Junction Box Controller for Centralized Pool Accent Light Control

Solution Overview

Problem

Existing pool and spa lighting systems face challenges with the size and weight of on-board controllers, limiting their installation locations, and the cost of central controllers that control multiple systems, making it difficult to achieve centralized control of accent lights without additional equipment.

Innovation Solution

The system includes accent lights with a junction box controller that can be installed in conduits or pipes, featuring a microcontroller and associated circuitry for remote control, allowing for flexible placement and central control of lights, along with an underwater luminaire and method for determining manufacturer-specific LED control signals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If on-board controllers are integrated into accent lights, then centralized control capability is achieved, but the size and weight of the lights increase

Engineering Contradiction:
Core Design Contradiction:
Extent of automationVSWeight of moving object

Solution Approach 1:

The control system is segmented into two parts: a simple light engine in the accent light and a sophisticated junction box controller that handles all control logic. This separation allows the light to remain small and lightweight while still achieving centralized control through the junction box.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The controller is extracted from the accent light and relocated to the junction box. This extraction removes the weight and complexity from the light itself while maintaining the ability to centrally control multiple lights through the junction box infrastructure.

Inventive Principle:
Principle #2Taking out (Extraction)

3Extent of automation

If existing central controllers are used to control pool/spa lights, then centralized control is achieved, but the cost of the system increases

Engineering Contradiction:
Core Design Contradiction:
Extent of automationVSQuantity of substance

Solution Approach 1:

The junction box controller is designed to control multiple different types of pool and spa equipment (lights, filters, pumps, heaters, chlorinators) through a single device. This multi-functionality eliminates the need for separate controllers for each device, reducing overall system cost while maintaining centralized control capability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system uses existing infrastructure (junction boxes and wiring) to provide control functionality, rather than requiring additional dedicated control equipment. The junction box leverages existing electrical infrastructure to deliver centralized control at minimal additional cost.

Inventive Principle:
Principle #25Self-service
