Voice-Guided Machine Dimension Adjustment for Error-Prone Changeovers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Changing dimensions on industrial machines is a laborious and error-prone process for operators, who must perform numerous manual adjustments based on written instructions, leading to potential misreads and miswrites, resulting in poor product quality.
Innovation Solution
A method using a portable device with voice recognition and synthesis capabilities connected to a remote server, allowing operators to request assistance through voice commands, with relevant data being selected and audio signals provided for adjustments, checks, and encoding procedures, simplifying and securing the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustments are performed based on written instructions, then the operator can follow step-by-step procedures, but the process becomes laborious and error-prone due to numerous manual operations
Solution Approach 1:
The patent replaces the mechanical system of manual reading and writing with an acoustic system using voice recognition and voice synthesis. The operator speaks requests instead of reading written instructions, and receives audio responses instead of reading text, thereby reducing manual operations while maintaining procedural guidance
Solution Approach 2:
The system enables the operator to independently obtain adjustment information through voice commands without requiring manual consultation of written procedures. The voice recognition system processes the operator's spoken requests and retrieves relevant adjustment data automatically, making the operator self-sufficient in performing adjustments
2Manufacturing precision
If numerous manual adjustments are performed, then complete dimension changes can be achieved, but misreads and miswrites occur leading to poor product quality
Solution Approach 1:
The patent eliminates the mechanical processes of reading and writing by substituting them with voice-based interaction. Voice recognition captures the operator's requests accurately, and voice synthesis delivers adjustment information without the errors associated with manual reading and writing, thereby improving both manufacturing precision and reliability
Solution Approach 2:
The system incorporates feedback mechanisms where the operator's voice requests are processed and confirmed through audio responses. This closed-loop communication ensures that the correct adjustment information is transmitted and understood, reducing errors and improving the reliability of the adjustment process
3Ease of operation
If voice recognition and synthesis systems are implemented, then manual operations are reduced and accuracy improves, but device complexity increases
Solution Approach 1:
The patent introduces voice recognition and voice synthesis systems as intermediary components between the operator and the adjustment process. These intermediaries handle the complex tasks of speech processing and information retrieval, allowing the operator to interact simply through natural speech while the complex processing occurs in the background

AI summary
A method for assisting in adjusting the dimensions of an industrial machine, the machine being driven by an operator provided with a portable device that is provided with a microphone and with a speaker, the device being connected to a remote server hosting a database and software means, comprises the following steps: The operator transmits, via the microphone, a voice request for assistance in relation to a step in a procedure for adjusting the dimensions of the machine, the request is analysed by voice recognition means, on the basis of the request, a set of data relevant to the step to be performed is selected from the database, the relevant data are converted into an audio signal understandable to the operator, via voice synthesis means, and the audio signal is transmitted to the operator via the speaker.
