Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If high-capacity batteries are integrated into the solar canopy for energy storage, then the ability to charge electric vehicles using stored renewable energy is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines multiple functions into a single integrated structure: the solar canopy serves as both a protective shelter and an energy generation/storage system. Photovoltaic panels are integrated into the canopy surface, batteries are housed within the canopy structure, and EV charging stations are incorporated into the same structure, creating a multi-functional energy hub that reduces overall system complexity despite adding capabilities.
Solution Approach 2:
The solar canopy system is designed to perform multiple functions simultaneously: generating electricity through photovoltaic panels, storing energy in integrated batteries, charging electric vehicles through dedicated stations, providing protective shelter, and potentially serving as architectural infrastructure. This multi-functionality justifies the increased complexity by delivering comprehensive energy solutions in a single integrated platform.
2Use of energy by moving object
If solar panels and batteries are integrated into the canopy structure, then renewable energy generation and storage are improved, but the weight and structural requirements increase
Solution Approach 1:
The patent merges the canopy structure with energy generation and storage components. The canopy framework serves dual purposes as both structural support for the shelter and mounting structure for photovoltaic panels and batteries. This integration means the structural elements are already in place to support the energy components, avoiding the need for separate supporting infrastructure and reducing overall weight compared to discrete installations.
Solution Approach 2:
The energy storage batteries are strategically positioned within specific compartments of the canopy structure where weight distribution can be optimized. The canopy design allows for localized reinforcement only where energy components are installed, rather than requiring uniform strengthening throughout the entire structure, thus minimizing unnecessary weight addition.
3Loss of energy
If the system charges electric vehicles during off-peak hours using stored energy, then energy cost efficiency is improved, but the charging speed and availability during peak demand may be limited
Solution Approach 1:
The system performs preliminary energy storage during off-peak hours when electricity costs are lower and renewable energy generation is sufficient. Batteries are charged during these periods, preparing stored energy for later use during peak demand periods when grid electricity is expensive and less reliable. This advance preparation enables cost-efficient operation while ensuring energy availability when needed.
Solution Approach 2:
The solar canopy maintains continuous energy availability by combining real-time solar generation with stored battery energy. While batteries charge during off-peak hours, the photovoltaic panels continue generating electricity during daytime operations, and the system can seamlessly switch between grid power, solar generation, and battery storage to maintain uninterrupted EV charging capability throughout different demand periods.
4Productivity
If multiple EV charging stations are incorporated into the canopy, then the charging capacity and serviceability are improved, but the device complexity and space requirements increase
Solution Approach 1:
The patent integrates multiple EV charging stations within the confined space of the canopy structure by combining charging infrastructure with the canopy's protective enclosure. The canopy interior space is utilized to house charging equipment, control systems, and battery storage, allowing multiple charging points to be accommodated without requiring additional ground space beyond the canopy's footprint.
Solution Approach 2:
The charging stations are nested within the canopy structure, with charging equipment, control systems, and energy storage components arranged in hierarchical configurations. This nesting allows multiple functional elements to be packed efficiently within the limited spatial envelope of the canopy, maximizing charging capacity while minimizing overall space requirements.
