Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a triplex laminating machine is used to complete lamination of three layers per time, then production efficiency is greatly improved, but the machine cannot accommodate four-layer laminating structures
Solution Approach 1:
The laminating machine is designed with multiple unwinding units (first, second, third, fourth unwinding units) and multiple coating units (first, second, third coating units) that can be configured in different combinations. The machine can operate in triplex mode for three-layer lamination or expand to four-layer lamination by utilizing the additional unwinding and coating units, making it universally applicable to both three-layer and four-layer laminating structures without requiring separate dedicated machines.
Solution Approach 2:
The machine incorporates adjustable web paths and reconfigurable coating arrangements that can dynamically adapt to different lamination requirements. The feeding paths and coating positions can be modified to accommodate various laminating structures, allowing the machine to transition between different operational modes (triplex or four-layer) based on production needs.
2Reliability
If the operation mode and lamination process are designed for certain fixed types of laminating films, then the machine can achieve stable operation, but it cannot meet the requirements of specific coating arrangements and feeding paths for special webs
Solution Approach 1:
The machine is divided into multiple independent functional units: first and second coating units, third and fourth coating units, and corresponding unwinding units. Each unit can be independently controlled and configured. This segmentation allows different portions of the machine to be optimized for specific coating arrangements while maintaining overall stable operation through independent control of each segment.
Solution Approach 2:
Different coating units are positioned at different locations with different functional characteristics. The first and second coating units can be configured for specific coating arrangements while the third and fourth coating units provide additional flexibility. Each local unit can be optimized for its specific function while contributing to the overall versatility of the machine.
3Manufacturing precision
If the operation modes and lamination processes are fixed, then the machine is optimized for specific types of lamination processes, but it limits the machine to only specific types of lamination processes
Solution Approach 1:
The machine is designed as a multi-functional system that can perform multiple lamination processes within a single machine. By incorporating multiple unwinding units and coating units with reconfigurable web paths, the machine can accommodate various lamination processes (two-layer, three-layer, four-layer) and different coating arrangements, eliminating the need for multiple dedicated machines while maintaining process optimization.

AI summary
A variable solventless laminating machine based on different laminating structures, and a transformation method. The variable solventless laminating machine comprises four unit sets (1, 2, 3, 4) which are horizontally arranged and a high-position unwinding component the upper part of which is vertically arranged. Four unwinding units (5, 7, 8, 9), three coating units (10, 11, 12), two laminating units (13, 14), one winding unit (6), and a matching control system are provided in total. According to structural characteristics such as the type of a substrate and an order of functional layers of a product to be laminated, appropriate functional units, a feeding path and a control function are selected on the laminating machine, so that combination and matching of the corresponding unwinding units (5, 7, 8, 9), coating units (10, 11, 12), laminating unit (13, 14), tension control units (15, 16, 17, 18, 19, 20, 21, 22, 23) and selected units in a corresponding module in a control program are implemented, so that the machine is transformed into a matching laminating system adapted to a specific laminating structure, for implementing a corresponding laminating process. The laminating machine can be transformed into seven laminating machines having different processes according to types of laminating structures, can respectively meet production requirements of different two-layer, three-layer or four-layer laminating structures, and covers almost all common laminating structures.
