Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a conventional laminating machine is used, then the lamination process is simple, but the glue layer becomes uneven due to surface roughness on base materials and defects in the laminating rubber roller

Engineering Contradiction:
Improveglue layer uniformityVSAvoidlaminating device structure
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The laminating device is segmented into multiple functional components: a first pressing rubber roller for initial lamination, a second pressing rubber roller for secondary lamination, a laminating cylinder for heat sealing, and a material pressing device for applying pressure to the base material. This segmentation allows each component to address specific issues with glue layer uniformity independently.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The material pressing device applies pressure to the base material before the lamination process to flatten surface roughness. The first pressing rubber roller performs an initial lamination pass to prepare the glue layer, and the second pressing rubber roller performs a secondary pass to ensure uniformity. These preliminary actions prevent defects from occurring during the main lamination process.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If a single laminating process is used, then the process is simple and fast, but it cannot meet various compounding requirements and cannot address different material defects

Engineering Contradiction:
Improvelaminating process flexibilityVSAvoidlaminating speed
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The laminating machine is designed with multi-functionality to handle different lamination requirements: forward single lamination, forward double lamination, and inverse single lamination. The first and second pressing rubber rollers can be configured in different arrangements to suit various base material conditions, making the machine adaptable to different materials and defect types without requiring multiple separate machines.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The machine allows dynamic adjustment of the lamination process parameters and configuration. The first and second pressing rubber rollers can be positioned and configured differently based on the specific requirements of the base material and the type of defect being addressed, enabling the system to adapt its behavior to different operational scenarios.

Inventive Principle:
Principle #15Dynamics

3Manufacturing precision

If the glue layer is applied without pressure control, then the application is fast, but surface roughness on base materials causes non-uniform glue distribution

Engineering Contradiction:
Improveglue layer uniformityVSAvoidpressure application time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The material pressing device applies pressure to the base material before the glue layer is applied. This preliminary action flattens the surface roughness in advance, ensuring that when the glue is applied and subsequent pressing occurs, the glue distributes uniformly across the surface without requiring extended pressure application time during the main lamination process.

Inventive Principle:
Principle #10Preliminary action
