Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pool and spa lighting systems require separate waterproof junction boxes and transformers, leading to complex and less aesthetically pleasing installations that do not comply with safety and regulatory standards, and are cumbersome to install.
Innovation Solution
A combined junction box and transformer with a waterproof housing, featuring separate terminals for high and low voltage, a transformer integrated within the base, and input/output ports for wiring, allowing for daisy-chaining and compliance with industry standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate waterproof junction box and transformer are used, then safety and regulatory compliance is achieved, but installation complexity increases and visual appeal deteriorates
Solution Approach 1:
The patent combines the waterproof junction box and transformer into a single integrated unit. The housing contains both the junction box with terminals and the transformer, eliminating the need for separate installations. This merging maintains safety compliance through proper isolation barriers and waterproofing while significantly reducing installation complexity and improving visual appearance.
2Reliability
If separate waterproof junction box and transformer are used, then safety and regulatory compliance is achieved, but visual appeal deteriorates
Solution Approach 1:
By integrating the transformer within the waterproof housing, the invention creates a single clean visual unit rather than multiple separate components. The housing provides a unified appearance while internal barriers maintain the required safety separations between high and low voltage components.
Solution Approach 2:
The transformer is nested within the waterproof housing, with the high voltage terminal chamber and low voltage terminal chamber arranged in nested or adjacent configurations inside the single housing. This nesting approach maintains safety separations while achieving a compact, visually appealing installation.
3Reliability
If separate waterproof junction box and transformer are used, then regulatory compliance is achieved, but installation becomes cumbersome
Solution Approach 1:
The integrated design allows installers to work with a single unit rather than coordinating installation of separate junction box and transformer components. The pre-configured internal wiring and terminal arrangements within the housing streamline the installation process while maintaining all required safety separations and code compliance.
4Ease of operation
If transformer is integrated within the base, then installation simplicity is improved, but space occupation increases
Solution Approach 1:
The transformer is nested within the base housing, utilizing the internal volume efficiently. The high voltage terminal chamber and low voltage terminal chamber are arranged to maximize space utilization while maintaining required isolation distances. This nesting approach integrates the transformer without requiring additional external space.

AI summary
A combination transformer junction box for use with pool and/or spa lighting and/or other low-voltage devices, which combination transformer junction box includes a waterproof housing having a base and a cover, a first set of terminals for low voltage, a second set of terminals for high voltage separated from the first set of terminals by a barrier, and a transformer disposed upon the base such that the transformer is within the base and does not occupy a volume defined by the cover. In one aspect a plurality of the combination transformer junction boxes may be provided together in a daisy-chain linked form configured for controlling a plurality or larger plurality of lighting and/or other low-voltage devices.
