Plating Paddle With Segmented Square Bars For Uniform Stirring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surface treatment devices fail to uniformly stir surface treatment solutions, leading to non-uniform plating thickness and strength issues, as only the upper part of the paddle is mounted, resulting in inconsistent stirring and potential device weakness.
Innovation Solution
A surface treatment device with a paddle configured by integrally forming square bars at regular intervals along the object to be plated, featuring a curved surface in the cross-section, which is alternately positioned left and right, and optimized dimensions to ensure uniform stirring and improved strength, allowing for efficient and prolonged stirring without shielding the object.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If only the upper part of the paddle is mounted to the paddle shaft, then the device structure is simpler, but the stirring uniformity deteriorates and device strength is reduced
Solution Approach 1:
The paddle is divided into multiple square bars arranged in parallel, with each bar independently contributing to stirring. The square bars are segmented along the depth direction of the solution, allowing different regions to stir solution at different locations, achieving uniform stirring throughout the solution volume while maintaining structural simplicity.
Solution Approach 2:
The paddle structure transitions from a single-plane mounting to a three-dimensional arrangement where square bars are distributed both horizontally and vertically. The bars extend in the depth direction of the solution, creating a spatial stirring pattern that ensures uniform mixing throughout the entire solution volume rather than just at the surface.
2Device complexity
If only the upper part of the paddle is mounted to the paddle shaft, then the device structure is simpler, but the device strength deteriorates
Solution Approach 1:
The paddle is segmented into multiple square bars that are distributed along the depth direction. This segmentation allows the mounting structure to distribute mechanical loads across multiple attachment points rather than concentrating stress at a single upper mounting point, thereby improving overall paddle strength and durability.
3Manufacturing precision
If square bars are provided at regular intervals, then the stirring uniformity is improved, but the device complexity increases
Solution Approach 1:
The square bars are provided at regular intervals along the depth direction with identical dimensions and spacing. This homogeneous arrangement ensures that each bar contributes equally to stirring, creating uniform solution mixing throughout the treatment tank. The regular spacing pattern simplifies manufacturing and assembly while achieving the desired stirring uniformity.
4Manufacturing precision
If the curved surface is provided alternately facing left and right, then the stirring uniformity is improved, but the manufacturing complexity increases
Solution Approach 1:
The curved surfaces of adjacent square bars are alternately oriented to face opposite directions (left and right). This asymmetric arrangement creates a more effective stirring action by generating alternating flow patterns that enhance mixing uniformity. While the manufacturing process becomes slightly more complex, the alternating pattern can be achieved through standardized molding techniques and maintains overall manufacturing feasibility.
