Solution Overview

Problem

Existing anti-static garments fail to effectively dissipate static charge held by electrically conductive fibers to the environment, leading to sudden and uncomfortable discharges.

Innovation Solution

A fabric comprising a combination of uncoated and coated fibers, where the coated fibers are embedded in specific zones to facilitate steady dissipation of electrostatic charge to the environment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If electrically conductive fibers are used throughout the garment, then electrostatic charge dissipation capability is improved, but fabric comfort and breathability deteriorate

Engineering Contradiction:

Improveelectrostatic charge dissipation capabilityVSAvoidfabric comfort and breathability

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by strategically placing electrically conductive fibers only in specific zones where electrostatic charge accumulation is most problematic (underarms, cuffs, collar, waistband), while leaving other areas with natural fibers to maintain comfort and breathability. This localized approach resolves the contradiction by providing ESD protection precisely where needed without compromising overall fabric comfort.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The garment is segmented into different fiber zones: areas with electrically conductive fibers for ESD protection and areas with natural fibers for comfort. This segmentation allows each region to perform its optimal function, resolving the contradiction between ESD capability and fabric comfort.

Inventive Principle:

Principle #1Segmentation

2Reliability

If electrically conductive fibers are distributed uniformly across the garment, then electrostatic charge dissipation is improved, but manufacturing complexity increases

Engineering Contradiction:

Improveelectrostatic charge dissipationVSAvoidmanufacturing complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

Instead of uniform distribution, the patent uses local quality by concentrating conductive fibers in specific high-risk zones. This reduces manufacturing complexity compared to uniform distribution while maintaining effective ESD protection where it matters most.

Inventive Principle:

Principle #3Local quality

AI summary

An electrostatic discharge protection garment for preventing sudden discharges of static electricity includes a shirt made of a fabric formed of a plurality of fibers. Some of the fibers are coated with an electrically conductive material. The coated fibers are in electrical communication with at least some uncoated fibers such that any electrostatic charge accumulated on the uncoated fibers is constantly dissipated to the environment via the electrically conductive material.
