Busbar Mounting Latch Geometry for Secure Front-Side Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting portions and adapters for electrical installation devices face challenges when the pivot point for the latching arm is unable to be placed behind the front surface of the busbar or cover, making it difficult to achieve a self-reinforcing clamping force.
Innovation Solution
A mounting portion with a latching arm that grasps an attachment point below the top edge of the busbar, defining a concave arc with a predefined radius, and a center point located behind the attachment point, combined with a spring mechanism to provide a clamping force, ensuring secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pivot point of the latching arm is placed behind the front surface of the busbar, then a self-reinforcing clamping force is achieved, but the space behind the front surface is required which may be used or needed for other elements
Solution Approach 1:
The patent inverts the traditional pivot point location by placing it in front of the busbar front surface rather than behind it. This inversion allows the latching arm to function effectively without requiring space behind the busbar, while still achieving secure engagement through the alternative geometric arrangement of the arc-shaped arm and pivot point
Solution Approach 2:
The patent changes the spatial dimension by positioning the pivot point at a different location (in front of the busbar) and using an arc-shaped latching arm that engages the busbar from a different geometric perspective. This dimensional repositioning resolves the space conflict while maintaining the securing function
2Force
If the latching arm is articulated to grasp the busbar system, then additional clamping force is produced when lifting is attempted, but the pivot point location becomes constrained
Solution Approach 1:
The patent employs an arc-shaped latching arm with a specifically defined radius that corresponds to the curvature of the busbar. This curved geometry allows the arm to engage the busbar effectively and produce clamping force through rotational movement about the pivot point, achieving the desired force mechanism while simplifying the overall structure by eliminating the need for a complex pivot mechanism behind the busbar

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures a secure and reliable attachment of the mounting portion to the busbar system, even when the pivot point is not accessible from the front, by utilizing a latching arm and spring mechanism to enhance clamping force.
