Rotating Workpiece Holder for Cutting Machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting machines make it difficult for users to manually replace workpieces due to varying user heights, which can obstruct the view of the workpiece held by the holding device.
Innovation Solution
A cutting machine design that includes a holding device, a case body with a side-opening area, a rotation device, and a control device. The control device features a rotation controller that adjusts the holding device's orientation by a predetermined angle when the user replaces the workpiece, allowing for easier manual replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the holding device maintains a fixed orientation, then the structure is simple, but users with different heights cannot easily view and replace workpieces
Solution Approach 1:
The holding device is made rotatable around the axis line, transforming from a fixed orientation to a dynamic adjustable orientation. The rotation device enables the holding device to rotate to different angles, allowing users with different heights to easily view and replace workpieces while maintaining operational simplicity
Solution Approach 2:
The holding device is designed to serve multiple users with different heights by enabling rotation to multiple predetermined angles. This multi-functional capability allows the same device to accommodate various user needs without requiring separate devices for different height requirements
2Ease of operation
If the holding device is rotated to multiple orientations, then user accessibility is improved, but the control system becomes more complex
Solution Approach 1:
The rotation device is configured to rotate the holding device to predetermined angles in advance, based on different user height requirements. The control device stores multiple predetermined rotation angles and automatically selects and executes the appropriate angle, eliminating the need for complex real-time calculations or manual adjustments during workpiece replacement
Solution Approach 2:
The system changes the rotation angle parameter of the holding device to predetermined values based on user height. By discretizing the rotation angle into specific predetermined values rather than allowing continuous adjustment, the control system remains simple while still providing multiple orientation options for different users

AI summary
A cutting machine includes a holding device that holds a workpiece, a case body in which an area in which the holding device is stored and an opening portion that communicates with the area are formed, a rotation device that rotates the holding device around an axis line that extends in a second direction that is orthogonal to a first direction when viewed from top, and a control device. The holding device is configured to hold the workpiece by moving the workpiece in a holding direction toward the holding device by a user. The control device includes a rotation controller that rotates, when the user replaces the workpiece held by the holding device, the holding device around the axis line such that the holding device is placed to be in a rotation orientation achieved by rotating the holding direction from the first direction only by a predetermined rotation angle.
