Analytical Tape Production via Self-Adhesive Test Label Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing analytical tapes require complex handling and disposal of disposable test strips, making them inefficient for automated and large-scale use in portable test instruments.
Innovation Solution
A two-step process involving a premanufactured test label tape with a detection film and adhesive tape, where test fields are transferred onto a transport tape as self-adhesive labels, enabling continuous production without complex handling, using a roll-to-roll conveying device and labelling device for efficient placement and attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional individual test strips are used, then each test can be performed independently, but complex handling and disposal of disposable test strips is required
Solution Approach 1:
The analytical tape is divided into multiple independent test fields arranged sequentially along the tape length. Each test field can be independently activated and tested, while the entire tape is handled as a single continuous medium, eliminating the need for separate handling of individual disposable test strips
Solution Approach 2:
Multiple individual test strips are merged into a single continuous analytical tape structure. The test fields are integrated onto the transport tape in a sequential arrangement, allowing multiple tests to be performed simultaneously on one tape rather than handling separate disposable strips for each test
2Productivity
If disposable test strips are used, then simplicity of individual test is maintained, but separate handling and disposal is required for each test
Solution Approach 1:
The analytical tape enables continuous testing operation where multiple test fields are activated sequentially without interruption. The tape can be continuously fed through the testing device, and test fields are activated in a continuous manner, eliminating the stop-start nature of handling individual disposable strips
Solution Approach 2:
Multiple test fields are pre-positioned and prepared on the transport tape in advance during tape production. The test fields are spaced apart and ready for immediate activation, eliminating the need for time-consuming preparation and handling of individual test strips during the testing process
3Ease of manufacture
If test fields are transferred onto transport tape as self-adhesive labels, then continuous processing is enabled, but transfer precision must be maintained
Solution Approach 1:
The test fields are designed as self-adhesive labels that automatically attach to the transport tape through their own adhesive properties. The adhesive layer on the test field directly bonds to the transport tape surface, eliminating the need for complex external bonding mechanisms or precision alignment devices
Solution Approach 2:
The adhesive layer on the test field is designed to provide uniform bonding across the entire contact surface with the transport tape. The adhesive properties are optimized to ensure consistent attachment strength and positioning accuracy without requiring complex external bonding systems or precise mechanical alignment

AI summary
The invention concerns a process for producing an analytical tape for liquid samples in which a rollable transport tape is provided with test fields that are spaced apart in the direction of the tape for analyzing the liquid samples. A multilayered test label tape is prefabricated from at least a detection film and an adhesive tape and subsequently the test fields are transferred as self-adhesive test labels from the test label tape onto the transport tape.
