AC/DC Raceway Assembly with Junction Block
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical power systems in office environments face challenges in efficiently distributing DC power using modular configurations and raceway assemblies, often requiring multiple components and leading to unsightly and dangerous entanglements of electrical cords.
Innovation Solution
A raceway assembly is designed with a junction block having internal DC buses or wires and a DC receptacle block that can be electrically engaged, allowing for DC power distribution without the need for numerous differing components, enabling easy selection of power supply circuits through physical orientation of the receptacle block relative to the junction block.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional AC power systems with multiple components are used, then DC power distribution is achieved, but device complexity and component quantity increase
Solution Approach 1:
The raceway assembly is designed to provide both AC and DC power distribution through integrated junction blocks that contain both AC buses and DC buses. The receptacle blocks can be configured to engage with either AC or DC circuits, allowing a single system to serve multiple power distribution functions without requiring separate dedicated systems for each power type.
Solution Approach 2:
The patent combines AC and DC power distribution capabilities into a single raceway assembly system. The junction blocks integrate both AC and DC electrical circuits, and the receptacle blocks are designed to access power from either type of circuit, merging what would traditionally be separate systems into one unified infrastructure.
2Adaptability or versatility
If multiple differing components are used for DC power distribution, then DC power can be supplied, but ease of operation deteriorates due to selection complexity
Solution Approach 1:
The system segments power circuits into distinct AC and DC circuits within the junction blocks, with clearly defined physical locations. Receptacle blocks are designed to engage with specific circuits by orientation, allowing users to select AC or DC power through simple physical positioning rather than complex configuration or tool use.
3Productivity
If conventional raceway assemblies are used, then power distribution is achieved, but cord entanglements and safety hazards increase
Solution Approach 1:
The patent extracts the power receptacles from external cord-based connections and integrates them directly into the raceway assembly structure. By providing power outlets through the raceway system itself rather than requiring external cords to reach distant wall outlets, the design eliminates the harmful entanglement and tripping hazards associated with loose electrical cords while maintaining efficient power distribution.

AI summary
An AC/DC raceway assembly includes a pair of junction blocks at least one of which includes a pair of DC buses or wires carrying DC power. A DC receptacle block is electrically engageable with the junction block so that a DC receptacle on the DC receptacle block is electrically engaged with the DC buses or wires.
