Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional eyelet buttons require deformable materials for press deformation to be fixed on substrates like cloth or leather, making it difficult to exert their function when using materials with poor yield strength or those that cannot be deformed.
Innovation Solution
An eyelet button design featuring an eyelet button body with inverted fasteners and a base plate with protruded tooth portions and clamping grooves, allowing for a fastening structure that fixes the button without deformation, using materials like metal, plastic, wood, ceramics, or glass, and an assembly method involving rotation to secure the button.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If press deformation process is used to fix eyelet button on substrate, then eyelet button can be mounted on cloth or leather, but material must be deformable with good yield strength
Solution Approach 1:
The eyelet button is divided into two separate components: an eyelet button body and a base plate. The base plate with protruded tooth portions engages with inverted fasteners on the eyelet button body through a rotation-based fastening mechanism, eliminating the need for press deformation and enabling use with non-deformable materials.
Solution Approach 2:
Instead of deforming the eyelet button material to achieve fixation, the invention inverts the approach by using pre-formed inverted fasteners that engage with protruded tooth portions through rotation. This reverse mechanism allows fixation without material deformation, expanding material selection to include ceramics, glass, and other non-deformable materials.
2Strength
If deformable material is used for eyelet button, then press deformation mounting is achievable, but materials with poor yield strength or cannot be deformed cannot be used
Solution Approach 1:
The separation of the eyelet button into a body and base plate allows each component to be made from materials optimized for their specific function, without requiring the entire assembly to be made from deformable material. The inverted fasteners and protruded tooth portions enable mechanical engagement independent of material yield strength.
Solution Approach 2:
The invention inverts the traditional mounting approach by using rotation-based engagement of inverted fasteners with protruded tooth portions instead of press deformation. This allows materials with poor yield strength or non-deformable materials like ceramics and glass to be used for the eyelet button body.
3Adaptability or versatility
If rotation-based fastening is used, then non-deformable materials can be fixed, but assembly complexity increases
Solution Approach 1:
The inverted fasteners and protruded tooth portions are integrated into the eyelet button body and base plate respectively, forming a unified rotation-based fastening system. This merging of components simplifies the overall structure while enabling the use of non-deformable materials through rotational engagement.

AI summary
An eyelet button and an assembly method thereof, in which the eyelet button is formed of an eyelet button body and a base plate for fastening with the eyelet button body. The eyelet button body is formed from an eyelet tube, a body peripheral portion formed by everything at one end of the eyelet tube in an axial direction, and a plurality of inverted fasteners formed by everting at the other end of the eyelet tube in the axial direction. The base plate is formed of a base plate body, with a mounting hole with an inner wall having a plurality of protruded tooth portions. A gap is formed between two adjacent protruded tooth portions. When the eyelet tube passes through the mounting hole, the inverted fasteners pass through the gaps to rotate with the eyelet tube so as to be connected and fixed to the corresponding protruded tooth portions.
