Automatic battery replacement apparatus, moving platform, and rechargeable battery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional moving platforms with rechargeable batteries face reduced operational efficiency due to the need to stop operations for battery charging, which interrupts their movement and tasks.
Innovation Solution
An automatic battery replacement apparatus comprising a movable carrier, a charging station, and a battery replacement module with a driving gear that allows for the automatic interchange of rechargeable batteries, enabling continuous operation by switching batteries without stopping the platform's movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the moving platform stops to charge the battery at the charging station, then the battery can be recharged, but the operation efficiency of the moving platform is reduced
Solution Approach 1:
The battery system is segmented into multiple rechargeable batteries that can be independently replaced. The moving platform carries a battery carrier with multiple battery slots, allowing one battery to be replaced while others continue providing power or charging, thus eliminating the need to stop operations for recharging.
Solution Approach 2:
Batteries are pre-charged at the charging station before being installed in the moving platform. The battery carrier automatically replaces depleted batteries with pre-charged ones, so the platform never needs to stop for charging purposes.
2Duration of action of stationary object
If a charging mechanism stops the operation of the moving platform for battery charging, then the battery can be charged, but the operation efficiency is reduced
Solution Approach 1:
The battery replacement system is dynamic and automated. The battery carrier can automatically exchange batteries with the moving platform while both are in motion, transforming the static charging process into a dynamic replacement process that occurs during operation rather than requiring downtime.
Solution Approach 2:
The battery carrier acts as an intermediary between the charging station and the moving platform. It receives pre-charged batteries from the charging station and supplies them to the platform, decoupling the charging process from the platform's operational timeline and eliminating downtime.
3Productivity
If the moving platform continuously operates without battery replacement, then operation efficiency is maintained, but the battery will deplete and require charging which interrupts operation
Solution Approach 1:
Different batteries in the carrier have different states of charge (local quality variation). When one battery depletes, others with remaining charge can immediately take over, ensuring continuous power supply. The system exploits the varying charge states of individual batteries to maintain overall system reliability.
Solution Approach 2:
Depleted batteries are automatically discarded from the platform and returned to the charging station for recharging, while fresh batteries are recovered and installed. This continuous cycle of discarding depleted batteries and recovering charged ones ensures uninterrupted power supply and maintains operational reliability.
