Earring Locking Mechanism with Spring-Loaded Protrusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional earrings have difficulty with precise coupling/decoupling operations, exposing coupling parts and compromising the aesthetic appearance due to their design.
Innovation Solution
An earring design featuring a locking bar with a locking groove and a locker with an insert groove, utilizing either a compression spring for straight movement or a torsion spring for rotational motion, along with a locking release button for easy locking and unlocking, enhancing the aesthetic appeal and usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional coupling parts are used for earrings, then the earring can be assembled, but the coupling/decoupling operation is very difficult and the coupling parts are excessively exposed to the exterior
Solution Approach 1:
The locking protrusion is nested within the locker body, and the locking bar is inserted into the insert groove to engage with the locking protrusion. This nesting arrangement hides the coupling parts inside the earring structure rather than exposing them externally, solving both the difficulty of operation and the aesthetic appearance problem simultaneously.
Solution Approach 2:
The locking protrusion acts as an intermediary element between the locking bar and the locker. It provides a mechanical interface that enables easy coupling/decoupling operation while remaining concealed within the earring structure, thus improving both ease of operation and aesthetic appearance.
2Shape
If conventional coupling parts are used for earrings, then the earring can be assembled, but the coupling parts are excessively exposed to the exterior
Solution Approach 1:
The locking mechanism components (locking protrusion, locking groove) are nested within the earring body structure. The locking protrusion is positioned inside the locker, and the locking bar inserts into the groove to engage with it, keeping all coupling parts concealed and improving aesthetic appearance while maintaining operational ease.
Solution Approach 2:
The locking protrusion serves as a concealed intermediary that enables the coupling operation. It is hidden within the earring structure but provides the necessary mechanical interface for easy locking and unlocking, resolving the contradiction between aesthetics and ease of operation.
3Ease of operation
If the locking protrusion performs straight movement with compression spring, then the locking operation is simplified, but the structural complexity increases
Solution Approach 1:
The compression spring automatically pushes the locking protrusion to engage with or disengage from the locking groove without requiring additional components or complex mechanisms. The spring's elastic force self-regulates the locking operation, simplifying the overall structure while maintaining ease of operation.
4Ease of operation
If the locking protrusion performs rotational motion with torsion spring, then the locking operation is simplified, but the structural complexity increases
Solution Approach 1:
The torsion spring automatically provides rotational force to the locking protrusion, enabling it to engage with or disengage from the locking groove through simple rotational motion. The spring's elastic torque self-regulates the locking operation, simplifying the overall structure while maintaining ease of operation.

AI summary
An earring includes an earring body, a locking bar provided at one end of the earring body and formed with a locking groove, and a locker provided at the other end of the earring body to be selectively locked with the locking bar. The locker is formed with an insert groove, the insert groove is provided at an inside thereof with a locking protrusion, and a locking release button is positioned adjacent to the locking protrusion while protruding out of the locker. The spring includes a compression spring and the locking protrusion is adapted to lock with the locking groove of the locking bar while performing a straight movement in a state in which the locking protrusion is elastically supported to the spring. The locking/unlocking operations of the coupling parts are easily performed and an aesthetic appearance of the earring is improved.
