Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric vehicle charging systems often rely solely on grid connections and lack efficient protection and optimization of regenerative energy sources like solar and wind energy, leading to inefficiencies and exposure to environmental factors.
Innovation Solution
A charging system that incorporates a vertically movable lifting unit with a solar module above a wind generator, allowing optimal sunlight exposure and wind energy harvesting while protecting the wind generator from adverse conditions using a lift mechanism and sensors to adjust positions based on wind speed, and integrating with a power grid connection for secure energy supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the wind generator is exposed to the wind continuously, then wind energy conversion is maximized, but the wind generator is damaged by environmental factors during calm periods
Solution Approach 1:
The lifting unit is designed to be movable between a retracted position (where the wind generator is protected inside the receiving unit) and an extended position (where the wind generator is exposed to wind). This dynamic positioning allows the system to optimize between protection during calm periods and energy generation during windy periods, resolving the contradiction between reliability and productivity.
2Productivity
If the lifting unit is extended for wind generation, then wind energy harvesting is optimized, but the solar module is blocked from sunlight
Solution Approach 1:
The lifting unit can dynamically adjust its position to extend for wind generation or retract to allow sunlight access for the solar module. This dynamic configuration allows the system to alternate between optimizing wind energy harvesting and solar energy generation based on environmental conditions, resolving the contradiction between the two energy sources.
3Reliability
If the wind generator is housed inside the receiving unit, then protection from environmental factors is improved, but wind energy conversion is reduced
Solution Approach 1:
The system uses a movable lifting unit that can be positioned in a retracted state to protect the wind generator inside the receiving unit during calm or stormy periods, and extended state to expose the wind generator to wind for energy conversion. This dynamic positioning resolves the contradiction between protection and productivity.
4Productivity
If a lifting mechanism is added to move the lifting unit, then optimization of energy conversion and protection is achieved, but device complexity increases
Solution Approach 1:
The lifting unit serves multiple functions: it supports both the solar module and wind generator, provides structural framework, and enables dynamic positioning for both protection and energy optimization. By making the lifting unit multi-functional, the system achieves energy optimization and protection capabilities without proportionally increasing complexity.
