Size-Adjustable Fashion Accessory with Resilient Retainer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fashion accessories like bracelets and necklaces with adjustable clasps can be difficult for children to adjust due to the complexity of disengaging and reengaging the clasp while holding the accessory at the desired position.
Innovation Solution
A size-adjustable fashion accessory featuring an elongated strap with catch features and a retainer that includes a resilient engagement element, allowing for easy adjustment and customization, providing a tactile click or snap when adjusting the loop configuration, and enabling complete removal and reengagement of the strap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional adjustable clasp is used, then the accessory can be adjusted to multiple sizes, but it is difficult for children to disengage and reengage the clasp while holding the accessory at the desired position
Solution Approach 1:
The retainer is divided into distinct functional components: a body portion with an opening and a separate engagement element that resiliently moves. This segmentation allows the engagement element to independently interact with the strap end section, enabling easy engagement and disengagement without requiring complex manual manipulation of the entire clasp mechanism.
Solution Approach 2:
The engagement element is designed to resiliently move away from the strap upon insertion and automatically return to engage the strap end section. This self-service mechanism eliminates the need for precise manual positioning and complex disengagement actions, allowing children to easily adjust the accessory by simply inserting and releasing the strap end.
2Ease of operation
If a resilient engagement element is added to provide tactile feedback, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
The engagement element is integrated with the retainer body as a unified structure, where the engagement element forms part of the retainer assembly. This merging approach provides tactile feedback through the resilient movement while avoiding the complexity of completely separate components, as the engagement element works in conjunction with the retainer body's opening and structure.
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 solution simplifies the adjustment process, making it easier for individuals with poor or developing dexterity, such as children, to customize and wear the accessories as jewelry or decorate other items, while ensuring comfort and wearability.
Implementation Method 1
The retainer includes an engagement element that resiliently moves away from the elongate strap upon insertion and removal of the second end section relative to the retainer and resiliently moves toward the elongated strap to engage at least one of the plurality of catch features

AI summary
A size-adjustable fashion accessory includes an elongated strap having a plurality of catch features, such as raised or depressed features, disposed at spaced locations along a length of the elongated strap. A retainer is disposed at a first end section of the elongated strap that is configured to receive an opposing second end section of the elongated strap to form a loop configuration. The retainer includes an engagement element that resiliently deforms against at least one of the plurality of catch features upon insertion or removal of the second end section, providing a tactile engagement, such as a click or snap, when adjusting the size of the loop configuration. The size-adjustable fashion accessory may include a decorative charm accessory or the like that may be adapted to engage the elongated strap at various locations along its length or at the retainer.
