Fuse Adapter with Adjustable Contacts for Mount Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Power distribution system operators face challenges when trying to replace obsolete fuse types with new ones, as existing fuse mounts are often specific to particular fuse designs, leading to costly and environmentally impactful replacements when new fuse technology is introduced.
Innovation Solution
An installation adapter kit that allows fuses to be adapted for non-standard mounts by using adapter members with adjustable electrical contacts, enabling compatibility with different fuse types and configurations, including dual operating characteristics for fault current management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fuse mounts are designed to be specific to particular fuse designs, then the reliability of the fuse-mount connection is improved, but the adaptability to different fuse types deteriorates
Solution Approach 1:
An adapter member is introduced as an intermediary component between the fuse and the mount. The adapter member includes electrical contacts that can be adjusted to different positions, allowing it to interface with various fuse types while maintaining a standardized connection to the mount, thus resolving the contradiction between connection reliability and fuse type adaptability
2Adaptability or versatility
If fuse mounts are replaced to accommodate new fuse types, then the adaptability to new fuse technology is improved, but the cost and environmental impact deteriorate
Solution Approach 1:
The adapter member is designed to be universally compatible with multiple fuse types through adjustable electrical contacts. This allows a single adapter design to work with various fuse configurations, enabling the existing mount to accommodate new fuse types without replacement, thereby reducing material waste and costs while maintaining adaptability
3Adaptability or versatility
If adjustable electrical contacts are used in the adapter, then the adaptability to different fuse configurations is improved, but the device complexity deteriorates
Solution Approach 1:
The adapter member incorporates adjustable electrical contacts that can be dynamically positioned to match different fuse configurations. This dynamic adjustability allows the adapter to adapt to various fuse types without requiring multiple fixed designs, balancing adaptability with manageable complexity through a single reconfigurable component
