Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Urine drug testing faces challenges with specimen adulteration, substitution, and leakage issues, which compromise test reliability and privacy, and existing devices lack tamper-proof features to prevent these issues.
Innovation Solution
A specimen collecting and testing apparatus with tamper-proof features, comprising a first chamber for specimen collection, a second chamber with puncturing means and holes for gravitational flow to test strips, and a third chamber for testing, all sealed by a lid with interlocking flanges to prevent adulteration and leakage, made from transparent materials for easy handling and confirmation testing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If direct monitoring of urine specimen collection is implemented to prevent adulteration and substitution, then specimen reliability is improved, but privacy rights are violated
Solution Approach 1:
The collection system is divided into separate functional components: a collection container with tamper-evident seal, a testing chamber with integrated test strips, and a lid with interlocking flanges. This segmentation allows the specimen to be collected and tested without continuous monitoring while maintaining reliability through physical design features that prevent adulteration and substitution.
Solution Approach 2:
The patent introduces an intermediary testing chamber that receives the specimen from the collection container. This intermediary structure provides a controlled environment for testing that eliminates the need for direct monitoring of the collection process, while the tamper-evident seal and interlocking flanges ensure specimen integrity throughout the process, thereby protecting privacy while maintaining reliability.
2Ease of operation
If conventional urine collection containers are used, then ease of operation is improved, but specimen adulteration and substitution cannot be prevented
Solution Approach 1:
The patent merges the collection container, testing chamber, and lid into a single integrated apparatus. The collection container is positioned within the testing chamber, and the lid with interlocking flanges seals both components together. This merging ensures that once the specimen is collected, it cannot be accessed or adulterated without compromising the sealed structure, thereby maintaining both ease of operation and specimen integrity.
Solution Approach 2:
The tamper-evident seal is applied to the collection container before specimen collection, and the interlocking flanges are designed into the lid structure in advance. These preliminary actions ensure that any attempt at adulteration or substitution is prevented before it can occur, while the overall design remains simple and easy to operate.
3Ease of operation
If the lid or cap is removed for confirmatory testing, then accessibility for testing is improved, but specimen spillage and contamination occur
Solution Approach 1:
The lid serves multiple functions: it seals the collection container during transport, provides access to the testing chamber for specimen analysis, and maintains specimen containment throughout the process. The interlocking flanges ensure that when the lid is removed for testing, the collection container remains sealed, preventing spillage and contamination while allowing necessary access for confirmatory testing.
Solution Approach 2:
The collection container is nested within the testing chamber, and both are sealed by the lid. This nested structure allows the lid to be removed for testing while the inner collection container remains intact and sealed, preventing specimen spillage and contamination while providing accessibility for testing procedures.
4Productivity
If vigorous shaking of the container occurs during transfer, then mixing of specimen is improved, but spillage and backflow occur
Solution Approach 1:
The patent incorporates a cushioning structure between the collection container and the lid that absorbs shock and prevents spillage during vigorous shaking or transport. This beforehand cushioning ensures that even if the container is shaken vigorously for mixing, the specimen remains contained without spilling or backflowing, thereby maintaining both mixing efficiency and specimen containment.
