Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for filling syringes with solutions are tedious and prone to human error, especially when dealing with various syringe sizes, as they require manual loading and result in inconsistent piston retraction.
Innovation Solution
A syringe cap designed for use with an automatic syringe filling apparatus that includes features for proper alignment and engagement with the apparatus, allowing for automatic syringe handling, decapping, and filling, ensuring consistent piston retraction across different syringe sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual loading method is used, then device complexity is reduced, but productivity is decreased and manufacturing precision is compromised
Solution Approach 1:
The syringe cap is designed with self-aligning features including a funnel-shaped reception area and engagement features that automatically guide the cap onto the syringe outlet port without requiring manual positioning or complex alignment mechanisms. The cap's geometry itself performs the alignment function, eliminating the need for complex positioning devices in the apparatus.
Solution Approach 2:
The syringe cap design incorporates multiple functions: it protects the needleless luer-style outlet port, provides automatic alignment through its funnel-shaped reception area, engages with the automatic filling apparatus via specific engagement features, and works with syringes of various sizes. This multi-functionality allows a single cap design to serve multiple purposes, reducing the need for specialized components for each function.
2Manufacturing precision
If manual loading method is used, then device complexity is reduced, but manufacturing precision is decreased
Solution Approach 1:
The cap's funnel-shaped reception area and geometric features automatically perform the alignment function, guiding the cap onto the syringe outlet port and ensuring proper positioning without requiring external alignment mechanisms. This self-aligning capability ensures consistent piston retraction across different syringe sizes without adding complex alignment devices to the apparatus.
Solution Approach 2:
The syringe cap features an asymmetric funnel-shaped reception area that is wider at the opening and tapers toward the outlet port. This asymmetric geometry provides guiding surfaces that naturally direct the cap into proper alignment during the loading process, ensuring consistent positioning without requiring symmetric or complex alignment mechanisms.
3Productivity
If automatic filling apparatus is used, then productivity is improved, but device complexity increases
Solution Approach 1:
The cap design incorporates self-aligning features including a funnel-shaped reception area and specific engagement features that automatically guide the cap onto the syringe outlet port and engage with the handling mechanisms. This self-positioning capability reduces the complexity of the automatic handling mechanisms required, as the cap performs part of the alignment and engagement functions itself.
Solution Approach 2:
The syringe cap has different geometric features at different locations: a funnel-shaped reception area at the opening for alignment, engagement features at specific positions for interacting with handling mechanisms, and a connector portion for the syringe outlet port. These localized features enable the cap to interact with the automatic filling apparatus at specific points, simplifying the overall handling mechanism design.
4Adaptability or versatility
If syringe sizes are varied, then adaptability is improved, but manufacturing precision is worsened
Solution Approach 1:
The syringe cap design incorporates universal features that work with syringes of various sizes. The funnel-shaped reception area provides alignment guidance regardless of syringe dimensions, and the engagement features are positioned to accommodate different syringe geometries. This universal design allows the same cap to maintain accurate alignment and engagement across multiple syringe sizes without requiring size-specific variations.
Solution Approach 2:
The cap's geometric features, particularly the funnel-shaped reception area and engagement features, automatically adapt to different syringe sizes through self-alignment during the loading process. The cap's own geometry performs the alignment function, ensuring accurate positioning even when syringe dimensions vary, without requiring the apparatus to detect or adjust for specific syringe sizes.

AI summary
A syringe tip cap is provided for use with an automatic syringe loading apparatus. The cap includes a body having an exterior surface and an interior surface, and having a first end and an opposite second end. The first end is defined by at least one generally "V"-shaped ramp on each of two sides of the exterior surface.
