Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If uniform braking is applied to all wheels, then the braking system is simple to control, but safety and control are reduced on varying terrains
Solution Approach 1:
The braking system is segmented to apply independent braking forces to different wheels based on their individual conditions and the road slope. The processor controls each wheel's brake separately rather than applying uniform braking, allowing optimization for each wheel's traction conditions while maintaining overall system simplicity.
Solution Approach 2:
The system applies different braking characteristics to different wheels based on local conditions such as road slope, surface condition, and wheel characteristics. Each wheel receives tailored braking intervention appropriate to its specific situation, improving overall safety and control on varying terrains.
2Reliability
If dynamic adjustment of braking rates is implemented, then safety and control are enhanced, but the system complexity increases
Solution Approach 1:
The braking system dynamically adjusts braking rates based on real-time sensor data about road slope, surface conditions, and wheel characteristics. The processor continuously monitors conditions and modifies braking application accordingly, enabling the system to adapt to changing terrain conditions while maintaining manageable complexity through automated control.
Solution Approach 2:
The system uses sensor feedback to continuously monitor road slope, surface conditions, and wheel performance, then adjusts braking rates based on this feedback. This closed-loop control enables safe and effective braking on varying terrains while the processor automates the complex decision-making process.
3Device complexity
If braking is applied without considering wheel characteristics, then the braking process is simpler, but traction and control are reduced
Solution Approach 1:
The system tailors braking application to each wheel's specific characteristics such as tire type, inflation pressure, and wear condition. By considering individual wheel properties along with road conditions, the processor optimizes braking force distribution to maximize traction and control for each wheel while maintaining overall system simplicity.
