Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional key rings used for attaching labels to products like wire coils and bars are prone to detachment due to wind and air flow during transport, leading to insecure and time-consuming label attachments.

Innovation Solution

A safety lock spring clip with a base portion and projecting legs designed to fit through holes in the label, preventing rotation and ensuring secure attachment by extending through the holes, even in windy conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a conventional key ring is used to attach a label to a product, then the attachment process is simple and quick, but the label may come loose during transport due to wind and air flow

Engineering Contradiction:

Improveease of label attachmentVSAvoidsecurity of label attachment

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The attachment device is divided into distinct functional segments: a base portion that attaches to the product and a projecting leg that extends through the label. This segmentation allows each part to perform its specific function optimally - the base portion provides secure product attachment while the projecting leg prevents label detachment, resolving the contradiction between simple operation and reliable attachment.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The projecting leg is pre-configured to extend through the label in a direction away from the base portion before attachment occurs. This preliminary positioning ensures that once the base portion secures the product, the projecting leg automatically prevents label removal, providing secure attachment without requiring additional操作步骤 after the initial attachment action.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If the label attachment is made secure to prevent detachment during transport, then the attachment becomes more complex and time-consuming

Engineering Contradiction:

Improvesecurity of label attachmentVSAvoidcomplexity of attachment device

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The invention extracts only the essential security function needed to prevent label detachment - a single projecting leg extending through the label. By taking out only this critical element rather than implementing a complex multi-component system, the device achieves reliable attachment prevention while maintaining simplicity in overall structure and operation.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The attachment device appears to be designed as a simple, potentially disposable component with minimal material usage. The projecting leg provides sufficient security function without requiring durable, complex materials or structures, allowing for inexpensive production and efficient disposal after use, thus avoiding complexity while maintaining reliability.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Reliability

If the projecting leg extends through the label to prevent detachment, then the label attachment becomes secure, but the leg may interfere with label positioning

Engineering Contradiction:

Improvesecurity of label attachmentVSAvoidease of label positioning

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

Instead of trying to position the label first and then secure it, the invention inverts the approach by having the projecting leg extend through the label in advance. This inversion allows the label to be positioned naturally without interference, as the projecting leg's extension direction is predetermined to work with rather than against the labeling process, maintaining both security and ease of operation.

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

A safety lock spring clip is intended for attaching a label with at least one through hole to a product. The safety lock spring clip includes a base portion, intended for arrangement to a first through hole and/or a second through hole in the label, and at least one projecting leg extending from the base portion. The at least one projecting leg has an outer end intended to extend through the first through hole or the second through hole in the label when the spring clip is attached to the product and the label, the at least one projecting leg is arranged laterally relative the base portion. The leg has an extension tangentially projecting through the first through hole or the second through hole in the label such that the outer end is at a distance from the first through hole or the second through hole.
