Adjustable Gripper Hand for Versatile Article Conveyance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hands used for conveying articles struggle with enhanced conveyance performance, particularly in placing articles on a base and efficiently moving them.
Innovation Solution
A hand design featuring a base, a first holder movable in a predetermined direction, a first driver for moving the holder, and a second holder capable of adjusting its distance from the first holder, allowing for improved alignment and conveyance of articles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the holder is enlarged to hold articles of various sizes, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The holder is divided into a first holder and a second holder that can move independently relative to each other. The second holder can adjust its position in the second direction (width direction) to adapt to different article widths, while the first holder provides stable support. This segmentation allows the holder to accommodate various article sizes without requiring a complete redesign of the entire holder structure.
Solution Approach 2:
The second holder is designed to be movable in the second direction (width direction) relative to the first holder, transforming a static holder into a dynamic one. This dynamic adjustment capability allows the holder to adapt to different article dimensions while maintaining structural simplicity through controlled movement rather than complex reconfiguration.
2Productivity
If a single holder is used, then the device complexity is reduced, but the conveyance performance deteriorates
Solution Approach 1:
The holder is segmented into a first holder for stable support and a second holder for active conveyance and adjustment. This segmentation enables differentiated functionality where the first holder provides a stable base and the second holder performs the conveyance action, thereby improving overall conveyance performance without requiring a completely complex multi-component system.
Solution Approach 2:
The first holder and second holder are merged into an integrated holder assembly that functions as a unified unit while maintaining independent adjustability. The second holder is positioned on the first holder, creating a combined structure that leverages the stability of the first holder while adding the conveyance capability of the second holder, achieving enhanced performance without proportional increase in complexity.
3Adaptability or versatility
If the second holder is made adjustable in the second direction, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The second holder is designed with dynamic adjustability in the second direction (width direction) through a simple driving mechanism. This dynamic capability allows the second holder to move laterally to accommodate different article widths, providing adaptability through controlled movement rather than complex mechanical reconfiguration, thereby maintaining relatively simple device structure.

AI summary
A hand includes: a base; a first holder that is supported to be movable in a predetermined first direction with respect to the base and holds an article; a first driver that moves the first holder in the first direction; and a second holder that is aligned with the first holder in a second direction intersecting with the first direction, is supported to be movable in the first direction with respect to the base, and holds the article. The article held by the first holder and the second holder is placed on the base. The second holder is capable of adjusting a distance from the first holder in the second direction.
