Solution Overview
Problem
Conventional electrode etching methods suffer from inaccuracies and damage to the electrode assembly due to vertical swelling and poor laser focusing, leading to suboptimal etching quality and potential damage from laser beams.
Innovation Solution
An electrode etching apparatus featuring a support roller with cylindrical segments coupled to a shaft for stable fixation, allowing precise laser irradiation between the segments, and incorporating suction holes for particle removal and adjustable segments to accommodate varying electrode assembly sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single roller structure is used to support the electrode assembly, then the structure is simple, but vertical swelling occurs causing etching position fluctuation and poor laser focusing
Solution Approach 1:
The support roller is divided into multiple cylindrical roller segments (first, second, third segments) that can be independently adjusted. This segmentation allows each segment to be positioned to match the specific width of the electrode assembly, preventing vertical swelling while maintaining structural complexity at an acceptable level.
Solution Approach 2:
The roller segments are designed to be movable and adjustable along the shaft, allowing dynamic adaptation to different electrode assembly widths. This dynamic adjustment capability ensures optimal support and prevents vertical swelling across various production scenarios.
2Stability of the object's composition
If the roller segments are fixed in position, then the structure is stable, but it cannot accommodate varying electrode assembly sizes
Solution Approach 1:
The roller segments can be moved along the shaft to adjust the overall width of the support roller, enabling adaptation to different electrode assembly sizes. Once positioned, they provide stable support during the etching process, balancing adjustability with operational stability.
Solution Approach 2:
By dividing the roller into separate segments that can be independently positioned, the system achieves both stability (each segment provides firm support) and versatility (segments can be reconfigured for different widths by adjusting their positions along the shaft).
