Material Testing Machine Voice Control for Gloved Operators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing material testing machines require operators to perform manual operations on input devices like button switches and touch panels, which can be difficult when hands are occupied or when wearing gloves, reducing operator workability.
Innovation Solution
Incorporating voice recognition technology to receive commands, extract specific words, and output instruction information to the testing machine or analyzer, allowing operators to provide instructions via voice input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation on button switches and touch panels is used, then the machine can be operated with simple input devices, but operator workability deteriorates when hands are occupied or gloves are worn
Solution Approach 1:
The patent replaces the mechanical operation input device (button switches and touch panels) with a voice recognition system. The voice receiving portion captures audio signals, the extraction portion identifies specific words through voice recognition processing, and the instruction portion converts these into operational commands for the material testing machine. This substitution eliminates the need for manual physical interaction with the operation input device, allowing operators to control the machine using voice commands even when hands are occupied or wearing gloves.
2Ease of operation
If voice recognition technology is implemented, then operator workability improves through hands-free operation, but device complexity increases
Solution Approach 1:
The control portion of the material testing machine is designed to perform multiple functions: it not only controls the testing operations but also incorporates voice recognition processing capabilities. The voice receiving portion, extraction portion, and instruction portion are integrated into the existing control architecture, allowing the control portion to handle both traditional operational control and voice-based commands. This multi-functionality approach adds hands-free operation capability without requiring a completely separate voice recognition system.
3Reliability
If voice commands are used for operation, then operator safety improves during test preparation, but response time may be affected
Solution Approach 1:
The voice recognition system is configured to continuously monitor and process voice commands during test preparation phases. By having the voice receiving portion actively listening and the extraction portion ready to identify specific words, the system can immediately respond to operator commands without requiring manual interaction setup. This preliminary preparation of the voice recognition system ensures that safety-critical operations can be commanded instantly via voice, maintaining rapid response times while improving operator safety during heavy object handling.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances operator workability by enabling hands-free operation and improving safety during test preparation, as operators can provide instructions remotely, especially when handling heavy objects.
Implementation Method 1
a voice receiving portion that receives a voice from a user, an extraction portion that extracts a specific word from the voice by voice recognition processing

AI summary
A tensile tester includes a tester main body that executes a material test, an association storage portion that stores a specific word and instruction information to the tester main body in association with each other, a voice receiving portion that receives a voice from a user, an extraction portion that extracts the specific word from the voice by voice recognition processing, a determination portion that determines, with reference to the association storage portion, the instruction information corresponding to the specific word extracted by the extraction portion, and an instruction portion that outputs, to the tester main body, the instruction information determined by the determination portion.
