Accessory Making Device Using Rigid Holder for Cord Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of devices that allow children to easily make accessories, specifically scrunchies, with a tubular decoration main body disposed in a contracted state around a ring-shaped core, which has not been previously addressed.
Innovation Solution
An accessory making device featuring a long rigid holder that retains the connecting portions of a stretchable cord-like body, allowing the cord to be inserted through a decoration main body, forming a ring shape, and then adjusted to cover the core, enabling children to create scrunchies with ease.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a device is designed to allow children to easily make scrunchies, then ease of operation is improved, but device complexity increases due to the need for a holder structure that retains cord-like body connecting portions
Solution Approach 1:
A holder is introduced as an intermediary tool that temporarily retains the connecting portions of the cord-like body at separated positions. This holder serves as a mediator between the user's hands and the elastic cord, making it easier for children to insert the cord through the decoration main body without needing to manually coordinate both ends of the elastic cord. After the cord is inserted and connected, the holder is removed.
2Ease of operation
If the holder is made rigid to facilitate insertion through the decoration main body, then ease of operation is improved, but the holder cannot be easily stored when not in use
Solution Approach 1:
The holder is designed with dynamic characteristics - it has rigidity when needed for insertion (maintaining its linear shape to facilitate passing through the decoration main body), but can be bent and deformed for compact storage. The holder's flexibility allows it to transition from a rigid insertion tool to a compact stored form, resolving the contradiction between operational rigidity and storage compactness.
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
The device enables children to simply and effectively create scrunchies by facilitating the insertion and contraction of the decoration main body around the core, making it accessible and enjoyable for them to create their own accessories.
Implementation Method 1
a core formed into a substantially ring shape by connecting both ends of a stretchable cord-like body having rubber-like elasticity

AI summary
An accessory making device (1) of the present invention is a device for making an accessory including a core (83) formed into a substantially ring shape by connecting both ends of a stretchable cord-like body (46) having rubber-like elasticity and a decoration main body (83) disposed around the core in such a manner so as to abut both ends thereof against each other in a contracted state so as to be reduced in axial length. The accessory making device (1) includes a long rigid holder (5). The holder (5) can retain connecting portions (47M, 47F) on both end sides of the cord-like body (46) with the connecting portions (47M, 47F) of the cord-like body (46) separated from each other, and can be inserted through the decoration main body (83).
