Protein Detection Granule with Color-Changing Indicator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pets often face difficulties in receiving timely and affordable health examinations due to the scarcity of pet hospitals and the need for effective indicators to detect protein content in urine, which is crucial for their health assessment.
Innovation Solution
A granule comprising modified silicone particles, a filler, an adhesive, a bacteriostatic agent, a deodorant, and a tetrabromophenol blue indicator is developed, which changes color when exposed to protein in pet urine, allowing for accurate protein content determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If pet owners take their pets to hospitals for health examinations, then accurate health assessment can be obtained, but the cost is high and hospitals are thinly distributed
Solution Approach 1:
The patent creates a simplified copy of the hospital-based health examination system by providing a portable detection granule that replicates the protein detection function. The granule contains the essential detection components (indicator, adhesive, filler) in a compact form that can be used at home, copying the core functionality of hospital laboratories without requiring the full hospital infrastructure.
Solution Approach 2:
The patent extracts the essential detection function from the complex hospital examination system. By isolating the protein detection capability into a standalone granule product, the invention separates the critical health assessment function from the expensive and geographically limited hospital setting, making it independently accessible to pet owners.
2Measurement precision
If traditional detection methods are used, then protein content can be detected, but the process is complex and requires professional equipment
Solution Approach 1:
The patent employs color change as the detection mechanism, where tetrabromophenol blue indicator changes color based on protein presence in urine. This visual indication method replaces complex instrumental detection with a simple colorimetric reaction that can be observed by non-professionals, maintaining accuracy while dramatically reducing system complexity.
Solution Approach 2:
The patent replaces mechanical and instrumental detection systems with a chemical reaction-based detection method. Instead of using sophisticated equipment to measure protein concentration, the invention uses a chemical indicator that automatically responds to protein presence through color change, substituting complex mechanical measurement with simple chemical signaling.
3Stability of the object's composition
If silicone particles are used as base material, then good chemical stability is achieved, but poor adhesion and aggregation issues occur
Solution Approach 1:
The patent creates a composite material system where silicone particles are combined with adhesive components (polymer adhesive, filler, indicator). This composite structure maintains the chemical stability of silicone while adding adhesion functionality through the adhesive matrix, resolving the contradiction between stability and bonding strength.
Solution Approach 2:
The patent introduces adhesive substances as intermediaries between silicone particles and the detection environment. The adhesive acts as a mediator that enables proper adhesion and dispersion of silicone particles without compromising their inherent chemical stability, allowing the particles to function effectively in the detection granule.
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
The granule provides a convenient and accurate method for pet owners to assess their pet's health status by quickly and persistently changing color in response to protein presence in urine, thereby aiding in timely health management.
Implementation Method 1
the granule will change color, and the protein content in the urine can be determined by whether the color changes and the color level
