Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional parking brakes may not ensure safety for vehicles parked on slopes, leading to potential sliding and accidents due to insufficient locking force, especially when drivers are careless.
Innovation Solution
A brake system that integrates a main brake and a parking brake controller, which monitors vehicle movement and increases the locking force of the parking brake using an electromechanical brake, and operates the main brake when necessary to prevent sliding, with features like inclination detection and driver warnings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the parking brake is used alone to hold the vehicle on a slope, then the structure is simple, but the braking force is insufficient and the vehicle may slide
Solution Approach 1:
The patent combines the parking brake and main brake into an integrated brake system that operates as a unified whole. The controller manages both brake types coordinate, allowing the parking brake to provide initial holding force while the main brake supplies additional braking power when needed, thereby achieving reliable slope holding without requiring completely separate systems.
Solution Approach 2:
The brake system is designed so that the same brake components can serve multiple functions. The parking brake mechanism can operate independently for light-duty holding, while also working in conjunction with the main brake for heavier loading conditions. This multi-functionality allows a single integrated system to handle various parking scenarios without increasing overall structural complexity.
2Reliability
If the driver manually monitors and adjusts the parking brake, then the control is simple, but the response time is delayed and safety is compromised
Solution Approach 1:
The system incorporates sensors that continuously monitor vehicle movement, slope angle, and brake status. This feedback is processed by the controller, which automatically adjusts the braking force by coordinating the parking brake and main brake. The closed-loop feedback mechanism ensures real-time response to sliding attempts without requiring manual driver intervention, thereby enhancing safety while implementing practical automation.
Solution Approach 2:
The brake system is designed to monitor and adjust itself automatically without continuous driver input. Once the parking brake is engaged, the system self-monitors for sliding conditions and self-corrects by activating the main brake when needed. This self-service capability ensures consistent safety performance while reducing the automation burden on the driver.
3Reliability
If the main brake is operated continuously to prevent sliding, then the braking force is sufficient, but the energy consumption increases and the brake may overheat
Solution Approach 1:
Instead of continuous main brake operation, the system uses periodic or intermittent activation based on real-time sensor feedback. The main brake is engaged only when the controller detects sliding conditions that exceed the parking brake's holding capacity. This periodic action maintains sufficient braking force to prevent sliding while minimizing energy consumption and avoiding overheating from continuous operation.
Solution Approach 2:
The system applies partial braking action through the parking brake for normal conditions, and only adds excessive main brake force when absolutely necessary to prevent sliding. This staged approach ensures that the main brake operates at minimal necessary levels, reducing energy consumption and thermal load while maintaining adequate sliding prevention capability.
