Modular Fuse Holder With Integrated Clip And Rejection Features
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fuse holders do not adequately address the need for compact, space-saving designs with enhanced performance capabilities in panelboards, and they often require separate installation of panelboard clips, leading to increased costs and reliability issues due to improper installation.
Innovation Solution
A modular fuse holder assembly with a nonconductive body and a lever arm that integrates fuse rejection features and a panelboard clip, allowing for easy installation and preventing the use of incompatible fuses, along with a monitoring accessory for remote operation and safety features like audible clicks and shank locks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If existing fuse holders are used, then basic overcurrent protection function is provided, but the design is not compact and requires separate panelboard clips increasing complexity
Solution Approach 1:
The fuse holder integrates the panelboard clip directly into the holder body, combining two previously separate components (fuse holder and panelboard clip) into a single unified assembly. This eliminates the need for separate installation of clips, reducing assembly complexity while maintaining ease of installation through the integrated design.
2Reliability
If traditional fuse holders are used, then fuse installation is possible, but incorrect fuse types can be installed leading to safety issues
Solution Approach 1:
The fuse holder incorporates rejection features (such as shaped recesses or protrusions) that prevent incorrect fuse types from being installed in the first place. This preliminary preventive mechanism ensures that only compatible fuses can be inserted, eliminating the possibility of unsafe mismatches while maintaining user-friendly operation through intuitive design.
3Ease of manufacture
If modular fuse holder design is implemented, then installation is simplified and safety enhanced, but manufacturing complexity may increase
Solution Approach 1:
By integrating the panelboard clip into the fuse holder body as a unified modular component, the design simplifies the assembly process (fewer parts to handle during installation) while the integration complexity is managed through design techniques such as integral molding or pre-assembled units that maintain manufacturing efficiency.
