Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous travel devices face challenges in rapid battery replacement and stabilization due to the weight and center of gravity issues associated with large-capacity batteries, which affect the stability of autonomous travel.
Innovation Solution
The autonomous travel device is designed with a power source located on one end and a battery accommodation unit from the other end to the central portion, allowing for easy battery replacement and stabilization by considering the center of gravity, featuring a structure with electric motors, transmissions, and a control device for autonomous travel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a large-capacity battery is used to increase power supply capacity, then the power supply duration is extended, but the battery weight increases and replacement time increases
Solution Approach 1:
The battery is divided into a battery pack (removable unit) and a battery holder (fixed unit). The battery pack can be quickly replaced without replacing the entire battery system, enabling rapid exchange while maintaining adequate power capacity in the retained holder.
Solution Approach 2:
The heavy battery pack is extracted as a separate removable component from the device main body. This allows the power supply function to be maintained through the battery holder while the heavy pack can be quickly swapped out, reducing overall system weight during operation.
2Duration of action of moving object
If a large-capacity battery is used to extend operation time, then the power supply capacity is increased, but the replacement time is extended
Solution Approach 1:
The battery system is segmented into a removable battery pack and a fixed battery holder. This allows rapid replacement of only the depleted pack while retaining the holder and any remaining charge, dramatically reducing replacement time compared to replacing an entire large battery.
Solution Approach 2:
The battery holder is pre-configured with terminals and mounting structures that enable quick connection. The separable design allows operators to have replacement packs ready, enabling rapid exchange without complex disassembly procedures.
3Stability of the object's composition
If the battery is disposed to optimize center of gravity, then the autonomous travel stability is improved, but the battery replacement complexity increases
Solution Approach 1:
The battery system is divided into a removable pack and a fixed holder mounted at the center of gravity position. This segmentation allows the holder to be strategically positioned for stability while the pack can be easily accessed and replaced from the rear opening, decoupling the stability requirement from replacement complexity.
Solution Approach 2:
The battery pack is extracted as a removable unit that can be accessed from the rear of the device. This allows the heavy battery to be positioned at the center of gravity for stability while the replacement operation can be performed from a convenient access point rather than requiring disassembly of the entire device.
4Reliability
If the entire battery is replaced to ensure power supply, then the power reliability is maintained, but the replacement time is extended
Solution Approach 1:
The battery system is segmented into a removable pack and a fixed holder. This allows rapid replacement of only the depleted pack while retaining the holder and any remaining charge, dramatically reducing replacement time compared to replacing an entire large battery while maintaining power supply reliability.
Solution Approach 2:
The battery pack is designed as a self-contained unit with all necessary terminals and connections. This local completeness allows the pack to be replaced independently without affecting the holder or other system components, enabling rapid replacement while ensuring reliable power connection.

AI summary
An autonomous travel device is provided with wheels, a device main body, a power source that is provided on one end portion of the device main body within the device main body and causes the device main body to travel autonomously by driving the wheels, a battery for supplying power to the power source, and an accommodation unit for accommodating the battery from the other end portion of the device main body to a central portion of the device main body within the device main body. With this configuration, it is possible to easily perform replacement of the battery, and therefore, it is possible to perform autonomous travel that is stabilized due to disposition of the battery in consideration of the center of gravity of the device main body.
