Wireless Firmware Update for Portable Tools via Master Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for wireless communication between a web host server and portable tools are time-consuming and complex, particularly for uploading firmware updates, as operators must establish separate connections for each tool.
Innovation Solution
A method that enables wireless communication between a web host server and multiple portable tools within the same subnet, allowing for simultaneous firmware updates without individual login requirements, using a web host server and an access point server to manage communication links and data transmission via TCP/IP protocol, with encryption for secure data exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate login and connection establishment is performed for each portable tool, then individual tool control and security are ensured, but the time consumption and operational complexity increase significantly
Solution Approach 1:
The system segments the authentication process by introducing a master device that handles centralized authentication for multiple portable tools. Each tool retains individual identification and control capabilities, but the authentication overhead is segmented away from individual tool operations and consolidated at the master device level.
Solution Approach 2:
The master device acts as an intermediary between the user and multiple portable tools. It establishes a single communication connection that mediates access to multiple tools, eliminating the need for separate login procedures while maintaining individual tool control through the intermediary's coordination.
2Reliability
If separate communication connections are established for each portable tool, then individual tool communication is secured, but the device complexity and operational difficulty increase
Solution Approach 1:
Multiple individual communication connections are merged into a single communication channel through the master device. The master device consolidates the connection management for multiple portable tools, reducing the number of active connections from N (one per tool) to 1 (through master device), while maintaining security through centralized control.
Solution Approach 2:
The master device serves multiple functions: it acts as an authentication server, a communication relay, and a control coordinator for multiple portable tools. This multi-functional approach eliminates the need for separate dedicated connection management for each tool, simplifying the overall system architecture.
3Measurement precision
If individual login is required for each portable tool, then precise tool identification and control are achieved, but the ease of operation deteriorates
Solution Approach 1:
The system implements self-service authentication where the master device automatically identifies and manages connections to multiple portable tools without requiring manual login for each tool. The tools present themselves through their unique identifiers, and the master device handles the authentication automation, maintaining precision while improving ease of operation.

AI summary
The invention relates to a method for wireless communication between a web host server and at least two portable tools, each of which comprises means for wireless communication as well as a data storage device and a tool control device, wherein communication data, in particular a firmware update, is transferred to each of the portable tools via the web host server, and wherein the portable tools are in communication connection with the web host server and/or with each other within the same subnetwork.
