Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple comfort brake levels are provided with different brake parameters, then user experience and braking comfort are improved, but device complexity increases
Solution Approach 1:
The system dynamically adjusts brake parameters (brake pressure and brake pressure change rate) based on the selected comfort brake level. The control module switches between different brake parameter sets corresponding to different comfort levels, making the braking behavior adaptable to user preferences while maintaining manageable system complexity through parameter-based control
Solution Approach 2:
The patent implements multiple comfort brake levels by defining different brake parameter sets, where each level corresponds to specific brake pressure and brake pressure change rate values. By changing these parameters according to user selection, the system achieves varied braking comfort without requiring fundamentally different hardware configurations
2Reliability
If real-time monitoring and adjustment of braking process is implemented, then braking comfort and safety are improved, but use of energy increases
Solution Approach 1:
The comfort brake module continuously monitors the actual braking process by obtaining feedback information about brake pressure and vehicle state. This feedback mechanism enables real-time detection of deviations from expected braking behavior and allows the system to adjust brake parameters accordingly, ensuring safety while optimizing energy usage through intelligent control
3Loss of information
If deviation detection between actual and expected braking processes is added, then user experience is improved, but device complexity increases
Solution Approach 1:
The system detects deviations between actual and expected braking processes by comparing feedback information about actual brake pressure and vehicle state against predetermined braking profiles. This feedback-based deviation detection ensures complete monitoring of the braking process while maintaining relatively simple system architecture through comparative analysis
