Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional glass syringes are integrated with medical devices using traditional adapter modifications, then the syringes can be connected to medical devices, but the integration becomes complex and requires costly one-off adapter modifications
Solution Approach 1:
The assembly element serves multiple functions: it acts as a securing mechanism, a positioning reference, and an interface component simultaneously. This universal component enables different glass syringe types to be integrated with various medical devices without requiring device-specific adapter modifications, thus reducing integration complexity while maintaining versatility
Solution Approach 2:
The assembly element acts as an intermediary component between the glass syringe and the medical device. It provides a standardized interface that mediates the connection, eliminating the need for complex one-off adapter modifications while maintaining compatibility across different syringe and device combinations
2Ease of manufacture
If the assembly element is secured on the rear flange of the glass syringe, then it can be attached to the syringe, but there is risk of over-stressing the glass syringe which often causes the glass to break
Solution Approach 1:
The securing means is designed with localized stress distribution features that concentrate attachment forces on specific reinforced areas of the glass syringe rather than distributing them across the entire flange. This local quality approach allows easy attachment while preventing widespread stress that could cause breakage
Solution Approach 2:
The assembly element incorporates cushioning or stress-absorbing features that are built into the design before assembly. These features preemptively absorb excessive stresses during attachment and operation, preventing glass breakage while maintaining ease of manufacture through standardized attachment procedures
3Ease of manufacture
If the assembly element is secured without a defined reference point, then it can be attached to the syringe, but the needle insertion depth becomes inaccurate
Solution Approach 1:
The assembly element includes a pre-defined reference point with standardized dimensions and positioning features that are built into the component during manufacturing. This preliminary action establishes precise needle insertion depth criteria before the actual assembly process, allowing simple attachment procedures to achieve precise results without requiring complex adjustment or measurement steps during assembly
