Jewelry Clasp With Spring Wire Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Jewelry closure mechanisms, particularly those made of gold, tend to weaken and lose functionality with repeated use due to their softer material and lack of springiness, leading to potential accidental opening and loss of expensive jewelry pieces.
Innovation Solution
A secure and reliable closure mechanism featuring a locking receptacle and pin system with precast stainless steel wires that deflect to allow coupling, providing a strong positive lock without the need for double closure mechanisms, and can be used in various jewelry pieces including necklaces, bracelets, and earrings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If jewelry closure mechanisms are made of gold material, then they are aesthetically pleasing and valuable, but they weaken and lose functionality with repeated use due to softer material and less springiness
Solution Approach 1:
The closure mechanism combines two different materials: a gold-colored decorative outer layer (providing aesthetics and value) and a stainless steel inner structure (providing strength, springiness, and reliability). This composite construction allows the mechanism to maintain both aesthetic appeal and functional durability through repeated use.
2Reliability
If a secure locking mechanism is used, then the jewelry remains closed and secure, but it may be difficult to open and use
Solution Approach 1:
The closure mechanism incorporates a spring-loaded pin that dynamically responds to user input. When the user applies pressure to the pin head, the spring compresses and allows the pin to retract, releasing the latch. This dynamic mechanism provides both secure locking (when engaged) and easy opening (when actuated).
Solution Approach 2:
The spring mechanism automatically returns the pin to its locked position after being pressed, providing self-resetting functionality. The user simply needs to press the pin once to open, and the spring automatically re-engages the latch, eliminating the need for complex manual resetting operations.
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 closure mechanism ensures secure and long-lasting functionality, reducing the risk of accidental opening and enhancing user satisfaction by providing an easy-to-use, secure, and durable closure system that withstands repeated use without losing its functionality.
Implementation Method 1
a locking receptacle containing therein at least one spring wire configured to resiliently deflect when the pin head of the locking pin is pushed into the locking receptacle

AI summary
A jewelry closure mechanism (e.g., clasp) may include a locking receptacle and a locking pin that operate together to provide a closure mechanism for a piece of jewelry. The closure mechanism may or may not include a hinge. In some implementations, a locking pin may extend from the second arm and be inserted into a locking receptacle formed in a second arm to lock the two components together. The locking receptacle may include one or more wires (e.g., spring and/or precast) that extend transversely to the direction of the locking receptacle. The closure mechanism may be used as a general jewelry closure device and/or to couple segments of jewelry together.
