Wheel Member Center-of-Gravity Adjuster for Vibration Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wheel members with balance correction materials on flat surfaces experience unevenness and generate noise during rotation due to concave and convex formations, leading to vibration and wind noise issues.
Innovation Solution
A wheel member design featuring a center-of-gravity adjuster between the flat surfaces of the wheel plate, which adjusts the outer circumference shape to maintain balance and suppress noise generation by positioning the center of gravity on the rotation axis, using a combination of a wheel plate, hub, holding plate, and diffusion plate to distribute weight evenly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If balance correction material is provided on the flat surface of the wheel member, then the center of gravity can be adjusted to maintain balance during high-speed rotation, but unevenness (concave and convex formations) occurs on the surface which generates wind noise during rotation
Solution Approach 1:
The balance correction material is positioned between the front and back surfaces of the wheel plate, utilizing the thickness dimension rather than adding material to the outer surface. This dimensional shift allows weight adjustment without creating surface unevenness that would generate wind noise during rotation.
Solution Approach 2:
The balance correction material is embedded within the wheel plate structure, nested between the front and back surfaces. This nesting approach integrates the weight adjustment function into the existing structure without adding external protrusions or surface irregularities.
2Stability of the object's composition
If balance correction material is added to adjust center of gravity, then vibration can be suppressed during rotation, but the device complexity increases due to additional components and assembly steps
Solution Approach 1:
The balance correction material is integrated directly into the wheel plate by positioning it between the front and back surfaces, merging the balance correction function with the wheel plate structure itself. This eliminates the need for separate balance correction components and reduces assembly complexity.
Solution Approach 2:
The wheel plate is designed to serve multiple functions: it provides the structural wheel component and simultaneously houses the balance correction material between its surfaces. This multi-functionality reduces the need for additional dedicated balance correction parts.
