Problem

Existing solar-powered lighting systems face inefficiencies in converting sunlight to electrical energy and providing consistent light during darkness hours due to varying solar flux and angle, which affects energy storage and duration of light provision.

Innovation Solution

A solar-powered lighting system comprising three triangular solar panels oriented to capture optimal sunlight (west, south, and east) connected to a storage battery and LED light source, with a light diffuser and control electronics, allowing for efficient energy conversion and storage, and providing 12-14 hours of light during darkness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If solar panels are oriented to capture optimal sunlight, then energy conversion efficiency is improved, but the system complexity increases due to multiple panel orientations

Engineering Contradiction:
Improveenergy conversion efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The solar energy collection system is divided into three separate solar panels, each oriented toward a different direction (west, south, east). This segmentation allows each panel to capture sunlight from its optimal angle throughout the day, maximizing total energy conversion while maintaining manageable individual panel configurations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system transitions from a single-plane solar panel configuration to a multi-dimensional arrangement with panels facing different cardinal directions. This spatial dimensionality change enables continuous sunlight capture as the sun moves across the sky, improving productivity without requiring excessively complex tracking mechanisms.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Duration of action of moving object

If storage battery capacity is increased to provide longer lighting duration, then light provision duration is improved, but the device complexity and cost increase

Engineering Contradiction:
Improvelight provision durationVSAvoiddevice complexity
Core Design Contradiction:
Duration of action of moving objectVSDevice complexity

Solution Approach 1:

The storage battery is pre-charged during daylight hours when solar energy is abundant, storing electrical energy in advance for nighttime use. This preliminary energy accumulation allows the system to provide extended lighting duration (12-14 hours) without requiring an excessively large or complex battery system, as the battery operates within its optimal capacity range.

Inventive Principle:

3Use of energy by moving object

If LED light source efficiency is improved, then energy usage efficiency is improved, but the initial system cost increases

Engineering Contradiction:

Solution Approach 1:

The system employs LED technology which fundamentally changes the energy conversion parameters from traditional incandescent or fluorescent sources. LEDs convert electrical energy to light with significantly higher efficiency, reducing overall energy consumption and extending battery duration. This parameter change in light source technology provides long-term operational efficiency that offsets the higher initial manufacturing cost.
