Fabric Clip With Ratchet Spreading Mechanism

Solution Overview

Problem

Conventional methods for altering fabric articles, such as using needles and threads, often result in permanent changes that are difficult to reverse, require professional skills, and are time-consuming and costly. Additionally, they can damage the fabric and do not allow for temporary adjustments.

Innovation Solution

A clip that clamps fabric layers together to create desired alterations, featuring a quick-release mechanism that allows for easy undoing of modifications without puncturing the fabric, enabling temporary and non-permanent adjustments to fabric articles like garments, bedding, and curtains.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If needle and thread alteration method is used, then permanent alteration is achieved, but the alteration cannot be undone and fabric is damaged

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The alteration system is segmented into two distinct components: a permanent structural modification (fabric cutting/resizing) and a temporary fastening mechanism (clip). The clip can be removed and reused, separating the permanent alteration from the temporary adjustment, thereby avoiding fabric damage while maintaining alteration effectiveness.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The clip acts as an intermediary device between the user and the fabric alteration. Instead of directly altering the fabric with needles and threads, the user applies the clip as a mediator that achieves the desired fit adjustment without causing harmful effects to the fabric structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Manufacturing precision

If needle and thread alteration is performed, then alteration is made, but professional skills and time are required

Engineering Contradiction:
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The clip is designed as a self-service tool that enables users to perform alterations independently without requiring professional tailoring skills. The mechanical夹持 mechanism automatically provides the necessary precision and fit adjustment, eliminating the need for user expertise in needle and thread work while maintaining high alteration quality.

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If needle and thread method is used, then alteration is made, but it is time-consuming and costly

Engineering Contradiction:
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The clip is pre-engineered with precise mechanical features (teeth, cam mechanism, spring tension) that automatically provide accurate fabric gripping and adjustment. This preliminary design of the tool eliminates the need for time-consuming manual needle and thread work, while the spring-loaded mechanism ensures consistent precision across all alterations without requiring user skill or time investment.

Inventive Principle:
Principle #10Preliminary action

AI summary

A clip for fabric includes a pair of pivotally connected jaws which can be opened to accept fabric and closed to grip the fabric. The distal ends of the jaws combine to form a ratchet which allows the jaws to be closed, but once engaged prevents the jaws from re-opening. The proximal ends of the jaws form a spreading mechanism which causes the proximal ends of the jaws to spread apart as the clip clamps down on the fabric. This spreading action results in an even distribution of pressure upon the fabric.
