Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing protective clothing lacks effective anchorage points to securely attach portable tools and equipment, risking damage, loss, or injury from accidental drops, especially in elevated or harsh environments.

Innovation Solution

A garment with integrated anchorage points featuring strengthening ribbons and seams, including a loop for attachment, designed to withstand significant forces, using core spun synthetic thread and specific seam types, located at strategic areas like the chest and shoulder for enhanced strength and protection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional protective clothing is used without integrated anchorage points, then the garment structure remains simple, but portable tools and equipment cannot be securely attached, risking damage, loss, or injury from accidental drops

Engineering Contradiction:

Improvesecurity of attachmentVSAvoidgarment structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The anchorage point system is merged with the garment structure by integrating strengthening ribbons directly into the fabric layers. The ribbons are positioned between outer and inner garment layers and secured with stitching, combining the anchorage function with the garment's structural elements rather than adding separate independent components.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The strengthening ribbons serve multiple functions: they provide structural reinforcement for the anchorage point, act as attachment surfaces for portable tools and equipment, and integrate with the garment layers to distribute mechanical loads. This multi-functionality reduces the need for separate specialized components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If anchorage points are added to protective clothing, then secure attachment of tools is enabled, but the garment requires additional strengthening ribbons and complex seam structures

Engineering Contradiction:

Improveanchorage strengthVSAvoidseam and ribbon structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The strengthening ribbons are positioned at specific local areas of the garment where anchorage is needed, rather than reinforcing the entire garment. The ribbons are arranged at angles (including 90-degree configurations) to optimize force distribution at the anchorage point location, providing localized reinforcement where required.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The anchorage structure uses composite construction with multiple fabric layers and strengthening ribbons stitched together. Different seam types (needle cross seams, needle straight seams, bartack stitching seams) are used to create a composite structure that distributes and withholds forces effectively across the anchorage point.

Inventive Principle:

Principle #40Composite materials

3Strength

If strengthening ribbons with thickness of at least 0.5mm and width between 30mm and 100mm are used, then anchorage strength is sufficient to support falling objects, but the garment becomes heavier and more bulky

Engineering Contradiction:

Improveanchorage bearing capacityVSAvoidgarment weight

Core Design Contradiction:

StrengthVSWeight of moving object

Solution Approach 1:

The strengthening ribbons have specific dimensional parameters (thickness of at least 0.5mm, width between 30mm and 100mm) that are optimized to provide sufficient anchorage strength while controlling weight. The ribbons are arranged at specific angles and connected with specific seam types to maximize strength-to-weight ratio.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The use of composite material construction with multiple layers and strategically positioned ribbons allows the garment to achieve high anchorage strength without requiring a uniform increase in material throughout the entire garment, thus minimizing overall weight increase.

Inventive Principle:

Principle #40Composite materials

4Reliability

If multiple seam types (needle cross seams, needle straight seams, bartack stitching seams) are used to connect strengthening ribbons, then force distribution is optimized, but manufacturing complexity increases

Engineering Contradiction:

Improveforce distributionVSAvoidseam fabrication

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The anchorage point is divided into multiple segmented connection points using different seam types. Needle cross seams connect the loop to the anchorage point, needle straight seams connect horizontal strengthening ribbons, and bartack stitching seams connect vertical strengthening ribbons. This segmentation allows each seam type to be optimized for its specific function while distributing forces across multiple connection points.

Inventive Principle:

Principle #1Segmentation
