Fuse Plug-In Connector Handle With Integrated Marking and Indicator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plug-in connectors for fuse elements face challenges in accommodating a handle part, markings, and light indicators within limited geometrical constraints, making them difficult to maneuver and visually informative.
Innovation Solution
A plug-in connector design featuring a handle part with an actuating portion and linking portion that allows for easy insertion and removal, incorporates a marking element on the actuating surface without additional space, and includes a compartment for a light indicator, enabling visibility and functionality without increasing size, with a breakable linking portion for reduced length and symmetrical mounting options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the plug-in connector is made small to fit limited spaces, then the size is reduced, but the handle part becomes difficult to maneuver
Solution Approach 1:
The handle part extends in a direction transverse to the insertion axis, utilizing a different spatial dimension. This allows the handle to provide sufficient maneuverability while keeping the main body of the plug-in connector compact and suitable for limited spaces.
2Loss of information
If additional elements such as markings or light indicators are added to the plug-in connector, then the information visibility is improved, but the geometrical constraints become more difficult to deal with
Solution Approach 1:
The marking element is integrated directly onto the actuating surface of the handle part, merging the marking function with the existing handle structure. This eliminates the need for separate marking components and simplifies the overall geometry while maintaining information visibility.
Solution Approach 2:
The actuating surface of the handle part serves multiple functions: it provides the gripping surface for manual operation and simultaneously serves as the substrate for the marking element. This multi-functionality reduces the need for additional components and simplifies the geometrical design.
3Loss of information
If a light indicator is added to the plug-in connector, then the status visibility is improved, but the space requirements increase
Solution Approach 1:
The light indicator is positioned within the compartment that accommodates the fuse element, nesting the indicator within the existing structural space. This allows the light indicator to be visible through the front face while utilizing internal space that would otherwise be empty or unused.
