Solution Overview

Problem

Conventional RFID labels require multiple layers and a release layer for attachment, making them costly and not environmentally friendly.

Innovation Solution

An RFID label with a siliconized first surface and an untreated second surface carrying the RFID tag and a sticky adhesive layer, eliminating the need for additional layers and allowing direct attachment without a silicone liner.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple layers and a release layer are used for attachment, then the label structure is stable and reliable, but the manufacturing cost increases and environmental impact worsens

Engineering Contradiction:
Improveattachment reliabilityVSAvoidlabel structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent removes the release layer from the conventional RFID label structure. The substrate itself is provided with a release surface that provides sufficient release properties without requiring an additional release layer, thereby simplifying the structure while maintaining attachment reliability

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The substrate serves multiple functions: it provides mechanical support, contains the release surface for attachment, and supports the antenna and IC. This multi-functionality eliminates the need for separate release layers and reduces overall structure complexity

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

2Reliability

If multiple layers and a release layer are used for attachment, then the label structure is stable and reliable, but the manufacturing cost increases

Engineering Contradiction:
Improveattachment reliabilityVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The release layer is extracted/removed from the structure. The substrate is directly provided with a release surface through treatment or coating during manufacturing, eliminating the need to manufacture and assemble a separate release layer, thereby reducing manufacturing cost

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The release surface functionality is merged into the substrate itself. Instead of having a separate release layer as in conventional designs, the substrate is engineered to provide release properties directly, reducing the number of manufacturing steps and material costs

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If multiple layers and a release layer are used for attachment, then the label structure is stable and reliable, but the environmental impact worsens

Engineering Contradiction:
Improveattachment reliabilityVSAvoidmaterial waste
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The release layer is removed from the structure, directly reducing material waste. Fewer layers mean less material consumption and simpler disposal or recycling processes, improving environmental sustainability

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The release functionality is combined with the substrate material itself rather than being a separate layer. This reduces the total amount of material required and simplifies the label structure, leading to reduced material waste and improved environmental performance

Inventive Principle:
Principle #5Merging (Combining)
