Solution Overview

Problem

Existing compression stockings are difficult to put on and take off, especially for older individuals with limited strength, and they often do not provide comprehensive therapeutic effects as they typically only reach the knee, lacking sufficient coverage and pressure distribution for the entire leg.

Innovation Solution

A compression stocking designed to enclose the leg from above the knee to the ankle with integrated one or two zippers, made of stretch material, preferably with non-allergenic metal or plastic zippers, featuring a single or dual slider configuration and a stop mechanism to prevent unintentional opening, ensuring ease of use and adequate pressure distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If compression stockings are made to enclose the entire leg from above the knee to the ankle, then the therapeutic effect is improved, but the difficulty of putting on and taking off increases

Engineering Contradiction:
Improvetherapeutic effectVSAvoidusability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The compression stocking is divided into two functional segments: an upper portion that provides therapeutic compression from above the knee to the ankle, and a lower portion with a zipper mechanism that enables easy donning and doffing. This segmentation allows the stocking to maintain full leg coverage for therapeutic effectiveness while incorporating a user-friendly closure system.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If a Velcro fastener is used to improve ease of operation, then putting on and taking off becomes easier, but the closing force is insufficient and the fastener easily opens

Engineering Contradiction:
Improveease of putting on and taking offVSAvoidclosing force
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent replaces the Velcro mechanical fastening system with a zipper mechanism. The zipper provides superior closing force and reliability while maintaining ease of operation. The zipper's interlocking teeth structure ensures secure closure that prevents unintentional opening during wear, unlike the Velcro system which lacks sufficient holding force.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If the compression stocking reaches only the knee, then ease of operation is improved, but the therapeutic effect becomes insufficient

Engineering Contradiction:
Improveease of useVSAvoidtherapeutic effect
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The compression stocking is designed with a segmented structure where the main body extends from above the knee to the ankle to provide comprehensive therapeutic coverage, while a separate zipper portion is integrated to facilitate easy donning and doffing. This segmentation allows the stocking to maintain full leg coverage for therapeutic effectiveness while incorporating a user-friendly closure system.

Inventive Principle:
Principle #1Segmentation

4Ease of manufacture

If traditional compression stockings without zippers are used, then manufacturing simplicity is maintained, but usability for older individuals deteriorates

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidusability for older people
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The zipper acts as an intermediary mechanism that bridges the gap between simple manufacturing and improved usability. It is a well-established, cost-effective component that can be easily integrated into the compression stocking manufacturing process while dramatically improving ease of donning and doffing for older individuals with limited strength.

Inventive Principle:
Principle #24Intermediary (Mediator)
