Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing button attachment methods, such as sewing and metallic crimping, are slow, laborious, and prone to detachment, lacking a fast, robust, and tool-free attachment solution.
Innovation Solution
A button assembly using a trapping mechanism with resilient gates that securely attaches to garment cloth without sewing or metal crimping, employing a terminal element that is trapped within a retaining structure formed by resilient flaps, allowing for easy manual attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional sewing or metallic crimping methods are used to attach buttons, then the attachment is relatively secure, but the process is slow, laborious, and requires additional tools or machines
Solution Approach 1:
The button assembly is divided into separate components: a button body, a resilient retaining structure with gates, and a terminal element. This segmentation allows each component to be independently manufactured and assembled, enabling fast attachment without complex tools or machines while maintaining security through the interlocking mechanism of the resilient gates that engage with the terminal element.
2Strength
If metallic crimping or riveting methods are used, then the button attachment is robust, but the process requires additional tools or machines and is laborious
Solution Approach 1:
The resilient retaining structure with gates is designed to automatically engage and lock the terminal element in place through its own elastic deformation. When the terminal element is inserted, the resilient gates flex and then snap into position, creating a self-locking mechanism that secures the button without requiring external crimping tools, riveting equipment, or additional fastening devices.
3Reliability
If threaded buttons are used, then the attachment can be adjusted, but the buttons tend to detach after intensive use
Solution Approach 1:
The resilient retaining structure incorporates dynamic elements that adapt to stress and movement. The elastic gates can flex under load and then return to their original position, maintaining continuous engagement with the terminal element. This dynamic response allows the attachment to withstand intensive use and strong pulling forces while preventing detachment, as the resilient structure continuously adjusts to maintain secure locking.
4Adaptability or versatility
If standard button attachment methods are used, then the process is simple, but the buttons lack aesthetic versatility and customization options
Solution Approach 1:
The separation of the button body from the retaining structure allows independent design and manufacturing of aesthetic components. The button body can be produced in various colors, shapes, and materials without affecting the functional retaining structure, enabling mass production of standardized functional parts while offering customization options for the visible button elements, thereby reducing overall manufacturing costs.

AI summary
A button assembly configured for fast button attachment to a cloth. The assembly includes button attached to a spacer attached to a pole attached to a terminal element and a separate cone. This configuration is retained by a ring with multiplicity of resilient gates. The terminal element has holding cavity at its bottom end. The cone has a pointed end pointing downwards and a wide upper side with an attached holding pole which facilitates temporary attachment to the terminal element. Piercing the cloth downwards, by the cone followed by the terminal element and the pole bends downwards the resilient gates which are situated beneath the cloth. When the terminal element is inserted below the bent ends of the resilient gates, the gates are released, unbend, and trap the terminal element in the ring. This attaches the button on top of the cloth and the cone is detached and discarded.
