Strap Center Fixed Resonator for Wheel Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional resonators for vehicle wheels are costly and difficult to assemble, with a risk of damage during installation and reduced wheel strength due to the need for a dedicated wide wheel with a fixing groove, leading to increased internal noise and discomfort for vehicle occupants.
Innovation Solution
A strap center fixed type resonator with a resonator body mounted on the wheel rim, featuring a resonating portion and a strap inserting portion on its internal surface, allowing for easy strap insertion to secure the resonator, enhancing assembly and manufacturing efficiency while reducing weight and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated wheel with a fixing groove is used to mount the resonator, then the resonator can be fixed to the wheel, but the production cost increases and the number of assembling processes increases
Solution Approach 1:
The resonator is divided into a body portion and a separate fixing portion that can be independently assembled. The fixing portion includes a strap inserting portion that allows the strap to penetrate through, enabling modular assembly without requiring complex integrated wheel structures.
Solution Approach 2:
A strap is introduced as an intermediary component to connect the resonator to the wheel. The strap passes through the strap inserting portion of the resonator's fixing portion and is secured to the wheel, serving as a mediator that simplifies both the wheel structure and the resonator mounting process.
2Reliability
If a dedicated wheel with a fixing groove is used to mount the resonator, then the resonator can be fixed to the wheel, but the production cost increases
Solution Approach 1:
The resonator is divided into a body portion and a separate fixing portion that can be independently assembled. The fixing portion includes a strap inserting portion that allows the strap to penetrate through, enabling modular assembly without requiring complex integrated wheel structures.
Solution Approach 2:
The strap inserting portion is designed to accommodate standard straps, making the resonator compatible with conventional wheel structures. This universal design allows the same resonator to be mounted on various wheels without requiring dedicated custom wheels, thereby reducing manufacturing costs.
3Ease of operation
If a strap is used to fix the resonator, then the assembly process is simplified, but the resonator may slip or rotate during assembly
Solution Approach 1:
The fixing portion of the resonator is designed with specific local features including the strap inserting portion with precise dimensions and shape. This localized design ensures that the strap fits securely, preventing slipping or rotation during assembly while maintaining overall assembly simplicity.
Solution Approach 2:
The strap inserting portion is designed to guide and constrain the strap during assembly, allowing the strap to self-align and secure the resonator in the correct position. The geometric features of the inserting portion automatically prevent misalignment and ensure proper orientation without requiring additional alignment procedures.

AI summary
A strap center fixed type resonator may include a resonator body configured to be mounted on a rim portion of a wheel supporting a tire; a resonating portion formed on a surface of the resonator body; and a strap inserting portion formed on a bottom internal surface of the resonating portion inside the resonating portion to allow a strap to be inserted in the strap inserting portion, wherein the strap is inserted into the strap inserting portion to fix the resonator body to the rim portion of the wheel.
