Problem

Existing warehouse management systems face inefficiencies in battery management and data transfer for mobile robots, particularly in scenarios where robots need to operate continuously without waiting for battery recharge and where data storage and transfer are cumbersome.

Innovation Solution

The implementation of exchangeable battery packs with rechargeable batteries and local data storage components, along with a battery exchange station equipped with multiple chargers and communication interfaces, allows robots to swap batteries and transfer data efficiently, enabling continuous operation and centralized data management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If mobile robots use rechargeable batteries with local data storage components, then continuous operation is enabled and centralized data management is achieved, but device complexity increases

Engineering Contradiction:
Improvecontinuous operation capabilityVSAvoidbattery pack structure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent combines the battery and local data storage component into a single integrated battery pack unit. This merging allows the robot to swap both power and data storage simultaneously, enabling continuous operation without separate recharging and data transfer steps, thus resolving the contradiction between productivity improvement and device complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The battery pack serves multiple functions: it provides electrical power to the robot and simultaneously stores sensor data locally. This multi-functionality reduces the need for separate components and interfaces, managing complexity while enabling continuous operation and centralized data management.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Loss of time

If battery exchange station implements simultaneous charging and data transfer, then operational downtime is reduced, but device complexity increases

Engineering Contradiction:
Improvebattery recharge waiting timeVSAvoidexchange station system complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The exchange station performs battery charging and data transfer simultaneously through parallel processing. While the battery is being recharged, the data is being transferred to centralized storage, eliminating sequential waiting time and reducing operational downtime despite increased system complexity.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The system prepares replacement battery packs in advance with pre-charged batteries and pre-cleared data storage components. This preliminary preparation allows robots to swap batteries instantly without waiting for charging or data transfer, significantly reducing operational downtime.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If robots transfer data wirelessly during operation, then operational flexibility is maintained, but wireless communication interference increases

Engineering Contradiction:
Improvedata transfer convenienceVSAvoidwireless communication interference
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The patent extracts data transfer from the wireless communication domain and relocates it to the physical domain through battery pack swapping. Data is transferred physically via the battery connection rather than wirelessly, eliminating communication interference while maintaining operational flexibility through quick battery exchanges.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The battery pack serves as an intermediary carrier for data storage and transfer. Instead of direct wireless communication between robot and centralized system, data is first stored locally in the battery pack's storage component, then transferred through the battery exchange station, mediating the data transfer process and eliminating wireless interference.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

An example method includes receiving, by a mobile robotic device, power from a battery of a first battery pack in order to operate within an environment. The method further includes establishing a first data channel between the mobile robotic device and the first battery pack. The method also includes using the first data channel to transfer sensor data acquired by the mobile robotic device during operation to a local data storage component of the first battery pack. The method additionally includes navigating, by the mobile robotic device, to a battery exchange station to transfer the first battery pack containing the battery and the local data storage component with the sensor data to the battery exchange station. The method further includes after transferring the first battery pack to the battery exchange station, receiving a second battery pack from the battery exchange station to continue operation within the environment.
