Modular Jewelry Fastening Device with Elastic Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening and connection devices for jewelry and costume jewelry items are difficult to customize and lack versatility, as they often require permanent fixation methods that compromise aesthetics and functionality, particularly for items made of precious materials.
Innovation Solution
A modular fastening device with movable elements and elastic means, such as helical springs, allows for easy engagement and disengagement of jewelry pieces, enabling customization and interchangeability of components to match different styles and materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If permanent fixation methods (welding, connection rings, burying) are used to attach fastening portions to jewelry ends, then reliability is improved, but adaptability and ease of customization deteriorate
Solution Approach 1:
The fastening device is divided into separate modular components: a first portion attachable to one jewelry end, a second portion attachable to the other end, and a main body connecting them. This segmentation allows each component to be independently customized or replaced without affecting the entire device, resolving the contradiction between permanent fixation reliability and customization adaptability.
Solution Approach 2:
The invention introduces movable elements (such as movable pins or tongues) within the main body that can dynamically adjust between engaged and disengaged positions. This dynamic mechanism allows the connection to be securely fastened when needed while enabling easy modification and customization, bridging the gap between reliability and adaptability.
2Reliability
If permanent fixation methods are used, then connection reliability is improved, but ease of operation deteriorates
Solution Approach 1:
Movable elements within the main body can be shifted between engaged and disengaged positions through simple user actions. This dynamic mechanism maintains secure connection reliability when engaged while enabling easy operation for fastening and unfastening, eliminating the need for complex permanent fixation procedures.
Solution Approach 2:
The fastening device incorporates self-locking mechanisms where the movable elements automatically engage with holding seats to secure the connection without requiring additional tools or complex operations. This self-service feature maintains reliability while significantly improving ease of operation for the end user.
3Adaptability or versatility
If movable elements with elastic means are introduced, then adaptability is improved, but device complexity increases
Solution Approach 1:
By dividing the fastening device into separate portions and a main body, the complexity is distributed across manageable components. Each segment can be independently manufactured and assembled, reducing the overall complexity while maintaining high adaptability through modular reconfiguration.
Solution Approach 2:
The main body is designed as a universal component that can accommodate different movable elements and holding seat configurations. This multi-functional design allows a single main body to work with various portions and customization options, improving adaptability without proportionally increasing complexity.
