Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for controlling battery pack charge levels in aircraft propulsion systems lack efficiency in optimizing battery loadouts for specific flight requirements, leading to suboptimal energy storage and potential weight-related inefficiencies.
Innovation Solution
A battery replacement system that includes a controller and a vehicle with a battery storage assembly and transfer assembly, which identifies the state of charge of installed and stored battery packs, determines an energy storage prerequisite based on flight information, and adjusts the battery pack loadout by installing or removing packs to ensure sufficient combined state of charge while minimizing weight and optimizing energy storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If traditional battery charge level control systems are used, then battery management is maintained, but energy storage optimization for specific flight requirements is insufficient and weight-related inefficiencies occur
Solution Approach 1:
The system dynamically adjusts the battery pack loadout configuration based on real-time flight requirements, state of charge levels, and energy storage prerequisites. The controller continuously monitors and reconfigures which battery packs are installed on the aircraft, transitioning from a static to a dynamic optimization approach that adapts to changing operational conditions.
Solution Approach 2:
The system changes the configuration parameters of the battery loadout by selectively installing or removing battery packs based on calculated energy storage prerequisites. This involves adjusting the number and arrangement of battery packs to match specific flight requirements, thereby optimizing the energy-to-weight ratio for different operational scenarios.
2Quantity of substance
If more battery packs are installed to ensure sufficient energy storage, then energy storage capability increases, but aircraft weight increases and flight efficiency decreases
Solution Approach 1:
The system implements partial battery pack installation rather than installing all available battery packs. By calculating the precise energy storage prerequisite for each flight and installing only the necessary number of battery packs, the system avoids the excessive weight penalty of installing unnecessary battery packs while still ensuring sufficient energy storage capacity.
3Ease of operation
If manual battery pack management is used, then operational control is maintained, but time consumption increases and operational efficiency decreases
Solution Approach 1:
The system performs self-service by automatically calculating energy storage prerequisites, determining optimal battery pack configurations, and controlling the installation/removal of battery packs without requiring manual intervention. The controller autonomously manages the entire battery loadout optimization process, significantly reducing the time and labor required compared to manual battery pack management.
Solution Approach 2:
The system incorporates feedback mechanisms where the controller continuously monitors flight information, state of charge levels, and energy consumption patterns, then uses this feedback to dynamically adjust and optimize the battery pack loadout configuration for subsequent flights, creating a closed-loop optimization system.
4Productivity
If battery packs are frequently replaced to optimize loadout, then energy storage optimization improves, but system complexity and operational procedures increase
Solution Approach 1:
The controller serves multiple functions: it calculates energy storage prerequisites, determines optimal battery configurations, monitors state of charge levels, and controls battery pack installation/removal operations. By consolidating these diverse functions into a single multi-functional controller, the system achieves high operational efficiency without proportionally increasing system complexity.

AI summary
A battery replacement system for controlling a battery pack loadout for an aircraft having at least one installed battery pack includes a vehicle including a battery storage assembly, a controller, and a battery transfer assembly. The battery storage assembly is configured for storing at least one stored battery pack. The controller is configured to identify a state of charge for each of the at least one installed battery pack installed on the aircraft, identify an energy storage prerequisite for a flight or series of flights of the aircraft, and identify a battery pack loadout plan for the aircraft. The battery pack loadout plan identifies one or more of the at least one stored battery pack to be installed on the aircraft. The controller is further configured to control the battery pack loadout for the aircraft by controlling the battery transfer assembly to install the one or more of the at least one stored battery pack into the aircraft.
