Solution Overview

Problem

Existing methods for cleaning and inspecting functional layers, such as those in fuel cells, are inefficient and require separate devices for each side of the layer, leading to increased complexity and cost.

Innovation Solution

A device comprising two pivotably mounted vacuum plates and a linearly reciprocating cleaning and inspection unit, allowing for simultaneous cleaning and inspection of both sides of a functional layer without the need for separate devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If separate devices are used for cleaning and inspecting each side of the functional layer, then cleaning and inspection can be performed on both sides, but device complexity and cost increase

Engineering Contradiction:
Improvecleaning and inspection capabilityVSAvoiddevice structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines two separate cleaning and inspection devices into a single integrated device. The first cleaning device and first inspection device are merged with a second cleaning device and second inspection device to form one unified system that can process both sides of the functional layer, thereby reducing device complexity and cost while maintaining full cleaning and inspection capability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated device is designed to perform multiple functions: it can clean the first side and second side of the functional layer, inspect both sides, and transfer the functional layer between processing positions. This multi-functional design eliminates the need for separate dedicated devices for each function.

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

2Device complexity

If a single device is used for cleaning and inspecting both sides of the functional layer, then device complexity is reduced, but the device must handle multiple functions simultaneously

Engineering Contradiction:
Improvedevice structureVSAvoidmulti-side processing capability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The integrated device is segmented into distinct functional modules: a first cleaning device for the first side, a first inspection device for the first side, a second cleaning device for the second side, and a second inspection device for the second side. This segmentation allows each module to specialize in its specific function while being part of a unified system that handles both sides of the functional layer.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The device utilizes spatial arrangement in different dimensions to accommodate multiple processing functions. The first and second cleaning/inspection devices are positioned to access opposite sides of the functional layer simultaneously or sequentially, enabling multi-side processing within a single device footprint.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Device complexity

If manual transfer between vacuum plates is used, then device complexity is reduced, but processing efficiency and productivity decrease

Engineering Contradiction:
Improvetransfer mechanismVSAvoidprocessing efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The vacuum plates are designed to automatically transfer the functional layer from one plate to another through coordinated vacuum control. The system self-manages the transfer process without requiring manual intervention, thereby maintaining simple device structure while significantly improving processing efficiency and productivity.

Inventive Principle:
Principle #25Self-service

4Device complexity

If the cleaning and inspection unit remains stationary, then device complexity is reduced, but the ability to clean and inspect different areas of the functional layer is limited

Engineering Contradiction:
Improvemovement mechanismVSAvoidcoverage area
Core Design Contradiction:
Device complexityVSArea of stationary object

Solution Approach 1:

The cleaning and inspection unit is designed to be movable along the length of the functional layer. This dynamic capability allows the unit to access and process different areas of the functional layer, increasing coverage area while adding only minimal mechanical movement components to the device.

Inventive Principle:
Principle #15Dynamics
