Solution Overview
Problem
Traditional methods for attaching buttons to garments are slow, laborious, and prone to detachment, with existing solutions often requiring sewing or metallic components that are not designed for easy reattachment or mass production with common materials.
Innovation Solution
A Button Assembly Kit that uses a fastening structure with resilient gates and terminal elements to trap and secure buttons to garments without sewing or metal crimping, utilizing plastic materials for mass production and featuring piercing cones for easy attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional sewing methods are used to attach buttons, then the attachment is relatively secure, but the process is slow and laborious
Solution Approach 1:
The patent replaces the traditional sewing mechanical system (needle, thread, manual stitching) with a plastic injection molding system. The button and garment are attached through a single-step plastic fastening structure that is molded directly onto the button, eliminating the need for sewing operations while maintaining secure attachment.
Solution Approach 2:
The fastening structure is pre-formed during button manufacturing through injection molding. The plastic fastening elements are created in advance as integral parts of the button, rather than being added separately during garment assembly. This preliminary action enables rapid attachment without time-consuming sewing operations.
2Ease of operation
If threaded buttons are used, then the attachment process is simple, but the buttons tend to detach and fall frequently
Solution Approach 1:
The fastening structure is divided into multiple independent plastic elements (legs, hooks, or anchors) that are distributed around the button perimeter. These segmented elements engage with corresponding features in the garment fabric, creating multiple attachment points that work together to prevent detachment while maintaining simple operation.
Solution Approach 2:
The patent replaces the thread-based mechanical fastening system with an integrated plastic fastening structure. The plastic elements are molded as part of the button and engage with the garment through friction, interlocking, or deformation mechanisms, eliminating the need for threads while providing more secure attachment.
3Reliability
If metallic pedestal crimping is used to attach buttons, then the attachment is robust, but the process requires additional tools and machines
Solution Approach 1:
The patent replaces the metallic crimping system (which requires staplers, crimping tools, and metal pedestals) with a plastic injection molding system. The fastening structure is created through molding processes that are already standard in button manufacturing, eliminating the need for specialized attachment tooling while maintaining robust attachment.
Solution Approach 2:
The invention uses plastic materials for the fastening structure instead of metal components. This material substitution allows the fastening elements to be manufactured using injection molding, a process that requires no additional tools or machines beyond standard plastic processing equipment, thereby reducing device complexity while maintaining attachment robustness.
4Productivity
If existing button assemblies are used, then fast attachment is achieved, but they are not designed for button reattachment
Solution Approach 1:
The fastening structure is designed to be removable and reusable. When a button needs to be reattached, the entire fastening structure can be detached from the garment and transferred to a new button or the same button in a different location. This allows for easy repair and reattachment without requiring new fastening components.
Solution Approach 2:
The plastic fastening structure serves multiple functions: it provides secure attachment to the garment, enables rapid detachment for repair, and can be reused on different buttons or garment locations. This multi-functionality addresses both the need for fast attachment and the need for ease of repair.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates quick, robust, and permanent button attachment to garments without additional tools, ensuring the button remains securely fastened even under strong pulling forces, while being cost-effective and easy to manufacture.
Implementation Method 1
the action of trapping is initiated by a forceful intrusion of the terminal elements each one into a separate trapping mechanism. Each trapping mechanism includes a resilient gate which is attached diagonally to the housing... When a terminal element is inserted into its trapping mechanism and reaches its trapping spot, the bent resilient gate is configured to unbend and be released into a cavity which is engraved into the terminal element.

AI summary
The kit comprises a fastening structure and an anchoring structure. The fastening structure includes two vertical poles which are connected at their top ends by a horizontal bar and are inserted into two apertures of the button. The lower ends of the poles are attached to terminal elements. The anchoring structure comprises two trapping mechanisms which are configured to trap the terminal elements and to prevent them from detachment once they reach their trapping spots. The user places the fastening structure with the button above the doth at the desired location and places the trapping mechanisms below the doth opposite to the terminal elements. Next, the user pushes the poles downwards pierces the doth and permanently traps the terminal elements by inserting them into the trapping mechanisms until they reach their trapping spots in which the resilient gates are released and occupy the cavities of the terminal elements.
