Hinged Fabric Gathering Device with Interchangeable Covers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fabric gathering devices lack a mechanism to easily adjust size and style, and provide secure attachment with user customization options, especially for versatile use with clothing and household items.
Innovation Solution
A fabric gathering device with a hinged clasp having rounded ridges, an aperture, a pin, and a pin cap, allowing for open and closed positions, and interchangeable decorative covers for customization, securely attaching fabric with a pin that can be outside or inside the aperture depending on the position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fabric gathering device uses a simple clasp design, then the device is easy to manufacture and operate, but it lacks the ability to easily adjust size and style
Solution Approach 1:
The clasp is divided into a front half and a back half that can move relative to each other through a hinge connection. This segmentation allows the clasp to transform between open and closed positions, enabling size adjustment and style changes while maintaining a relatively simple overall structure.
Solution Approach 2:
The clasp incorporates a hinge mechanism that enables dynamic movement between fixed positions (open and closed). This dynamic capability allows the device to adapt to different fabric sizes and styles without requiring multiple separate clasps, resolving the contradiction between versatility and structural simplicity.
2Adaptability or versatility
If the device includes interchangeable decorative covers and customization options, then user personalization and style changes are enabled, but the device complexity increases
Solution Approach 1:
The decorative covers serve multiple functions: they provide aesthetic customization, protect the clasp mechanism, and can be easily interchanged to change the device's appearance. This universal component addresses the need for personalization without significantly increasing overall device complexity.
Solution Approach 2:
The decorative covers are designed as separate, easily replaceable components that can be manufactured simply and changed by the user as needed. This approach enables extensive customization options while keeping each individual component simple and the overall system manageable.
3Reliability
If the pin is designed to securely attach fabric within the clasp, then attachment reliability is improved, but user safety may be compromised due to exposed pin
Solution Approach 1:
The pin cap serves as an intermediary element between the functional pin and the user. It provides the necessary protection against user injury while allowing the pin to maintain its fabric-gathering function. The cap can be removed when fabric adjustment is needed and replaced when safety is the priority.
Solution Approach 2:
The pin cap is designed to be removable, allowing the system to dynamically switch between two states: a safe state with the cap on for user protection, and a functional state with the cap off for fabric adjustment. This dynamic configuration resolves the contradiction between safety and attachment reliability.

AI summary
A fabric gathering device including a clasp having a front half hingedly attached to a back half, a plurality of rounded ridges continuously disposed on a front surface of the back half of the clasp, an aperture disposed through the back half of the clasp, a pin disposed on a back surface of the front half of the clasp, and a pin cap removably disposed on an apex of the pin. The clasp has an open position and an alternate closed position. The pin is disposed through the aperture when the clasp is in the closed position. The pin is disposed outside of the aperture when the clasp is in the open position.
