Electric Tool Voice Broadcast for Clear Status and Fault Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional electric tools rely on simple buzzers to indicate states like startup, shutdown, and faults, making it difficult for users to accurately determine the current state of the tool, especially for complex conditions like communication failures, battery mismatches, and temperature issues, requiring a more intuitive and humanized way to communicate these states.
Innovation Solution
An intelligent voice broadcast method is implemented in electric tools, featuring a state detection unit, voice broadcast unit, and voice conversion unit, which generates and broadcasts voice commands based on power supply and temperature information, providing clear voice alerts for various conditions, including low battery, overtemperature, and communication failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a traditional buzzer is used to prompt working states, then the device complexity is low and manufacturing cost is reduced, but the information transmission clarity deteriorates and user understanding becomes difficult
Solution Approach 1:
The patent replaces the traditional mechanical buzzer system with an electronic voice synthesis system. The control unit generates voice signals that are converted to audible speech through a voice module, substituting the simple electromagnetic buzzer mechanism with an electronic information processing system that can articulate complex state descriptions clearly.
Solution Approach 2:
The patent introduces a voice conversion module as an intermediary between the control unit and the output device. This module translates digital state information into human-readable voice prompts, serving as a mediator that converts raw data into comprehensible information, thereby improving information transmission without requiring complex user interpretation.
2Ease of operation
If simple buzzer sounds are used, then the manufacturing cost is reduced and ease of manufacture is improved, but the ease of operation deteriorates as users cannot easily understand tool states
Solution Approach 1:
The patent changes the output parameter from simple acoustic frequency (buzzer tone) to linguistic information (voice speech). By transforming the nature of the output signal from physical vibration characteristics to semantic content, the system provides intuitive state information that is immediately understandable to users, significantly improving ease of operation.
Solution Approach 2:
The patent replaces the mechanical buzzer system with an electronic voice synthesis system. The control unit generates voice signals that are converted to audible speech through a voice module, substituting the simple electromagnetic buzzer mechanism with an electronic information processing system that can articulate complex state descriptions clearly.
3Loss of time
If professional documentation is required to interpret buzzer sounds, then the device complexity remains low, but the loss of time increases as users need to reference manuals
Solution Approach 1:
The patent implements a self-service information system where the electric tool itself provides the explanation of its state through voice prompts. Instead of requiring users to externally reference manuals or documentation, the system autonomously communicates its status, diagnostics, and operational state directly to the user, eliminating the need for external reference materials and reducing time loss.
Solution Approach 2:
The patent establishes a feedback loop where the control unit continuously monitors tool state and immediately communicates changes back to the user through voice prompts. This real-time feedback mechanism provides instantaneous information about operational status, errors, and warnings, eliminating the delay associated with manual documentation lookup and enabling users to respond promptly to tool conditions.
