Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coating facilities face challenges with contamination, increased size, logistical effort, and high installation costs due to the separation of cleaning, coating, and curing steps, requiring complex and expensive transport systems and separate sections.
Innovation Solution
A modular coating facility design with separate work modules, each equipped with fresh air supply, extraction, and transport, connected via doors for seamless substrate flow, and controlled by a central unit, allowing for decentralized control components and reduced cabling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the coating facility is divided into separate sections for cleaning, coating, and curing steps, then contamination between process steps is prevented, but the facility size and device complexity increase significantly
Solution Approach 1:
The coating facility is divided into multiple independent work modules (cleaning module, coating module, curing module), each capable of performing specific process steps. These modules can be independently separated, transported, and assembled, preventing cross-contamination while reducing overall system complexity compared to a fully integrated facility.
Solution Approach 2:
The patent transitions from a traditional linear inline arrangement to a modular configuration where modules can be arranged in different spatial configurations (series, parallel, or mixed). This dimensional flexibility allows optimization of facility layout while maintaining process separation.
2Reliability
If separate sections are used for different process steps, then process steps do not adversely affect each other, but the facility requires complex transport systems and increases in size
Solution Approach 1:
The facility is segmented into compact work modules that can be independently positioned. Each module contains its own transport capability, eliminating the need for extensive centralized transport systems and reducing overall facility length.
Solution Approach 2:
Each work module is designed as a multi-functional unit that can perform multiple operations (cleaning, coating, curing) within a compact space, reducing the need for separate dedicated spaces for each function.
3Productivity
If a centralized transport device is used throughout the facility, then substrate transport is coordinated, but the transport device becomes complicated and expensive
Solution Approach 1:
The centralized transport device is replaced by distributed transport mechanisms within each work module. Each module has its own transport capability, simplifying the overall transport system while maintaining coordination through module-level control.
Solution Approach 2:
The patent introduces interface mechanisms (doors, transfer points) between work modules that act as intermediaries for substrate transfer. These simplified interface mechanisms replace the need for complex centralized transport while maintaining coordinated substrate flow.
4Adaptability or versatility
If sections are separated by doors and mechanisms, then individual sections can operate independently, but the sections become insufficiently separated and the system size increases
Solution Approach 1:
The facility is divided into completely separate work modules that can be physically disconnected and independently operated. Each module is self-contained with its own environment control, achieving true separation while maintaining compact dimensions.
Solution Approach 2:
The patent uses flexible sealing mechanisms (doors, curtains) that provide effective separation between modules without requiring large buffer spaces. These flexible barriers enable independent operation while minimizing the space required for separation.
