Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single liquid medicine container is used in existing high-pressure contrast injection devices, then the device structure is simple, but the injection efficiency is low due to interruption when container needs replacement
Solution Approach 1:
The injection system is segmented into multiple independent liquid medicine containers (first container, second container, third container) each with its own puncture device and control mechanism. This allows one container to be replaced or refilled while others continue injecting, maintaining continuous operation and improving injection efficiency without overwhelming complexity through modular design
Solution Approach 2:
Multiple liquid medicine containers are prepared in advance and connected to the injection line through puncture devices before injection begins. The system pre-configures multiple containers with controllers that can be activated sequentially or simultaneously, eliminating downtime during container replacement and improving overall productivity
2Reliability
If multiple liquid medicine containers are connected simultaneously to ensure continuous injection, then injection efficiency improves, but the control complexity and potential for errors increase
Solution Approach 1:
Each liquid medicine container is equipped with its own puncture device and controller that can independently regulate its own injection process. The containers self-manage their connection and disconnection from the injection line through automated control mechanisms, reducing the need for manual intervention and minimizing operational errors while ensuring reliable continuous injection
Solution Approach 2:
Controllers act as intermediary devices between the multiple liquid medicine containers and the central injection line. Each controller independently manages the flow from its associated container, providing a buffer that simplifies operation by isolating the complexity of multi-container management from the user while ensuring reliable continuous injection

AI summary
Disclosed are an injection line system and a high-pressure contrast injection device. The injection line system comprises an injection line, a first liquid suction line, a second liquid suction line, a plurality of first puncture devices connected in series, and a second puncture device. The injection line is provided with a first liquid inlet connector, a second liquid inlet connector and an infusion connector, the first liquid inlet connector and the second liquid inlet connector are both connected with the infusion connector, one end of the first liquid suction line is connected with the first liquid inlet connector, one end of the second liquid suction line is connected with the second liquid inlet connector, the first puncture device closest to the first liquid suction line is connected with the other end of the first liquid suction line, and the second puncture device is connected with the other end of the second liquid suction line. The plurality of first puncture devices are arranged in series, so that other first liquid medicine containers can be replaced while ensuring that at least one first liquid medicine container provides liquid medicine normally, thereby improving the injection efficiency of the liquid medicine.
