Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brake rotor assemblies face challenges in balancing weight distribution and securing weights under centrifugal forces during rotation, leading to potential instability and movement of brake rotor weights.
Innovation Solution
A brake rotor weight with a serpentine configuration and hook arm design is inserted into gaps between vanes of the brake rotor, utilizing bends and arms to secure itself and resist centrifugal forces, ensuring balanced weight distribution and retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If brake rotor weights are used to balance the assembly, then weight distribution is improved, but the weights may move or become unstable under centrifugal forces during rotation
Solution Approach 1:
The brake rotor weight is divided into multiple segments or sections along its length, with each segment capable of independently engaging with the brake rotor vanes. This segmentation allows the weight to better distribute centrifugal forces across multiple engagement points, preventing movement while maintaining balanced weight distribution.
Solution Approach 2:
The brake rotor weight incorporates flexible or movable elements that can dynamically adjust to centrifugal forces during rotation. The weight features flexible arms or deflectable sections that bend or move under centrifugal load, maintaining continuous contact with the brake rotor vanes to prevent displacement while preserving balancing function.
2Stability of the object's composition
If traditional brake rotor weights are used, then balancing is achieved, but the design complexity and manufacturing cost increase
Solution Approach 1:
The brake rotor weight combines multiple functions into a single integrated component: the balancing mass, the retention mechanism, and the attachment structure are merged into one piece. This eliminates the need for separate retention clips or attachment devices, reducing overall complexity while maintaining effective weight distribution and secure attachment.
Solution Approach 2:
The brake rotor weight is designed to automatically engage and secure itself to the brake rotor vanes through its own structural features, such as self-locking geometry or elastic retention elements. This self-service mechanism eliminates the need for additional fasteners or complex attachment systems, simplifying both the weight design and the overall brake rotor assembly.
3Reliability
If brake rotor weights are secured to prevent movement, then reliability is improved, but the ease of manufacture decreases
Solution Approach 1:
The brake rotor weight utilizes changes in material properties or geometric parameters during manufacturing to achieve secure retention. For example, the weight may be formed with elastic deformation zones that permanently set the retention geometry during a single forming operation, or use heat treatment to create differential expansion that locks the weight in place, achieving reliable retention through parameter changes rather than complex assembly steps.
