Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing emergency braking systems are used, then braking capability is provided, but the systems are inefficient and economically unfeasible
Solution Approach 1:
The patent employs a hydraulic system comprising a reservoir, pump, hydraulic cylinder, and fluid to deploy and retract the brake pad. When the emergency brake pedal is depressed, the pump pressurizes the fluid which acts on the hydraulic cylinder to rapidly extend the brake pad against the road surface, providing efficient and reliable emergency braking capability
2Loss of time
If a brake pad is deployed to stop the vehicle quickly, then stopping distance is reduced, but the system complexity increases
Solution Approach 1:
The hydraulic system provides rapid response for brake pad deployment and retraction through fluid pressure control, significantly reducing stopping time while maintaining relatively simple system architecture through the use of standard hydraulic components
Solution Approach 2:
The brake pad is designed with movable components including a pivot point and extendable/retractable structure that allows dynamic adjustment of the brake pad position and contact force with the road surface, enabling quick deployment and retraction movements
3Ease of operation
If multiple components are used for controlled braking, then braking control is improved, but manufacturing cost increases
Solution Approach 1:
The hydraulic system provides precise and controlled braking through fluid pressure regulation, allowing smooth deployment and retraction of the brake pad while using commonly available hydraulic components that are cost-effective and easy to manufacture
Solution Approach 2:
The emergency braking system integrates multiple functions including braking, positioning, and retraction capabilities into a unified hydraulic mechanism, allowing the same system components to perform multiple operations thereby reducing overall system complexity and manufacturing costs
