Solution Overview
Problem
Existing electric powered paragliders face challenges with maintaining equal battery charge across multiple batteries, leading to weight imbalance and inefficient battery swapping processes, which hinder effective operation.
Innovation Solution
The electric powered paraglider incorporates a power latching unit with a battery management system that allows for uniform state of charge maintenance across batteries and a quick swap mechanism, along with a weight balancing unit to address these issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If multiple batteries are used to power the electric motor, then the flight duration and power supply are improved, but weight imbalance and charge distribution complexity increase
Solution Approach 1:
The battery management system automatically monitors and manages the charge state of multiple batteries without external intervention. It performs self-testing, self-diagnosis, and automatic charge distribution balancing, allowing the system to maintain optimal operation autonomously and reducing the operational burden on the user.
Solution Approach 2:
The system continuously monitors the charge state, voltage, and temperature of each battery through sensors and communication modules. This feedback is processed by the control unit, which adjusts charge distribution in real-time to maintain balance and prevent overcharging or undercharging of individual batteries.
2Use of energy by moving object
If multiple batteries are used to extend flight duration, then the energy supply is improved, but weight imbalance in the paraglider increases
Solution Approach 1:
The battery system is divided into multiple independent battery units, each with its own management and monitoring. This segmentation allows for flexible arrangement and independent management of each battery, making it easier to distribute weight evenly across the paraglider structure while maintaining total energy capacity.
Solution Approach 2:
Different batteries can be positioned at different locations on the paraglider frame based on weight balance requirements. The system allows for localized optimization of battery placement, with each battery unit having specific charge and discharge characteristics tailored to its position and function in the overall energy management system.
3Ease of operation
If traditional battery swapping is used, then battery replacement is possible, but the process is tedious and time-consuming
Solution Approach 1:
Multiple batteries are electrically connected and managed as a single integrated power system. The battery management system combines the charge states and capacities of individual batteries, allowing them to be treated as one unified energy source. This enables simpler swapping procedures where entire battery packs can be replaced as units rather than managing individual cells.
Solution Approach 2:
The system pre-charges backup batteries and maintains them in optimal charge state ready for immediate substitution. The battery management system monitors charge levels continuously and prepares replacement batteries in advance, so when swapping is needed, the process can be completed quickly without delay for charging or complex management procedures.
