Multicomponent Syringe Coding for Orientation Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing devices lack mechanisms to ensure safe and correct orientation of multicomponent syringes or cartridges, leading to potential confusion and damage, which can result in unsafe or impossible dispensing operations, especially in critical applications like medical techniques.
Innovation Solution
The dispensing device incorporates coding elements on the syringe or cartridge and holder, allowing only one orientation of insertion, with the larger cross-section storage container being retained firmly, and features an ergonomically designed fastening flange with angled legs and visual coding to prevent incorrect usage and ensure secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If coding elements are added to the syringe and holder, then operating safety and correct orientation are improved, but device complexity increases
Solution Approach 1:
The patent applies asymmetry by providing coding elements on the syringe and holder that allow insertion only in a specific orientation. The holder has a specific geometric configuration that receives the syringe in a predetermined direction, preventing incorrect insertion while maintaining simplicity.
2Stability of the object's composition
If the storage container with larger cross-section is retained firmly, then dispensing stability is improved, but insertion complexity increases
Solution Approach 1:
The patent applies preliminary action by designing the holder and syringe coding elements to automatically guide the syringe into the correct orientation during insertion. The geometric coding ensures that the storage container with larger cross-section is positioned first and retained firmly, eliminating the need for manual adjustment or complex insertion maneuvers.
3Reliability
If coding elements are provided on syringe and holder, then prevention of incorrect syringe use is improved, but manufacturing complexity increases
Solution Approach 1:
The patent uses asymmetry in the coding elements design, which are simple geometric features that can be easily manufactured using conventional molding or machining processes. The asymmetric geometry provides clear directional guidance while remaining compatible with existing manufacturing capabilities.

AI summary
Disclosed is a dispensing device comprises a dispense mechanism and a multicomponent syringe. The fastening parts of the syringe are embodied such that the syringe can be inserted into a holder on the dispense mechanism on the plane of the reservoirs thereof and perpendicular to the plane formed by the handle and the triggering lever of the dispense mechanism. The fastening parts on the syringe and the insertion opening on the syringe holder of the dispense mechanism are provided with coding elements that ensure that the syringe is inserted in only one direction, thus preventing non-certified syringes from being dispensed by the dispense mechanism. In a preferred embodiment, ergonomically shaped syringe flanges can optionally be used for dispensing the syringe in an optimal manner by hand with the aid of a dispense mechanism.
