Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If data compression technique is used to transfer image data, then transmission bandwidth and power consumption are reduced, but complex images such as two-dimensional bar codes cannot be restored
Solution Approach 1:
The patent implements dynamic mode switching between full image data transfer and feature value transfer based on the type of image being captured. The system automatically determines whether to transmit complete image data or compressed feature values, allowing it to adapt to different scenarios and resolve the contradiction between energy efficiency and restoration accuracy.
Solution Approach 2:
The system changes the parameter of data representation from full image data to extracted feature values based on the image type. By detecting whether an image contains simple or complex information, the system dynamically adjusts the data format being transmitted, enabling efficient compression for simple images while maintaining full data integrity for complex images that require accurate restoration.
2Reliability
If full image data is transferred, then complex images can be accurately restored, but transmission bandwidth and power consumption increase
Solution Approach 1:
The patent extracts only the necessary feature values from images for transmission. By identifying and extracting key features such as coordinate values, area values, aspect ratios, and other object characteristics, the system transmits only the essential information needed to represent the image content, significantly reducing data volume while maintaining restoration accuracy for the intended application.
Solution Approach 2:
The system transmits partial image information (feature values) rather than complete image data when appropriate. This partial action approach is sufficient for interactive system applications where full image restoration is not required, achieving energy efficiency while providing adequate functionality for the specific use case.
3Quantity of substance
If feature values are extracted and transferred, then data transmission amount is reduced, but images with complex picture information cannot be restored
Solution Approach 1:
The system incorporates feedback mechanisms that allow the receiving end to determine whether the transmitted feature values are sufficient for the intended application. Based on this feedback and the known characteristics of the image type, the system can determine whether to transmit additional data or if the current feature values are adequate, ensuring both data efficiency and restoration reliability.
4Adaptability or versatility
If automatic mode switching is implemented, then both data reduction and complex image processing capabilities are achieved, but device complexity increases
Solution Approach 1:
The system implements self-service through automatic mode switching based on image type detection. The detection device autonomously determines whether to transmit full image data or extracted feature values without requiring manual intervention or complex external control systems. This self-determining capability achieves operational flexibility while keeping the control architecture relatively simple.

AI summary
A detection device includes an image capture element, a control signal generator, and a processor. The image capture element is used for capturing an optical signal, and outputting an image signal. The control signal generator is used for generating a control signal. The processor selectively converts the image signal into an object feature or an image feature in response to the control signal. Such a detection device can appropriately convert an operation mode, so as to have both efficacies of reducing the amount of transferred data and processing complex image data.
