Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual assembly with machine sewing or rivet connection is used, then the assembly process is simple to implement, but the production efficiency is low and the production period is long
Solution Approach 1:
The assembly device is divided into multiple independent functional modules including locating mechanism, glue coating mechanism, feed mechanism, press-in mechanism, and pressure-keeping mechanism. Each module performs a specific function, allowing for streamlined automated operation while maintaining process simplicity through modular design.
Solution Approach 2:
The patent replaces traditional mechanical connection methods (machine sewing and rivet connection) with an automated glue-based assembly system. This substitution eliminates the need for complex sewing machines or rivet-setting equipment, achieving higher productivity through a simpler automated gluing process.
2Productivity
If manual assembly is used, then the device complexity is low, but the labor cost is high and production efficiency is low
Solution Approach 1:
The automated assembly device integrates multiple functions into a single system that can handle different assembly operations (locating, glue coating, feeding, pressing, and pressure-keeping) in sequence. This multi-functional automated system replaces multiple manual operations, significantly improving production efficiency while controlling overall system complexity.
Solution Approach 2:
The device enables automated self-service assembly where the system automatically performs all assembly operations without manual intervention. The manipulator automatically transfers components, the glue coating mechanism automatically applies adhesive, and the press-in mechanism automatically assembles parts, eliminating labor costs while achieving high productivity.
3Productivity
If rivet connection is used to fix the frame, then the connection strength is high, but the consumption of manpower and material resources is large
Solution Approach 1:
The patent extracts and eliminates the need for rivets as connection elements, using only glue for the assembly process. This extraction of the rivet component reduces material resource consumption while the automated glue application and pressing mechanisms maintain assembly efficiency and connection strength.
4Strength
If machine sewing process is used for zipper-type suitcase, then the assembly can be completed, but the production efficiency is greatly reduced and the mechanical strength is poor
Solution Approach 1:
The patent replaces the machine sewing process with an automated glue-based assembly system. This substitution eliminates the weak mechanical connection produced by sewing while achieving stronger bonds through adhesive, and simultaneously improves productivity by automating the entire assembly process without the limitations of sewing machine operations.

AI summary
A device for automatically assembling a shell and a middle frame by glue includes a locating mechanism of the middle frame, a glue coating mechanism, a feed mechanism, a press-in mechanism, and a pressure-keeping mechanism. Components to be assembled are transferred among the locating mechanism of the middle frame, the glue coating mechanism, the feed mechanism, the press-in mechanism, and the pressure-keeping mechanism through manipulators. An automatic assembly line is formed by the device to assemble various components of the case body, which considerably reduces the manual assembly cost, simplifies the complicated assembly process, effectively shortens the whole production period, and improves the production efficiency.
