Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power tools lack a practical method to retrieve and display operational data, as incorporating large output devices increases weight and complexity, making it difficult for operators and maintenance personnel to access internal state data, especially in handheld tools.
Innovation Solution
A power tool data communication system that includes a housing with a memory for storing operational parameters, a wireless transceiver for data transmission, and a controller to identify and store data, allowing for wireless communication with external devices, enabling the retrieval of operational parameters without adding weight or complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If LCD displays or other output devices are incorporated to display operational state data, then operators can view internal operating state data, but the weight and complexity of the power tool increase
Solution Approach 1:
The patent extracts the output device from the power tool itself and places it in a separate external device. The power tool only contains a wireless transceiver to transmit operational state data, while the display and user interface are located in the external device held by the operator. This separation resolves the contradiction by providing data access functionality without adding the weight and complexity of display hardware to the power tool.
Solution Approach 2:
The patent introduces a wireless communication system as an intermediary between the power tool and the external display device. The operational state data flows from the power tool through wireless transmission to the external device, eliminating the need for direct physical connection or integrated display hardware in the power tool. This intermediary approach enables data access while maintaining the simplicity and light weight of the power tool.
2Loss of information
If LCD displays or other output devices are incorporated to display operational state data, then operators can view internal operating state data, but the size of the power tool increases
Solution Approach 1:
The patent removes the display output device from the power tool and relocates it to an external device. This extraction eliminates the volume occupied by display hardware, buttons, and related components within the power tool, thereby maintaining a compact size suitable for handheld operation while still enabling operators to view operational state data on the external device.
3Loss of information
If complex output devices are incorporated, then operational state data can be displayed, but the power tool may fail in harsh working environments
Solution Approach 1:
The patent extracts the complex output device from the power tool environment and places it in a separate external device that the operator holds. This separation protects the power tool's internal components from potential damage while still providing data access functionality in the external device, thereby improving reliability in harsh working environments.

Data Source
AI summary
A power tool data collection system includes a memory in a housing of a power tool that stores data corresponding to at least one operational parameter of the power tool, a wireless data transceiver communicatively connected to the memory, and a controller operatively connect to the memory. The wireless data transceiver transmits the data corresponding to the at least one operational parameter of the power tool to an external wireless transceiver in response to receiving a signal from the external wireless transceiver. The controller identifies the at least one operational parameter of the power tool during operation of the power tool and stores the data corresponding to the at least one operational parameter in the memory to enable the wireless data transceiver to transmit the data.
