Analyte Detection Apparatus With Acoustic Sealing Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing detection apparatuses for liquid samples are complex to operate, prone to leakage due to inconsistent lid sealing, and yield variable test results due to non-uniform timing in closing the lid, particularly for non-professional users.
Innovation Solution
A detection apparatus with a prompting device that uses an elastic and non-elastic element interaction to produce a sound when the lid is properly sealed, ensuring consistent sealing and providing a standardized timing for reading test results, featuring a simple and cost-effective design suitable for disposable plastic products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a closed cover body is added to the sample collection container, then the risk of technician contact with samples is reduced, but the device complexity increases
Solution Approach 1:
The patent combines the cover body with prompting elements (elastic piece, non-elastic piece) into a single integrated structure. The cover body itself serves dual purposes: sealing the container and providing the mechanical structure for sound generation when properly positioned, eliminating the need for separate safety devices
Solution Approach 2:
The cover body automatically provides safety functionality through its design. When the cover is properly placed on the container, the elastic and non-elastic pieces interact to produce a prompting sound, ensuring the user knows the container is sealed without requiring additional safety mechanisms or user knowledge
2Ease of operation
If additional structures are added to generate sound for prompting, then the operation guidance is improved, but the manufacturing cost and complexity increase
Solution Approach 1:
The elastic and non-elastic pieces serve multiple functions: they provide mechanical guidance for cover placement, generate the prompting sound, and ensure proper sealing. This multi-functionality eliminates the need for separate sound-generating components, reducing manufacturing complexity and cost
Solution Approach 2:
The patent uses simple, inexpensive materials (elastic piece and non-elastic piece) that can be easily molded into the cover body structure. These components are designed for single-use in disposable detection apparatus, minimizing manufacturing costs while providing effective operation guidance
3Reliability
If the lid is covered to seal the opening, then the leakage prevention is improved, but the sealing consistency varies with different operators
Solution Approach 1:
The elastic and non-elastic pieces provide immediate tactile and auditory feedback when the cover reaches the correct sealing position. The prompting sound confirms to the user that the lid is properly sealed, eliminating guesswork and ensuring consistent sealing regardless of operator skill level
Solution Approach 2:
The cover body is pre-designed with the elastic and non-elastic pieces positioned to automatically engage with the container opening at the correct sealing position. This preliminary configuration ensures that proper sealing is achieved through the mechanical design itself, not through operator knowledge or skill
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
