Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional immersion cartridges and jigs are used for electroless plating, then plating can be performed, but the configuration becomes complex and manufacturing costs increase
Solution Approach 1:
The cartridge is divided into an upper cartridge and a lower cartridge that can be separately manufactured and then assembled. The upper cartridge includes a holder with protrusion, while the lower cartridge includes an accommodating portion with recess, allowing independent fabrication and simplifying the overall manufacturing process while reducing costs.
Solution Approach 2:
The holder of the upper cartridge is inserted into the accommodating portion of the lower cartridge, creating a nested structure. This nesting design simplifies the overall cartridge configuration by integrating multiple functions into a compact assembly, reducing the number of separate components needed.
2Object-generated harmful factors
If Teflon is used for cartridge components, then plating is prevented on the assembly, but surface tension characteristics must be maintained
Solution Approach 1:
Teflon coating is applied selectively to specific surfaces of the cartridge components that are in contact with the plating solution, rather than the entire assembly. This localized treatment prevents plating on the cartridge surfaces while maintaining the required surface tension characteristics for proper plating solution flow and electrode formation.
Solution Approach 2:
Teflon acts as an intermediary material between the cartridge structure and the plating solution. Its low surface tension properties prevent the plating solution from adhering to the cartridge surfaces, thereby preventing unwanted plating deposition on the assembly while allowing the plating process to proceed normally on the electrodes.
3Productivity
If mass production is achieved through simple configuration, then productivity increases, but uniformity of electrode portion may be compromised
Solution Approach 1:
The holder and accommodating portion are designed with pre-determined geometric features (protrusion and recess) that automatically position the electrodes in precise, uniform orientations during the plating process. This preliminary structural design ensures consistent electrode placement and uniform plating thickness across all electrodes in mass production, eliminating the need for complex adjustment mechanisms.
Solution Approach 2:
The cartridge design with standardized holder and accommodating portion structures can accommodate multiple electrodes of the same type simultaneously. This universal design allows the same cartridge configuration to be used for producing multiple uniform electrodes in one operation, maintaining precision while enabling mass production through simple, repeatable processes.
