Solution Overview

Problem

The existing chemical and electrolytic surface treatment systems face challenges in achieving uniform layer formation due to non-uniform current and fluid distribution, requiring frequent adjustments and component replacements when switching between different substrates, leading to increased time and costs.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the distribution body is exactly adjusted to correspond to a specific substrate shape and size, then uniform current and fluid distribution is achieved, but system adaption time and cost increase when substrate changes

Engineering Contradiction:
Improveuniform layer thicknessVSAvoidsystem adaption time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The distribution body is divided into multiple independently controllable distribution elements (first distribution element, second distribution element, etc.) that can be selectively activated or deactivated. This segmentation allows the system to adapt to different substrate shapes and sizes by controlling only the necessary elements, eliminating the need to reconfigure the entire distribution body when substrates change.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The distribution elements are equipped with independent control units that enable dynamic adjustment of their operational state (on/off). This dynamic control allows the system to optimize fluid and current distribution for each specific substrate configuration in real-time, maintaining uniform layer thickness while rapidly adapting to different substrate types without physical reconfiguration.
