Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for manufacturing electroformed components are inefficient as they require separate manufacturing steps for each type of component, leading to poor accuracy and increased complexity when multiple types of components with different shapes need to be manufactured, especially those that are partially in close contact or moving relative to each other.
Innovation Solution
A method involving the sequential formation of electroformed components using photoresist layers and electroforming, with planarization and separation techniques to enable the concurrent manufacturing of multiple types of components with different shapes, including those that are partially in contact or moving relative to each other, by using a conductive layer as an electrode and applying a film for separation to facilitate accurate and efficient production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple types of electroformed components are manufactured using conventional separate manufacturing steps, then each component can be produced, but manufacturing efficiency is poor and production time increases
Solution Approach 1:
The patent merges the manufacturing process of multiple different electroformed components into a single integrated electroforming step. Different components are formed simultaneously on the conductive substrate using a single electroforming bath, eliminating the need for separate manufacturing steps for each component type. This directly resolves the contradiction by improving productivity through process consolidation while reducing total production time.
Solution Approach 2:
The conductive substrate serves as a universal platform that can simultaneously support the formation of various types of electroformed components with different shapes and functions. The electroforming process itself becomes a multi-functional technique capable of producing diverse components in one operation, thereby improving manufacturing efficiency and reducing time loss.
2Ease of manufacture
If separate manufacturing steps are used for different electroformed components, then each component can be produced, but manufacturing complexity increases
Solution Approach 1:
By combining multiple component manufacturing operations into a single electroforming step, the patent reduces the number of separate manufacturing steps required. This simplification directly addresses the contradiction by making the overall manufacturing process easier to execute while reducing the complexity associated with coordinating multiple separate processes.
3Manufacturing precision
If different manufacturing steps are used for components that are to abut each other, then components can be produced, but manufacturing accuracy in abutting portions cannot be ensured
Solution Approach 1:
The patent forms multiple components including those intended to abut each other in a single electroforming operation. This ensures that all components share the same manufacturing reference frame and process conditions, guaranteeing high precision at abutting interfaces. Simultaneously, the electroforming process can accommodate various component shapes and configurations, thus maintaining versatility while achieving superior abutment accuracy.
Solution Approach 2:
The electroforming process allows for local variation in component geometry and material properties while maintaining uniform manufacturing conditions across all components. This enables precise control of abutting surfaces with the required accuracy while still producing components with diverse shapes and functions as needed.

AI summary
In manufacturing of a first electroformed component (40) and a second electroformed component (60) having portions fitted to each other into close contact, after the first electroformed component (40) is formed, the first electroformed component (40) is used as a portion of an electroforming mold to form the second electroformed component (60). Using the first electroformed component (40) as a portion of the electroforming mold to form the second electroformed component (60), the shape of the first electroformed component (40) is transferred to the second electroformed component (60). As a result, multiple types of components differing in shape may be accurately manufactured concurrently in a series of manufacturing steps.
