Emergency Brake Mounting with Locking Lid for Manual Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles require an emergency braking system for safety in confined areas but need a manual driving mode for public roads, necessitating a solution that allows easy disabling of the emergency brake system while protecting it from environmental pollutants and ensuring quick activation.
Innovation Solution
A mounting arrangement with a bracket and pivotable lid for an emergency braking system, incorporating a manual valve and backup brake valve arrangement, allowing easy access and protection, and sensors for mode detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the emergency braking system is protected from environmental pollutants using a closed bracket, then the reliability of the braking system is improved, but the ease of operation for switching between driving modes deteriorates
Solution Approach 1:
The bracket is divided into a stationary protective housing and a movable lid that can be opened to access the manual valve. This segmentation allows the valve to be protected during normal operation while remaining accessible when needed by opening the lid.
Solution Approach 2:
The lid is made movable rather than fixed, allowing it to be opened for valve access and closed for protection. This dynamic element resolves the contradiction by transitioning between protected and accessible states as needed.
2Ease of operation
If the manual valve is easily accessible for mode switching, then the ease of operation is improved, but the risk of unintentional position changes due to vibrations increases
Solution Approach 1:
The lid is designed to lock the manual valve in its current position when closed, preventing vibrations from causing unintentional position changes. This preliminary protective action is taken automatically when the lid is closed.
Solution Approach 2:
The lid acts as an intermediary element between the operator and the manual valve. It provides controlled access while maintaining stability, mediating between the need for accessibility and the need for position stability.
3Ease of operation
If the lid is made pivotable for easy access to the manual valve, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The bracket is segmented into a stationary housing and a movable lid connected by a simple pivot joint. This segmentation allows easy access to the valve while keeping the pivot mechanism simple and straightforward.
