Rotating Earring Locking Mechanism for Secure Tragus Piercing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing earrings that pierce through the tragus often have insecure locking mechanisms, leading to easy earring loss due to instability and difficulty in operation.
Innovation Solution
An earring design featuring a primary and secondary main body with a rotating mechanism, where a fixed ear support and vertical ear pin lock securely through a protrusion system, allowing for easy operation and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pin through the tragus is used to attach the earring, then the earring can be worn on the ear, but the locking mechanism is not secure and the earring can easily fall off
Solution Approach 1:
The primary main body is designed to rotate relative to the secondary main body around a rotation shaft. This dynamic rotation mechanism allows the user to easily switch between locked and unlocked states by simply rotating the primary main body, making the locking operation convenient while maintaining secure locking when engaged.
Solution Approach 2:
A protrusion on the ear pin serves as an intermediary locking element that engages with a corresponding opening on the ear support. This protrusion-opening interaction provides a simple yet effective mechanical locking mechanism that secures the earring without requiring complex operations.
2Reliability
If a locking mechanism is added to secure the earring, then the earring will not easily fall off, but the locking mechanism is not easy for the user to operate
Solution Approach 1:
The rotation mechanism allows the locking state to be changed through simple rotational motion of the primary main body. This dynamic design makes the locking and unlocking operations intuitive and easy to perform while ensuring secure retention when locked.
Solution Approach 2:
The protrusion on the ear pin automatically engages with the opening on the ear support when the primary main body is rotated into the locked position. The mechanism self-locks without requiring additional user actions, making the operation simple while maintaining secure retention.
3Ease of operation
If the primary main body is made rotatable towards the secondary main body, then the user can conveniently unlock the protrusion from the opening, but the device complexity increases
Solution Approach 1:
The earring is divided into two separate main bodies (primary and secondary) that can rotate relative to each other. This segmentation allows the rotation mechanism to be simple and focused, involving only the relative movement between two distinct components, thereby minimizing overall device complexity while improving unlocking convenience.
Solution Approach 2:
The rotation mechanism serves multiple functions: it enables both locking and unlocking operations, and also allows the earring to be worn in different orientations. This multi-functionality reduces the need for separate mechanisms, keeping the overall device complexity low while providing convenient operation.

AI summary
An earring set consisting of a primary and a secondary main body. One end of the primary main body can rotate towards the secondary main body. The other end (of the primary main body) has a fixed ear support, while one end of the secondary main body has a fixed vertical ear pin. The pin can go through the ear support and lock up into a fixed position.
