Solution Overview

Problem

Rechargeable electric tools with small power are inadequate for high-power applications, and tools with heavy batteries are difficult to carry, while plug-in electric tools are limited to power supply and not suitable for outdoor use.

Innovation Solution

A mobile power supply device with a large capacity battery, driving device, and tracking system that automatically follows the user, eliminating the need for batteries in electric tools and allowing high-power tools to be used outdoors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If a high-power electric tool is used, then the power is sufficient for outdoor work, but the battery becomes heavy and difficult to carry

Engineering Contradiction:
ImprovepowerVSAvoidbattery weight
Core Design Contradiction:
PowerVSWeight of moving object

Solution Approach 1:

The power supply system is segmented into two parts: a large-capacity battery pack housed in a mobile power supply device and a lightweight electric tool. The battery pack (600-1000Wh) remains in the mobile device while the tool operates with minimal battery or no battery, separating the heavy power source from the lightweight tool to resolve the contradiction between high power and portability

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A mobile power supply device with automatic tracking function serves as an intermediary between the power source and the user. The device follows the user automatically using tracking technology (GPS, Bluetooth, or visual tracking), providing power through wireless transmission or proximity coupling, thus eliminating the need for the user to carry heavy batteries while ensuring continuous power supply for high-power tools

Inventive Principle:
Principle #24Intermediary (Mediator)

2Power

If plug-in electric tools are used, then high power is available, but they are limited to power supply and cannot be used outdoors

Engineering Contradiction:
ImprovepowerVSAvoidoutdoor usability
Core Design Contradiction:
PowerVSAdaptability or versatility

Solution Approach 1:

The mobile power supply device is designed as a universal platform that combines multiple functions: it serves as a large-capacity power source, an automatic tracking follower, and an outdoor mobile station. The device can adapt to various outdoor scenarios (forestry, agriculture, construction) and work with different electric tools, providing both high power and outdoor versatility through its multi-functional design

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

Solution Approach 2:

The mobile power supply device performs self-service through automatic tracking functionality. It autonomously follows the user without manual control, automatically positioning itself to provide power. This self-service capability enables outdoor usability by eliminating the need for manual power source management, making the system as adaptable and convenient as plug-in tools but with outdoor mobility

Inventive Principle:
Principle #25Self-service

3Weight of moving object

If rechargeable electric tools with small power are used, then they are lightweight and easy to carry, but they are inadequate for high-power applications

Engineering Contradiction:
Improvetool weightVSAvoidpower
Core Design Contradiction:
Weight of moving objectVSPower

Solution Approach 1:

The system segments the power supply function from the tool itself. The electric tool is designed to be lightweight by removing or minimizing its battery, while the heavy lifting power supply function is segregated into a separate mobile power supply device. This segmentation allows the tool to remain lightweight and easy to carry while accessing high power when needed by connecting to the mobile power supply

Inventive Principle:
Principle #1Segmentation

AI summary

A mobile power for outdoor power supply includes a power housing, a battery pack, a driving device, a controller and a tracking device. The battery pack is disposed inside the power housing. The power housing is provided with at least one socket electrically connected with the battery pack. The battery pack is used to supply electric power to an electric tool during outdoor work through the socket. The driving device includes wheels and driving motors for driving the wheels. The controller is connected with the driving motors. The tracking device is connected with the controller. The tracking device is used to track the user of the mobile power. The controller controls the driving device to drive the power housing to automatically follow the user according to the tracking result of the tracking device. The mobile power is suitable for power supply for high-power electric tools during outdoor work.
