Button Attachment Structure with Collet and Tabs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Buttons lack a simple and convenient means for securement to host items such as zippers, key-chains, clothing, book bags, and luggage, limiting their practical use.
Innovation Solution
A button engaging and attachment structure comprising a button engaging portion with tabs and a carrier attachment portion, allowing buttons to be securely fastened to a host carrier using a collet that slides under the button engaging tabs, providing a rim for support and easy attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a button is designed with a collet and shell structure, then the button has a three-dimensional appearance and visual appeal, but the button lacks a simple and convenient means for securement to host items
Solution Approach 1:
The button assembly is divided into separate functional components: the button body (with collet and shell for visual appearance) and the attachment mechanism (separate tab or engagement structure). This segmentation allows each component to optimize its specific function without compromising the other, resolving the contradiction between maintaining the three-dimensional appearance and enabling easy attachment to host items.
Solution Approach 2:
An intermediary attachment structure (such as a tab, loop, or engagement mechanism) is introduced between the button and the host item. This intermediary element provides the necessary connection functionality while leaving the button's collet and shell structure intact, thus preserving the three-dimensional appearance while enabling convenient attachment to various host items.
2Reliability
If traditional button attachment methods (pins or bendable tabs) are used, then the button can be secured to host items, but the attachment process is complex and not simple or convenient
Solution Approach 1:
The attachment function is extracted from the button body itself and placed into a separate, dedicated attachment structure. This extracted attachment mechanism (such as a simple tab or loop) is designed specifically for securement purposes, eliminating the need for complex integration within the button body and reducing overall device complexity while maintaining reliable attachment to host items.
Solution Approach 2:
Instead of making the button body itself complex to achieve attachment functionality, the invention inverts the approach by keeping the button body simple and elegant, then adding a separate attachment mechanism that provides the necessary securement. This inversion simplifies the overall design by separating the visual appearance function from the attachment function.
3Ease of operation
If the button collet is made to slide under button engaging tabs, then the attachment is simple and convenient, but the structure becomes more complex
Solution Approach 1:
The button collet is designed to nest under the button engaging tabs, creating a layered structure where the collet fits within the space defined by the tabs. This nesting arrangement provides simple and convenient attachment while the modular nature of the nested structure allows for easy assembly and disassembly, balancing simplicity of operation with manageable structural complexity.
