Engineering Contradiction Analysis
1Manufacturing precision
If conventional rotary surface treating apparatuses are used to carry out plating treatment, then plating can be performed on fine treatment objects, but cumbersome and repetitive adjustments of operating parameters are required to achieve optimal plating quality
Solution Approach 1:
The control part stores multiple sets of operating parameters (rotation speed, energization current, plating time) that have been pre-optimized for different treatment objects. Before actual plating, the system performs preliminary test operations to automatically determine the optimal parameter set, eliminating the need for manual repetitive adjustments and enabling direct application of proven optimal settings.
Solution Approach 2:
The control part automatically determines optimal operating conditions by analyzing test operation results and selecting appropriate parameter sets from storage. This self-determination capability eliminates manual intervention in parameter adjustment, allowing the system to autonomously optimize plating quality based on the specific characteristics of each treatment object.
2Manufacturing precision
If manual adjustment of operating parameters is performed to optimize plating quality, then desired plating treatment can be achieved, but inefficiencies and increased waste occur during the plating process
Solution Approach 1:
The system performs preliminary test operations without full energization to evaluate how different liquid parameter settings affect treatment object behavior. Based on feedback from these tests, the control part automatically adjusts and selects optimal parameter sets before actual plating, ensuring minimal solution waste while achieving desired plating quality.
Solution Approach 2:
The control part stores and automatically selects from multiple pre-defined parameter sets covering different rotation speeds, energization currents, and plating times. By changing parameters based on treatment object characteristics determined through test operations, the system achieves optimal plating quality without manual trial-and-error that would consume excessive solution.
3Productivity
If multiple test operations are performed to determine optimal operating conditions, then efficient derivation of optimal parameters is achieved, but additional time is required for testing
Solution Approach 1:
The system performs preliminary test operations with partial or reduced energization rather than full plating conditions. This partial action allows rapid evaluation of parameter effectiveness without completing full plating cycles, significantly reducing test time while still providing sufficient data to determine optimal operating conditions for production plating.
