Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated tooling is used to ensure syringe stability during testing, then image acquisition stability is improved, but device complexity and material constraints increase
Solution Approach 1:
The testing system divides the syringe into separable components (barrel, plunger, tip cap) that can be independently positioned and tested. The open frame structure segments the tooling into modular components rather than a single complex fixture, allowing flexible configuration for different testing scenarios while maintaining stability.
Solution Approach 2:
The testing apparatus is designed with universal features that can accommodate various syringe sizes and types. The adjustable holder and open frame structure allow the same tooling to perform multiple testing functions (x-ray imaging, video capture, mechanical testing) without requiring dedicated specialized fixtures for each test type.
2Measurement precision
If x-ray imaging is implemented during syringe testing, then internal component visualization is improved, but material selection constraints and device complexity increase
Solution Approach 1:
The testing system applies different material properties to different components based on their specific testing requirements. Non-metallic materials are used in regions requiring x-ray transparency, while metallic components are positioned where they won't interfere with imaging. This localized material selection allows the system to maintain versatility while enabling x-ray visualization where needed.
Solution Approach 2:
The system uses non-metallic tooling components and fixtures as intermediaries between the syringe and x-ray imaging system. These intermediary elements provide mechanical support and positioning while being transparent to x-ray radiation, allowing internal component visualization without requiring the entire testing apparatus to be x-ray compatible.
3Extent of automation
If remote operation capability is added to the testing apparatus, then operator safety and automation are improved, but device complexity increases
Solution Approach 1:
Manual mechanical operations are replaced with automated control systems that can be operated remotely. The testing apparatus incorporates motorized actuators and controlled movement mechanisms that substitute for manual manipulation, enabling remote operation while maintaining precise control over syringe positioning and testing parameters.

AI summary
Provided herein is a system for testing of a medical injection device. The system includes a testing apparatus for testing the device, with the testing apparatus including a frame having a bottom base, a top support spaced configured to secure a first portion of the injection device, and side track members. Guide rails extend vertically between the top support and the bottom base and a holder is movable along the guide rails and the side track members, with the holder securing a second portion of the injection device. An actuator is coupled to the frame and configured to move the holder along the guide rails, with movement of the holder causing a relative movement between the second and first portions of the injection device. An x-ray imaging system acquires x-ray images of the injection device, to capture the relative movement between the second and first portions of the device.
