Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional biological sample collection methods require multiple steps, increasing the risk of contamination and human error, and are not user-friendly, especially for individuals with disabilities or limited knowledge of clinical procedures.
Innovation Solution
A single-unit device integrating a swab, sample container, and use-and-throw cartridge with a one-step mechanism for sample collection, extraction, and processing, featuring a one-way linear retraction mechanism to prevent contamination and simplify handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple steps are used for sample collection and processing, then the sample can be collected and processed, but the number of steps increases the risk of contamination and human error
Solution Approach 1:
The patent combines the swab, sample container, and processing cartridge into a single integrated device. The swab is inserted directly into the container which is then sealed and placed into the processing cartridge, eliminating multiple handling steps and reducing contamination risk through a unified workflow.
Solution Approach 2:
The device is pre-assembled with all necessary components (swab, container, cartridge) in a predetermined configuration. The container is pre-sealed and pre-positioned within the cartridge, so that when the user inserts the swab and activates the device, all subsequent processing steps occur automatically without requiring additional manual intervention.
2Ease of operation
If the swab is kept on any surface including tabletop, then the swab can be handled easily, but the chance of contamination increases
Solution Approach 1:
The swab is nested within the sample container, which is itself nested within the processing cartridge. This nested configuration allows the swab to be handled as part of the integrated assembly rather than separately, eliminating the need to place it on surfaces and reducing contamination risk while maintaining ease of operation through a single unified handling action.
3Device complexity
If separate components (swab and sample container) are used, then the device can be simplified, but the user must follow multiple steps precisely which complicates the process
Solution Approach 1:
By merging the swab, sample container, and processing cartridge into a single integrated device, the patent eliminates the need for users to follow multiple precise instructions for assembling and handling separate components. The unified design allows users to perform a single insertion and activation action, significantly simplifying the operational process.
4Productivity
If air drying or freezing is used for sample extraction, then the sample can be processed, but the chance for contamination or degeneration increases
Solution Approach 1:
The device performs sample extraction and processing automatically through its integrated mechanism. When the swab is inserted into the container and the device is activated, the system automatically transfers the sample from the swab to the processing cartridge without requiring manual air drying or freezing steps, thereby maintaining sample integrity while enabling efficient processing.
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 device reduces the number of steps to five or fewer, minimizes contamination risk, and allows users to perform sample collection and processing easily at home, without specialized knowledge or equipment, while being cost-effective and environmentally friendly.
Implementation Method 1
Samples, such as blood drops, buccal, nasopharyngeal, etc. can be collected with an absorbent material such as a swab
