Solution Overview

Problem

Existing devices for preventing unwanted conduct of consumer products are costly, require individual modifications, complicate trying on apparel, and risk damaging the product during removal, while not effectively preventing reuse.

Innovation Solution

A tag device with a sticker having adhesive covered by a detachable foil, featuring carved patterns that deform and separate into non-dimensionally stable portions upon detachment, allowing visual detection of reuse.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a strip device is used to prevent unwanted conduct, then the device can indicate usage, but the device must be individually modified to fit each product type which increases complexity and cost

Engineering Contradiction:
Improveusage indication reliabilityVSAvoidindividual modification complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The sticker device is designed as a universal indicator that can be applied to multiple different product types without individual modification. The standardized sticker with adhesive backing and detachment-induced deformation characteristics can indicate usage across various apparel and consumer products, eliminating the need for custom strip devices for each product type.

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

Solution Approach 2:

The sticker is designed as a disposable, low-cost indicator that achieves its function through a single use. The sticker's adhesive layer and backing are configured to create permanent deformation upon removal, providing a reliable usage indication at minimal cost without requiring durable or reusable components.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Reliability

If a strip device is placed inside apparel to prevent unwanted conduct, then it can indicate usage, but it complicates trying on the apparel and makes it uncomfortable for customers

Engineering Contradiction:
Improveusage indication reliabilityVSAvoidtrying on comfort
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The indicator function is extracted from the traditional strip device and implemented through a sticker that can be placed on the exterior or interior surface of apparel without requiring the apparatus to loop through openings or be embedded within the garment structure. This extraction eliminates the physical interference with trying on apparel while maintaining the usage indication function.

Inventive Principle:
Principle #2Taking out (Extraction)

3Reliability

If a narrow strip without pull tab is used to prevent unwanted conduct, then the label can be removed, but the scraping action required to remove the strip risks damaging the product

Engineering Contradiction:
Improvelabel removal capabilityVSAvoidproduct damage risk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The removal mechanism changes from mechanical scraping to adhesive detachment. The sticker's adhesive layer is formulated with specific bonding characteristics that allow clean removal without requiring forceful scraping actions. The parameter change in the adhesive properties enables reliable label removal while eliminating the harmful scraping action that could damage the underlying product surface.

Inventive Principle:
Principle #35Parameter changes

4Reliability

If a sticker with adhesive layer is used to prevent unwanted conduct, then the sticker body can be completely separated from the backing layer, but the sticker may be suitable for specific purposes only and not all applications

Engineering Contradiction:
Improvesticker separation completenessVSAvoidapplication versatility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The sticker device is designed as a universal indicator that can be applied to multiple different product types without individual modification. The standardized sticker with adhesive backing and detachment-induced deformation characteristics can indicate usage across various apparel and consumer products, eliminating the need for custom strip devices for each product type.

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