Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
It is difficult to recognize whether a workpiece is properly attached to the holding portion of a cutting machine, making it challenging to ensure accurate positioning during the cutting process.
Innovation Solution
A cutting machine with a holding device that includes a first arm and a second arm, where a workpiece is sandwiched between them, and an adapter with projecting portions that interact with movable holding portions to ensure proper attachment by applying a pressing force when the workpiece passes a middle position, facilitating easy recognition of correct positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple holding structure is used, then the device complexity is reduced, but it becomes difficult to recognize whether the workpiece is properly attached
Solution Approach 1:
The patent uses visual indicators (color changes or position changes of indicators) on the holding device to show whether the workpiece is properly attached. When the workpiece is correctly positioned, the indicator displays a specific state that is easily visible to the operator, solving the detection difficulty without adding complex sensing systems.
Solution Approach 2:
The holding device automatically provides attachment status information through its own structure. The indicator mechanism is integrated into the holding device itself, which self-indicates the attachment state through mechanical position or visual feedback, eliminating the need for external detection systems.
2Device complexity
If no guiding mechanism is provided, then the device complexity is reduced, but the workpiece positioning precision deteriorates
Solution Approach 1:
The patent introduces a guiding mechanism that acts as an intermediary between the workpiece and the holding device. This mechanism includes guide rails or positioning features that physically guide the workpiece into the correct position during attachment, ensuring positioning accuracy without requiring complex alignment procedures.
Solution Approach 2:
The guiding mechanism pre-establishes the correct attachment path and position before the workpiece is fully attached. By providing predetermined guide features, the system ensures that the workpiece automatically assumes the correct position during the attachment process, improving positioning precision without adding operational complexity.
3Device complexity
If the holding portions are fixed, then the device complexity is reduced, but the ease of operation deteriorates
Solution Approach 1:
The patent employs movable holding portions that can dynamically adjust their position during workpiece attachment. The holding portions are designed to move along guide rails or within defined ranges, allowing them to adapt to the workpiece being attached and provide self-aligning assistance, which improves ease of operation while maintaining reasonable structural complexity.
Solution Approach 2:
The movable holding portions provide tactile and visual feedback to the operator during the attachment process. As the workpiece is being attached, the holding portions move in response, giving the operator feedback on the attachment progress and status, making it easier to know when proper attachment has been achieved.

AI summary
A holding device of a cutting machine includes a first arm and a second arm. An adapter that holds a workpiece includes a first projecting portion provided on a first end portion. The first arm includes a first holding portion that is movable in a holding direction and a first elastic member that applies a pressing force to the holding portion toward the second arm. When the adapter is not held by the holding device, the first holding portion is arranged in a position that the first projecting portion passes when the workpiece moves with respect to the holding device in the attaching and detaching direction toward a holding position. The first projecting portion contacts the first holding portion when the workpiece passes a middle position that is a position where the workpiece is in middle of moving in the attaching and detaching direction toward the holding position.
