Solution Overview

Problem

Existing massage devices intended for promoting blood circulation can cause lymph fluid to flow to unintended locations, leading to retention issues.

Innovation Solution

A gas-type lymphatic drainage device comprising a first lymphatic drainage member with a pant-like shape and a second member with a boot-like shape, featuring expandable and contractible gas chambers that are designed to direct lymph fluid from the lower limbs towards the torso, with specific configurations to prevent retention in the crotch and other unintended areas.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a gas-type massage device is used to promote blood circulation, then blood circulation is improved, but lymph fluid may flow to unintended locations causing retention

Engineering Contradiction:

Improveblood circulation promotionVSAvoidlymph fluid retention in unintended locations

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The gas chamber is divided into multiple independent portions (first portion for lower abdomen, second portion for gluteal cleft, third portion for crotch) that can be controlled separately. This segmentation allows selective pressurization of specific body regions to direct lymph flow toward the torso while preventing accumulation in the crotch area.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different portions of the gas chamber are designed with specific functional qualities tailored to their anatomical locations. The third portion covering the crotch is specifically configured to prevent lymph fluid entry, while other portions promote flow toward the torso, creating localized functional zones within a single device.

Inventive Principle:

Principle #3Local quality

2Ease of operation

If the gas chamber expands uniformly, then overall massage effect is improved, but the crotch area may be improperly pressed or lymph fluid may accumulate there

Engineering Contradiction:

Improvemassage effectivenessVSAvoidlymph fluid accumulation in crotch

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The gas chamber transitions from a static uniform structure to a dynamic segmented system where different portions can be pressurized independently. This allows the chamber to adapt its pressure distribution dynamically, applying force to the crotch area when needed while maintaining overall massage effectiveness.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The device is designed to preemptively prevent lymph fluid from entering the crotch area by configuring the third portion to press both sides of the crotch. This preliminary action stops the harmful accumulation before it can occur, rather than attempting to resolve it afterward.

Inventive Principle:

Principle #10Preliminary action

3Area of stationary object

If the first gas chamber is designed to cover the lower abdomen and crotch, then comprehensive coverage is improved, but the crotch area may be pressed causing lymph fluid retention

Engineering Contradiction:

Improvebody coverage areaVSAvoidcrotch pressing causing lymph fluid retention

Core Design Contradiction:

Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The gas chamber is segmented into distinct portions (first portion for lower abdomen, second portion for gluteal cleft, third portion for crotch) that can be controlled independently. This allows comprehensive body coverage while selectively managing pressure in the crotch area to prevent lymph fluid retention.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Each portion of the gas chamber is assigned specific functional qualities appropriate to its anatomical location. The third portion covering the crotch is specifically designed to press both sides of the crotch to prevent lymph fluid entry, while maintaining overall comprehensive coverage of the lower body.

Inventive Principle:

Principle #3Local quality

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Effectively promotes the flow of lymph fluid to the intended location, reducing retention in unintended areas by using expandable and contractible gas chambers that strategically press and release pressure on the body.

AI summary

A gas-type lymphatic drainage device includes a first lymphatic drainage member and a second lymphatic drainage member connected to the first lymphatic drainage member, in which the first lymphatic drainage member includes a first gas chamber expandable and contractible, the second lymphatic drainage member includes a gas chamber group containing gas chambers independently expandable and contractible, the first gas chamber includes a first portion configured to cover at least a part of a lower abdomen of a human body, a second portion extending along a gluteal cleft of the human body, and a third portion located between the first portion and the second portion and configured to cover a crotch of the human body, and when the first gas chamber expands, at least a part of a central portion of the third portion is recessed.
