Solution Overview
Problem
Conventional illuminated signs rely on the electrical grid for power, limiting their use to areas with access to a power grid and incurring substantial energy costs, especially for signs that need to operate continuously and be readable in dark conditions.
Innovation Solution
A portable illuminated sign equipped with two solar panels mounted at an adjustable angle, which convert solar energy into electricity to charge a battery, powering an LED light panel for continuous operation day and night, even in remote areas without access to a power grid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If illuminated signs are powered by the electrical grid, then the signs can be illuminated in dark conditions, but the signs are limited to areas with power grid access and incur substantial energy costs
Solution Approach 1:
The sign system generates its own electricity through solar panels that convert sunlight into electrical energy, storing it in a battery for nighttime operation. This self-powered approach eliminates dependence on external power grids, enabling deployment in remote locations without sacrificing illumination capability
Solution Approach 2:
The solar-powered sign system can be deployed in multiple locations including remote areas, event venues, and temporary installations where traditional grid-powered signs cannot be used. The system universally provides illumination functionality across diverse locations without requiring infrastructure changes
2Illumination intensity
If illuminated signs are powered by the electrical grid, then the signs can be illuminated in dark conditions, but the energy costs are substantial for continuous operation
Solution Approach 1:
The solar panels capture and convert solar energy into electrical energy during daytime hours when sunlight is available, storing the energy in a battery before nighttime operation. This preliminary energy accumulation during the day enables free illumination at night without incurring grid electricity costs
Solution Approach 2:
The system generates its own operational energy through solar conversion, eliminating the need to purchase electricity from external sources. The battery-stored solar energy provides free, sustainable power for continuous sign illumination without ongoing energy costs
3Adaptability or versatility
If solar panels are mounted on the sign, then the sign can operate in remote areas, but the device complexity increases
Solution Approach 1:
The solar panels, battery, controller, and sign structure are integrated into a unified system where the solar panels are mounted directly on the sign housing. This consolidation combines multiple components into a single deployable unit, reducing the practical complexity despite adding functional elements
