Solution Overview
Problem
There is a need for substrate holders that can simultaneously coat both sides of a substrate during galvanic metal deposition, ensuring uniform metal deposition while preventing the passage of treatment liquids, and allowing for easy attachment and detachment of substrates.
Innovation Solution
A substrate holder comprising two parts with inner metal and outer non-metallic components, featuring hanging elements for container connection, sealing elements to prevent liquid passage, fastening systems for secure attachment, and contact elements for uniform current distribution, ensuring both sides can be coated efficiently and uniformly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a substrate holder is designed to coat both sides of a substrate simultaneously, then productivity is improved, but device complexity increases due to the need for multiple sealing elements and contact elements
Solution Approach 1:
The substrate holder is divided into two separate substrate holder parts, each capable of holding and coating one side of the substrate. This segmentation allows simultaneous processing of both sides while keeping each individual holder part relatively simple in structure, resolving the contradiction between productivity improvement and device complexity increase.
2Reliability
If sealing elements are added to prevent liquid passage, then reliability is improved, but device complexity increases
Solution Approach 1:
The sealing function is merged into the substrate holder parts themselves through integrated sealing elements, rather than being a separate additional component. This integration ensures reliable prevention of treatment liquid passage while minimizing the increase in overall device complexity by combining multiple functions into unified structures.
3Ease of operation
If a fastening system is implemented for automatic attachment, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The fastening system is designed to enable automatic or semi-automatic attachment and detachment of substrates without requiring complex manual operations. The system serves itself by providing intuitive alignment and securing mechanisms that reduce the skill level and time required for operation, improving ease of use while keeping the added complexity manageable.
4Manufacturing precision
If contact elements are distributed for uniform current flow, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
Contact elements are strategically distributed at specific locations on the substrate holder parts to ensure uniform current flow and metal deposition across the substrate surface. This localized placement of contact elements achieves high manufacturing precision for deposition uniformity while avoiding the need for complex uniform distributions across the entire holder structure.
