Power Tool Firmware Relay Across Different Subnets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication methods for power tools require separate login for each tool and necessitate identical tools in the same subnet, limiting convenience and universality.
Innovation Solution
A power tool system with different devices communicating via distinct communication modules, allowing firmware upgrades through Bluetooth networking or data transmission links, enabling upgrades across devices in different subnets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate login is required for each portable tool to establish communication connection with the network host server, then security and device identification are improved, but operation complexity and time consumption increase significantly
Solution Approach 1:
The patent merges multiple separate login operations into a single login action. When a user logs in to one portable tool, the system automatically establishes communication connections with other portable tools in the same subnet, eliminating the need for repeated logins and significantly reducing operation complexity while maintaining device identification reliability
2Reliability
If portable tools must be identical and located in the same subnet to achieve wireless communication, then network security and communication stability are improved, but adaptability and universality deteriorate
Solution Approach 1:
The patent implements a universal communication mechanism where a single portable tool can act as a relay for other tools in the same subnet. This allows firmware upgrades and data transmission across diverse tool types without requiring each tool to directly connect to the network host server, thereby enhancing adaptability and universality while maintaining communication stability through subnet-based authentication
3Reliability
If each portable tool establishes separate communication connections with the network host server, then device independence and network security are improved, but system complexity and communication overhead increase
Solution Approach 1:
The patent introduces a intermediary mechanism where one portable tool serves as a relay station for firmware transmission to other tools in the subnet. This reduces the number of direct connections required to the network host server, simplifying the system architecture while maintaining network security through the existing authentication framework

AI summary
A power tool system includes a first device and a second device, where the first device is different from the second device, and the first device is configured to download, from a remote device through a first communication module, an upgrade package applicable to the second device, store the upgrade package into a memory, and transmit the upgrade package to the second device through a second communication module.
