Solution Overview
Problem
Current communication protocols for power tools are complex and lack a universal standard, making it difficult to enable seamless communication and data exchange across various power tool types and platforms, including those powered by different voltage sources.
Innovation Solution
A universal protocol system is implemented using a generic universal core module and interface modules specific to each tool type, enabling translation between different communication protocols and allowing for the retrieval of performance data and firmware installation across a variety of power tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a universal protocol system with core module and interface modules is implemented, then communication compatibility across different power tool types is improved, but device complexity increases due to multiple modules and translation layers
Solution Approach 1:
The communication system is divided into a universal core module that handles protocol translation and tool-specific interface modules that handle device-specific protocols. This segmentation allows the universal core to remain simple while supporting multiple tool types through modular interface additions.
Solution Approach 2:
The universal core module acts as an intermediary between tool-specific interface modules and the central controller. It translates communications between different protocols without requiring the controller to understand each specific protocol, simplifying the overall system architecture.
2Adaptability or versatility
If translation modules are added for each tool type, then communication versatility is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The universal core module provides multi-functional protocol translation capabilities that can handle multiple tool types through a single standardized interface. This eliminates the need to manufacture different controller versions for each tool type, reducing production complexity.
Solution Approach 2:
Tool-specific interface modules are nested within the universal core module architecture. Each interface module can be independently developed and integrated, allowing for modular manufacturing where the universal core remains constant while interface modules are added or modified as needed.
3Adaptability or versatility
If protocol translation layers are implemented, then data exchange capability across platforms is improved, but information loss or transmission errors may increase
Solution Approach 1:
The universal core module implements feedback mechanisms to verify successful protocol translation and data integrity. Error detection and correction protocols ensure that translations between different communication protocols maintain data reliability.

AI summary
A method for communicating between motorized power tools includes establishing, using a physical interface of a first power tool, a wireless radio link between the first power tool and a second power tool. The first power tool has a first motor and the second power tool has a second motor. A signal is received over the wireless radio link, via the physical interface, at the first power tool from the second power tool using a first wireless communication protocol. The signal includes an identifier. The second power tool is verified as authorized to send the signal to the first power tool based on the identifier. A tool component of the first power tool is controlled responsive to the signal.
