Solution Overview

Problem

Conventional methods for producing throws result in limited design options, higher production costs, and environmental concerns due to water, energy, and chemical usage, with varying quality and insulating performance.

Innovation Solution

A method involving knitting an outer fabric with 90%-95% Drawn Texturized Yarn (DTY)/Fully Drawn Yarn (FDY) polyester and 5%-10% spandex, and an inner filling of 100% three-dimensional (3D) poly fill polyester, using a Karl Mayer® warp knitting machine, with dyeing and bleaching procedures to create a squishy and soft throw.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional knitting and processing methods are used to produce throws, then the throws can be manufactured with standard quality, but the production costs increase and design options are limited

Engineering Contradiction:
Improvedesign optionsVSAvoidproduction costs
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent changes the material parameters by using 90%-95% Drawn Texturized Yarn (DTY)/Fully Drawn Yarn (FDY) polyester combined with 5%-10% spandex, and 100% three-dimensional (3D) poly fill polyester for the inner filling. This parameter change enables unique soft and squishy texture while maintaining manufacturing efficiency, resolving the contradiction between design options and production costs

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent employs composite materials by combining polyester and spandex in the outer fabric and using 3D poly fill polyester for the inner filling. This composite approach creates a throw with enhanced softness, squishiness, and insulating performance, providing design flexibility while controlling production costs through optimized material composition

Inventive Principle:
Principle #40Composite materials

2Reliability

If conventional knitting and processing methods are used to produce throws, then the throws can be manufactured with standard quality, but environmental sustainability deteriorates due to extensive water, energy, and chemical usage

Engineering Contradiction:
Improveproduct qualityVSAvoidenvironmental sustainability
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the material composition parameters to use 90%-95% Drawn Texturized Yarn (DTY)/Fully Drawn Yarn (FDY) polyester and 5%-10% spandex, reducing the need for extensive water, energy, and chemical processing while maintaining standard quality. This parameter change improves environmental sustainability by minimizing harmful factors in the manufacturing process

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent employs 100% three-dimensional (3D) poly fill polyester for the inner filling, which provides excellent insulating performance and softness while being cost-effective and environmentally friendly. This material choice reduces the need for complex processing and minimizes environmental impact, aligning with sustainable manufacturing principles

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Reliability

If conventional methods are used to produce throws, then the manufacturing process is established, but the quality and insulating performance vary depending on manufacturing process and materials

Engineering Contradiction:
Improvequality and insulating performanceVSAvoidmanufacturing process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent specifies precise parameter changes: 90%-95% Drawn Texturized Yarn (DTY)/Fully Drawn Yarn (FDY) polyester with 5%-10% spandex for the outer fabric, and 100% three-dimensional (3D) poly fill polyester for the inner filling with GSM ranges of 200-300 for outer fabric and 100-180 for inner filling. These controlled parameter changes ensure consistent quality and insulating performance while simplifying the manufacturing process

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent applies local quality by using different material compositions for the outer fabric and inner filling. The outer fabric uses 90%-95% DTY/FDY polyester with 5%-10% spandex for durability and stretch, while the inner filling uses 100% 3D poly fill polyester for softness and insulation. This localized material optimization ensures high quality and insulating performance throughout the throw while maintaining a relatively simple manufacturing process

Inventive Principle:
Principle #3Local quality
