Non-stop Battery Exchange System with Voltage Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery exchanging methods require systems to be stopped and powered off to replace batteries, disrupting continuous operation of apparatuses like electric vehicles and robots.
Innovation Solution
A non-stop battery exchanging system that includes a battery with a locking protrusion, a main body with a receiving groove, a battery separating unit, a battery mounting unit, and a power supply unit to compensate for voltage differences, allowing for seamless battery replacement without stopping the system's operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system is stopped to separate and exchange the battery, then the battery can be successfully replaced, but the operation continuity of the apparatus is disrupted and downtime increases
Solution Approach 1:
The battery exchanging system is divided into independent functional modules: a battery separating unit that detaches the used battery, and a battery mounting unit that installs the charged battery. This segmentation allows the battery exchange process to occur without stopping the main apparatus operation, as each module operates independently to maintain system continuity.
Solution Approach 2:
A power supply unit acts as an intermediary during the battery exchange process. It provides temporary power compensation to bridge the voltage difference generated when the battery is separated and mounted, ensuring that the apparatus maintains continuous operation without interruption or downtime.
2Productivity
If the system stops operation to exchange battery, then power source can be cut and battery replaced safely, but productivity and operational efficiency decrease
Solution Approach 1:
The battery separating unit and mounting unit are pre-configured with locking protrusions, locking grooves, and guide structures that automatically align and secure the battery during exchange. This preliminary configuration enables rapid battery replacement without requiring manual intervention or system shutdown, thereby maintaining high productivity and operational efficiency.
Solution Approach 2:
The battery exchange mechanism is designed to perform the replacement operation automatically through the interaction of the separating unit and mounting unit. The locking protrusions and grooves engage automatically, and the power supply unit self-regulates voltage compensation, eliminating the need for manual battery replacement and system shutdown procedures.
3Duration of action of stationary object
If battery exchange is performed without stopping the system, then operation continuity is maintained, but voltage difference compensation and power supply stability become critical challenges
Solution Approach 1:
The power supply unit continuously monitors the voltage difference generated during battery separation and mounting operations. It dynamically adjusts power compensation in real-time to maintain stable voltage levels, ensuring that the apparatus operates without interruption and that power stability is maintained throughout the battery exchange process.
