Segmented Suction Hand for Inclined Articles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand devices struggle to stably hold a wide variety of articles due to limitations in accommodating articles of different heights and inclined surfaces, as they often require larger sizes and increased weight to maintain stability.
Innovation Solution
The hand device incorporates multiple independently movable suction units on both the upper and side surfaces, with adjustable positions and collective suction control, allowing for flexible adaptation to various article shapes and sizes by inclining and positioning the suction units to ensure secure grip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single suction unit is used, then the device structure is simple, but it cannot stably hold articles with different heights and inclined surfaces
Solution Approach 1:
The hand is divided into multiple independent suction units (first suction unit and second suction unit) that can be positioned at different locations and orientations. Each suction unit can independently contact different portions of the article, enabling stable holding of articles with varying heights and inclined surfaces while maintaining manageable structural complexity through modular design
Solution Approach 2:
The second suction unit is configured to contact the article from a different spatial dimension (side surface) compared to the first suction unit (upper surface). This multi-dimensional contact approach enables the hand to stably hold articles with inclined surfaces and different heights by distributing contact points across multiple spatial dimensions
2Adaptability or versatility
If multiple suction units are added to increase adaptability, then the ability to hold various articles improves, but the device size and weight increase
Solution Approach 1:
The second suction unit is configured to be movable relative to the first suction unit, allowing dynamic adjustment of the contact position and orientation. This mobility enables a single movable unit to perform the function of multiple fixed units, expanding the range of holdable articles without proportionally increasing device weight
Solution Approach 2:
The second suction unit is designed to serve multiple functions: it can contact side surfaces of articles, adjust to different article heights, and compensate for inclined surfaces. This multi-functionality allows a single suction unit to replace what would otherwise require multiple specialized suction units, reducing overall device weight while maintaining versatility
3Stability of the object's composition
If larger size hand device is used, then the stability to hold articles improves, but the device weight and size increase
Solution Approach 1:
The hand device is segmented into multiple compact suction units distributed at different positions rather than using a single large suction unit. This segmentation allows stable holding of articles through multiple contact points while keeping the overall device volume compact by placing suction units only where needed

Function Achieved in This Case
This solution enables the hand device to stably hold a wider range of articles, including those with different heights and inclined surfaces, while preventing the need for increased size and weight, thus improving versatility and reducing the risk of article damage during handling.
Implementation Method 1
The hand holds the article by suction, pinching, or jamming

AI summary
According to one embodiment, a hand includes a first holding unit, and a second holding unit. The first holding unit includes a plurality of first holding portions capable of holding an article. A plurality of the first holding units is provided in a second direction and is movable independently of each other in a first direction crossing the second direction. The second holding unit is movable in a third direction crossing a plane parallel to the first direction and the second direction. The second holding unit includes a plurality of second holding portions capable of holding the article.
