Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional adhesive agents are used on wall stickers, then strong adhesion is achieved, but the stickers leave stains on walls and are toxic

Engineering Contradiction:

Improveadhesion strengthVSAvoidstains and toxicity

Core Design Contradiction:

StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent replaces chemical adhesion (adhesive agents) with electrostatic adhesion. The adhesive layer is charged to generate electrostatic attraction forces that hold the sticker on smooth surfaces without requiring chemical glues, thereby eliminating stains and toxicity while maintaining strong adhesion

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the fundamental parameter of adhesion from chemical bonding to electrostatic force. By charging the adhesive layer and controlling its electrical properties, the sticker achieves reusable adhesion without the harmful effects of traditional adhesive agents

Inventive Principle:

Principle #35Parameter changes

2Ease of manufacture

If electrostatic stickers are made small in size, then production complexity and costs increase

Engineering Contradiction:

Improveproduction simplicityVSAvoidproduction process complexity

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent divides the sticker into two functional layers: a using layer with invisible printing patterns and an adhesive layer with ions. This segmentation allows each layer to be optimized independently, simplifying the manufacturing process while enabling large-size production

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent changes the physical state and properties of the adhesive layer by introducing ions, transforming it from a passive material to an active electrostatic component. This parameter change enables the sticker to function without complex protective layers, reducing production complexity

Inventive Principle:

Principle #35Parameter changes

3Reliability

If protective layers are added to electrostatic stickers, then static electricity is protected, but manufacturing costs and resource waste increase

Engineering Contradiction:

Improvestatic electricity protectionVSAvoidstorage and transportation complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts and removes the protective layer from the sticker structure. By designing the adhesive layer itself to be reusable and protective through its electrostatic properties, the separate protective layer becomes unnecessary, reducing manufacturing costs and resource waste

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The adhesive layer serves multiple functions simultaneously: it provides adhesion through electrostatic forces, protects the static electricity, and enables reusable attachment. This multi-functionality eliminates the need for separate protective layers

Inventive Principle:

Principle #6Universality (Multi-functionality)
