Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If fluorescent or magnetic labels are used in immunoassay test strips, then measurement precision is improved, but device complexity increases and ease of operation deteriorates due to requiring electronic readers
Solution Approach 1:
The patent creates a visual copy of the detected label signals by generating an image that represents the spatial distribution and intensity of fluorescent or magnetic labels. This image copy allows users to interpret results visually without needing to understand electronic sensor data or use complex reading devices, thus maintaining high measurement precision while dramatically improving ease of operation.
Solution Approach 2:
The patent introduces an intermediary processing system that translates invisible or difficult-to-interpret label signals (fluorescent/magnetic) into a familiar visual format. This intermediary image generation process acts as a mediator between the sophisticated detection system and the end user, preserving the precision benefits of labeled assays while eliminating the complexity barrier.
2Measurement precision
If electronic readers are used to detect label signals, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent merges the detection system and the visualization system into a single integrated apparatus. The sensor that detects label signals is combined with the image generation and display components, eliminating the need for separate electronic readers and reducing overall device complexity while maintaining measurement precision.
Solution Approach 2:
Instead of requiring separate complex electronic reading devices, the patent creates a visual copy of the signal data directly within the test strip system itself. The sensor data is transformed into an image that can be viewed directly, eliminating the need for additional complex equipment.
3Productivity
If binary or quantitative results are provided without visual representation, then productivity is improved, but loss of information increases
Solution Approach 1:
The patent adds a visual dimension to the test results by generating images that display the spatial distribution and intensity of label signals. This transforms one-dimensional quantitative data into two-dimensional visual information, allowing users to quickly assess results at a glance while retaining all the detailed information about signal location and strength, thus eliminating information loss without sacrificing productivity.
