Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing busway systems face challenges in reducing space requirements and flexibility in electrical power distribution, particularly in high-rise buildings, where space is limited and cable and conduit assemblies are difficult to modify once installed.
Innovation Solution
A pocketed multi-bolt joint stack is used to connect busway sections and a tap box, allowing for compact and flexible electrical power distribution by creating pockets for electrical stabs, enabling easy assembly and modification while maintaining electrical continuity and mechanical support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cable and conduit assemblies are used for power distribution, then electrical power can be delivered and distributed, but the assemblies are difficult to change once installed
Solution Approach 1:
The busway system is divided into modular sections that can be easily connected and disconnected. Each busway section contains conductors within an enclosure and can be independently installed, removed, or reconfigured without affecting the entire system, enabling flexible modification of power distribution paths.
Solution Approach 2:
The joint stack design incorporates movable and adjustable components that allow the busway system to be dynamically reconfigured. The system transitions from a static cable installation to a dynamic modular assembly that can adapt to changing electrical distribution requirements through simple connection changes.
2Adaptability or versatility
If traditional busway systems are used, then electrical power distribution is provided, but space requirements are not optimized
Solution Approach 1:
The conductors are nested within an enclosure forming a compact busway section. The joint stack nests multiple components including conductive plates, insulating plates, and bolts in a layered configuration. This nesting arrangement minimizes the space occupied by the power distribution system while maintaining all necessary electrical and mechanical functions.
Solution Approach 2:
The system optimizes space by transitioning from horizontal cable tray arrangements to vertical busway sections connected through joint stacks. This dimensional reorganization allows power distribution to occupy less floor space and better utilize vertical space in building environments.
3Reliability
If busway sections are connected with traditional joints, then electrical continuity is maintained, but the connection is not compact or flexible
Solution Approach 1:
The joint stack merges multiple functions into a single integrated component: electrical continuity through conductive plates, mechanical connection through bolts, and insulation through insulating plates. This consolidation creates a compact connection structure that maintains reliable electrical continuity while reducing overall system complexity and space requirements.

AI summary
A multi-bolt joint stack for use in an electrical power distribution system. The joint stack includes (1) a plurality of conductive plate sets, each plate set including a first conductive plate and a second conductive plate separated by a first spacer and a second spacer; (2) a first clamping bolt extending through the plurality of conductive plate sets and the first spacer of each conductive plate set; and (3) a second clamping bolt extending through the plurality of conductive plate sets and the second spacer of each conductive plate set. The first and second clamping bolts are separated from each other to define a plurality of pockets within the joint stack, each pocket being formed by the first and second conductive plates and first and second spacers of the plurality of conductive plate sets. The pockets are configured to receive electrical stabs. Numerous other aspects are provided.
