Solution Overview
Problem
Existing analysis systems for detecting analytes in samples, particularly in diabetes diagnostics, require complex equipment and additional hardware for reading test element-specific information and positioning, leading to increased manufacturing costs, weight, and installation space.
Innovation Solution
An analysis system that uses a multifunctional detector to simultaneously detect analyte analysis zones and coding information, eliminating the need for separate sensors by incorporating test element-specific and position-specific information directly on the test elements, such as test strips or tapes, and utilizing a transfer device to position the test elements for detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate sensors and additional hardware are used to read test element-specific information and positioning, then measurement precision and reliability are improved, but device complexity, manufacturing cost, weight, and installation space increase
Solution Approach 1:
The patent combines the detector used for analyzing test elements with a separate sensor specifically designed to read test element-specific information and positioning data. This merging of detection functions into a unified system reduces device complexity while maintaining measurement precision, as the sensor and detector work together as an integrated unit rather than separate independent systems
Solution Approach 2:
The detector is designed to serve multiple functions: it detects analytes in test samples, reads test element-specific information, and determines positioning data. This multi-functionality eliminates the need for separate dedicated sensors for each function, thereby reducing device complexity, manufacturing cost, weight, and installation space while maintaining the required measurement precision
2Device complexity
If manual entry of test element-specific information is required, then device complexity is reduced, but loss of time and ease of operation deteriorate
Solution Approach 1:
The system enables automatic reading of test element-specific information through the sensor and detector combination, eliminating the need for manual entry by the patient or operator. The test elements themselves provide the information through machine-readable formats, allowing the system to self-configure and reducing both time loss and operational complexity
3Measurement precision
If separate positioning sensors are used, then positioning accuracy is improved, but device complexity and installation space increase
Solution Approach 1:
The positioning sensor functions are merged with the main detector, allowing the same detection unit to serve both analytical and positioning purposes. This integration reduces the total installation space required while maintaining positioning accuracy through the coordinated operation of the sensor-detector system

Function Achieved in This Case
This approach reduces equipment expenditure, installation space, and weight by integrating detection and coding functions into a single detector, enhancing the efficiency and accuracy of analyte detection while minimizing hardware requirements.
Implementation Method 1
The sample to be analyzed is applied to a test field (hereinafter also called analysis zone) of the test element and reacts in the test field, if necessary, with one or more reagents, which are usually selected specifically for the analyst to be detected. This reaction can be detected, for example optically, in particular photometrically
