Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional security tags are used for theft prevention, then security function is provided, but the tags are visible and can be easily removed or disabled by shoplifters

Engineering Contradiction:

Improvesecurity effectivenessVSAvoidvisibility to thieves

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The security tag is enclosed in a flexible textile sleeve that matches the fabric of the garment, making it invisible and indistinguishable from the surrounding material. This conceals the tag from thieves while maintaining security functionality, directly resolving the contradiction between security effectiveness and visibility.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The textile sleeve acts as an intermediary layer between the electronic security components and the external environment. It provides mechanical protection and concealment while allowing RF signals to pass through, enabling the tag to remain hidden from thieves but detectable by EAS systems.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the security tag is made visible for easy identification, then ease of operation is improved, but security effectiveness deteriorates as thieves can locate and disable the tag

Engineering Contradiction:

Improvetag identificationVSAvoidtheft prevention

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The textile sleeve provides a fabric-covered exterior that matches the garment material, making the tag visually indistinguishable from the surrounding fabric. This eliminates the need for visible identification elements while maintaining security effectiveness by concealing the tag from potential thieves.

Inventive Principle:

Principle #30Flexible shells and thin films

3Object-affected harmful factors

If the security tag is encapsulated within textile sleeve for concealment, then visibility to thieves is reduced, but manufacturing complexity increases

Engineering Contradiction:

Improvevisibility to thievesVSAvoidencapsulation structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The textile sleeve is a simple fabric enclosure that can be seamlessly integrated into garment manufacturing processes. The flexibility of the textile material allows it to conform to the tag components while maintaining a simple, single-piece construction that minimizes manufacturing complexity despite providing comprehensive concealment.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The tag combines electronic components with textile materials to create a composite structure. The textile sleeve serves as both protective enclosure and camouflage, integrating multiple functions (protection, concealment, flexibility) into a single material system that simplifies the overall construction.

Inventive Principle:

Principle #40Composite materials

4Object-affected harmful factors

If the security tag is made flexible for seamless integration into clothing, then concealment is improved, but structural strength may be compromised

Engineering Contradiction:

Improveconcealment in clothingVSAvoidtag durability

Core Design Contradiction:

Object-affected harmful factorsVSStrength

Solution Approach 1:

The tag uses composite construction combining flexible textile materials with rigid electronic components. The textile sleeve provides flexibility and concealment while the internal electronic components maintain structural integrity. The composite structure allows the tag to bend and flex with the garment while remaining durable and functional.

Inventive Principle:

Principle #40Composite materials
