Machine Tool Voice Interface for Context-Aware Screen Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial robots lack efficient speech-based interfaces for operators to navigate and control machine tools, leading to difficulties in selecting the correct screens for specific operating statuses, especially for inexperienced users and in scenarios with numerous similar screens.
Innovation Solution
A machine tool system incorporating a speech input unit, speech recognition unit, status determination unit, screen selection unit, and learning unit that recognizes operator speech, determines the machine's operating status, and selects the appropriate screen for display, allowing operators to use natural language to access desired functions, with a learning mechanism to improve accuracy over time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional manual navigation methods are used to select screens, then system complexity remains manageable, but operator ease of operation deteriorates due to difficulty in navigating numerous similar screens
Solution Approach 1:
The patent replaces manual navigation through graphical user interfaces with speech recognition technology. Operators speak natural language commands to select screens and functions, eliminating the need to manually navigate through multiple similar screens. The speech recognition unit processes vocal inputs and converts them into system commands, significantly improving ease of operation while the system manages the complexity internally.
2Ease of operation
If speech recognition is implemented without considering operating status, then interface simplicity improves, but measurement precision deteriorates due to inability to distinguish context-specific screen requirements
Solution Approach 1:
The patent incorporates a status determination unit that continuously monitors the machine tool's operating status and provides feedback to the screen selection process. When an operator speaks a command, the system combines the speech recognition results with the current operating status to accurately determine which screen should be displayed. This feedback mechanism ensures that the same speech command can lead to different screen selections depending on the machine's state, thereby maintaining high precision in screen selection while preserving interface simplicity.
3Adaptability or versatility
If multiple screens with similar functions are provided, then system versatility improves, but ease of operation deteriorates due to difficulty in selecting the correct screen
Solution Approach 1:
The patent implements a universal speech-based interface that can handle multiple similar functions through a single command structure. Instead of requiring operators to navigate to different screens for similar functions, the speech recognition system interprets natural language commands and routes them to the appropriate functions regardless of which screen they are currently on. This multi-functional approach maintains system versatility while dramatically improving ease of operation, as operators can access any function through speech without needing to know which specific screen contains it.

AI summary
A machine tool includes a speech input unit that accepts speech from an operator as input, a speech recognition unit that recognizes the speech input into the speech input unit, a status determination unit that determines an operating status of the machine tool when the speech is input into the speech input unit, a display unit, a storage unit that stores a plurality of screens, and a screen selection unit that selects a screen according to a combination of the speech recognized by the speech recognition unit and the operating status of the machine tool determined by the status determination unit from among the plurality of screens, and causes the display unit to display the selected screen.
