Wheel Resonator Strap Coupling for Impact-Resistant Rim Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional resonator wheels are prone to breakage due to strong impacts during driving, particularly when encountering potholes, as the insertion groove in the wheel rim is not robust enough to withstand external forces.
Innovation Solution
A device featuring an annular first strap assembled on the wheel rim and a second strap that surrounds flanges of the resonators, providing secure mounting and pressurization to the wheel rim, eliminating the need for a conventional insertion groove and enhancing durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If an insertion groove is formed in the wheel rim to fix the resonator, then the resonator can be mounted on the wheel rim, but the insertion groove portion is prone to breakage under strong impact during driving
Solution Approach 1:
The coupling device is divided into multiple components: a first coupling member that engages with the wheel rim's external circumferential surface, and a second coupling member that engages with the resonator's flange. This segmentation allows each component to be optimized for its specific function, with the first coupling member designed to distribute impact forces around the wheel rim rather than concentrating stress in a single insertion groove.
Solution Approach 2:
The first coupling member acts as an intermediary between the wheel rim and the resonator mounting system. Instead of directly forming an insertion groove in the wheel rim, the first coupling member engages with the external circumferential surface and provides a mounting interface for the resonator, thereby protecting the wheel rim from direct impact forces.
2Ease of manufacture
If an insertion groove is formed in the wheel rim, then the resonator can be fixed, but the wheel rim structure becomes more complex and weight increases
Solution Approach 1:
The coupling function is extracted from the wheel rim itself and implemented through a separate first coupling member. This allows the wheel rim to maintain its original simple structure without requiring additional grooves or modifications, thereby avoiding increased weight while still achieving secure resonator mounting.
3Ease of manufacture
If a conventional insertion groove method is used, then the resonator can be mounted, but the assembly process requires precise groove formation and alignment
Solution Approach 1:
The coupling mechanism changes from a groove-based interference fit to a engagement-based system where the first coupling member engages with the external circumferential surface and the second coupling member engages with the flange. This parameter change in the coupling mechanism allows for greater tolerance in positioning and reduces the precision requirements for manufacturing.

AI summary
A device configured for coupling a resonator to a vehicle wheel, may include an annular first strap assembled with an external circumferential surface of the wheel rim and fixing positions of resonators disposed on the external circumferential surface of the wheel rim; and an annular second strap surrounding second flanges formed at second edge portions of the resonators based on an axial direction of the wheel rim and pressurizing the second flange toward the external circumferential surface of the wheel rim after first flanges, which are formed on second edge portions of the resonators based on an axial direction of the wheel rim, are inserted between the first strap and the external circumferential surface of the wheel rim.
