Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual rotational alignment is required for syringe engagement with fluid injector, then secure connection is achieved, but procedure time and operational complexity increase
Solution Approach 1:
The syringe retaining member with tapered surface automatically orients the syringe to the correct rotational position during insertion into the fluid injector. The taper guides the syringe into proper alignment without requiring manual rotation or alignment efforts by the operator, thus reducing procedure time while maintaining secure connection through automatic engagement of the locking feature.
2Reliability
If manual rotation is required for syringe engagement with fluid injector, then proper alignment is achieved, but operational effort increases
Solution Approach 1:
The tapered surface on the syringe retaining member acts as a self-aligning mechanism that automatically orients the syringe to the correct rotational position during insertion. This eliminates the need for manual rotation efforts by the operator while ensuring accurate alignment and proper engagement of the locking feature with the fluid injector.
Solution Approach 2:
The tapered surface provides a curved, inclined guide that naturally directs the syringe into the correct rotational orientation as it is inserted into the fluid injector. This geometric feature reduces operational effort by allowing the syringe to self-align through its insertion motion rather than requiring manual rotational adjustment.
3Reliability
If rotational manipulation is required for syringe removal from fluid injector, then disengagement is achieved, but procedural complexity increases
Solution Approach 1:
The tapered surface on the syringe retaining member enables automatic disengagement during removal from the fluid injector. As the syringe is pulled out, the taper allows the locking feature to automatically release and the syringe to self-align in the removal direction, eliminating the need for manual rotation or complex disengagement procedures.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates quick and effortless loading and unloading of syringes by eliminating the need for rotational alignment, reducing procedural time and effort.
Implementation Method 1
The at least one syringe retaining member may have a surface tapered axially along an outer surface of the sidewall in a direction from the distal end toward the proximal end. The surface may be configured to rotationally guide the syringe into self-oriented alignment with the locking mechanism.

AI summary
A syringe including at least one retaining member protruding radially outward relative to an outer surface of a sidewall of a barrel of a syringe is described. The syringe retaining member is configured for interacting with a locking mechanism of a syringe port of a fluid injector to releasably retain the ring. Features of the syringe retaining member allow the syringe to be axially ejected from the syringe port upon rotation of the syringe. Other features of the syringe retaining member allow the syringe to engage the locking mechanism of the syringe port and rotationally guide the syringe into self-orienting alignment with the locking mechanism.
