Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a complex test board structure is used to place test paper strips, then multiple tests can be performed simultaneously, but the mounting and cleaning processes become complicated and time-consuming
Solution Approach 1:
The test board is divided into multiple independent slots, each capable of holding a separate test paper strip. This segmentation allows multiple tests to be performed simultaneously while keeping each slot simple and independent, facilitating easy mounting and cleaning of individual components.
Solution Approach 2:
The test board is designed with universal slots that can accommodate different types of test paper strips. Each slot serves multiple functions: holding the test paper, guiding the test liquid flow, and providing a standardized interface for mounting and cleaning, thereby simplifying the overall operation.
2Ease of manufacture
If a simple test paper card design is used, then the structure is easier to manufacture, but the mounting becomes inconvenient and sealing is difficult to ensure
Solution Approach 1:
The test paper card is designed with a nested structure where the test paper strip is inserted into a holder that fits within the test board slot. This nesting approach maintains simplicity in manufacturing while ensuring secure mounting through the hierarchical fitting of components.
Solution Approach 2:
A holder or mounting mechanism acts as an intermediary between the simple test paper card and the test board. This intermediary component ensures proper positioning and sealing without complicating the test paper card design itself, thereby maintaining ease of manufacture while improving mounting convenience.
3Reliability
If no sealing indication mechanism is provided, then the structure remains simple, but the user cannot verify proper sealing which may lead to test inaccuracies
Solution Approach 1:
A sealing indication mechanism using color-changing material is incorporated into the test board or holder. When the lid is properly closed and sealed, the color changes to indicate correct sealing. This provides reliable visual feedback without adding complex mechanical verification systems.
Solution Approach 2:
The sealing indication mechanism is designed to automatically detect and indicate the sealing status without requiring user intervention or complex external systems. The mechanism self-activates when the lid is closed, providing immediate verification of proper sealing through simple visual or tactile feedback.
