Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Accidental fluid injections from high-pressure hydraulic and diesel systems can be difficult to detect, leading to delayed medical attention and increased tissue damage, as the initial symptoms may be mild and the fluid can spread rapidly through the body, causing severe harm or death if not treated promptly.

Innovation Solution

A fluorescent solution comprising a fluorescent dye and a stabilizing agent, such as monoethanolamine, is added to hydraulic or diesel fluid, allowing for detection under ultraviolet or blue light, which helps locate injected fluid beneath the skin and delays the dispersal or quenching of the dye, facilitating timely medical intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If fluorescent dye is added to hydraulic fluid for detection, then detection capability is improved, but the dye disperses or quenches rapidly causing false negatives

Engineering Contradiction:

Improvedetection capabilityVSAvoiddye stability

Core Design Contradiction:

Measurement precisionVSDuration of action of stationary object

Solution Approach 1:

A stabilizing agent is introduced as an intermediary substance between the fluorescent dye and the hydraulic fluid/biological environment. This stabilizing agent protects the fluorescent dye from dispersal and quenching, maintaining its fluorescent properties throughout the detection period while allowing the dye to fulfill its detection function.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The chemical composition and concentration parameters of the fluorescent solution are optimized to enhance stability. By adjusting the ratio of fluorescent dye to stabilizing agent and selecting specific chemical formulations, the solution maintains fluorescent properties for extended periods without dispersing or quenching, resolving the contradiction between detection capability and duration of action.

Inventive Principle:

Principle #35Parameter changes

2Power

If high pressure hydraulic systems operate at 207 bar, then system power is improved, but fluid injection injury risk increases

Engineering Contradiction:

Improvesystem powerVSAvoidfluid injection injury risk

Core Design Contradiction:

PowerVSObject-affected harmful factors

Solution Approach 1:

The hydraulic fluid is made fluorescent through addition of fluorescent dye, creating a visible color change effect under ultraviolet or blue light. This allows immediate detection of fluid injection injuries that would otherwise be difficult to identify, enabling prompt medical intervention while allowing the high-pressure system to continue operating at its required power level.

Inventive Principle:

Principle #32Color changes

3Measurement precision

If medical practitioners wait for severe symptoms, then diagnostic accuracy is improved, but treatment delay increases causing worse outcomes

Engineering Contradiction:

Improvediagnostic accuracyVSAvoidtreatment delay

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The fluorescent marker is applied in advance to the hydraulic fluid before any injury occurs. This preliminary action ensures that if an injection injury happens, the fluorescent fluid will immediately reveal its presence under appropriate lighting, eliminating the need to wait for severe symptoms to develop and enabling immediate diagnostic action.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The fluorescent property provides continuous visual feedback about the presence and location of injected fluid in the body. This feedback mechanism allows medical practitioners to immediately confirm injection injuries and track fluid migration, enabling timely and accurate treatment decisions without waiting for symptom progression.

Inventive Principle:

Principle #23Feedback
