Rotation Transmission Disc Crosspiece Layout for Lightweight Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rotation transmission discs, such as brake discs and sprockets, face challenges in achieving a balance between light weight and strength, particularly due to varying specifications and layouts required for different utilization conditions.
Innovation Solution
The rotation transmission disc features a design with an outer circumferential portion, center opening, and attachment holes, along with first and second crosspiece portions that intersect at specific angles and arcs, distributing stress evenly and reducing weight through strategic hole placement and curvature adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the rotation transmission disc is made lighter by reducing material, then weight is reduced, but strength and stress resistance deteriorate
Solution Approach 1:
The disc is segmented by forming multiple through-holes in the disc body, dividing the solid structure into multiple regions. This reduces overall material usage and weight while maintaining structural integrity through the carefully positioned holes that avoid high-stress areas.
Solution Approach 2:
The through-holes are designed with curved or rounded shapes rather than sharp corners, and the disc features curved crosspiece portions connecting the holes. This curvature distributes stress more evenly throughout the structure, preventing stress concentration at sharp edges while maintaining weight reduction benefits.
2Reliability
If the disc design is optimized for specific utilization conditions, then performance under those conditions improves, but adaptability to other specifications deteriorates
Solution Approach 1:
The disc design incorporates a universal pattern of through-hole arrangement and crosspiece configuration that can be adapted to multiple utilization conditions. The geometric pattern of holes and connecting pieces creates a versatile structure that maintains structural integrity across different loading scenarios and application types.
Solution Approach 2:
The design allows for parameter adjustments in the through-hole positions, sizes, and spacing to optimize performance for specific conditions while maintaining the overall structural pattern. By varying these parameters within the established design framework, the same basic design can adapt to different weight, strength, and application requirements.

AI summary
A rotation transmission disc includes: an outer circumferential portion on which a load acts when rotation is transmitted; a center opening portion formed inside the outer circumferential portion; and a plurality of attachment holes for attachment of the rotation transmission disc 1 to a rotating element. A first crosspiece portions are formed in each of ranges of divided angles formed by two adjacent attachment holes with respect to a center of the rotation transmission disc. The first crosspiece portion extends from a load point, which is an intersection between a straight line extending in a radial direction to internally divide the divided angles at a predetermined angular ratio and a load radius position of the outer circumferential portion, to one of the attachment holes forming the divided angles. The second crosspiece portion extends from the load point to the other attachment hole of the attachment holes forming the divided angles.
