Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If traditional separate collection and testing apparatuses are used, then testing can be performed, but the structure is complex and operation is difficult
Solution Approach 1:
The patent combines the sample collection component and testing apparatus into a single integrated device. The collection component includes an absorbing element that directly interfaces with the testing chamber, eliminating the need for separate collection containers and transfer steps. This merging of functions reduces structural complexity and simplifies operation by allowing users to collect and test samples in one continuous action.
2Quantity of substance
If traditional testing apparatuses are used, then samples can be tested, but a sufficient amount of samples is required
Solution Approach 1:
The absorbing element in the collection component is designed with specific local properties to maximize sample absorption efficiency. The material is selected and structured to absorb and concentrate analytes from minimal sample volumes, ensuring that even small samples contain sufficient analyte concentration for reliable testing. This local optimization of absorption properties allows reduced sample volume requirements while maintaining test reliability.
3Object-affected harmful factors
If traditional separate apparatuses are used, then collection and testing can be performed, but operator safety is compromised due to increased contact with samples
Solution Approach 1:
By integrating the collection and testing functions into a single apparatus, the system minimizes the number of times the operator must handle or contact the sample. The sample remains contained within the integrated device throughout the collection and testing process, reducing exposure opportunities and improving operator safety without significantly complicating the operation.
4Volume of moving object
If traditional apparatuses are used, then testing can be performed, but the structure is not compact and portable
Solution Approach 1:
The collection component is designed to nest within or directly interface with the testing apparatus. The absorbing element can be inserted into the testing chamber, and the collection component fits within the overall apparatus footprint. This nested arrangement allows the device to maintain a compact, portable form factor while integrating multiple functions, avoiding the need for separate bulky collection containers.
