Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a table type interface is used for setting timing switch operations, then the setting process can be completed, but the operator cannot intuitively recognize the positional relation between slide motion and attachment device operation
Solution Approach 1:
The patent transforms the conventional table-type interface into a circular graphical interface where the slide motion is represented as rotational motion of the eccentric mechanism. This dimensional change from tabular data to circular visualization allows operators to intuitively understand the positional relationship between slide position and attachment device operation timing through visual feedback on the circular display.
Solution Approach 2:
The patent creates a visual copy of the eccentric mechanism's rotational motion on the display unit. By showing a circular image that replicates the actual mechanical rotation and overlaying attachment device operation positions on this circular representation, operators can visually comprehend the timing and positional relationships without relying on abstract numerical tables.
2Adaptability or versatility
If numerical values are input to a table interface, then the operation settings can be configured, but the setting accuracy depends on operator skill and imagination
Solution Approach 1:
The patent implements visual feedback by displaying the eccentric mechanism's rotational position and attachment device operation positions on a circular image. As operators input settings, the system visually confirms the positional relationships on the circular display, allowing operators to verify and adjust settings for accurate timing without relying solely on numerical input and personal imagination.
Solution Approach 2:
The patent changes the setting interface from a two-dimensional table to a circular graphical representation that mirrors the actual rotational motion of the eccentric mechanism. This dimensional transformation allows operators to visually perceive the timing and positional relationships, improving setting precision while maintaining the flexibility to configure various operation parameters.
3Ease of operation
If conventional table interface is used, then settings can be made, but different settings may result from operator imagination rather than intended operation
Solution Approach 1:
The patent creates a visual copy of the actual eccentric mechanism rotation on the display unit, showing the rotational position and attachment device operation positions in a circular format. This visual representation eliminates the ambiguity of table interfaces by directly displaying the spatial and temporal relationships, ensuring that settings match the operator's intended operation rather than relying on subjective imagination.
Solution Approach 2:
The system provides real-time visual feedback on the circular display as operators configure settings. The display shows the actual positional relationships between slide motion and attachment device operation, allowing operators to verify their settings and make corrections, thereby ensuring reliable and accurate configuration that matches operational intentions.

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.
