Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coating apparatuses fail to apply coating solutions in various patterns while changing the coating width and position on the surface of a coating object, leading to increased costs and operational complexity due to the need for multiple suppliers with different guide recess shapes.
Innovation Solution
A coating apparatus with a coating width adjuster and an intersection direction mover, which adjusts the width of the coating solution application and moves the nozzle and object in intersecting directions, allowing for varied patterns by using a rotatable guide recess or adjustable slit width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple coating solution suppliers with different guide recess shapes are prepared to apply coating solution in various patterns, then various patterns can be achieved, but costs increase and work of exchanging suppliers becomes significantly troublesome
Solution Approach 1:
The coating solution supplier is designed with a rotatable guide recess that can be positioned at different angles, allowing a single supplier to perform multiple functions of creating different coating patterns. The guide recess can be rotated to different angular positions to achieve various coating widths and positions, eliminating the need for multiple specialized suppliers.
Solution Approach 2:
The guide recess is made rotatable rather than fixed, allowing dynamic adjustment of the coating pattern during the coating process. This rotational capability enables the same supplier to adapt to different coating requirements by changing the angular position of the guide recess, transforming a static single-function component into a dynamic multi-function component.
2Adaptability or versatility
If the coating nozzle and coating object are moved relative to each other in the coating direction only, then the coating solution can be applied in a rectangular pattern, but various patterns cannot be achieved while changing coating width and position
Solution Approach 1:
The guide recess is made rotatable to dynamically change the coating pattern during operation. This allows the coating width and position to be adjusted by rotating the guide recess to different angular positions, enabling various patterns to be achieved without changing the basic linear movement mechanism, thus maintaining ease of operation while increasing adaptability.
Solution Approach 2:
The invention adds rotational degree of freedom to the existing linear movement system. By rotating the guide recess around the coating direction axis, a new dimension of control is introduced that enables variation in coating width and position while maintaining the simple linear movement structure, thus achieving pattern variety without complicating the operation.
3Manufacturing precision
If a guide recess with a predetermined pattern shape is used to guide coating solution, then that specific pattern can be achieved, but changing to different patterns requires exchanging the entire coating solution supplier
Solution Approach 1:
The guide recess is made rotatable so that different coating patterns can be achieved by rotating to different angular positions rather than exchanging entire suppliers. This maintains the precise pattern formation capability of the fixed guide recess geometry while eliminating the time-consuming exchange process, as only rotation is needed to change patterns.
Solution Approach 2:
The guide recess is pre-designed with a specific geometry that can produce accurate coating patterns when positioned at different angles. This preliminary design allows the same physical structure to serve multiple pattern requirements, eliminating the need for multiple pre-fabricated suppliers and reducing exchange time to simple rotation operations.
