Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional die coaters are inflexible and require new manufacturing when the coating position of an insulating liquid changes, leading to increased inconvenience and cost.

Innovation Solution

A die coater design with a first block, a second block, and a shim assembly that includes a detachable lip block with varying insulating liquid flow paths, allowing for the replacement of lip blocks to adjust to different coating positions without needing new manufacturing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the coating position of the insulating liquid is changed by moving the second slit, then the coating pattern is adjusted, but a new die coater must be manufactured, increasing cost and inconvenience

Engineering Contradiction:

Improvecoating position adjustmentVSAvoidmanufacturing cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The die coater is divided into a fixed first block and a detachable lip block. The lip block can be replaced to change the coating position without manufacturing a new entire die coater, thus reducing manufacturing cost while maintaining adaptability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The first block is designed with a universal structure that can accommodate multiple types of lip blocks with different flow path configurations. This allows a single first block to perform multiple coating patterns by simply changing the lip block, achieving versatility without repeated manufacturing.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Device complexity

If the insulating liquid flow path is fixed in the first block, then the structure is simple, but the coating position cannot be changed without new manufacturing

Engineering Contradiction:

Improveflow path structureVSAvoidcoating pattern flexibility

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The flow path structure is segmented into a fixed first block and a replaceable lip block. This segmentation allows the majority of the structure to remain simple and fixed, while only the lip block needs to be changed for different coating patterns, maintaining both simplicity and flexibility.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system transitions from a completely fixed flow path to a dynamic configuration where the lip block can be detached and replaced. This dynamic element allows the coating position to be adjusted without changing the overall device structure, balancing simplicity and adaptability.

Inventive Principle:

Principle #15Dynamics

AI summary

A die coater includes a first block having an insulating liquid inlet and a second block on the first block. A shim assembly is interposed between the first block and the second block and configured to form a first slit and a second slit separated from each other. The first block includes a fixing portion having a fixing flow path therein that is a transfer path for insulating liquid flowed in through the insulating liquid inlet, and also includes a lip block configured to be coupled to and detachable from the fixing portion and being a front end of the first block. The lip block has an insulating liquid flow path that is connected to the fixing flow path, and is a transfer path for insulating liquid flowed in through the fixing flow path.
