Apparel Patch Detecting Seminal Fluid via Color Change
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods lack effective means to detect seminal fluid on apparel, particularly for vulnerable individuals such as children and elderly adults, who are at risk of sexual abuse and often cannot communicate the abuse, necessitating a novel detection method to provide evidence and protection.
Innovation Solution
A patch-sized apparatus with a disposable housing incorporating a fluid channel containing a chemical solution, including 1-Naphthylphosphate (disodium salt) and prostate-specific antigen (PSA), which is removably attached to apparel to detect seminal fluid, using color indication to communicate the presence of seminal fluid to caregivers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If a patch-sized apparatus with chemical solution is attached to apparel, then seminal fluid detection capability is provided, but device complexity increases
Solution Approach 1:
The detection apparatus is segmented into a disposable housing containing the chemical solution and a reusable receiver, allowing the complex detection chemistry to be isolated in a replaceable component that can be easily attached to and removed from apparel
Solution Approach 2:
A receiver component serves as an intermediary between the chemical detection solution and the user, collecting and containing the chemical reaction products while providing a interface for visual observation of detection results
2Reliability
If a disposable housing with chemical solution is used, then detection reliability is improved, but manufacturing complexity increases
Solution Approach 1:
The housing containing the chemical solution is designed as a disposable component that is manufactured separately and attached to the reusable receiver, allowing the complex chemical formulation to be produced using standard manufacturing techniques and then discarded after a single use
Solution Approach 2:
The chemical solution is pre-loaded and sealed within the housing during manufacturing, with the detection chemistry prepared in advance and protected from contamination until the moment of use, ensuring consistent and reliable detection performance
3Ease of operation
If color indication is used to communicate detection results, then ease of operation is improved, but measurement precision may be reduced
Solution Approach 1:
The chemical solution contains indicators that undergo distinct color changes when they interact with seminal fluid, providing an immediate and easily observable detection result that does not require specialized training or equipment to interpret
Solution Approach 2:
The chemical solution is formulated as a composite containing multiple components including detection reagents, buffers, and color indicators that work together to provide both high specificity for seminal fluid detection and clear visual signal output
