Pivotable Solar Panels on Intermodal Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable solar power systems integrated into standard intermodal containers are inefficient in snowy climates due to snow accumulation and weight issues, and are limited by horizontal panel configurations that do not account for latitude, leading to reduced power output.
Innovation Solution
The system features pivotable solar panels secured to a top bracket, allowing them to be angled relative to the container, with support braces extending between the panels and the container to maintain an optimal tilt angle for sunlight capture, independent of the container's length, thus maximizing power generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If solar panels are positioned horizontally on the container, then installation is simple and structure is stable, but power output is reduced due to inability to capture maximum sunlight at optimal angles
Solution Approach 1:
The patent applies the dynamics principle by making the solar panels rotatable about a vertical axis, allowing them to dynamically adjust their orientation to track the sun's movement across the sky. This rotational capability enables the panels to maintain optimal incident angles throughout the day, maximizing power capture while preserving installation simplicity through a relatively straightforward mounting mechanism.
2Productivity
If solar panels are cantilevered outwards from the container, then more panels can be installed to increase power output, but snow accumulation on cantilevered panels may cause collapse due to excessive weight
Solution Approach 1:
The patent applies the dimensionality change principle by rotating the solar panels about a vertical axis rather than extending them horizontally outward. This vertical rotation allows the panels to be positioned in a different spatial dimension, capturing sunlight from various angles without requiring cantilevered extensions that would be vulnerable to snow load. The panels remain supported by the container structure while achieving enhanced power output.
3Productivity
If solar panels are positioned at a fixed angle to capture maximum sunlight, then power output is optimized, but snow accumulation on angled panels blocks sunlight and may damage panels with weight
Solution Approach 1:
The patent applies dynamics by enabling the panels to rotate about a vertical axis, allowing them to adapt their orientation dynamically. In snowy conditions, the panels can be rotated to positions where snow accumulation is minimized or where the panels can be more easily cleared, while still maintaining effective sunlight capture during operational periods. This dynamic adjustment capability mitigates the harmful effects of snow accumulation.
Solution Approach 2:
The patent applies composite materials by using a mounting structure that combines the container body with rotational mounting mechanisms. This composite structure allows the panels to be securely attached while maintaining the ability to rotate and adjust, providing both structural support and operational flexibility to应对 snow and other environmental conditions.
4Reliability
If solar panel array width is limited to the container length, then all panels can be supported by the main body, but potential power output is limited
Solution Approach 1:
The patent applies dimensionality change by utilizing vertical rotation about a vertical axis mounted on the container. This allows the solar panels to extend their effective coverage area in a different dimension rather than being constrained to horizontal expansion limited by container length. The rotational mechanism enables panels to sweep through a larger angular range, effectively increasing the array width and power potential while maintaining stable support from the container's mounting structure.
