Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for examining an organism's health status are invasive, painful, and limited in sensitivity, especially for detecting soft tissue infections or inflammation, and are ineffective for organisms with intact skin or non-volatile organic substances.
Innovation Solution
A pliable member with a contact layer, micrometer-sized spherical projections, and biocompatibility channels and reaction layers that absorb and analyze body fluids, allowing for non-invasive detection of health or illness through visible changes or fluorescence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If blood is taken for examination, then health status can be examined, but the organism feels pain and discomfort
Solution Approach 1:
The invention extracts the examination function from invasive blood drawing and relocates it to non-invasive interstitial fluid collection through the pliable member contact layer, eliminating pain while preserving diagnostic capability
Solution Approach 2:
The pliable member acts as an intermediary device between the organism and the examination system, collecting interstitial fluid through the contact layer without direct blood extraction, thereby mediating between non-invasive collection and diagnostic analysis
2Measurement precision
If conventional exudate fluid collection is used, then metabolic substances can be examined, but the method is useless for organisms with intact skin
Solution Approach 1:
The contact layer is designed with micrometer-sized spherical projections that create porous structures capable of passively absorbing interstitial fluid through intact skin, enabling fluid collection without breaking the skin barrier
Solution Approach 2:
The pliable member features localized micrometer-scale spherical projections on the contact layer that create specific absorption zones, enabling targeted interstitial fluid collection from intact skin while maintaining overall device flexibility and comfort
3Measurement precision
If repeated blood drawing is performed, then longitudinal monitoring can be achieved, but the procedure becomes tedious and time consuming
Solution Approach 1:
The pliable member with pre-configured contact layer and micrometer projections is prepared in advance for prolonged wear, enabling continuous passive interstitial fluid collection over time, thereby eliminating repeated procedural interventions and reducing total examination time
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
Enables painless, sensitive, and non-invasive examination of both volatile and non-volatile substances, effectively determining health or illness based on fluid analysis without causing discomfort, even for organisms with intact skin.
Implementation Method 1
the spherical projections for examination are able to collect fluid of the organism as a collected fluid
Implementation Method 2
examining a target substance of the collected fluid from the organism and changing color of a reaction layer or emitting fluorescence
