Problem
Existing disposable detection kits for diseases or physiological indicators are large in size, costly, environmentally unfriendly due to plastic use, and require manual assembly, leading to high labor costs and reduced product quality.
Innovation Solution
A manufacturing method involving automated production of multi-lined detection devices using a bottom card band, test strip, and sealing film band, with specific cutting and bonding processes to minimize plastic use and facilitate easy separation of individual units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid plastic plates are used for upper cover and bottom plate, then structural strength is improved, but device size increases and production cost increases
Solution Approach 1:
The patent replaces rigid plastic plates with flexible card board and thin sealing film. The card board provides sufficient structural support while being thin and flat, eliminating the need for bulky rigid plastic housing. The sealing film provides the necessary sealing function with minimal thickness, dramatically reducing the overall device volume while maintaining structural integrity.
2Reliability
If rigid plastic plates with large size are used, then packaging protection is improved, but storage and transportation costs increase
Solution Approach 1:
The flexible card board and sealing film structure provides adequate protection for the test strip while occupying minimal storage space. The thin-profile design eliminates the need for large rigid plastic housing, directly reducing storage and transportation volume while maintaining product protection through the coordinated structure of card board and sealing film.
3Ease of operation
If manual assembly process is used, then assembly flexibility is improved, but labor cost increases and product quality decreases
Solution Approach 1:
The patent divides the assembly into distinct functional layers (card board, test strip, sealing film) that can be independently manufactured and then quickly assembled. This segmentation enables both manual flexibility and automated processing, as each layer can be handled separately by picking, placing, and bonding operations without complex manual manipulation.
Solution Approach 2:
The patent replaces manual assembly operations with automated picking, placing, and bonding equipment. The simplified structure of card board plus sealing film is ideal for automated handling, allowing mechanical systems to perform assembly functions that were previously done manually, thereby increasing productivity while maintaining quality consistency.
4Manufacturing precision
If thermally injection molded plastic plates are used, then manufacturing precision is improved, but production cost increases
Solution Approach 1:
The patent replaces expensive thermally injection molded plastic plates with inexpensive card board and thin sealing film. These materials are much cheaper than molded plastics while still providing the necessary structural and sealing functions. The disposable nature of the detection device aligns with using low-cost materials that do not require expensive manufacturing processes.
5Strength
If large amount of plastic materials are used, then structural integrity is improved, but environmental friendliness deteriorates
Solution Approach 1:
The patent replaces large amounts of plastic materials with thin card board and sealing film, dramatically reducing plastic consumption. The card board provides structural integrity while being biodegradable or recyclable, and the thin sealing film uses minimal material to provide necessary sealing, thereby improving environmental friendliness while maintaining structural function.

AI summary
The present invention relates to a manufacturing method of a multi-lined detection device, in which test strips are sealed in airtight cavities between a sealing film and a bottom card to form at least two detection devices which are arranged side by side and connected two by two. Every two adjacent detection devices are connected by an incompletely disconnected cutting line that is easy to split. The present invention is cut and packaged using rectangular cutters including long serrated blades, thereby obtaining a multi-lined detection device which is small in size and uses little materials. In the present invention, it is easy to realize automated production, and the number of workers and labor intensity are reduced while greatly reducing production, packaging and transportation costs, so that the product is inexpensive.
