Self-Adjusting Busway Joint with Movable Braces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical busway systems require custom-length joints, which are costly and time-consuming to manufacture, as fixed-length busway sections often do not match specific installation lengths, necessitating the need for adjustable busway joints that can extend or contract without disrupting the entire busway run.
Innovation Solution
A busway joint system featuring movable assemblies with conductive splice plates, insulation laminations, and bracing mechanisms that allow for longitudinal adjustment between busway sections, enabling secure connection and thermal management while maintaining electrical continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If fixed-length busway sections are used, then manufacturing and distribution is simplified, but custom length busway joints must be manufactured adding significant cost and time to installation
Solution Approach 1:
The busway joint incorporates movable assemblies with conductive splice plates that can slide relative to each other along the conductors, enabling the joint to dynamically adjust its length. This dynamic mechanism allows the joint to accommodate varying distances between busway sections without requiring custom manufacturing, thus reducing both cost and installation time while maintaining standard production processes
2Adaptability or versatility
If custom length busway sections are ordered, then specific installation length requirements are met, but manufacturing delivery time delays installation completion
Solution Approach 1:
The joint's movable assemblies enable real-time length adjustment during installation, providing adaptability to specific site requirements without waiting for custom manufacturing. The mechanism allows installers to configure the joint to match the actual distance between busway sections on-site, eliminating delivery delays while maintaining precise length adaptation
Solution Approach 2:
The busway joint system enables on-site configuration where installers can independently adjust the joint length to match installation requirements without external manufacturing support. The self-adjusting mechanism allows the system to service its own customization needs during installation, eliminating dependence on custom manufacturing lead times
3Ease of operation
If busway sections are connected at non-standard distances, then installation flexibility is improved, but conventional fixed-length joints cannot accommodate the variable spacing
Solution Approach 1:
The movable assemblies with sliding splice plates create a dynamically adjustable joint that can accommodate any distance between busway sections within its range. This dynamic structure provides both installation flexibility through easy adjustment and adaptability to variable spacing requirements, resolving the contradiction between operational ease and length accommodation

AI summary
A busway system is provided. The busway system includes a first electrical busway section, a second electrical busway section, and a busway joint. The first and second electrical busway sections are disposed longitudinally offset from each other. The busway joint couples the first and second busway sections. The busway joint includes a first assembly coupled to the first busway section, a second assembly coupled to the second busway section, a plurality of conductors coupled to the first and second assemblies, a first movable brace coupled to the conductors, and a first brace locator coupled to the movable brace. The first and second assemblies move relative to each other between a collapsed position and an extended position. The first movable brace moves longitudinally along a length of the conductors. The first brace locator locates the first movable brace at a first position when the first assembly is in the extended position.
