Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laminators face challenges in maintaining a tensioned state of the laminated substance during the lamination process, leading to issues like wrinkles or wavy lines due to fixed pressure and speed settings, which can result in inadequate sealing or deformation.
Innovation Solution
A preheating-free laminator design featuring a rubber feeding and pushing component with a lower linear speed than the rubber roller set, creating a static friction fit with the laminated substance and a sliding friction fit with the feeding component, ensuring the substance is kept in a tensioned state and preventing undesirable effects during lamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the laminated substance is directly inserted into the rubber roller set, then the operation is simple, but the substance cannot be maintained in a tensioned state, causing wrinkles or wavy lines
Solution Approach 1:
The feeding system is divided into two separate components: a rubber feeding component and a rubber roller set. The feeding component introduces the substance and maintains tension, while the roller set performs the lamination. This segmentation allows each component to have optimized functions, resolving the contradiction between simple operation and lamination quality.
Solution Approach 2:
The rubber feeding component acts as an intermediary between the substance introduction and the rubber roller set. It maintains the substance in a tensioned state through coordinated pushing action, preventing wrinkles while enabling smooth operation. The intermediary component bridges the gap between simple feeding and quality lamination.
2Device complexity
If the pressure and speed are fixed, then the device structure is simple, but the plastic seal quality deteriorates when temperature is not optimal
Solution Approach 1:
The system implements dynamic speed control where the rubber feeding component and rubber roller set operate at different linear speeds. The feeding component moves slower to maintain tension, while the roller set moves faster for effective lamination. This dynamic speed differentiation improves seal quality without significantly complicating the device structure.
3Device complexity
If the rubber feeding and pushing component has the same linear speed as the rubber roller set, then the structure is simple, but the substance cannot be maintained in a tensioned state
Solution Approach 1:
The system changes the speed parameter of the rubber feeding component relative to the rubber roller set. By operating at a lower linear speed, the feeding component creates the necessary tension in the substance. This parameter change is simple to implement and effectively maintains the tensioned state without complex structural modifications.
