Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for determining direct sunlight levels are inaccurate and time-consuming, particularly for gardening and architectural applications, as they fail to account for varying obstructions and atmospheric effects, leading to improper light exposure for plants and inefficient energy utilization in structures.
Innovation Solution
A software application running on a computer device that computes the sun's paths across the sky, guides the user to capture images, and maps solar paths to determine the average time sunlight can strike a location, considering obstructions and atmospheric factors, providing a power factor for insolation estimation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional methods are used to determine direct sunlight levels, then the process is simple, but the accuracy and reliability of the determination are poor
Solution Approach 1:
The system segments the sunlight determination process into multiple components: solar path computation, image capture at specific intervals, obstruction detection, and insolation calculation. This segmentation allows each component to be optimized independently while maintaining overall system accuracy without excessive complexity.
Solution Approach 2:
The system performs preliminary computation of solar paths across the sky before actual measurement. By pre-calculating where the sun will be at different times and positions, the system can then systematically capture images at these predetermined locations, ensuring comprehensive coverage without missing critical sunlight exposure periods.
2Measurement precision
If comprehensive solar path tracking and image capture are performed, then measurement precision improves, but time consumption increases
Solution Approach 1:
The system implements periodic image capture at predetermined intervals along the computed solar paths. Rather than continuous monitoring, images are captured at specific time points that correspond to key positions in the sun's trajectory, maintaining measurement accuracy while significantly reducing the time and computational resources required.
Solution Approach 2:
Solar paths are pre-computed before the measurement process begins. This preliminary action allows the system to know exactly where and when to capture images, eliminating the need for real-time sun tracking and adjustment during the measurement process, thus reducing overall determination time.
3Reliability
If traditional sunlight determination methods are used, then the process is quick, but the reliability for gardening and architectural applications is poor
Solution Approach 1:
The system introduces an intermediary computational layer that bridges simple image capture and reliable sunlight determination. By computing solar paths and using these as reference frameworks for analyzing captured images, the system transforms ordinary photographs into reliable data about actual sunlight exposure, accounting for obstructions and atmospheric effects without requiring complex specialized equipment.
Solution Approach 2:
The system is designed to serve multiple applications (gardening, architecture, energy planning) through a single unified approach. The same core methodology of solar path computation combined with image analysis provides reliable data for different purposes, eliminating the need for application-specific complex systems while maintaining high reliability across diverse uses.
