Solution Overview

Problem

Compact clamping devices struggle to handle non-flat panels due to inadequate contact area, which prevents sufficient gripping and lifting of irregularly shaped objects like metal, granite, ceramic, glass, or concrete plates.

Innovation Solution

The introduction of add-on plate assemblies that attach to the sides of the objects or jaws of the clamping device, increasing the contact area by providing flat surfaces or accommodating protruded portions, allowing for better grip and lift of non-flat panels through adjustable and compressible materials.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a compact clamping device with parallel jaws is used, then the device structure is simple and compact, but it cannot properly handle non-flat panels due to inadequate contact area

Engineering Contradiction:
Improveclamping device structureVSAvoidability to handle non-flat panels
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The clamping device is divided into a base clamping device and separate add-on plate assemblies. The add-on plates can be attached to the jaws or to the panels to be clamped, allowing the system to adapt to different panel shapes while maintaining the simplicity of the base device structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Add-on plate assemblies serve as intermediary components between the clamping jaws and non-flat panels. These plates provide the necessary flat contact surfaces for the jaws to grip, while accommodating protruded portions of irregular panels through adjustable and compressible materials.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If add-on plate assemblies are attached to increase contact area, then the gripping capability on non-flat panels is improved, but the device complexity increases

Engineering Contradiction:
Improvegripping capabilityVSAvoidclamping device structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The clamping system is segmented into modular components: the base clamping device and detachable add-on plate assemblies. This segmentation allows the plates to be added only when needed for non-flat panels, maintaining simplicity for standard flat panels while providing enhanced gripping capability when required.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The add-on plate assemblies incorporate adjustable and compressible materials that can dynamically adapt to the shape of non-flat panels. This dynamic capability allows the plates to conform to irregular surfaces, maximizing contact area and gripping reliability without requiring a completely complex fixed-structure device.

Inventive Principle:
Principle #15Dynamics

AI summary

Attachments for a clamping device can be used to increase the contact area between the jaws and the object to allow the clamping device to handle irregular objects, such as non-flat panels of metal, granite, ceramic, glass, quartz, or concrete plates. The attachments can include plate assemblies to be attached to the sides of the irregular objects. The attachments can include jaw plate assemblies to be attached to the sides of the jaws of the clamping device.
