Syringe Holding Structure with Rotating Flange Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing syringe holding structures struggle to easily mount syringes with different flange shapes, as they often require complex mechanisms or special configurations for fixation.
Innovation Solution
A syringe holding structure featuring an adapter case with a cylindrical portion and a syringe holding member that includes a flange-receiving groove and locking mechanism, allowing for easy mounting by inserting the flange into the groove and rotating it by a predetermined angle, with ribs and vertical grooves to secure the syringe in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mechanism with hooks and notches is used to fix the syringe flange, then the fixation is secure, but syringes without notches cannot be mounted
Solution Approach 1:
The flange-receiving groove is designed with a universal structure that can accommodate different flange shapes (with or without notches). The groove includes engagement protrusions that can interact with various flange configurations, making the holding mechanism compatible with multiple syringe types while maintaining secure fixation through the same basic mechanism.
Solution Approach 2:
The adapter case serves as an intermediary component between the syringe flange and the holding mechanism. It provides a standardized interface that translates different flange shapes into a common mounting format, allowing various syringe types to be secured by the same holding structure without requiring the flange itself to have specific features like notches.
2Reliability
If a complex mechanism with multiple steps is used to mount the syringe, then the fixation is secure, but the mounting process becomes complicated
Solution Approach 1:
The flange-receiving groove is pre-configured with engagement protrusions and locking features that automatically engage with the syringe flange during insertion. The rotation mechanism is designed so that a single rotational motion simultaneously achieves both positioning and locking, eliminating the need for multiple separate fixation steps.
Solution Approach 2:
The holding mechanism uses a dynamic locking system where the flange-receiving groove transitions from an open state during insertion to a locked state after rotation. The engagement protrusions are designed to flex or move during insertion, then lock into place upon rotation, providing secure fixation through a simple dynamic action rather than complex static structures.
3Ease of operation
If a simple rotation mechanism is used to fix the syringe, then the mounting is simple, but syringes with different flange shapes cannot be mounted
Solution Approach 1:
The flange-receiving groove incorporates multiple engagement features within a single rotational mechanism. The groove includes engagement protrusions that can interact with different flange geometries, allowing the same simple rotation action to securely mount various flange shapes without requiring separate mechanisms for each type.
Solution Approach 2:
The holding mechanism allows for parameter adjustments in the engagement geometry of the flange-receiving groove. The engagement protrusions are designed with variable interaction points that can accommodate different flange dimensions and shapes, enabling a single rotation mechanism to adapt to various syringe configurations while maintaining operational simplicity.

AI summary
A syringe holding structure includes an adapter case (40) for holding a small-diameter syringe, and a syringe holding member having a flange-receiving groove (77) for holing flange portion (46) of the case(40). The syringe holding structure further includes locking mechanism for fixing the flange portion (46) in the groove (77) when the flange portion is inserted into flange-receiving groove and then it is rotated by 90 degrees about its axis.
