Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for simulating electrostatic discharges on large solar panels in space are limited by the need for expensive and representative samples, which are costly and restricted in size, leading to non-representative results due to the inability to accurately model the propagation of discharges across the panel's surface.
Innovation Solution
A device comprising a sample coupon with photoelectric cells and an electrostatic storage unit with a metal sheet covered in dielectric material, allowing simulation and analysis of electrostatic discharges generated in the interstices of the sample and their propagation beyond, using a smaller sample to model larger panel dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a large representative solar panel sample is used for testing, then the accuracy and representativeness of electrostatic discharge simulation results is improved, but the cost and complexity of the testing setup increases significantly
Solution Approach 1:
The patent creates a simplified copy of the solar panel structure using a metal sheet with dielectric material that replicates the essential electrical characteristics (charge storage and discharge propagation) without requiring a full-scale representative panel. This copy captures the critical discharge behavior while being much simpler and cheaper to implement.
Solution Approach 2:
The invention extracts the essential functional elements needed for discharge simulation (charge storage capability and discharge path) from the complete solar panel structure. By isolating and reproducing only these critical functions using simplified components, the system achieves accurate discharge propagation simulation without the complexity of a full panel.
2Ease of manufacture
If a small sample coupon is used to reduce cost, then the testing expense is reduced, but the ability to accurately model discharge propagation across the panel surface is lost
Solution Approach 1:
The patent changes the physical parameters of the simulation model by using a metal sheet with dielectric material that, while physically small, is designed to replicate the electrical parameters (charge storage density, discharge propagation characteristics) of a much larger panel. This parameter transformation allows small physical size to represent large panel behavior.
Solution Approach 2:
The simplified model creates a functional copy of the discharge propagation phenomenon rather than a physical copy of the panel itself. The metal sheet with dielectric material copies the essential electrical behavior patterns, allowing accurate representation of discharge dynamics without requiring proportional physical dimensions.
3Ease of manufacture
If a metal sheet covered with dielectric material is used to model the panel surface, then the cost and size of the testing device is reduced, but the complexity of accurately representing the panel structure increases
Solution Approach 1:
The patent applies local quality by using dielectric material with specific properties (permittivity, thickness) that are optimized for charge storage and discharge propagation. Rather than replicating the entire complex panel structure, the model focuses on the critical local characteristics of the glass plates and their electrical behavior, using materials and dimensions specifically selected to reproduce discharge phenomena.
