Solution Overview

Problem

Existing gripping devices for large format sheet-shaped elements, such as tiles or glass sheets, face challenges in adapting to varying pile dimensions, facilitating easy maneuverability, and providing a stable grip, especially when the elements have irregular shapes or undercuts, while also being compact and lightweight for efficient storage and transport.

Innovation Solution

A gripping device comprising a pair of adjustable longitudinal bars with suction gripping members, a transverse crossbar, and interconnection bodies that allow for adjustable length and orientation, enabling flexible positioning and handling of sheet-shaped elements with regular or irregular shapes, and reducing the device's weight and dimensions for easier storage and use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the gripping device uses rigid bars with suction cups to grip sheet-shaped elements, then the grip stability is improved, but the device cannot adapt to varying pile dimensions and irregular shapes

Engineering Contradiction:
Improvegrip stabilityVSAvoidadaptability to varying pile dimensions and irregular shapes
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent applies the dynamics principle by making the longitudinal bars telescopic with adjustable lengths. The bars can extend or retract to adapt to different pile heights and element sizes while maintaining grip stability through suction cups. This dynamic adjustment capability allows the device to handle both regular and irregular shapes effectively.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The gripping device is divided into modular components including multiple longitudinal bars, crossbars, and suction cup assemblies. Each longitudinal bar can be independently adjusted, and the bars are connected through interconnection bodies allowing flexible configuration. This segmentation enables adaptation to various pile dimensions and irregular shapes while maintaining stable gripping through distributed suction points.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the gripping device uses adjustable length bars to adapt to different formats, then the versatility is improved, but the device complexity increases

Engineering Contradiction:
Improveadaptability to different sheet formatsVSAvoidstructural complexity of adjustable mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The telescopic longitudinal bars are designed with nested segments that slide within each other. The interconnection bodies use nested structural elements where crossbars can be inserted into and locked onto the longitudinal bars at various positions. This nesting approach provides adjustability without requiring complex external mechanisms, keeping the device relatively simple while achieving versatility.

Inventive Principle:

3Volume of moving object

If the gripping device is made compact for storage, then the storage efficiency is improved, but the ease of operation for maneuverability is reduced

Engineering Contradiction:
Improvestorage volumeVSAvoidmaneuverability during handling operations
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The device features collapsible and telescopic components that allow it to be compacted for storage and expanded for operation. The longitudinal bars can be retracted into each other, and the crossbars can be folded or removed. During handling operations, the bars extend to provide adequate leverage and control, ensuring ease of maneuverability while maintaining compact storage capability.

Inventive Principle:
Principle #15Dynamics
