Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators find it difficult to intuitively set the positional relation between slide motion and the operation of attachment devices in press machines, leading to incorrect settings due to reliance on imagination rather than visual feedback.
Innovation Solution
A press machine with a display unit showing a circular image representing slide operation and a concentric circular-arc image for attachment device operation, allowing operators to visually set and understand the relation between slide motion and attachment device operations through interactive input on a touch panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a table type interface is used for setting timing switch parameters, then the setting process can be completed, but the operator cannot intuitively understand the positional relation between slide motion and attachment device operation
Solution Approach 1:
The patent creates a visual copy of the eccentric mechanism's rotational trajectory as a circular image, where the slide operation region and attachment device operation region are displayed as concentric circular arcs. This graphical representation copies the actual motion paths and allows operators to visually set timing parameters by directly manipulating the displayed arcs, eliminating the need to mentally imagine the positional relationships that were previously lost in tabular data entry.
2Reliability
If conventional table type interface is used, then setting can be performed, but different settings may result due to operator's imagination rather than visual feedback
Solution Approach 1:
The patent implements visual feedback by displaying the slide operation region and attachment device operation region as concentric circular arcs on the screen. When operators adjust timing parameters, they can immediately see how the circular arcs change position and overlap, providing real-time visual feedback that confirms the correctness of their settings. This eliminates the reliability issues caused by relying on imagination without visual confirmation.
3Ease of operation
If numerical value input method is used, then settings can be entered, but operators require higher level skill to correctly imagine slide motion
Solution Approach 1:
The patent transforms the one-dimensional numerical parameter input into a two-dimensional visual interface. Instead of entering numbers that represent crank angles or timing values, operators interact with circular arcs that visually represent the actual motion paths of the slide and attachment devices. This dimensional transformation from numerical to graphical representation eliminates the need for operators to mentally visualize motion, making the system easier to operate regardless of skill level.
Applied Scientific Principles

Function Achieved in This Case
Enables operators to easily and accurately set attachment device operations by visually recognizing the relation between slide motion and attachment device operations, reducing errors and increasing operability.
Implementation Method 1
a press machine performing press working by transforming a rotation of an electric motor into a reciprocating linear motion of a slide by using an eccentric mechanism which transforms a rotational motion into a linear motion

AI summary
A press machine includes a display unit which displays a first image in a circular shape corresponding to a rotation of an eccentric mechanism and representing one stroke of slide operation and a second image in a circular-arc shape corresponding to an operation of an attachment device interlocked with the press machine, and an operation unit which receives an input operation. The first image indicates at least one slide operation region. The second image is placed concentrically with the first image in relation to the slide operation region. The second image has opposed ends each allowed to move in response to the input operation in a direction in which the second image extends.
