Solution Overview

Problem

Traditional button fastening methods are time-consuming, require skill and specific tools, and are inconvenient, especially for elderly and disabled individuals, leading to issues with lost buttons and decreased productivity in industries like clothing and packaging.

Innovation Solution

A button fastener system featuring a u-shaped penetrating part with a gripping member and a receiving part, where the gripping member is larger for easier handling and provides a better grip, allowing quick and reliable attachment without the need for sewing, with a hidden retaining mechanism for comfort and minimal visual difference from traditional fastening.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional button fastening methods are used, then buttons can be securely attached to clothing, but the process is time-consuming and requires skill and specific tools

Engineering Contradiction:
Improvebutton attachment securityVSAvoidfastening time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The button fastening system is divided into separate components: a button body and a fastening mechanism that can be attached independently. This allows the button to be secured without requiring traditional sewing, significantly reducing fastening time while maintaining reliability through the interlocking fastening components

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A fastening mechanism acts as an intermediary between the button and the clothing, replacing the traditional thread and needle. This intermediary component enables quick attachment while ensuring secure fastening, eliminating the need for skillful sewing operations

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If traditional button fastening methods are used, then buttons can be attached securely, but multiple utilities and training are required

Engineering Contradiction:
Improvebutton attachment securityVSAvoidfastening complexity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The fastening mechanism is designed to be self-explanatory and self-sufficient, requiring no special tools or training. The components are intuitive to assemble and use, allowing anyone to attach buttons securely without needing to learn traditional sewing techniques or obtain special utilities

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The complex elements of traditional button fastening (needle, thread, sewing skills) are extracted and replaced with a simplified mechanical fastening system. This extraction reduces the operational complexity while maintaining secure attachment through the designed interlocking mechanism

Inventive Principle:
Principle #2Taking out (Extraction)

3Shape

If buttons are made small for traditional fastening, then they are less visible and more aesthetic, but they are difficult to handle

Engineering Contradiction:
Improvebutton sizeVSAvoidhandling ease
Core Design Contradiction:
ShapeVSEase of operation

Solution Approach 1:

The handling difficulty is resolved by adding a dimensional element - a grip member that extends from the button body. This allows the button to remain small and aesthetic while providing a larger surface area for easy handling through the extended grip component

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
