Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single container is used in the sample analysis substrate, then the device complexity is reduced, but the ability to handle multiple liquids for complex reactions and improved detection accuracy is limited
Solution Approach 1:
The sample analysis substrate is divided into multiple independent container units (first container, second container, etc.), each capable of holding different liquids. This segmentation allows the system to handle multiple liquids simultaneously while maintaining a modular structure that doesn't excessively increase overall device complexity.
Solution Approach 2:
The cap structure serves multiple functions: it seals the containers, provides drive projections to move containers between holding and release positions, and integrates the control mechanism for multiple containers into a single component. This multi-functionality increases versatility without proportionally increasing device complexity.
2Measurement precision
If multiple containers are added to handle multiple liquids, then detection accuracy and reaction capability are improved, but the structure becomes more complex with multiple accommodating sections and drive mechanisms
Solution Approach 1:
Multiple container accommodating sections are integrated into a single substrate body, and the cap structure combines multiple drive projections into one unified component. This merging approach allows the system to handle multiple liquids for improved detection accuracy while consolidating structural elements to manage complexity.
Solution Approach 2:
The containers are designed to be automatically moved between holding and release positions by the drive projections on the cap when the cap is attached and rotated. This self-service mechanism reduces the need for additional external actuators or complex control systems, thereby improving detection capability without proportionally increasing structural complexity.
3Ease of operation
If containers are designed to be movable between holding and release positions, then the ability to control liquid release is improved, but the device requires additional accommodating sections and drive mechanisms increasing complexity
Solution Approach 1:
The cap acts as an intermediary mechanism that translates the simple action of cap attachment and rotation into the controlled movement of multiple containers between holding and release positions. This intermediary approach improves ease of operation by providing a single, intuitive control action while the internal drive projections handle the complexity of coordinating multiple container movements.

AI summary
A sample analysis substrate capable of holding a plurality of liquids. The sample analysis substrate has a microchannel structure for transferring a liquid through rotary motion, the sample analysis substrate including: a substrate body having a rotation axis; a first and a second container holding a first and a second liquid therein; a first and a second accommodating section accommodating the first and the second container; and a cap having a first and second projection and movably supported on the substrate body. As the cap moves, the first drive projection and the second drive projection move the first container and the second container with staggered timing, thereby releasing the first and the second liquid accommodated therein.
