Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional turf is used, then natural grass growth is achieved, but maintenance complexity and cost increase significantly

Engineering Contradiction:

Improveturf durabilityVSAvoidmaintenance complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses artificial turf fibers that are designed to be durable yet replaceable, eliminating the need for complex ongoing maintenance of living grass while providing a cost-effective solution that doesn't require fertilizers, continuous cutting, or pest management

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

2Shape

If artificial turf with fine threads is used, then aesthetic quality improves, but fiber resistance decreases and crushing occurs more easily

Engineering Contradiction:

Improveturf appearanceVSAvoidfiber resistance

Core Design Contradiction:

ShapeVSStrength

Solution Approach 1:

The patent employs composite construction with multiple fiber layers and varying thread diameters, combining fine aesthetic fibers with stronger support fibers to achieve both visual quality and mechanical resistance against crushing and wear

Inventive Principle:

Principle #40Composite materials

3Productivity

If intensive use occurs on artificial turf, then productivity increases, but defibrillation and fiber breakage occur

Engineering Contradiction:

Improvefield usage intensityVSAvoidfiber integrity

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent incorporates infill materials and proper substrate preparation before turf installation to provide cushioning and support, preventing fiber breakage during intensive use by absorbing impact forces and maintaining fiber upright position

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The multi-layer composite structure with varying fiber densities and infill materials distributes wear and stress across different layers, preventing defibrillation and extending the turf's service life under intensive usage conditions

Inventive Principle:

Principle #40Composite materials

4Loss of time

If dirt and debris accumulate on artificial turf, then maintenance time increases, but drainage functionality deteriorates

Engineering Contradiction:

Improvemaintenance timeVSAvoiddrainage blockage

Core Design Contradiction:

Loss of timeVSObject-generated harmful factors

Solution Approach 1:

The patent designs the turf with self-cleaning properties through specific fiber configurations and infill material selection that allow debris to be easily removed through simple brushing or blowing, enabling the system to maintain drainage functionality with minimal maintenance intervention

Inventive Principle:

Principle #25Self-service
