Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electro-deposition methods for producing metallic components are inefficient and inflexible, requiring multiple baths and processes to deposit different metals, which is time-consuming and costly, and lack the ability to create components with varying properties and thicknesses in a single process.
Innovation Solution
A system and method for electrodepositing multiple electrolytes onto a substrate in a single deposition chamber or cradle, allowing for controlled deposition of different metals with varying thicknesses and properties by switching between electrolytes and adjusting current density, enabling the formation of complex 3D objects with tunable mechanical and thermal properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple electro-deposition baths are used to deposit different metals, then the desired multilayer component can be produced, but the process becomes time-consuming and costly due to moving work between baths and re-jigging anodes
Solution Approach 1:
The patent combines multiple electro-deposition baths into a single multi-compartment cell, allowing different metals to be deposited simultaneously in different compartments. This eliminates the need to move work between separate baths and perform re-jigging operations, directly resolving the technical contradiction by maintaining versatility while reducing process time.
Solution Approach 2:
The single electro-deposition cell is designed to perform multiple functions by accommodating different electrolyte compositions and deposition conditions in each compartment. This universal design allows the system to deposit various metals (e.g., copper, nickel, zinc, tin) simultaneously, achieving the versatility of multiple baths without the time loss of sequential processing.
2Productivity
If a single electrolyte contains salts of both metal ions for co-deposition, then multilayers can be formed by switching current density, but the deposition conditions are limited and adhesion may be compromised
Solution Approach 1:
The patent segments the electrolyte system into separate compartments, each containing a specific metal salt solution optimized for depositing a particular metal. This segmentation allows each compartment to maintain ideal deposition conditions for its specific metal, ensuring high adhesion quality while enabling efficient simultaneous deposition of multiple metals through the single cell design.
3Adaptability or versatility
If vacuum technologies are used for multilayer deposition, then dissimilar metals can be deposited, but the process is slow and expensive and requires line of sight from target to surface
Solution Approach 1:
The patent replaces the mechanical vacuum-based physical vapor deposition system with an electrochemical deposition system using ionic conduction in electrolyte solutions. This substitution enables deposition of dissimilar metals with superior speed and efficiency, as electro-deposition does not require vacuum conditions or line-of-sight geometry, directly resolving both the versatility and productivity concerns.
4Manufacturing precision
If masking and repositioning of anodes is performed at each step, then adhesion and finish can be provided, but the process becomes time-consuming
Solution Approach 1:
The patent employs preliminary action by pre-positioning multiple anodes in fixed locations within each compartment before the deposition process begins. The anodes are strategically arranged to provide optimal current distribution and surface finish quality for each metal deposition. This pre-configuration eliminates the need for time-consuming masking and repositioning operations during the process, while maintaining high manufacturing precision.
