Elastic Syringe Adapter for Universal Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional chemical liquid injectors require varying syringe mounting procedures based on syringe types, leading to potential user errors and improper syringe fixation, which can result in incorrect operation or syringe damage.
Innovation Solution
A chemical liquid injector design featuring a syringe adapter with elastically displaceable arm portions and a flange lock mechanism, allowing for a standardized mounting procedure across different syringe types, along with an adapter identifying system for the injection head to ensure correct syringe attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different mounting procedures are used for different syringe types, then each syringe type can be properly mounted, but user errors increase and operation reliability decreases
Solution Approach 1:
The injection head is designed with a universal adapter receiving structure that can accommodate different syringe types through a single standardized mounting procedure. The adapter mechanism provides universal compatibility while maintaining type-specific securing through elastic arm portions that adapt to various syringe diameters.
2Reliability
If a standardized mounting procedure is implemented for all syringe types, then user errors decrease and operation reliability improves, but the ability to properly secure different syringe types may be compromised
Solution Approach 1:
The adapter incorporates elastic arm portions with local adaptive properties that can be compressed to accommodate different syringe diameters. The arm portions maintain consistent engagement force across various syringe types while allowing local deformation to fit different sizes, achieving both standardization and adaptability.
3Reliability
If an adapter mechanism with elastic arm portions is used, then secure attachment of various syringe types is achieved, but device complexity increases
Solution Approach 1:
The elastic arm portions are designed to automatically engage and secure the syringe through their inherent elasticity. The arms compress during insertion and naturally return to their original position to secure the syringe, eliminating the need for manual adjustment or complex locking mechanisms. The system serves itself by using the elastic deformation to provide both the securing force and the adaptive capability.
