Actuation Pusher Labeling Surface Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electrical connection terminals require additional space for labeling, which increases their dimensions and makes them unsuitable for certain applications, as existing solutions necessitate an extra receptacle for marking.
Innovation Solution
The actuation pusher of the electrical connection terminal features a labeling surface on an end face that can be externally marked without additional space, with a stepped and angled actuation surface for tool engagement, allowing for clear visibility and secure tool support, eliminating the need for an extra receptacle on the terminal housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If an additional receptacle is provided on the terminal housing for labeling, then the connection terminal can be clearly identified and distinguished, but the dimensions of the terminal housing increase and installation space is consumed
Solution Approach 1:
The patent combines the labeling function with the existing actuation pusher component. The labeling surface is integrated directly onto the end face of the actuation pusher, merging two functions (actuation and labeling) into a single component. This eliminates the need for a separate receptacle on the terminal housing, thereby maintaining compact dimensions while providing clear identification capability.
2Device complexity
If the labeling surface and actuation surface are arranged in the same plane, then the end face is simple in structure, but tool engagement is less secure and tool slippage may occur
Solution Approach 1:
The patent transitions from a two-dimensional planar arrangement to a three-dimensional stepped arrangement. The actuation surface is positioned at a lower level than the labeling surface, creating a vertical dimension difference. This stepped configuration provides a defined edge that prevents tool slippage while maintaining structural clarity, effectively using vertical space to enhance tool engagement security.
