Solution Overview

Problem

Existing operating gloves, particularly those used by fire brigades, are not capable of allowing touchscreen functionality due to their thick material thickness, which prevents a conductive layer from making contact with the skin.

Innovation Solution

A control element made of electrically conductive and flame-resistant material is integrated into the glove, protruding on the side of the glove finger, allowing for touchscreen operation without skin contact.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the glove is made of thick material to provide protection, then the protective properties are improved, but the touchscreen capability deteriorates because the conductive layer cannot contact the skin

Engineering Contradiction:
Improveprotective propertiesVSAvoidtouchscreen capability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces a conductive operating element as an intermediary component that bridges the gap between the thick glove material and the touchscreen. This element protrudes from the glove exterior, allowing direct contact with the touchscreen surface while maintaining the protective thickness of the glove material underneath. The conductive element acts as a mediator that transfers electrical contact to the touchscreen without requiring thin glove material.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention moves the conductive interface from an internal layer (requiring skin contact through thin material) to an external protruding element. By extending the conductive operating element outward from the glove surface, the solution transitions from a two-dimensional layer problem to a three-dimensional protrusion solution, enabling touchscreen interaction while maintaining thick protective material.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If a conductive material layer is sewn onto the fingertip to enable touchscreen operation, then the touchscreen capability is improved, but the glove material thickness must be reduced which deteriorates the protective properties

Engineering Contradiction:
Improvetouchscreen capabilityVSAvoidprotective properties
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The conductive operating element serves as an external intermediary that eliminates the need to compromise glove thickness. Instead of sewing a conductive layer onto thin glove material, the invention uses a standalone conductive element that protrudes from the glove, maintaining both touchscreen capability and adequate protective thickness.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If the control element is placed on top of the fingertip, then the touchscreen operation is simplified, but the element becomes subject to high stress and wear which deteriorates its reliability

Engineering Contradiction:
Improvetouchscreen operationVSAvoidcontrol element durability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent positions the conductive operating element asymmetrically on the side of the fingertip rather than at the top center. This asymmetric placement moves the control element away from the high-stress contact area of the fingertip tip, reducing wear and damage while maintaining effective touchscreen operation capability.

Inventive Principle:
Principle #4Asymmetry
