Solution Overview

Problem

Conventional earrings face difficulties in performing locking/unlocking operations of coupling parts, which are also excessively exposed, leading to a compromised aesthetic appearance.

Innovation Solution

An earring design featuring an earring body with a locking groove, an accessory body, a handle, and a spring, where the spring is mounted in the accessory body to elastically lock the earring pin into the accessory body, allowing for easy locking and unlocking by pressing the handle, thereby improving the aesthetic appearance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional coupling parts are used for earring, then the earring can be assembled, but the locking/unlocking operation is very difficult and the coupling parts are excessively exposed to the exterior

Engineering Contradiction:
Improvelocking/unlocking operationVSAvoidaesthetic appearance
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The coupling part is nested within the earring body, with the coupling part housed inside a recessed cavity of the earring body. This nesting arrangement hides the coupling part from external view, improving aesthetic appearance while maintaining functional accessibility through the opening.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

A spring-loaded push button mechanism serves as an intermediary to operate the locking/unlocking of coupling parts. The push button translates user pressure into rotational motion of the coupling part, making the operation easier and more convenient while keeping the coupling part concealed.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the coupling parts are made accessible for easy operation, then the locking/unlocking is facilitated, but the coupling parts become excessively exposed to the exterior

Engineering Contradiction:
Improvecoupling/decoupling operationVSAvoidstructure of coupling mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The coupling part's rotational axis is merged with the longitudinal axis of the earring body, allowing the coupling part to rotate in place within the earring body. This integration simplifies the overall structure by eliminating the need for separate rotating joints or complex mechanisms.

Inventive Principle:
Principle #5Merging (Combining)

3Shape

If the coupling parts are concealed to improve aesthetic appearance, then the earring looks better, but the locking/unlocking operation becomes difficult

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidlocking/unlocking operation
Core Design Contradiction:
ShapeVSEase of operation

Solution Approach 1:

The coupling part is given both rotational freedom around the longitudinal axis and translational freedom along the longitudinal axis. This dual-degree-of-freedom design allows the coupling part to be rotated for locking/unlocking while remaining concealed within the earring body, resolving the contradiction between aesthetics and operability.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

Earring having a body, a pin provided at one end of the body and formed with a locking groove, an accessory body provided at the other end to be locked with the locking groove, a handle and a spring. The spring is to be mounted in the lower portion of the accessory body, and the handle is configured to be fitted within the accessory body such that the spring presses at a first end against the inside of the handle and at a second end against the inside of the accessory body. The accessory body maintains an opening for receiving the pin and is formed with an insert groove within the opening into which the pin is inserted, which is elastically locked with the locking groove of the pin by a spring. When the handle is pressed the upper portion of the accessory body opens and the pin is released.
