Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If barcode, QR code, or RFID methods are used for sample discrimination, then sample identification capability is improved, but visual discrimination efficiency and operator ease of use deteriorate when information amount increases
Solution Approach 1:
The patent segments sample information into two categories: identification information (stored in barcode/RFID) and classification information (displayed visually on the container). This segmentation allows operators to quickly visually distinguish samples by classification characteristics while machine systems can still access complete identification data, resolving the contradiction between information completeness and visual discrimination efficiency
Solution Approach 2:
The patent uses color coding on sample containers to visually represent classification information. Different colors or color patterns indicate different sample categories, conditions, or priorities. This color-based visual system enables operators to rapidly discriminate samples without reading text or scanning codes, significantly improving visual discrimination efficiency while maintaining accurate sample identification through the underlying barcode/RFID system
2Measurement precision
If more classification information is displayed on samples, then discrimination ability is improved, but device complexity and information overload increase
Solution Approach 1:
The patent divides information into identification data (handled by machine reading systems) and classification data (displayed visually). This segmentation prevents information overload on the container by only displaying essential classification markers, maintaining discrimination ability while reducing display complexity
Solution Approach 2:
Instead of displaying extensive text or complex symbols, the patent uses simple color codes to represent classification information. This approach maintains high discrimination ability through intuitive visual differentiation while minimizing the complexity of information presentation on the sample container
