Syringe Holder With Independent Second Activator Lever
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing syringe holders for motorized injection devices do not provide sufficient comfort, effort reduction, and ergonomic visibility, leading to suboptimal user experience, especially in applications requiring precise and low-effort operation.
Innovation Solution
A syringe holder with a second activation means, such as an actuation lever, allows independent control of the motorized injection device's predefined function, reducing user effort and improving ergonomics and visibility, while being simple, cost-effective, and robust.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a syringe holder is designed to mount on motorized injection device, then the device can eject product with motor system control, but the practitioner still needs to exert force manually on the piston depending on product viscosity
Solution Approach 1:
The patent replaces the manual mechanical piston pressing system with an automated motor-driven system. The motor system drives a first piston that automatically presses on the second piston, eliminating the need for manual force application by the practitioner regardless of product viscosity.
Solution Approach 2:
The motorized system performs the injection function autonomously once activated. The motor system automatically drives the piston to eject the product without requiring continuous manual intervention or force application from the practitioner, making the system self-sufficient for the injection process.
2Adaptability or versatility
If a syringe holder is designed with basic mounting function, then it can hold receptacles, but it does not provide optimal visibility and ergonomic handling
Solution Approach 1:
The syringe holder is divided into distinct functional segments: a mounting portion for attaching to the motorized device, a holding portion for securing the receptacle, and a positioning portion that optimizes visibility. This segmentation allows each part to be optimized for its specific function while maintaining overall versatility.
Solution Approach 2:
Different portions of the syringe holder are designed with different local characteristics. The positioning portion includes specific geometric features and surface properties that enhance visibility and ergonomic handling, while other portions maintain basic mounting and holding functions. This local optimization improves overall ease of operation without compromising versatility.
3Device complexity
If a single activation means is used for motorized injection device, then the control is simple, but the practitioner cannot optimize effort reduction for different applications
Solution Approach 1:
The activation system is designed to be dynamic and adaptable. The syringe holder includes a second activation means that can be engaged or disengaged based on the specific application requirements. This allows the system to transition between different activation modes, optimizing effort reduction for different injection scenarios while maintaining simple control through the lever mechanism.
Solution Approach 2:
The activation control is segmented into two independent means: a first activation means for basic control and a second activation means for optimized control. This segmentation allows the practitioner to select the appropriate activation mode based on the application, providing both simplicity and optimization without requiring a completely complex control system.

AI summary
A syringe holder for a motorized injection device, the syringe holder being adapted to receive a receptacle intended to contain a fluid or viscous substance, preferably a disposable refillable receptacle or a syringe, as well as being adapted to be mounted on the motorized injection device such that the motorized injection device enables a part or all of the fluid or viscous substance contained in said receptacle to be expelled. The syringe holder includes a first activator portion to control a predefined function of the motorized injection device. The syringe holder is distinguished in that it comprises a second activator portion to control said predefined function of the motorized injection device independently from the first activator portion.
