Solution Overview

Problem

Existing clip earrings with massive annular base bodies are not suitable for easily replacing decorative elements, making them complex and unsuitable for quick changes.

Innovation Solution

A clip earring design featuring a base body with a slot and a spring part that forms a snap fastener, allowing for easy attachment and detachment of decorative elements by pivoting the spring part away from the base body, guiding the element into the slot, and securing it with a spring-loaded closure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a solid ring-shaped base body is used, then the structural strength is improved, but the ease of operation for changing decorative elements deteriorates

Engineering Contradiction:
Improvestructural strengthVSAvoidease of changing decorative elements
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The base body is segmented into two functional parts: a solid ring-shaped base body for structural strength and a separate spring part for operational functionality. This segmentation allows the solid base to maintain strength while the spring mechanism provides easy opening and closing for changing decorative elements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The spring part is designed to be dynamically movable relative to the base body, transitioning between open and closed positions. This dynamic element enables easy operation for attaching and detaching decorative elements while the static solid base maintains structural integrity.

Inventive Principle:
Principle #15Dynamics

2Reliability

If a complex attachment system with multiple components is used, then the reliability of attachment is improved, but the device complexity increases

Engineering Contradiction:
Improvereliability of attachmentVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The spring part combines multiple functions into a single integrated component: it provides the closing force, forms the snap clasp with the base body, and guides the decorative element through its structure. This merging reduces device complexity while maintaining reliable attachment through the snap clasp mechanism.

Inventive Principle:
Principle #5Merging (Combining)

3Stability of the object's composition

If a solid ring-shaped base body is used, then the stability of the structure is improved, but the adaptability for different decorative elements deteriorates

Engineering Contradiction:
Improvestability of structureVSAvoidadaptability for different decorative elements
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

By separating the stable ring-shaped base body from the functional spring part, the design maintains structural stability while the spring mechanism provides adaptability for various decorative elements through its opening and closing motion and guiding features.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The spring part serves multiple functions: providing closing force, forming a snap clasp, guiding decorative elements, and enabling easy attachment/detachment. This multi-functionality allows the same base body structure to accommodate different decorative elements, enhancing versatility while maintaining stability.

Inventive Principle:
Principle #6Universality (Multi-functionality)
