Solution Overview

Problem

Existing laminating devices require high energy for heating and cooling press pads, leading to increased energy consumption and maintenance costs due to wear and tear, and complicate the lamination process with uneven stacks.

Innovation Solution

A laminating tool with an embossing plate and carrier plate featuring a rib-shaped supporting structure surrounded by an outer wall, allowing for rapid heating and cooling through medium flow, which also compensates for stack unevenness with integrated pressure application.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If pressure pads are used to compensate for stack unevenness and apply uniform pressure, then lamination quality is improved, but energy consumption increases due to heating and cooling requirements

Engineering Contradiction:
Improvelamination qualityVSAvoidenergy consumption
Core Design Contradiction:
Manufacturing precisionVSUse of energy by stationary object

Solution Approach 1:

The patent combines the pressure application function and the temperature control function into a single integrated laminating tool. The tool includes a housing with heating elements and cooling channels built-in, eliminating the need for separate pressure pads. This integration reduces the number of components that require independent heating and cooling, thereby reducing overall energy consumption while maintaining lamination quality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The laminating tool is designed as a multi-functional device that simultaneously performs pressure application, heating, and cooling functions. The housing serves multiple purposes: structural support, pressure transmission, and thermal management through integrated channels. This multi-functionality eliminates the need for separate pressure pads and their associated thermal management systems, reducing energy consumption.

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

2Manufacturing precision

If pressure pads are used to apply uniform pressure, then lamination quality is improved, but maintenance costs increase due to wear and tear

Engineering Contradiction:
Improvelamination qualityVSAvoidmaintenance costs
Core Design Contradiction:
Manufacturing precisionVSEase of repair

Solution Approach 1:

The patent integrates the pressure application function directly into the laminating tool housing, eliminating separate pressure pads. The housing itself transmits pressure through its structure, which does not subject to wear in the same way soft pads do. This integration removes the wear-prone components, thereby reducing maintenance requirements and costs while maintaining consistent pressure application for quality lamination.

Inventive Principle:
Principle #5Merging (Combining)

3Temperature

If press plates and pressure pads are heated and cooled, then lamination process is enabled, but cycle time increases

Engineering Contradiction:
Improvetemperature controlVSAvoidcycle time
Core Design Contradiction:
TemperatureVSProductivity

Solution Approach 1:

The patent combines heating and cooling channels within the same laminating tool housing, allowing for rapid thermal response. The integrated design reduces thermal mass compared to separate press plates and pads, enabling faster heating and cooling cycles. This reduces the overall cycle time while maintaining the necessary temperature control for the lamination process.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The laminating tool incorporates separate heating channels and cooling channels that can operate independently or in sequence. This segmentation allows for optimized thermal management where heating and cooling can be targeted to specific regions or activated at different times, reducing unnecessary thermal processing and thereby reducing cycle time.

Inventive Principle:
Principle #1Segmentation

4Force

If multiple components (press plates and pressure pads) are used, then pressure application is effective, but device complexity increases

Engineering Contradiction:
Improvepressure applicationVSAvoidnumber of components
Core Design Contradiction:
ForceVSDevice complexity

Solution Approach 1:

The patent merges the press plate and pressure pad functions into a single integrated laminating tool. The housing structure itself serves as the pressure transmission element, eliminating the need for separate press plates and pressure pads. This reduces the number of components from three (press plate, pressure pad, and support structure) to one integrated unit, simplifying the device while maintaining effective pressure application through the housing's structural design.

Inventive Principle:
Principle #5Merging (Combining)
