Voice Control for Mobile Construction Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile construction machines are complex to operate, requiring both hands and often necessitate stopping to perform additional functions, and managing data from these machines across multiple remote server locations is cumbersome, leading to high computing overhead and bandwidth requirements.
Innovation Solution
A mobile construction machine equipped with speech processing capabilities that detects speech triggers to generate control signals, allowing for hands-free operation and centralized data management through speech recognition, natural language understanding, and synthesis, enabling control of the machine, other machines, or remote servers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional manual control methods are used for mobile construction machines, then the operator can directly control the machine, but the operator requires both hands to operate and must stop the machine to perform additional functions
Solution Approach 1:
The patent replaces manual mechanical control operations with voice-based acoustic control. The speech processing system captures voice commands from the operator, processes them through speech recognition and natural language understanding, and converts them into control signals that operate the construction machine. This substitution allows hands-free operation while managing control complexity through automated speech processing algorithms.
2Loss of information
If data from multiple remote server locations is accessed separately, then complete information can be obtained, but the process is cumbersome and requires high computing overhead and bandwidth
Solution Approach 1:
The patent merges data access operations from multiple remote server locations into a single unified speech command. The speech processing system interprets commands like 'aggregate data from all servers' and automatically coordinates with multiple servers to retrieve and combine information. This consolidation reduces the operational complexity of accessing distributed data while maintaining complete information aggregation across all server locations.
3Productivity
If the machine stops to perform additional functions, then subsystems can be activated, but operational time is lost and productivity decreases
Solution Approach 1:
The patent enables continuous operation of the construction machine by allowing voice-activated control during movement. The speech processing system processes commands in real-time while the machine is in motion, enabling the operator to activate subsystems, adjust settings, or request data aggregation without stopping. This maintains continuous productive action while preserving operational flexibility through hands-free voice control.
Data Source
AI summary
A mobile construction machine detects a speech processing trigger. It then performs speech processing (such as speech recognition and natural language understanding, speech synthesis, etc.) based on the detected speech processing trigger, to generate a speech processing result. A control signal generator generates control signals based on the speech processing result. The control signals can be used to control the mobile construction machine, to control another mobile construction machine, to provide information to a remote server location, or to aggregate information from multiple remote server locations.
