Solution Overview

Problem

Conventional waterproof pants and boots lack effective warmth preservation, making them inconvenient and burdensome for workers in cold and wet conditions, such as fishing ponds and sewers, leading to increased workload and labor intensity.

Innovation Solution

A multipurpose wearable article comprising a waterproof and breathable body suit, waterproof boots, and a detachable liner member with heating sheets powered by an electrical source, featuring adjustable shoulder straps and compartments for hand warming and storage, designed to be easy to wear and resistant to water and cold.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If workers wear conventional waterproof pants and boots made of rubber material, then water protection is provided, but warmth preservation is insufficient and the clothing becomes heavy and bloated

Engineering Contradiction:
Improvewater protectionVSAvoidwarmth preservation
Core Design Contradiction:
ReliabilityVSTemperature

Solution Approach 1:

The waterproof garment combines rubber material with thermal insulation materials (such as foam or air gap structures) to create a composite structure that provides both water protection and warmth preservation. This allows the garment to maintain waterproofing while adding thermal insulation without using heavy cotton layers.

Inventive Principle:
Principle #40Composite materials

2Temperature

If workers wear thicker cotton socks and trousers for warmth, then warmth preservation improves, but the clothing becomes heavy and bloated, increasing workload and labor intensity

Engineering Contradiction:
Improvewarmth preservationVSAvoidclothing weight
Core Design Contradiction:
TemperatureVSWeight of moving object

Solution Approach 1:

The invention uses thin film or foam insulation materials integrated into the waterproof garment structure, replacing thick cotton layers. These thin insulation films provide adequate warmth while maintaining light weight and flexibility, reducing the burden on workers during movement and work activities.

Inventive Principle:
Principle #30Flexible shells and thin films

3Object-affected harmful factors

If conventional waterproof clothing is used, then water resistance is achieved, but the clothing is heavy and bloated, affecting work efficiency and time

Engineering Contradiction:
Improvewater resistanceVSAvoidwork efficiency
Core Design Contradiction:
Object-affected harmful factorsVSProductivity

Solution Approach 1:

The invention changes the physical parameters of the insulation material by using lightweight foam or air-trap structures instead of dense cotton. This parameter change reduces the weight and bulk of the clothing while maintaining waterproofing, thereby improving worker mobility and work efficiency without compromising water resistance.

Inventive Principle:
Principle #35Parameter changes
