Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional workpiece gripping devices are unable to effectively hold workpieces with various shapes or orientations, limiting their versatility in production line automation.
Innovation Solution
A workpiece holding device equipped with multiple holding claws, claw opening/closing members, and a displacing member that allows for adjustable positioning and orientation of the claws to accommodate different workpiece shapes and orientations, optionally using magnet grippers for secure attachment and a contact part to stabilize the workpiece.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional workpiece gripping device is used, then it can grip workpieces with simple shapes, but it cannot grip workpieces with various shapes or orientations
Solution Approach 1:
The gripping device is divided into multiple independent holding claws, each with its own opening/closing mechanism. This segmentation allows each claw to be independently positioned and oriented to accommodate different workpiece shapes, thereby improving adaptability without requiring a completely different device for each shape
Solution Approach 2:
The holding claws are made movable relative to the support member, allowing dynamic adjustment of claw positions and orientations. This dynamic capability enables the same gripping device to adapt to various workpiece shapes and orientations, resolving the contradiction between versatility and structural complexity
2Adaptability or versatility
If multiple holding claws are used to hold workpieces in various orientations, then adaptability improves, but individual control of each claw increases device complexity
Solution Approach 1:
Each holding claw is equipped with its own opening/closing member that can be individually controlled. This segmentation of control mechanisms allows independent adjustment of each claw, enabling precise positioning for various workpiece orientations while maintaining modular simplicity in the control structure
Solution Approach 2:
The opening/closing members serve multiple functions: they control the opening/closing motion of each claw, enable individual positioning, and work collectively with the displacing member to achieve various workpiece orientations. This multi-functionality reduces the need for separate control mechanisms for each function
3Adaptability or versatility
If claw opening/closing members are made movable to accommodate different shapes, then versatility improves, but positioning precision becomes more difficult to maintain
Solution Approach 1:
The opening/closing members are designed to move along predetermined paths or guides on the support member. This controlled movement allows the claws to be repositioned for different workpiece shapes while maintaining precise positioning through the constraints of the movement paths, resolving the contradiction between adjustability and positioning precision
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the stable holding and transportation of workpieces with diverse shapes and orientations, enhancing the device's adaptability and efficiency in production line automation by allowing individual control of each claw for precise gripping and orientation.
Implementation Method 1
a magnet gripper configured to magnetically attract the workpiece may be provided for the holding claw. It is because, by this magnetic attraction, it is possible to prevent detachment of the workpiece from the holding claws.
Implementation Method 2
In this case, for example, after the workpiece is temporarily magnetically attracted (held), and the workpiece can be transferred to the magnet gripper of the holding claws.

AI summary
A workpiece holding device includes a plurality of holding claws configured to hold a workpiece, and holding cylinders as claw opening/closing members configured to displace the holding claws in a direction closer to or away from a first workpiece. The holding cylinders are provided for the holding claws, respectively. Therefore, the plurality of holding claws can be opened/closed individually. The holding cylinders are held on a support disk as a holding member in a movable manner. That is, by moving the holding cylinders to arbitrary positions on the support disk, the holding cylinders are positioned fixedly.
