Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional microarray analysis systems are used, then analysis accuracy is maintained, but device complexity and cost increase, making them unsuitable for remote areas
Solution Approach 1:
The patent uses a camera to capture an image of the microarray and transmits this visual copy to a remote server for analysis. Instead of requiring complex local analysis equipment, the system creates a digital replica of the microarray state and processes it remotely, thereby maintaining analysis capability while eliminating the need for complex local hardware.
Solution Approach 2:
The patent extracts the analysis function from the local device and relocates it to a remote server. The local device only needs to capture and transmit images, while the computationally intensive analysis and calibration processes are performed remotely, separating the simple local function from the complex remote function.
2Adaptability or versatility
If traditional microarray analysis systems are deployed in remote areas, then local analysis capability is achieved, but cost and maintenance difficulty increase due to lack of electricity and laboratory resources
Solution Approach 1:
The system replaces expensive, specialized analysis equipment with a simple camera that can be found in most mobile devices. By capturing the microarray state as an image and analyzing it remotely, the system achieves remote area accessibility without requiring costly local laboratory infrastructure.
Solution Approach 2:
The patent introduces a camera and network communication as intermediaries between the microarray and the analysis system. This intermediary approach allows the microarray to be analyzed remotely through image transmission, eliminating the need for direct physical connection to complex analysis equipment and enabling deployment in resource-limited settings.
3Measurement precision
If environmental calibration is implemented, then measurement accuracy in varying conditions is improved, but processing complexity increases
Solution Approach 1:
The patent incorporates calibration elements directly onto the microarray substrate before the actual analysis. These pre-placed calibration features allow the remote system to automatically compensate for environmental variations in lighting, temperature, and humidity without requiring complex real-time adjustments or additional processing steps.
Solution Approach 2:
The calibration features on the microarray enable the system to self-correct for environmental conditions. The remote analysis software automatically uses these built-in calibration elements to normalize the image data, eliminating the need for manual calibration procedures or complex environmental sensing and adjustment mechanisms.
Data Source
AI summary
A remote microarray analysis system, method and apparatus for use in the remote analysis of a chemical compound microarray supported on a substrate is disclosed. Pixel image data is received from a remote location including image data that depicts (a) a calibration scale associated with the substrate and (b) the microarray. A transformation action of said pixel data corresponding to the calibration scale is determined and the received image data corresponding to at least the microarray is adjusted by applying the transformation action. The adjusted image of the microarray is compared with a database of stored microarray pixel data to extract information from said image.
