Brake Force Generator Return Spring Support Ring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brake force generators face challenges during assembly, as the return springs can fall out or become misinserted, increasing assembly effort and error risk.
Innovation Solution
A support ring is integrated into the brake force generator's booster housing to securely hold the return spring in place during assembly, preventing it from falling out and ensuring correct positioning, which is later lifted off after installation and only re-engaged during maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the return spring is supported directly on the control valve without a support ring, then the structure is simple, but the return spring can fall out or become misinserted during assembly
Solution Approach 1:
A support ring is introduced as an intermediary component between the collar and the return spring. The support ring receives the return spring in a receiving region and provides a reliable support surface, preventing the spring from falling out or becoming misinserted during assembly, thus resolving the contradiction between simple structure and assembly safety.
2Reliability
If a support ring with receiving region is added to hold the return spring, then assembly safety is improved, but the device complexity increases
Solution Approach 1:
The support ring is designed to perform multiple functions: it provides a support surface for the return spring, defines a receiving region to hold the spring, and can be integrated with the collar structure. This multi-functionality allows the component to improve assembly safety without proportionally increasing overall device complexity.
Solution Approach 2:
The support ring is designed to nest within the collar structure, with the receiving region of the support ring accommodating the return spring. This nested arrangement allows the support ring to be integrated into the existing collar geometry, minimizing the increase in device complexity while maintaining assembly safety.
