Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If independent activation elements and blocking elements are used for each operation slot, then code reading function is achieved, but device complexity and assembly complexity increase
Solution Approach 1:
The patent combines multiple independent activation elements and blocking elements into a single integrated activation element assembly. This assembly includes a first activation element, a second activation element, and a blocking element that are integrally formed as one piece, replacing the traditional design where each operation slot had separate components. This merging reduces the total number of components while maintaining the code reading function.
Solution Approach 2:
The integrated activation element assembly serves multiple functions simultaneously: it acts as both the activation element for initiating the reaction and the blocking element for preventing sample contamination. The first and second activation elements perform activation functions while the integrated blocking element performs protection functions, allowing one component structure to fulfill multiple roles that previously required separate parts.
2Object-affected harmful factors
If independent blocking elements are provided for each operation slot, then sample contamination is prevented, but assembly complexity increases
Solution Approach 1:
The patent integrates multiple blocking elements into a single blocking element structure that spans across multiple operation slots. Instead of providing separate blocking elements for each slot, one integrated blocking element is designed to protect multiple slots simultaneously, reducing the number of assembly steps while maintaining contamination prevention capability.
Solution Approach 2:
The blocking element is designed with distinct segments or regions that correspond to different operation slots, allowing it to function as multiple individual blocking elements while being manufactured and assembled as a single piece. This segmentation in function but unity in structure achieves both contamination protection and simplified assembly.
3Measurement precision
If multiple independent activation elements are used, then code reading accuracy is maintained, but material preparation burden increases
Solution Approach 1:
The patent combines multiple activation elements into a single integrated structure that includes first and second activation elements formed as one piece. This reduces the number of separate components that need to be prepared, stored, and assembled, thereby reducing material preparation burden while maintaining the functionality of multiple activation elements for accurate code reading.
