Battery Engagement Detection for Secure UAV Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery safety systems for UAVs cannot reliably ensure that the battery is fully mounted and securely fixed during flight, leading to potential crashes due to loose batteries caused by user error or external factors.
Innovation Solution
A battery safety alert system comprising a detection device and a controller that detect the position information of an engagement mechanism between the battery and the battery mounting member, determining if it is fully engaged and sending an alarm if not.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an in-position signal pin is used to detect electrical connection integrity, then the UAV can detect whether the electrical connection is intact, but the system cannot guarantee that the battery is fully mounted in place
Solution Approach 1:
The patent introduces an engagement mechanism as an intermediary component between the battery and battery mounting member. This mechanism includes a detection structure that physically engages with the battery to verify its mounting position, providing an additional layer of verification beyond electrical connection detection alone.
Solution Approach 2:
The patent replaces or supplements the electrical signal-based detection system with a mechanical detection system. The engagement mechanism uses physical contact and mechanical structures (such as detection holes, protrusions, or engagement arms) to verify battery mounting position, providing more reliable position verification than electrical signals alone.
2Ease of operation
If the battery mounting structure is simplified for easy installation, then the user can quickly mount the battery, but the battery may become loose during flight due to insufficient fixation
Solution Approach 1:
The patent divides the battery mounting system into separate functional components: a battery mounting member with an engagement mechanism and a battery with a corresponding structure. This segmentation allows the mounting process to be simple (insertion) while the engagement mechanism provides secure fixation through mechanical interlocking, preventing loosening during flight.
Solution Approach 2:
The engagement mechanism is designed to automatically engage and secure the battery upon insertion. The preliminary action of inserting the battery triggers the engagement mechanism to lock into place, ensuring secure fixation before flight without requiring additional manual steps from the user.
3Device complexity
If no detection system is added, then the device complexity remains low, but the safety alert function to prevent crashes is not provided
Solution Approach 1:
The patent merges the safety detection function with the existing battery mounting structure. The engagement mechanism integrates detection holes, protrusions, or sensors directly into the mounting components, combining structural support and safety detection functions into a unified system without adding separate complex detection devices.
Solution Approach 2:
The engagement mechanism is designed to automatically detect and alert about improper battery mounting without requiring external monitoring systems. The mechanical structure itself provides the detection capability through its engagement features, and can trigger alerts or prevent operation when proper engagement is not detected, making the system self-monitoring.

AI summary
A battery safety alert system includes a detection device and a controller communicatively connected to the detection device. The detection device is configured to detect position information of an engagement mechanism provided at one of a battery and a battery mounting member. A matching mechanism is provided at another one of the battery and the battery mounting member. The engagement mechanism is configured to engage with the matching mechanism to fix the battery to the battery mounting member. The controller is configured to receive the position information, determine whether the engagement mechanism is fully engaged with the matching mechanism based on the position information, and send out alarm information in response to the engagement mechanism not being fully engaged with the matching mechanism.
