Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional rigid plastic plates with upper cover and bottom plate are used for detection kit, then structural strength and sealing are improved, but device size increases and production cost increases
Solution Approach 1:
The traditional single-piece rigid plastic structure is segmented into multiple functional layers: bottom card band, test strip, and sealing film band. Each layer performs a specific function, allowing the device to maintain structural integrity while reducing overall size and enabling flexible packaging configurations.
Solution Approach 2:
The invention replaces rigid plastic plates with flexible thin film structures. The bottom card band and sealing film band are made of flexible materials that can be heat-sealed to form compact, airtight cavities, dramatically reducing device volume while maintaining protective功能和密封性能.
2Strength
If traditional rigid plastic plates with upper cover and bottom plate are used for detection kit, then structural strength and sealing are improved, but production cost increases
Solution Approach 1:
The structure is divided into separate bands and layers that can be manufactured independently using cost-effective processes like extrusion and heat sealing, avoiding the high tooling costs of molded rigid plastic assemblies.
Solution Approach 2:
The invention changes the material state from rigid thermoplastics requiring injection molding to flexible films suitable for extrusion and heat sealing processes, which are more cost-effective and scalable for high-volume production.
3Reliability
If traditional detection kit structure is used, then sealing performance is improved, but plastic material usage increases harming environment
Solution Approach 1:
The invention uses thin flexible sealing film bands instead of thick rigid plastic covers. These thin films provide adequate sealing when heat-sealed to the bottom card band, dramatically reducing plastic material consumption while maintaining airtight protection for the test strips.
Solution Approach 2:
The invention embraces the disposable nature of detection kits by using inexpensive, biodegradable-friendly thin film materials that can be easily discarded after use, reducing environmental impact compared to durable rigid plastic components.
4Reliability
If traditional detection kit structure is used, then protection of test strip is improved, but automation of production decreases requiring manual assembly
Solution Approach 1:
The segmented structure of separate bands and layers can be assembled through simple sequential operations (placing test strips on bottom card band, sealing with film band) that are easily automated, unlike complex molded assemblies requiring manual alignment and fastening.
Solution Approach 2:
The invention replaces complex mechanical fastening systems (screws, clips, adhesives) with thermal sealing, which can be easily automated using heated rollers or sealing jaws, enabling high-speed automated production while maintaining reliable protection.
5Stability of the object's composition
If traditional detection kit structure is used, then test strip stability is improved, but labor cost increases due to manual assembly
Solution Approach 1:
The invention replaces manual mechanical assembly with automated thermal sealing processes. The heat sealing operation simultaneously secures multiple test strips in stable positions while protecting them, eliminating the need for multiple manual fastening steps and significantly reducing labor costs.

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.
