Power Tool Wireless Update via Shared Bus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power tool systems face inconvenience in software updates, requiring disassembly for changes, which hampers product development and user experience due to the lack of a convenient and quick software upgrading method.
Innovation Solution
A power tool system with a cloud server and IoT module enables wireless communication, allowing an upgrading file to be written and transmitted to control and driving modules via a shared bus, facilitating remote software updates even in unstable network conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional software update methods are used requiring physical disassembly, then software can be updated, but the update process becomes complex and time-consuming
Solution Approach 1:
The patent replaces the mechanical disassembly process with a wireless communication system. The IoT module establishes a wireless connection to receive update files, and the bus system electronically distributes these files to target modules, eliminating the need for physical opening and manual file transfer.
Solution Approach 2:
The patent introduces an IoT module as an intermediary component that handles wireless communication and file reception. This intermediary manages the entire update process from wireless file acquisition to internal distribution through the bus system, simplifying the user interface while managing complexity internally.
2Ease of operation
If wireless communication is implemented for software updates, then update convenience is improved, but network stability becomes a critical challenge
Solution Approach 1:
The patent implements a two-stage update process where the update file is first downloaded and stored in the IoT module's memory during network availability. The actual software update is then executed later when the device is operational, decoupling the file acquisition from the update execution and reducing network stability requirements.
Solution Approach 2:
The system automatically manages the update process including file reception, storage, validation, and distribution without requiring continuous network connection or user intervention. The IoT module and bus system handle the update execution autonomously once the file is received.
3Productivity
If upgrading files are transmitted to multiple modules simultaneously, then update efficiency is improved, but data transmission complexity increases
Solution Approach 1:
The patent segments the update file into multiple data packets and distributes them through the bus system to different target modules simultaneously. Each module receives and processes its designated portion independently, enabling parallel update operations across multiple components.
Solution Approach 2:
The bus system serves multiple functions: it acts as a communication backbone for data transmission, a distribution network for file allocation, and a coordination mechanism for simultaneous multi-module updates. This universal communication infrastructure handles both simple and complex update scenarios.

AI summary
A power tool system includes a power tool and a cloud sever configured to receive an upgrading file for upgrading the power tool. The power tool is adapted for wireless communication with the cloud server and includes a motor, a driving module for driving the motor, a control module for outputting a control signal to the driving module, and an IoT module for establishing a wireless communication link between the power tool and the cloud server. The IoT module, the driving module and control module share a bus, and the upgrading file is simultaneously distributed to the control module and/or the driving module through the bus.
