Multi-Battery Robot Design for Extended Operation Duration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-battery-equipped robots rely on a single rechargeable battery, which shortens the operation duration due to limited battery life.
Innovation Solution
A multi-battery-equipped robot design featuring at least two battery assemblies, each with a battery pack and a circuit board, allowing for real-time voltage monitoring and flexible power supply configurations, such as series or parallel connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a single rechargeable battery is used to supply power, then the device complexity is reduced, but the operation duration of the robot is shortened
Solution Approach 1:
The battery system is segmented into multiple independent battery packs (at least two) that can be individually installed and removed. Each battery pack is a separate module that can be independently managed, allowing the robot to extend its operation duration by using multiple packs instead of a single large battery, while maintaining ease of replacement and management.
2Power
If multiple battery packs are connected in series, then the power supply capacity is improved, but the voltage monitoring complexity increases
Solution Approach 1:
Each battery pack is equipped with a circuit board that includes a voltage detection module. These modules continuously monitor the voltage of their respective battery packs and provide feedback signals to the control box. The control box processes these feedback signals to display real-time voltage information, enabling the system to safely operate with multiple battery packs connected in series without excessive monitoring complexity.
3Ease of operation
If battery assemblies are made detachable, then the ease of operation is improved, but the connection reliability may be reduced
Solution Approach 1:
The circuit boards are pre-equipped with connection terminals and wiring harnesses that are designed to automatically connect to corresponding terminals on the control box and between battery packs when the battery assemblies are inserted. This preliminary preparation of connection interfaces ensures that when users detach or attach battery packs, the electrical connections are reliably established without requiring complex manual wiring, thus maintaining both ease of operation and connection reliability.

AI summary
A multi-battery-equipped robot includes a casing assembly, a control box provided within the casing assembly, a driving motor, a suction motor and at least two battery assemblies. The driving motor is detachably provided on an inner wall of the casing assembly. The suction motor is detachably provided on an inner bottom surface of the casing assembly. Each battery assembly includes a battery pack and a circuit board. An outer wall of the casing assembly is provided with a slot, in which the battery assemblies are detachably provided. The battery pack is electrically connected to the circuit board through a first cable. The circuit board is electrically connected to the control box through a second cable. Any two circuit boards are electrically connected to each other through a third cable.
