Construction Robot Battery Swap Design for Minimal Downtime
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Construction robots are expensive to manufacture and require high manufacturing costs due to the use of high-capacity batteries, which also result in extended charging times and reduced availability, making them bulky and limiting their operational reach.
Innovation Solution
A construction robot with a swappable battery compartment that allows for quick battery replacement, enabling high availability and reduced downtime, using interchangeable batteries with lower capacity and allowing simultaneous charging of additional batteries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a battery with extraordinarily high capacity is used to extend operating time, then the running time without interruption is increased, but the charging time is extended and manufacturing costs increase
Solution Approach 1:
The patent divides the battery system into multiple separate battery units (first battery and second battery) that can be independently charged and swapped. This segmentation allows the robot to use one battery while another is being charged, eliminating the need to wait for a single large battery to charge, thus resolving the contradiction between extended running time and reduced charging downtime.
Solution Approach 2:
The patent implements preliminary charging of multiple battery units before operation. The second battery can be charged in advance while the first battery is in use, so that when the first battery is depleted, the second battery is already ready for immediate swap. This preliminary action eliminates charging wait time during operation.
2Duration of action of moving object
If a battery with extraordinarily high capacity is used to extend operating time, then the running time without interruption is increased, but the manufacturing costs increase
Solution Approach 1:
The patent segments the battery system into multiple smaller battery units instead of using one large high-capacity battery. These smaller batteries are cheaper to manufacture individually and can be produced using standard, cost-effective manufacturing processes, thereby reducing overall manufacturing costs while still achieving extended operational duration through multiple units.
Solution Approach 2:
The patent employs multiple smaller, more affordable battery units that can be individually replaced rather than using one expensive, large-capacity battery. The cost of manufacturing multiple smaller batteries is lower than a single large battery, and the system is designed to swap these shorter-lived, cheaper units to achieve the desired operational duration.
3Duration of action of moving object
If a battery with extraordinarily high capacity is used to extend operating time, then the running time without interruption is increased, but the robot becomes extraordinarily heavy and bulky
Solution Approach 1:
The patent divides the battery system into multiple smaller battery units distributed throughout the robot rather than using one large, heavy battery. This segmentation reduces the weight concentrated at any single location and allows for better weight distribution, maintaining robot maneuverability while achieving extended running time through multiple units.
Solution Approach 2:
Instead of increasing battery capacity in a single dimension (one large battery), the patent distributes battery capacity across multiple dimensions by using several smaller batteries positioned at different locations in the robot. This dimensional distribution achieves the same total energy capacity while reducing overall weight and improving the robot's spatial characteristics.
