Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple sensors and electronic devices are loaded into the vehicle to provide convenience functions and safety features, then the functionality and user convenience are improved, but the power consumption of the vehicle increases
Solution Approach 1:
The patent implements dynamic sensor management where the controller selectively enables or disables sensors based on real-time vehicle operating conditions. The system transitions sensors between active and inactive states dynamically, adjusting the sensing network configuration according to current operational requirements rather than maintaining a static sensor deployment pattern.
Solution Approach 2:
The system changes the operational parameters of sensors by adjusting their enable/disable states based on vehicle situation. The controller modifies sensor activation parameters according to detected conditions such as driving mode, parking state, or safety events, thereby optimizing power consumption while maintaining necessary functionality.
2Reliability
If sensors are continuously activated to ensure continuous safety monitoring and functionality, then the safety and reliability are improved, but the power consumption increases
Solution Approach 1:
The system employs periodic sensing activation where sensors are enabled only during specific operational periods or conditions rather than continuous operation. The controller periodically assesses vehicle state and activates sensors only when required for safety monitoring or functional operation, creating an intermittent rather than continuous sensing pattern.
Solution Approach 2:
The system performs preliminary assessment of vehicle operating conditions before activating sensors. The controller evaluates current state parameters and predicts future sensing requirements, enabling sensors in advance only when conditions indicate they will be needed, rather than maintaining constant sensor activation.
