Solution Overview

Problem

Biodegradable textile products used in landscaping and horticulture often face temperature sensitivity issues, leading to potential damage and degradation due to temperature increases above the glass transition temperature, which affects their stability and functionality.

Innovation Solution

A network layer comprising at least one thermoplastic biodegradable substance with differently colored materials in contact, where the coloration modifies their absorption coefficients, allowing for differential heating and maintaining thermal stability across a wide temperature range.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If biodegradable textile products are used in landscaping, then environmental compatibility is improved, but temperature stability deteriorates due to sensitivity above glass transition temperature

Engineering Contradiction:

Improveenvironmental compatibilityVSAvoidtemperature stability

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent applies local quality by creating different color zones within the textile product - some areas are coloured to absorb radiation and heat, while other areas remain lighter to reflect radiation. This local differentiation allows the product to regulate temperature across different regions, maintaining stability where needed while enabling heat absorption where required for weed control.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent changes the optical parameters (coloration) of the textile product to control its thermal behavior. By varying the coloration from light to dark across different areas, the absorption coefficient is modified locally, enabling the product to dynamically respond to solar radiation and regulate temperature without compromising the biodegradable nature of the material.

Inventive Principle:

Principle #35Parameter changes

2Object-affected harmful factors

If the network layer is coloured to prevent light transmission, then weed control is improved, but temperature increase causes damage to the biodegradable material

Engineering Contradiction:

Improveweed control effectivenessVSAvoidmaterial damage from heat

Core Design Contradiction:

Object-affected harmful factorsVSObject-generated harmful factors

Solution Approach 1:

The patent implements local quality by dividing the textile product into areas with different coloration - some regions are coloured dark to block light for weed control, while other regions are coloured light to reflect heat and protect the biodegradable material from excessive temperature rise, thus preventing material damage.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent converts the potentially harmful effect of solar radiation into a beneficial temperature regulation mechanism. By strategically placing coloured and uncoloured areas, the product uses radiation absorption in controlled zones to warm the soil for weed control while reflecting radiation in other zones to protect the material, turning a harmful factor into a dual-purpose beneficial system.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)
