Steering Wheel Emblem Bracket Structure for Secure Logo Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing steering wheel emblems are not firmly fixed, leading to potential separation and movement, which affects the quality and design unity of the emblem.
Innovation Solution
The emblem is designed with a coupling groove on the steering wheel rim and an emblem bracket that includes a stopper and recess system, along with a hook coupling structure and double-sided tape, to securely attach the emblem logo and body, providing a robust fixing mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the emblem is attached using a simple attachment method, then the ease of manufacture is improved, but the reliability of the emblem fixation deteriorates
Solution Approach 1:
The emblem assembly is divided into multiple components: an emblem body, an emblem logo, and an emblem bracket. These segments are separately manufactured and then assembled together, allowing each part to be optimized independently while maintaining overall reliability through their integrated coupling structure
Solution Approach 2:
The emblem logo is nested within the emblem body, and the emblem assembly is nested within the emblem bracket, which in turn is nested within the coupling groove of the steering wheel rim. This nested structure ensures that each component is securely positioned and fixed, preventing displacement while maintaining a compact design
2Reliability
If the emblem is firmly fixed to the steering wheel, then the reliability of the emblem fixation is improved, but the device complexity increases
Solution Approach 1:
The fixing mechanism is segmented into distinct functional elements: the coupling groove in the rim, the emblem bracket with stopping protrusions, and the emblem assembly with stopping recesses. This segmentation allows each element to perform a specific fixing function, achieving reliable fixation through distributed simple structures rather than a single complex mechanism
Solution Approach 2:
The emblem bracket serves as an intermediary component between the steering wheel rim and the emblem assembly. It translates the coupling groove structure into secure fixation points through its stopping protrusions, which engage with the stopping recesses of the emblem assembly, thereby simplifying the overall fixing mechanism while ensuring reliability
3Ease of manufacture
If the emblem structure is simplified for easy manufacturing, then the ease of manufacture is improved, but the emblem may be removed by hand, deteriorating the reliability
Solution Approach 1:
The emblem system is segmented into the rim with coupling groove, the emblem bracket, and the emblem assembly. This segmentation allows each component to be manufactured using simple, standard processes while the collective arrangement of these segments creates a fixation mechanism that prevents manual removal through the engagement of stopping protrusions and recesses
Solution Approach 2:
The nested arrangement of the emblem logo within the emblem body and the emblem assembly within the emblem bracket, which is nested within the coupling groove, creates a layered fixation structure. Each nested level contributes to the overall security of the attachment, ensuring that the emblem cannot be easily removed by hand while keeping individual component manufacturing simple
