Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for applying decorative laminates to parts are inefficient due to inconsistent pressure, long curing times, high costs, and limitations in handling non-planar shapes and simultaneous application to multiple sides, with vacuum bag methods being ad-hoc and permanent tools being expensive and immobile.
Innovation Solution
A panel laminator system using flexible diaphragms supported by frames, with heating blankets to accelerate curing and a vacuum system for consistent pressure, allowing for efficient application to both sides of non-planar panels and reducing footprint and operational costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a vacuum bag is used to apply laminate, then the process is simple and low cost, but the pressure is inconsistent and curing time is long
Solution Approach 1:
The tool is segmented into two separate frames (first frame and second frame) with各自的 diaphragms, allowing independent control and consistent pressure application on both sides of the panel simultaneously
Solution Approach 2:
The system changes the pressure parameter by using a vacuum source to create negative pressure in the sealed enclosure, ensuring consistent pressure distribution across the laminate surface during curing
2Manufacturing precision
If permanent vacuum tools are used, then consistent pressure is achieved, but the cost is high and the tools are immobile
Solution Approach 1:
The tool incorporates movable frames that can be positioned and repositioned as needed, transforming a static permanent tool into a dynamic, relocatable system that maintains consistent pressure application
Solution Approach 2:
The system uses flexible diaphragms made of elastomer material that can conform to the panel surface while maintaining vacuum pressure, providing a cost-effective alternative to rigid permanent tools
3Use of energy by moving object
If room temperature curing is used, then energy consumption is low, but curing time is excessively long
Solution Approach 1:
The system changes the temperature parameter by introducing a heating blanket that can be activated to accelerate curing when needed, while allowing the option of room temperature curing to conserve energy
Solution Approach 2:
The heating blanket can be activated in periodic cycles during the curing process, providing thermal energy only when necessary to maintain productivity without continuous energy consumption
4Device complexity
If a single diaphragm is used, then the tool structure is simple, but it cannot apply laminate to both sides simultaneously
Solution Approach 1:
The tool is divided into two independent diaphragm systems (first diaphragm and second diaphragm) mounted on separate frames, enabling simultaneous laminate application to both sides of the panel while maintaining manageable structural complexity
Solution Approach 2:
The dual-diaphragm tool achieves multi-functionality by being capable of applying laminate to both sides of a panel simultaneously, increasing productivity without requiring multiple separate tools

AI summary
A panel laminator includes a first frame defining an outer boundary, the first frame operable to support a panel to be laminated and a first flexible diaphragm supported by the first frame to cover the outer boundary. The laminator includes a second frame sized and shaped to conform to the first frame along the outer boundary and a second flexible diaphragm supported by the second frame to match the outer boundary. The laminator includes a passage fluidly connected to the space between the first and second flexible diaphragms, with the passage configured to be coupled to a vacuum system in order to remove air from the space between the first and second flexible diaphragms during a lamination process. The first frame and the second frame are configured to rotate as a unit between a first, generally horizontal, orientation and a second, generally vertical, orientation.
