Solution Overview

Problem

In numerical control type machine tools, the operational efficiency of inputting processing information is hindered by the difficulty in locating and using input support buttons, leading to human errors and suboptimal measurement selection methods.

Innovation Solution

A control device with a display part that shows input screens for processing information, including input support buttons to guide users through the input process, and a measurement tool information acquiring part to facilitate accurate measurement and data input, reducing errors by displaying warning messages for invalid inputs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If input support buttons are provided on the input screen, then input guidance and measurement assistance are improved, but the complexity of the interface and difficulty of locating buttons worsen

Engineering Contradiction:
Improveinput guidanceVSAvoidinterface complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The input screen is divided into multiple functional areas with distinct buttons for different input methods (manual input, measurement tool input, file import, etc.). Each button is segmented to perform a specific function, making it easier for users to locate and use the appropriate input method without being overwhelmed by a monolithic interface.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The control device introduces an intermediary processing layer that manages the complexity of multiple input methods. When a button is pressed, the control device mediates between the user's simple action and the complex underlying processes (coordinate system selection, measurement tool calibration, data processing), shielding users from complexity while providing comprehensive input support.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple measurement methods are available, then measurement flexibility and adaptability are improved, but the difficulty of selecting the optimal method and potential for human error worsen

Engineering Contradiction:
Improvemeasurement method selectionVSAvoidinput accuracy
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The control device provides feedback mechanisms that guide users in selecting the optimal measurement method. The system analyzes the current context (workpiece type, tool configuration, processing requirements) and provides feedback through the interface to recommend or automatically select the most appropriate measurement method, reducing human error while maintaining versatility.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The control device performs preliminary analysis and preparation before the actual measurement process. It pre-configures measurement parameters, pre-selects appropriate measurement methods based on stored data about similar workpieces, and prepares the measurement tools in advance, allowing users to benefit from optimized selections without having to manually determine the best approach.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If manual input of processing information is required, then flexibility in data entry is improved, but the time consumption and productivity worsen

Engineering Contradiction:
Improvedata entry flexibilityVSAvoidinput efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The control device provides a dynamic input system that adapts to user needs in real-time. The interface can switch between different input modes (manual keyboard input, measurement tool automatic input, file import, voice input) depending on the situation. This dynamic adaptability allows users to choose the most efficient method for each specific task, maintaining flexibility while significantly improving overall productivity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The control device implements a universal input interface that can handle multiple types of data entry through a unified system. The same interface supports manual input, automatic measurement tool integration, file imports, and other methods, allowing users to leverage different input methods within a single flexible framework rather than requiring separate systems for each input type.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

This control device (70) for a machine tool (11) has a display unit (28) that displays an input screen via which machining information regarding machining to be performed on a workpiece is inputted and an input unit via which letters and/or numbers are inputted into machining-information fields on the input screen. When a machining-information field on the input screen is selected, the display unit (28) displays a first input-assistance screen corresponding to said field. Input-support buttons are laid out on said first input-assistance screen. When an input-support button is pressed, a second input-assistance screen is displayed, and via an operation performed in accordance with said second input-assistance screen, the aforementioned field is filled in.
