Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical junction boxes cannot easily accommodate isolation transformers, making it difficult and visually unappealing to retrofit high-voltage lighting to low-voltage systems, especially in underwater pool lighting applications, and require separate installation of electrical parts and tools, which can be challenging for those without electrical experience.
Innovation Solution
An electrical junction box with a built-in isolation transformer that can be easily attached to existing wiring and conduits, featuring a cover with a peripheral flange to fit various base plate sizes, physically and electrically isolating high-voltage and low-voltage sections, and allowing for the use of existing junction box components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an isolation transformer is installed separately from the junction box, then electrical isolation between high-voltage and low-voltage wiring is achieved, but the installation becomes visually unappealing and requires additional electrical parts and tools
Solution Approach 1:
The patent combines the isolation transformer and junction box into a single integrated unit. The transformer housing serves as the junction box enclosure, with internal mounting structures for the transformer and external conduit entries for both high-voltage and low-voltage wiring. This integration eliminates the need for separate installation of transformer and junction box, reducing visual clutter and simplifying installation while maintaining electrical isolation between voltage circuits.
2Adaptability or versatility
If existing junction boxes are used without modification, then the original installation structure is preserved, but they cannot accommodate isolation transformers for low-voltage lighting conversions
Solution Approach 1:
The integrated transformer-junction box is designed with modular components including a removable transformer assembly, separate high-voltage and low-voltage wiring chambers, and standardized conduit entry points. This segmentation allows the unit to adapt to different retrofit scenarios while maintaining a stable external structure that can be mounted using existing junction box mounting locations.
3Object-affected harmful factors
If high-voltage lighting is converted to low-voltage lighting, then safety is improved, but additional electrical components and installation expertise are required
Solution Approach 1:
The integrated unit comes pre-configured with internal wiring pathways, mounting brackets, and conduit connections that reduce the complexity of installation. The transformer is pre-mounted within the junction box housing with accessible terminals for both high-voltage input and low-voltage output connections, allowing installers to simply connect wiring without requiring complex assembly steps or specialized electrical expertise.
