Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for obtaining saliva samples from animals, such as pigs, often result in inadequate quantity and quality due to contamination, requiring complex laboratory processing and affecting veterinary examinations.
Innovation Solution
A collecting device with a filter and a receiving device, where saliva is absorbed and then separated within a flexible, compressible bag, allowing for filtration and containment of contaminants, enabling a simple, hygienic, and efficient saliva sample collection for direct veterinary examination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If saliva is collected using a receiving device by oral contact with the animal, then the saliva sample can be obtained, but the sample quantity and quality are inadequate due to contamination
Solution Approach 1:
The collecting device is divided into two distinct functional sections: a receiving device for oral contact with the animal to collect saliva, and a separate container for holding the filtered sample. This segmentation prevents cross-contamination between the collection process and the final sample, thereby improving sample quality while maintaining adequate quantity
Solution Approach 2:
The harmful contaminants are extracted and removed from the saliva sample through a filtration system. The filter physically separates contaminants from the saliva, extracting only the pure liquid sample into the container, thus resolving the contamination issue while preserving sufficient sample quantity for analysis
2Ease of operation
If the receiving device is handled at the sampling site, then the saliva can be collected, but the sample becomes further contaminated
Solution Approach 1:
The filtration function is merged directly into the collecting device structure, integrating the filter between the receiving device and the sample container. This combination allows the collection and filtration processes to occur together in a single integrated system, maintaining ease of operation while preventing contamination during handling
3Reliability
If complex processing is performed in the laboratory, then the contaminated sample can be analyzed, but the examination process becomes complicated
Solution Approach 1:
Filtration and sample preparation are performed in advance at the sampling site using the integrated collecting device with filter. By completing the filtration action beforehand, the sample arrives at the laboratory already prepared and contamination-free, eliminating the need for complex subsequent processing while ensuring reliable examination results
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 solution provides a filtered saliva sample that can be analyzed immediately without further processing, reducing contaminants and improving the quality of the sample for veterinary examination.
Implementation Method 1
saliva from the animal is taken up or absorbed by a receiving device
Implementation Method 2
the saliva or sample material is at least partially filtered, the filtered saliva or the filtered sample material forming a saliva sample
Implementation Method 3
the saliva or sample material absorbed by the receiving device is separated from the receiving device inside the collecting device, preferably by compressing or deforming the collecting device
