Solution Overview

Problem

Standard needle punched carpets fail to meet specific needs in temporary event settings due to limitations in customization and environmental conditioning, particularly in large areas where they cannot effectively characterize the environment or address specific requirements such as odor control and insect repellence.

Innovation Solution

A functionalized carpet with a polymer-based upper layer of needle punched fibers and a resin-based lower reinforcing layer, incorporating microcapsules that release fragranced, antibacterial, or heat-adjusting substances upon use, and optionally a rubbery base for improved adhesion and liquid barrier, allowing for customization and environmental modification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If standard needle punched carpets are used for temporary events, then production cost is reduced and manufacturing is simplified, but the ability to customize and condition the environment is insufficient

Engineering Contradiction:
Improveproduction cost and manufacturing simplicityVSAvoidcustomization capability and environmental conditioning
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The microcapsules containing functional substances (fragrances, antibacterial agents, heat-adjusting compounds) are incorporated into the carpet during the manufacturing process, specifically within the gaps formed by the needle punching of carded fibres. This preliminary incorporation allows the carpet to be produced in advance with embedded functionality, ready to release substances when deployed at events without requiring additional customization steps.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention changes the chemical and functional parameters of the carpet by incorporating microencapsulated substances that can modify ambient conditions. The microcapsules contain substances that can change fragrance levels, antibacterial properties, and heat adjustment capabilities, transforming a standard carpet into a multi-functional environmental conditioning system.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If microcapsules are incorporated into the needle punched fibres, then environmental conditioning capability is improved, but the structural complexity increases

Engineering Contradiction:
Improveenvironmental conditioning capabilityVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The needle punching process creates a mat of carded fibres with inherent gaps and porosity between the fibres. The invention utilizes this existing porous structure to house the microcapsules, eliminating the need for separate compartments or complex structural modifications. The microcapsules are simply positioned within the naturally occurring gaps in the fibre mat.

Inventive Principle:
Principle #31Porous materials

Solution Approach 2:

The microcapsules are nested within the structure of the needle punched carpet, specifically positioned in the gaps between fibres. This nesting approach integrates the functional elements within the existing carpet structure rather than adding external components, thereby minimizing increases in overall structural complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Area of stationary object

If the carpet is designed for large surface areas, then coverage for events is improved, but the ability to characterize the environment specifically is reduced

Engineering Contradiction:
Improvecarpet coverage areaVSAvoidenvironmental characterization capability
Core Design Contradiction:
Area of stationary objectVSAdaptability or versatility

Solution Approach 1:

The carpet is designed with multi-functional microcapsules that can provide various environmental conditioning effects (fragrance, antibacterial protection, heat adjustment) across large surface areas. This universal design allows a single carpet product to serve multiple event types and environmental needs, maintaining adaptability even at large scales.

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