Handheld Bodily Fluid Test Strip Layout for Hygienic Image Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bodily fluid testing equipment requires a flat surface for analysis, leading to contamination risks and inefficient packaging due to the need for a reference color pad, and lacks user-friendly application methods.
Innovation Solution
A handheld bodily fluid testing equipment with integrated handling indicators and testing regions that allow users to apply bodily fluid and capture image data without placing the equipment on a surface, using a device-based application for analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If application-analysable testing equipment is laid on a flat surface for analysis, then image data can be captured for bodily fluid testing, but contamination risks occur to both the surface and the equipment
Solution Approach 1:
The patent introduces a handheld device with a camera as an intermediary to capture image data of the testing equipment. This eliminates the need to place the testing equipment on a surface, thereby preventing contamination between the bodily fluid, the testing equipment, and the surface. The camera acts as a mediator that transfers the visual information without requiring physical contact between the testing equipment and the surface.
2Measurement precision
If a reference color pad is placed under the testing equipment for analysis, then color comparison can be performed, but packaging efficiency is reduced due to the two-part system
Solution Approach 1:
The patent merges the reference color pad and the testing equipment into a single integrated unit. The reference color pad is positioned adjacent to the testing region on the same handheld device, eliminating the need for a separate reference pad. This integration maintains the color comparison function while significantly reducing packaging volume and improving portability.
3Measurement precision
If reference colours are presented on the testing equipment for analysis, then color-based bodily condition detection can be performed, but the equipment size increases preventing efficient packaging
Solution Approach 1:
The patent implements local quality by positioning the reference color pad in a specific local area adjacent to the testing region, rather than distributing reference colors across the entire equipment. This localized arrangement maintains the necessary color comparison functionality for detecting bodily conditions while minimizing the overall equipment size and enabling efficient packaging.
4Measurement precision
If traditional testing equipment requires multiple components (testing equipment and reference color pad), then comprehensive testing can be performed, but hygiene is compromised due to surface placement
Solution Approach 1:
The patent uses a camera-equipped handheld device as an intermediary to capture image data of the integrated testing equipment. This eliminates the need to place the testing equipment on surfaces, preventing contamination from bodily fluid to the surface and maintaining hygiene. The camera mediator preserves testing accuracy by capturing clear images for analysis without requiring surface contact.

AI summary
An application-analysable bodily fluid testing equipment (100, 200, 300) is provided. The application-analysable bodily fluid testing equipment comprises at least one testing region (109, 209, 309) sensitive to an indicator of a bodily condition in bodily fluid from which image data is capturable and analysable by an associated application on a device. The bodily fluid testing equipment further comprises a handling indicator (107, 207, 307) indicating an area of the equipment for a user to hold during the application of a bodily fluid to the at least one testing region, and during capture of the image data for analysis of the bodily fluid applied to the at least one testing region using the application on the device.
