Solution Overview

Problem

Conventional jackets and coats with water-repellent and wind-repellent materials often lack sufficient stretchability and breathability, restricting movement and comfort during physically demanding activities.

Innovation Solution

A composite sleeve design featuring a lower sleeve, an upper sleeve made of flexible and resilient mesh-type material, and a cover sleeve, which provides enhanced breathability and range of motion without compromising insulation, allowing for improved airflow and flexibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If water-repellent and wind-repellent materials are used for jacket/coat construction, then protection from environmental elements is improved, but stretchability and breathability deteriorate

Engineering Contradiction:

Improveprotection from environmental elementsVSAvoidstretchability and breathability

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The jacket is divided into distinct zones with different material properties: water-repellent/wind-repellent materials are used for the torso and lower sleeves where protection is prioritized, while elastic/stretchable materials are used for the upper sleeves and shoulder areas where freedom of movement is critical. This segmentation allows each zone to optimize for its specific functional requirement without compromising the other.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the jacket are assigned different material qualities based on their functional requirements. The upper sleeves and shoulders use highly elastic materials to accommodate arm movement, while the torso uses water-repellent materials for environmental protection. This local differentiation of material properties resolves the contradiction between protection and mobility.

Inventive Principle:

Principle #3Local quality

2Temperature

If thick insulating materials are used for winter jacket construction, then insulation from cold weather is improved, but breathability and range of motion deteriorate

Engineering Contradiction:

Improveinsulation from cold weatherVSAvoidbreathability and range of motion

Core Design Contradiction:

TemperatureVSEase of operation

Solution Approach 1:

The jacket structure segments insulation placement: thick insulating materials are concentrated in the torso where thermal retention is most important, while the upper sleeves use thinner insulation combined with highly elastic stretchable materials. This allows the jacket to maintain warmth in critical areas while preserving mobility in movement-critical areas.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Insulation density varies by body region: high insulation in the torso for maximum warmth, reduced insulation in the upper sleeves where elasticity and range of motion are prioritized. This local variation in insulation quality resolves the contradiction between thermal protection and freedom of movement.

Inventive Principle:

Principle #3Local quality

3Strength

If limited stretchable materials are used for jacket construction, then structural integrity is improved, but flexibility and comfort during physical activity deteriorate

Engineering Contradiction:

Improvestructural integrityVSAvoidflexibility during physical activity

Core Design Contradiction:

StrengthVSAdaptability or versatility

Solution Approach 1:

The jacket uses different material compositions in different zones: structurally robust water-repellent materials in the torso provide structural integrity, while highly elastic stretchable materials in the upper sleeves and shoulders provide flexibility for physical activity. This segmentation allows both structural strength and movement flexibility to coexist.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The jacket employs composite material construction combining water-repellent coatings, insulating layers, and elastic stretchable fabrics in specific configurations. The upper sleeves use composite materials that prioritize elasticity and stretchability, while the torso uses composite materials that prioritize structural integrity and environmental protection. This composite approach resolves the contradiction between strength and flexibility.
