Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional disc brake devices face installation challenges due to friction blocks hindering or colliding with the disc during assembly, leading to increased complexity, time, and potential damage, affecting safety and performance.
Innovation Solution
The brake lining design features a carrier with a bearing and guide portion, where the guide portion's angle and shape guide the disc into place without collision, ensuring smooth installation and reducing maintenance time, while the friction block is positioned to prevent contact with the disc.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the friction block is positioned to contact the disc for braking, then the braking function is achieved, but the friction block hinders or collides with the disc during installation
Solution Approach 1:
The brake lining is divided into distinct functional segments: the guide portion (with bearing portion and guide portion having specific angular relationships) that facilitates disc installation, and the friction block that provides braking function. This segmentation allows each part to perform its specific function without interfering with the other during different operational phases.
Solution Approach 2:
The guide portion is designed with specific geometric features (bearing portion and guide portion with defined angular relationships) that perform the preliminary action of guiding the disc into proper position during installation, preventing the friction block from contacting the disc before the brake lining is properly installed and positioned.
2Reliability
If the disc brake device has multiple parts and components for effective braking, then the braking performance is improved, but the installation and maintenance become more complicated and time-consuming
Solution Approach 1:
The guide portion and bearing portion are merged into a single integrated structure that performs multiple functions: guiding the disc during installation, positioning the friction block, and ensuring proper alignment. This merging reduces the number of separate components and simplifies the installation process while maintaining effective braking performance.
Solution Approach 2:
The guide portion serves multiple functions: it guides the disc into place during installation, positions the friction block correctly, and ensures proper alignment of the brake lining with the disc. This multi-functionality reduces the need for additional specialized components, thereby reducing installation and maintenance time.
3Power
If the friction block is positioned closer to the disc for better braking contact, then the braking efficiency is improved, but the risk of collision during installation increases
Solution Approach 1:
The guide portion acts as an intermediary between the friction block and the disc during installation. It provides a controlled interface that guides the disc into proper position before the friction block makes contact, preventing direct collision while allowing the friction block to be positioned close to the disc for efficient braking contact.
Solution Approach 2:
The guide portion provides preliminary anti-action by preventing the friction block from contacting the disc during installation through its geometric design (specific angular relationships between bearing portion and guide portion). This preliminary protective action occurs before the actual braking operation, eliminating collision risk while maintaining the ability to achieve close contact for efficient braking.

AI summary
A brake lining of a disc brake device is disclosed, wherein the brake lining includes a carrier and a friction block. The carrier has a bearing portion, which has the friction block provided thereon, and a guide portion connected to an end of the bearing portion. A first virtual line passes through a free end of the guide portion and a junction between the guide portion and the bearing portion, and a second virtual line passes through two opposite points of the disc periphery, wherein an included angle formed therebetween is greater than 0. The smallest possible included angle in any embodiments is formed if the first virtual line passes through an end corner of the friction block. With such design, the disc would not be hindered by nor collide with the friction block during installation, which reduces the difficulty and time for installing or fixing the disc brake device.
