Electrical Box Jaws with Sliding Pivots for Busbar Conduits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing busbar conduit connection boxes require complex and costly locking mechanisms to adjust and stabilize their position on conduits of varying sizes and configurations, leading to fabrication and installation challenges.
Innovation Solution
The design features jaws with sliding pivots that can adjust in both vertical and horizontal directions, using guides to maintain stable positioning without the need for complex locking systems, allowing the box to fit various conduit sizes and configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If fixed pivots are used to prevent translation of jaws, then positioning precision is improved, but adaptability to different conduit configurations deteriorates
Solution Approach 1:
The patent transforms fixed pivots into sliding pivots that can dynamically adjust their positions along guide slots. The guides extend in directions that allow pivots to move and adapt to different conduit sizes and configurations, while still maintaining stable positioning when engaged. This dynamic capability resolves the contradiction between fixed positioning precision and adaptability.
2Adaptability or versatility
If sliding pivots are used to increase adaptability, then versatility is improved, but stability deteriorates due to pivot movement
Solution Approach 1:
The patent introduces guides as intermediary elements between the pivots and the box structure. These guides constrain pivot movement to specific paths and provide stable reference points, allowing the sliding pivots to adapt to different configurations while maintaining stability during operation. The guides act as mediators that enable both versatility and stability.
3Stability of the object's composition
If complex locking mechanisms are added to stabilize sliding pivots, then stability is improved, but device complexity increases
Solution Approach 1:
The patent designs the guides with self-centering features and engagement mechanisms that automatically stabilize the sliding pivots during installation and operation. The guides themselves provide the stabilizing function through their geometric design, eliminating the need for separate locking mechanisms. This self-service approach maintains stability while avoiding additional complexity.

AI summary
A box (1) for electrical components adapted to be fixed to various busbar conduits (100) comprises two jaws (3), that are rotatably attached to a side wall (22a, 22b, 22c, 22d) of a container (2). The jaws (3) have attachment members (32) configured to attach the jaw (3) to a busbar conduit or various types of busbar conduits (100). The two jaws (3) are adapted to be rotated about respective pivots (25) to move the attachment members (32) toward and/or away from each other. Each pivot (25) is slidable along a respective guide (4), which extends between a first end (41) and a second end (42), the latter being spaced apart in the longitudinal direction (Y-Y). The guides (4) are shaped such as to prevent the pivots (25) from moving in the longitudinal direction (Y-Y) toward the second ends (42), when the pivots (25) are located at the first ends (41).
