Stackable Battery Self-Alignment for Secure Autonomous Docking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for swappable and stackable batteries require precise alignment and timing for successful docking and charging, which can be challenging for autonomous devices to achieve, especially when batteries are low on power and need to be secured with electronic locks.
Innovation Solution
A self-locking alignment system combining mechanical and electrical actuation, featuring alignment mechanisms with locking members that can be latched mechanically and electronically, allowing for 180-degree rotational symmetry and automatic locking when one battery assembly is stacked on another, enabling secure and precise battery alignment without requiring special timing for lock actuation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electronic locks are used to secure batteries, then security is improved, but the system requires precise timing for lock actuation which increases operational complexity
Solution Approach 1:
The alignment mechanism performs self-alignment through mechanical features (guided edges, alignment pins) that automatically position the battery correctly during insertion, eliminating the need for complex timing synchronization of electronic locks and reducing operational complexity
2Reliability
If precise alignment is required for docking, then connection reliability is improved, but autonomous devices struggle to achieve this precision which reduces ease of operation
Solution Approach 1:
The system employs self-aligning mechanical features including guided edges on the battery housing and corresponding alignment pins in the receptacle that automatically position components correctly during insertion, enabling autonomous devices to achieve precise alignment without complex control systems
Solution Approach 2:
Alignment features are pre-configured in the mechanical structure (guided edges, positioning pins) that prepare and guide the battery into correct position before final connection is made, ensuring reliable docking while simplifying autonomous operation
3Measurement precision
If mechanical alignment features are added, then alignment precision is improved, but device complexity increases
Solution Approach 1:
The alignment function is merged with the existing mechanical housing structure through integrated guided edges and alignment pins, achieving precise alignment without adding separate complex alignment mechanisms or components

AI summary
Self-alignment systems for stackable batteries are disclosed herein. An example apparatus can include a lid and a container that is configured to receive and retain a battery, the lid and container being configured to enclose the battery, a first alignment mechanism positioned on a surface of the lid or the container, the first alignment mechanism having a first locking member that engages with an alignment receiver of another stackable battery assembly that is stacked with the stackable battery assembly, and an electrical interface in electrical communication with the battery, the electrical interface allowing the battery to be charged or discharged by an associated device.
