Holding Device for Testing Strip Automatic Ejection
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 and difficult to operate.
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 risk of infection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual removal of testing strip is used, then operation simplicity is improved, but infection risk to medical caregivers increases
Solution Approach 1:
The holding device automatically ejects the testing strip using an elastic portion that propels the strip out of the accommodation body without requiring manual contact. The device serves itself by incorporating the ejection mechanism within the holding device structure, eliminating the need for caregivers to manually remove potentially contaminated strips.
2Extent of automation
If complex ejection mechanism is used, then automatic ejection function is improved, but device complexity and cost increase
Solution Approach 1:
The holding device is divided into distinct functional segments: an accommodation body for holding the strip, an ejection body for propelling it, and an elastic portion providing the ejection force. This segmentation allows each component to perform its specific function with a simple structure, avoiding the need for a complex integrated mechanism while achieving automatic ejection.
Solution Approach 2:
The ejection mechanism uses a simple elastic portion that can be easily replaced or integrated into a disposable holding device. This approach reduces the complexity and cost of the ejection mechanism by using inexpensive elastic elements rather than complex mechanical systems, aligning with the trend of disposable medical testing devices.
3Reliability
If ejection force is increased, then ejection reliability is improved, but testing strip may get stuck on mechanism
Solution Approach 1:
The elastic portion is designed to provide a controlled ejection force that is sufficient to propel the testing strip out of the accommodation body but not so strong as to cause it to get stuck on the ejection mechanism. The physical parameters of the elastic element (such as spring constant, length, and material properties) are optimized to achieve the right balance between ejection reliability and smooth operation.

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.
