Arc-Guided Nozzle Unit for Coating Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coating apparatuses face challenges in accurately applying liquid materials when the direction of the surface to be coated changes, leading to nozzle tip deviation and improper application.
Innovation Solution
A coating apparatus featuring a nozzle unit with a directional nozzle that moves along an arc-shaped guide portion, supported by a mechanism allowing it to maintain position and rotate, ensuring consistent discharge direction and preventing nozzle damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the nozzle unit is rotated to change the direction of the nozzle tip, then the discharge direction of the liquid material is changed, but the nozzle tip position deviates from the original position
Solution Approach 1:
The patent introduces a rotational degree of freedom around the nozzle tip point by using a spherical support structure. This allows the nozzle to change discharge direction in multiple dimensions while maintaining the tip position fixed, effectively adding a rotational dimension without affecting the positional dimension.
Solution Approach 2:
The support portion acts as an intermediary mechanism between the nozzle unit and the positioning system. It provides a spherical guide portion that enables rotational movement while maintaining positional stability, mediating between the need for directional change and position precision.
2Ease of operation
If the nozzle unit is rotated to face the surface to be coated, then the coating direction is adjusted, but additional control is required to maintain nozzle tip position
Solution Approach 1:
The spherical support structure provides self-guiding rotational movement. The nozzle unit can rotate freely within the spherical guide portion without requiring external control mechanisms for position maintenance, allowing the system to self-adjust orientation while maintaining tip position.
Solution Approach 2:
The support portion allows dynamic rotational adjustment of the nozzle orientation while maintaining a fixed tip position. This dynamic capability enables easy orientation control without adding complex positioning control mechanisms.
