Jewelry Closure Device with Hinged Post and Wire Loop Latch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Jewelry closure mechanisms often fail to securely fasten items to the wearer, making them difficult to operate and prone to detachment, as they lack a guaranteed locking mechanism and are hard to open and close.
Innovation Solution
A closure device featuring a post element connected to a hinge at one end of the jewelry and a latch with a loop at the other end, where the post element is inserted between the latch's side wires to securely connect the jewelry, providing a simple and secure fastening mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional closure mechanisms are used, then the jewelry can be fastened to the wearer, but the closure is prone to failure and difficult to ascertain whether effectively closed
Solution Approach 1:
The closure device automatically locks when the post element is inserted through the loop, with the latch wires compressing against the post to secure it in place without requiring additional manual locking actions from the user
Solution Approach 2:
The closure mechanism provides tactile feedback through the compression of latch wires against the post element, allowing the user to verify when the closure is effectively locked by feeling the resistance and secure fit
2Reliability
If traditional closure mechanisms are used, then the jewelry can be attached to the wearer, but the closure is difficult to open and close
Solution Approach 1:
The post element is designed to be movable relative to the latch wires, allowing it to be easily inserted through the loop for closing and pulled out for opening, while the latch wires provide dynamic compression to maintain secure attachment during wear
Solution Approach 2:
The closure device is divided into distinct functional components - the post element for insertion and removal, and the latch wires for securing - allowing independent optimization of each component for both security and ease of operation
3Ease of operation
If simple closure mechanisms are used, then the jewelry can be fastened easily, but they lack guaranteed locking capability
Solution Approach 1:
The closure device automatically locks when the post element is inserted through the loop, with the latch wires compressing against the post to secure it in place without requiring additional manual locking actions from the user
Solution Approach 2:
The latch wires act as an intermediary mechanism between the post element and the loop, providing a guaranteed locking capability through compression and friction while maintaining the simplicity of the insertion motion

AI summary
Closure devices for simply and securely fastening items of jewelry, such as hoop earrings and bracelets, to a body of a wearer are described. The closure device includes a post element and a latch. The post element is movably connected to a hinge, wherein the hinge is attached to a first end of an item of jewelry. The latch includes a first and second side wires, which are joined at a closed end to form a loop. The latch is attached to a second end of the item of jewelry. A width of the loop is less than a width of the post element. The closure device secures the item of jewelry to a person by removably but securely connecting between the first and second ends of the item of jewelry by fastening the post element between the first side wire and second side wire of the loop.
