Solution Overview

Problem

Existing ornamental components for bracelets and necklaces, such as those using resilient materials, face challenges in securing to elongated members with varying diameters and are prone to damage from significant axial forces, making them difficult to manufacture and maintain.

Innovation Solution

A clip design combining rigid and resilient surfaces that securely attaches to elongated members, allowing for adjustable positioning and protection of the resilient element from damage, featuring a rigid gripping surface and a resilient element that compresses to maintain a secure fit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If resilient material is used for the stopping mechanism, then the clip can securely attach to the elongated member, but the resilient material experiences significant axial forces and is prone to damage

Engineering Contradiction:
Improvesecure attachmentVSAvoidresilient element durability
Core Design Contradiction:
ReliabilityVSStrength

Solution Approach 1:

The gripping surface is made rigid instead of resilient, creating a localized area of enhanced strength and durability. This rigid surface is specifically positioned where contact with the elongated member occurs, allowing it to withstand significant axial forces without damage while the rest of the clip maintains its resilient securing mechanism.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The clip combines resilient material for the overall structure with a rigid gripping surface, creating a composite construction. This allows the clip to benefit from both the elasticity needed for secure attachment and the rigidity needed to resist damage from axial forces.

Inventive Principle:
Principle #40Composite materials

2Adaptability or versatility

If resilient material is used for the stopping mechanism, then the clip can adapt to varying diameters, but the material is difficult to secure and maintain

Engineering Contradiction:
Improveadaptation to varying diametersVSAvoidsecuring resilient material
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The rigid gripping surface is positioned specifically at the contact point with the elongated member, where adaptation to varying diameters is needed. This localized rigid structure provides a stable, maintainable surface that is easier to manufacture and secure compared to using resilient material throughout the entire clip.

Inventive Principle:
Principle #3Local quality

3Adaptability or versatility

If the resilient element is exposed to significant axial forces, then the clip can secure to elongated members with varying diameters, but the resilient element experiences wear and tear

Engineering Contradiction:
Improvesecuring to varying diametersVSAvoidresilient element lifespan
Core Design Contradiction:
Adaptability or versatilityVSDuration of action of stationary object

Solution Approach 1:

The rigid gripping surface is strategically positioned at the point of contact with the elongated member, creating a localized protective zone. This rigid surface bears the brunt of axial forces and wear, while the resilient element remains protected and can continue to provide securing functionality for a longer duration.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The rigid gripping surface acts as a protective barrier that shields the resilient element from direct exposure to significant axial forces and wear. By placing this protective layer in advance, the resilient element's lifespan is extended as it doesn't have to withstand the full force of daily use.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The clip design is easier to manufacture, more durable, and effectively secures to elongated members with varying diameters, reducing wear and tear on the resilient element while maintaining a stable attachment.

Implementation Method 1

Resilient material such as silicone are commonly used for stopping mechanisms. The resilient material will deform when it comes into contact with a bracelet / necklace resulting in a spring force (attempting to restore the original shape of the stopping mechanism) that will releasably secure the ornamental component to a selected position of the bracelet / necklace.

Methodology Applied
Scientific EffectElasticity: Elasticity

Implementation Method 2

The resilient material will deform when it comes into contact with a bracelet / necklace resulting in a spring force (attempting to restore the original shape of the stopping mechanism)

Methodology Applied
Scientific EffectSpring force: Spring

Implementation Method 3

The projections have a layer of friction engaging material to enhance the grasping capabilities of the clip, without damaging the article.

Methodology Applied
Scientific EffectFriction: Friction

AI summary

Disclosed is a clip (100) for a bracelet and/or a necklace. The clip in a closed state having a through hole (102) allowing said clip to wreathe an elongated member (301) of a bracelet and/or necklace. The clip comprises: a first part (120) and a second part (130), the first and second parts being connected by a hinge (101); and a resilient element (150) arranged in the second part. The resilient element comprising a first gripping surface for frictionally gripping a surface (151) of the elongated member. The resilient element being spaced apart from the first part. The first part comprises a rigid second gripping surface (121, 122) for gripping a surface of the elongated member, and the resilient element and the rigid second gripping surface allows the clip to be releasably secured at selected positions along the elongated member and allows said clip in a closed state to be movable along the elongated member, on which it is positioned by exerting a force in the axial direction.
