Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional insulators are designed for either parallel or serial wire connections, limiting their versatility and requiring separate insulators for different connection methods, which increases costs and complexity.
Innovation Solution
A single insulator design featuring slits for both parallel and serial wire connections, with shared slits that function as conducting wire extraction parts for both methods, allowing for flexible selection of connection systems and reducing mold costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate insulators are designed for parallel and serial wire connections, then each insulator can be optimized for its specific connection method, but the overall device complexity increases and manufacturing costs rise
Solution Approach 1:
The insulator is designed with multiple slits that can serve different functions depending on the connection method used. The first slit extracts conducting wires for parallel connections, while the second slit extracts conducting wires for serial connections. This multi-functional design allows a single insulator to replace what would traditionally require two different insulator designs, reducing device complexity while maintaining connection reliability for both parallel and serial configurations.
2Reliability
If separate insulators are designed for parallel and serial wire connections, then each insulator can be optimized for its specific connection method, but manufacturing costs increase due to multiple mold requirements
Solution Approach 1:
By designing a single insulator with multiple slits that can accommodate both parallel and serial wire connections, the invention eliminates the need for separate molds for different connection types. The first slit is configured for parallel connection wire extraction, while the second slit is configured for serial connection wire extraction, allowing one mold to produce insulators suitable for both connection methods, thereby reducing manufacturing costs.
Solution Approach 2:
The insulator is segmented into multiple functional regions with distinct slits positioned at different locations. The first slit is positioned to extract conducting wires for parallel connections, while the second slit is positioned for serial connections. This segmentation allows each slit to be optimized for its specific function while being integrated into a single insulator component that can be manufactured using a single mold.
3Device complexity
If a single insulator design is used for both parallel and serial connections, then manufacturing costs and device complexity are reduced, but the insulator must accommodate different connection methods
Solution Approach 1:
The insulator achieves universality by incorporating multiple slits with different configurations within a single component. The first slit has a specific shape and position optimized for parallel wire extraction, while the second slit has a different shape and position optimized for serial wire extraction. This multi-functional design enables the single insulator to adapt to different connection methods without compromising the versatility needed for both parallel and serial configurations.
