Testing Strip Holder With Elastic Auto-Ejection Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holding devices for testing strips require manual removal, posing a risk of infection to medical caregivers and have complex structures that are costly to produce and difficult to control.
Innovation Solution
A holding device with a simple structure comprising a first accommodation portion, a second accommodation portion, an elastic portion, and an actuating portion, where the elastic portion applies forces to both portions to facilitate the automatic ejection of the testing strip without manual contact, allowing for controlled ejection force and reduced cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If manual removal of testing strip is required, then device structure can be simple, but infection risk to medical caregivers increases
Solution Approach 1:
The testing strip ejection mechanism is designed to automatically eject the testing strip after use without requiring manual removal. The elastic portion stores energy and automatically propels the testing strip out of the holding device, making the system self-serving and eliminating the need for caregivers to manually contact the testing strip.
Solution Approach 2:
The harmful aspect of manual contact is eliminated by extracting the testing strip ejection function from manual operation. The device automatically extracts and ejects the testing strip using the elastic portion, separating the ejection function from human intervention and thereby reducing infection risk.
2Device complexity
If traditional holding device structure is used with spring surrounding rod, then ejection force can be controlled, but device complexity and cost increase
Solution Approach 1:
The holding device is segmented into distinct functional portions: a first accommodation portion for holding the testing strip, a second accommodation portion that moves, and an elastic portion connecting them. This segmentation allows each component to have a specific function while simplifying the overall structure compared to traditional designs where the spring surrounds the rod.
Solution Approach 2:
The device incorporates dynamic movement between the first and second accommodation portions. The elastic portion provides dynamic force storage and release, enabling controlled ejection without requiring the complex fixed-structure spring-rod arrangement. The space between portions expands and contracts dynamically during operation.
3Length of moving object
If accommodation body is driven in parallel to testing strip, then ejection direction is controlled, but ejection distance is constrained
Solution Approach 1:
The ejection mechanism transitions from one-dimensional parallel movement to two-dimensional movement. The second accommodation portion moves relative to the first accommodation portion in a direction that is not strictly parallel to the testing strip axis, allowing the testing strip to be ejected with greater distance and flexibility. The connecting part enables movement in multiple directions while maintaining control.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device enables safe, convenient, and infection-free removal of testing strips, providing a user-friendly and cost-effective solution for Point-of-Care Testing systems by eliminating the need for manual handling and simplifying the ejection mechanism.
Implementation Method 1
The elastic portion includes a first end applying force to the first accommodation portion and a second end applying force to the actuating portion

AI summary
A holding device comprises a first accommodation portion, a second accommodation portion, an elastic portion, and an actuating portion. The elastic portion includes a first end contacting the first accommodation portion and a second end contacting the actuating portion. The first accommodation portion includes at least one aperture. The second accommodation portion includes at least one connecting part, which passes through the aperture and connects with the actuating portion. When the actuating portion is pressed toward the first accommodation portion, a space between the first accommodation portion and the second accommodation portion expands.
