Solution Overview

Problem

Existing water-based massage devices are limited by fixed jet positioning, leading to cumbersome user movement requirements, splashing, and restricted portability, especially for users with mobility issues and in environments lacking suitable drainage.

Innovation Solution

A dry massage device with a movable fluid inlet and outlet system, allowing directional control of fluid flow relative to the patient without sliding, and incorporating inflatable support members for enhanced maneuverability and rigidity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If water jets are positioned below the water line in a fixed position, then splashing is minimized, but the ability to deliver targeted massage is limited and requires user movement

Engineering Contradiction:
ImprovesplashingVSAvoidtargeted massage capability
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent applies the Dynamics principle by making the water jet movable rather than fixed. The handheld device allows the user to dynamically reposition the jet to different locations on the body, enabling targeted massage while keeping the device stationary relative to the water line, thus minimizing splashing.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent uses an intermediary approach by introducing a handheld device that acts as a mediator between the fixed water supply and the user's body. The device channels water through a controllable nozzle, allowing precise targeting without requiring the user to move their body or the main water system.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If hand-held high pressure water jet is used to enable manipulation of jet position, then targeted massage is facilitated, but large amounts of splashing occur and drainage capabilities are required

Engineering Contradiction:
Improvejet position manipulationVSAvoidsplashing
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent applies Local quality by concentrating the water flow through a focused nozzle rather than allowing diffuse spraying. The handheld device directs water in a controlled stream to the specific target area, minimizing unnecessary splashing while maintaining effective massage pressure at the intended location.

Inventive Principle:
Principle #3Local quality

3Device complexity

If fixed water jet positioning is used, then device simplicity is maintained, but user mobility restrictions prevent effective massage of different body areas

Engineering Contradiction:
Improvedevice simplicityVSAvoidmassage area coverage
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent implements Dynamics by transforming the fixed jet system into a movable handheld device. This allows users with mobility restrictions to easily reposition the jet to massage different body areas without requiring complex mechanical systems, maintaining simplicity while dramatically improving versatility.

Inventive Principle:
Principle #15Dynamics

Applied Scientific Principles

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

AI summary

The application discloses a dry massage device. The dry massage device comprises a main chamber, wherein the main chamber comprises an inlet configured to enable fluid to enter the main chamber, and an outlet configured to enable fluid to exit the main chamber. The main chamber has a surface for contacting the patient. The device is configured such that the direction of the fluid entering the main chamber, relative to the surface for contacting the patient, is changeable by the user 'whilst said surface for contacting the patient remains substantially stationary relative to the patient.
