Hinged Earring with Self-Locking Pin Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ear jewelry designs, particularly those that use pins for attachment, often lack aesthetic appeal and can be cumbersome to handle, with issues related to proper fixation maintenance and potential loss of parts.
Innovation Solution
A configured earring system featuring a first and second half of a ring connected by a hinge, with a pin and reception openings in a curved lamella of the second half of the ring, providing a secure and easy-to-use fixing system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pin and receiving opening fastening system is used, then the earring is secure and easy to handle, but the risk of accidental loss increases if the fastening is not properly maintained
Solution Approach 1:
The earring fastening system is designed to be self-maintaining through the interaction between the pin with transverse recesses and the receiving opening with a projection. The projection automatically engages with the transverse recesses when the earring is properly assembled, creating a self-locking mechanism that maintains the fastening without requiring user intervention or additional maintenance actions.
Solution Approach 2:
The design incorporates preventive measures by providing multiple transverse recesses in the pin and a corresponding projection in the receiving opening that creates a locking engagement before any potential loss can occur. This beforehand engagement ensures the fastening is secured in advance, preventing accidental loss rather than reacting to it.
2Difficulty of detecting and measuring
If the fastening mechanism is made visible, then it can be easily located, but the aesthetic appeal of the earring is reduced
Solution Approach 1:
The fastening mechanism components (pin and receiving opening) are extracted as separate, discrete elements that can be positioned independently from the main decorative body of the earring. This allows the fastening to be located at the back or in less visible areas, keeping the aesthetic design of the visible portion intact while maintaining easy location and operation of the fastening components.
