Steering Wheel Rim Covering Split for Wrinkle-Free Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for attaching decorative sections to steering wheel rim sections face challenges in workability and appearance defects due to the need for cutting and dividing the covering member, which complicates the wrapping process and can result in wrinkles.
Innovation Solution
A handle design featuring a grip section with an attaching section where the covering member is split into complementary shapes, allowing for easier alignment and cutting without pre-dividing, thereby improving workability and reducing appearance defects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the covering member is completely divided to expose the attaching section, then the decorative section can be attached to the surface, but the work becomes difficult and wrinkles appear causing appearance defects
Solution Approach 1:
The covering member is divided into two split bodies that are pulled in opposite directions during attachment. This segmentation allows the attaching section to be exposed for decorative section attachment while maintaining the continuity of the covering member, eliminating wrinkles and improving both appearance quality and workability.
2Manufacturing precision
If the covering member is pulled tight to avoid wrinkles, then appearance quality improves, but it becomes difficult to expose the attaching section for decorative attachment
Solution Approach 1:
By dividing the covering member into two split bodies, the patent enables the attaching section to be exposed between the split bodies for decorative section attachment. The split bodies can be pulled tight to avoid wrinkles while the attaching section remains accessible, thus resolving the contradiction between appearance quality and adaptability.
3Ease of manufacture
If the covering member is not divided, then workability improves, but the attaching section cannot be exposed on the surface
Solution Approach 1:
The covering member is divided into two split bodies that can be pulled in opposite directions. This segmentation maintains good workability by allowing easy exposure of the attaching section between the split bodies for decorative section attachment, while the covering member remains substantially continuous.
4Adaptability or versatility
If the covering member is divided into multiple parts to expose attaching sections, then decorative attachment becomes possible, but the process complexity increases
Solution Approach 1:
The patent divides the covering member into two split bodies, which is the minimal segmentation required to expose the attaching section. This simple two-part division enables decorative section attachment while minimizing process complexity compared to more extensive divisions.

AI summary
A steering wheel 1 includes a rim section having a rim section main body section and a covering member that covers at least a part of the rim section main body section. The steering wheel 1 includes a decorative section attached to the rim section. The rim section main body section includes an attaching section to which the decorative section is attached in a direction intersecting a direction in which the rim section main body section extends. The covering member includes one split body and the other split body for covering one part and the other part of the rim section main body section with the attaching section as a reference. The one split body and the other split body are configured such that at least parts of end portions and facing each other in the attaching section have shapes complementary to each other.
