Disc Brake Lining Mounting Indicators for Correct Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disc brake systems do not effectively prevent incorrect installation of brake linings, which can lead to safety issues due to improper positioning or use of non-intended brake linings.
Innovation Solution
A disc brake system with a protective plate assembly and mounting indicators that ensure correct installation by engaging only when the brake lining is properly oriented and positioned relative to the brake disc.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If brake linings are installed in poor visibility conditions with limited installation space, then installation difficulty increases and errors occur more frequently, but adding complex guidance systems increases device complexity
Solution Approach 1:
The patent uses color-coded markings on the brake lining and corresponding colored indicators on the brake carrier to provide visual guidance during installation. Different colors indicate different installation positions or orientations, enabling installers to quickly identify correct placement even in poor visibility conditions without adding mechanical complexity
Solution Approach 2:
The patent introduces visual indicators and markings as intermediary elements between the brake lining and brake carrier. These indicators serve as a communication medium that guides the installer in achieving correct alignment and positioning without requiring complex mechanical guidance systems
2Reliability
If additional encoding structures are created during machining of supporting surfaces, then only intended brake linings can be inserted, but this increases manufacturing complexity and production time
Solution Approach 1:
The patent employs asymmetrical geometric features such as offset mounting holes, non-symmetrical support surfaces, or asymmetric positioning elements on the brake carrier that correspond to asymmetrical features on the brake lining. This asymmetric design ensures that only the correct brake lining can be properly installed while using standard machining processes
Solution Approach 2:
The patent incorporates positioning features and guidance elements into the brake carrier design during the initial manufacturing stage. These pre-built features automatically guide the brake lining into the correct position during installation, preventing incorrect installation before it can occur without requiring additional encoding steps
3Reliability
If brake linings are made asymmetrical to prevent 180° rotation, then correct installation position can be ensured, but this reduces adaptability to different installation orientations
Solution Approach 1:
The patent designs the brake lining and brake carrier with complementary asymmetrical features where the brake lining has specific geometric characteristics that only match the brake carrier in the correct orientation. This ensures reliable prevention of incorrect installation while maintaining a standardized design that can be consistently manufactured

AI summary
A disc brake is proposed with a brake carrier and brake linings consisting of a friction lining and a lining rear plate. The brake carrier has a lining well with mutually facing first supporting surfaces and with second supporting surfaces. Angle brackets with tabs are situated between the brake lining and the lining well, of which tabs an inner tab is supported against the inner side and the other tab is supported against the outer side of the brake carrier.
