Spring-Locked Cover for Rapid Diagnosis Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rapid diagnosis devices face issues with soiling of heating elements and accidental opening of cover elements, leading to inefficient heating, increased current consumption, and erroneous measurements due to environmental influences and temperature changes.
Innovation Solution
A rapid diagnosis device with a spring-loaded locking mechanism that secures the cover element in place once a test strip is inserted, preventing unintentional opening and protecting the internal environment from ambient disturbances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the cover element is made removable for cleaning the heating element, then the heating element can be cleaned, but the cover element may be accidentally opened during operation
Solution Approach 1:
The device determines the insertion status of the test strip in advance and only enables cover opening when a test strip is properly inserted. This preliminary check prevents accidental openings during critical measurement phases while still allowing access for cleaning when needed.
Solution Approach 2:
The control unit continuously monitors the insertion status of the test strip and provides feedback control for the locking mechanism. When no test strip is detected, the cover remains locked; when a test strip is detected, the cover can be opened. This feedback loop ensures the cover is only opened at appropriate times.
2Reliability
If the cover element is locked during operation, then environmental influences are blocked, but the cover cannot be opened for cleaning
Solution Approach 1:
The locking mechanism transitions from a static locked state to a dynamic state where opening is conditionally permitted. The control unit dynamically adjusts the locking status based on real-time detection of test strip insertion, enabling the system to adapt between protection mode and maintenance mode.
Solution Approach 2:
The system automatically determines when cleaning access is appropriate by detecting test strip insertion status. The control unit autonomously manages the locking mechanism without requiring manual intervention or user judgment, reducing the risk of accidental openings.
3Reliability
If the clip portion is deflected to lock the spring element, then the cover is secured, but the test strip insertion must trigger this locking action
Solution Approach 1:
The locking function is merged with the test strip insertion action. The same mechanical movement that inserts the test strip also deflects the clip portion to lock the cover. This combination eliminates the need for separate locking and opening actions, simplifying the user interface.
Solution Approach 2:
The control unit acts as an intermediary that coordinates between test strip detection and locking mechanism activation. It receives signals from the insertion detection and automatically triggers the locking action, bridging the gap between sensing and actuation.

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 solution effectively prevents erroneous measurements and maintains a stable internal environment by locking the cover element in place, ensuring consistent temperature control and protection from ambient light, thereby improving the reliability of test strip evaluations.
Implementation Method 1
The locking body is configured as a spring element (8) which comprises a clip portion (17)
Implementation Method 2
The arrangement of the heating element is required to bring the test strip to a specific temperature

AI summary
The invention relates to a rapid diagnosis device with a device housing, on which there is provided a push-in opening for a test strip. The test strip is evaluated inside the rapid diagnosis device. On the device housing there is formed a housing opening, which can be closed by a cover or flap element. The cover or flap element is assigned a locking body. The locking body is formed as a spring element which comprises a clip portion, which assumes a position locking the spring element when the test strip has been pushed into the push-in opening of the rapid diagnosis device.
