Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional single-layer barcodes are used, then the system is simple and easy to implement, but the versatility and security for multipurpose applications are limited
Solution Approach 1:
The barcode system is segmented into multiple independent layers (first layer and second layer), each containing distinct data sets. The first layer contains base information accessible to all users, while the second layer contains additional information accessible only to authorized users. This segmentation allows the system to maintain simplicity for basic operations while providing enhanced versatility when needed.
Solution Approach 2:
The patent implements a nested structure where one barcode layer is superimposed on another, creating a multi-layered code. The second layer is positioned over the first layer such that both can be scanned simultaneously or sequentially. This nesting approach allows compact storage of multiple data sets within a single visual structure, enhancing versatility without significantly increasing the physical footprint or operational complexity.
2Reliability
If conventional single-layer barcodes are used, then the implementation is straightforward, but the security for accessing features and networks is insufficient
Solution Approach 1:
The barcode system is segmented into multiple independent layers (first layer and second layer), each containing distinct data sets. The first layer contains base information accessible to all users, while the second layer contains additional information accessible only to authorized users. This segmentation allows the system to maintain simplicity for basic operations while providing enhanced versatility when needed.
Solution Approach 2:
The system dynamically adjusts the level of access and information disclosure based on user authorization. Scanners can be configured to read only the first layer for general access, or both layers for authorized access. This dynamic behavior enhances security by ensuring that sensitive information in the second layer is only accessed when appropriate, while maintaining system simplicity through flexible scanning configurations.
3Adaptability or versatility
If multi-layer barcodes are implemented, then versatility and security are enhanced, but the device complexity increases
Solution Approach 1:
The system dynamically adjusts the level of access and information disclosure based on user authorization. Scanners can be configured to read only the first layer for general access, or both layers for authorized access. This dynamic behavior enhances security by ensuring that sensitive information in the second layer is only accessed when appropriate, while maintaining system simplicity through flexible scanning configurations.
Solution Approach 2:
The multi-layer barcode system is designed to be self-explanatory and self-regulating. The layered structure inherently guides the scanning process, with the scanner automatically detecting and reading the appropriate layers based on its configuration and the physical arrangement of the codes. This self-service approach reduces the need for complex operational procedures or user training, maintaining ease of use despite the enhanced functionality.
