
