Adjusting Device for Operating Machines Change Confirmation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the number of adjustment items in work machines increases, operators face difficulties in determining which items have been changed, leading to potential omissions and errors during adjustment processes.
Innovation Solution
An adjusting device with a control section, input section, and display section that stores item IDs and adjustment values, allowing operators to easily confirm changes by indicating the ID and value of adjusted items, with options to store last values or change flags to differentiate changed items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of adjustment items is increased to provide more functions, then the functionality and versatility of the work machine is improved, but the operator's ability to determine changed items deteriorates, leading to omissions and errors
Solution Approach 1:
The control section provides feedback by indicating on the display section which adjustment items have been changed and what their new values are. This feedback mechanism allows operators to confirm changes immediately after execution, preventing omissions and errors even when dealing with a large number of adjustment items.
Solution Approach 2:
The display section acts as an intermediary between the control section and the operator. It visually presents the changed adjustment items and their values, serving as a communication bridge that ensures accurate information transfer and confirmation.
2Adaptability or versatility
If the number of adjustment items is increased, then the versatility of the work machine is improved, but the complexity of tracking and confirming changes increases
Solution Approach 1:
The system extracts and highlights only the changed adjustment items for display, separating them from the unchanged items. This extraction approach simplifies the operator's task by presenting only the relevant information that requires attention, rather than requiring tracking of all adjustment items.
Solution Approach 2:
The display section visually distinguishes changed adjustment items from unchanged ones through visual indication. This visual differentiation makes it easy for operators to identify which items have been modified, reducing the cognitive load and complexity of change tracking.
3Device complexity
If traditional adjustment methods are used without change indication, then the device simplicity is maintained, but the ease of operation deteriorates due to difficulty in confirming changes
Solution Approach 1:
The system automatically provides change information without requiring additional manual confirmation steps from the operator. The control section autonomously identifies and displays changed items, making the confirmation process self-service and eliminating the need for complex manual verification procedures.

AI summary
Provided is an adjusting device for operating machines which facilitates the work of confirming a changed adjustment item. The adjusting device for operating machines is equipped with: a control unit (50); input units (41)-(46) connected to the control unit (50); and a display unit (47) connected to the control unit (50). The control unit (50) stores the item ID and adjustment value of each of a plurality of adjustment items. Upon receiving a change operation, the control unit (50) changes the adjustment value of a specified adjustment item to a specified value. Upon receiving a change end operation, the control unit (50) displays, on the display unit (47), the item ID and the adjustment value corresponding to the adjustment item with the adjustment value changed. Since the changed adjustment item is displayed after the end of the change operation, the confirmation work is facilitated. Therefore, change omissions or errors can be reduced.
