Rotatable Diagnostic Reagent Container Tape Advancing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers for diagnostic reagents in tape form lack convenient and safe disposal of used sensors, inadequate protection against environmental moisture, and insufficient protection of reagent-sensing devices from wear and tear.
Innovation Solution
A rotatable container design with a body portion, lid portion, continuous tape, reagent-sensing device, and storage devices that advances the tape over the sensor during lid rotation, allowing for fresh reagent use and safe disposal of used tape, while protecting the sensor from environmental factors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing containers store reagents in tape form, then the reagent can be delivered and stored, but the used sensors cannot be conveniently or safely disposed of
Solution Approach 1:
The container is divided into separate compartments: a storage device for unused reagent tape and a disposal device for used sensors. This segmentation allows independent management of clean and contaminated materials, enabling safe and convenient disposal by simply removing the used portion from the disposal compartment.
Solution Approach 2:
The container acts as an intermediary system between the reagent source and the user/environment. By providing a structured disposal compartment, it mediates the disposal process, ensuring that used sensors are contained and disposed of safely without direct user handling of contaminated materials.
2Quantity of substance
If existing containers store reagents, then the reagent can be kept, but environmental moisture degrades the reagent
Solution Approach 1:
The container creates a protected environment for the reagent tape, isolating it from environmental moisture. The sealed container structure maintains a stable, dry atmosphere inside, preventing moisture degradation while preserving reagent availability for multiple uses.
Solution Approach 2:
The container uses sealed barriers (shells/films) to physically isolate the reagent from environmental moisture. This creates a protective boundary that allows the reagent to be stored and transported without degradation from external humidity.
3Quantity of substance
If existing containers hold reagent-sensing devices, then the devices can be stored, but they are not adequately protected from wear and tear
Solution Approach 1:
The container provides a protected environment that shields the reagent-sensing devices from environmental factors causing wear and tear. This controlled environment preserves sensor integrity and extends their usable life while maintaining availability.
4Quantity of substance
If existing containers store reagents, then the reagent can be kept, but the reagent-sensing device is not adequately protected from wear and tear
Solution Approach 1:
The container creates a protected environment that simultaneously preserves reagent availability and protects the sensing device from harmful factors including wear and tear. The sealed structure isolates both the reagent and sensor from environmental degradation.

AI summary
A container with a rotatable lid for reading and handling diagnostic reagents in tape form comprising a body portion, a lid portion, a continuous tape, a reagent-sensing device, and a storage device. The body portion includes an inner and outer surface. The lid portion is attached to the body portion and is adapted to rotate from a closed position to an open position. The continuous tape includes a diagnostic reagent. The reagent-sensing device is attached to either the body portion or the lid portion and adapted to read the diagnostic reagent. The storage device is attached to the body portion that is adapted to hold and dispense an unused portion of the continuous tape. During the rotation of the lid portion, the continuous tape is advanced from the first storage device and is extended over the reagent-sensing device.
