Adjustable Vacuum Suction Pen for Irregular Object Handling

Solution Overview

Problem

Existing vacuum suction devices struggle to firmly hold products with irregular shapes or uneven materials, particularly when the suction device is not positioned at the center of gravity, and manual devices lack sufficient suction force, while electric devices fail to maintain a reliable grip.

Innovation Solution

A vacuum suction device with adjustable suction modules, including horizontally, vertically, and rotatably movable nozzles, allowing precise alignment with the center of gravity of the product, combined with a sealing mechanism to prevent air leakage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a manual vacuum suction device is used, then the device structure is simple, but the suction force is too weak to firmly hold the product

Engineering Contradiction:

Improvedevice structureVSAvoidsuction force

Core Design Contradiction:

Device complexityVSForce

Solution Approach 1:

The suction nozzle is designed to be movable both horizontally and vertically, allowing dynamic adjustment of the nozzle position to locate and maintain alignment with the product's center of gravity. This dynamic positioning capability enables the system to adapt to products of different sizes and shapes while maintaining effective suction force.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The suction device is divided into separate functional modules: a holder, a movable suction nozzle, and a sealing mechanism. This segmentation allows each component to be optimized independently - the nozzle for positioning, the holder for support, and the sealing mechanism for maintaining vacuum pressure.

Inventive Principle:

Principle #1Segmentation

2Reliability

If an electric vacuum suction device is used, then the suction force is lasting and reliable, but the device cannot firmly hold products with irregular shapes when not positioned at the center of gravity

Engineering Contradiction:

Improvesuction reliabilityVSAvoidadaptability to irregular shapes

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The suction nozzle is designed to be movable both horizontally and vertically, allowing dynamic adjustment of the nozzle position to locate and maintain alignment with the product's center of gravity. This dynamic positioning capability enables the system to adapt to products of different sizes and shapes while maintaining effective suction force.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The device incorporates a sealing mechanism that works in conjunction with the movable nozzle to provide feedback on the quality of the seal. When the nozzle is properly positioned at the center of gravity, the sealing mechanism maintains vacuum pressure; when misaligned, the seal breaks and vacuum is lost, providing immediate feedback for repositioning.

Inventive Principle:

Principle #23Feedback

3Device complexity

If the suction device is positioned away from the center of gravity of an irregular product, then the device structure is simple, but the product cannot be firmly held

Engineering Contradiction:

Improvepositioning mechanismVSAvoidholding reliability

Core Design Contradiction:

Solution Approach 1:

The suction nozzle is designed to be movable both horizontally and vertically, allowing dynamic adjustment of the nozzle position to locate and maintain alignment with the product's center of gravity. This dynamic positioning capability enables the system to adapt to products of different sizes and shapes while maintaining effective suction force.

AI summary

A vacuum suction pen to take reliable hold of objects of different shapes without manual contact includes a holder with an air duct penetrating the holder. A first sleeve is sleeved on one end of the holder, and a first adsorption module is movably arranged on the first sleeve to move along a first direction. The first suction nozzle can move in the horizontal direction, the second nozzle can move in the vertical direction, and the third suction nozzle can rotate around the holder. The positions and relative positions of each suction nozzle on the product to be lifted and manipulated can be adjusted, so as to more accurately locate the center of gravity of products with irregular shapes or of uneven materials, and so as to secure a stable hold on the objects.
