Solution Overview

Problem

Current handling systems for gripping product layers on pallets are either fixed and unsuitable for dividing non-homogeneous pallets or are bulky and impractical for use in cold storage environments, especially on mezzanines or in standard goods lifts.

Innovation Solution

A compact mobile gripping system with a delimiting frame and central opening, featuring independent clamping means arranged peripherally, allowing for efficient gripping and actuation of product layers without protrusion into the central opening, suitable for self-propelled handling devices like forklifts or stackers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If mobile handling systems are used to grip product layers, then operational flexibility and ease of operation are improved, but the device becomes bulky and unsuitable for use in cold storage environments, mezzanines, or standard goods lifts

Engineering Contradiction:
Improveoperational flexibilityVSAvoiddevice bulk
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

The gripping system is divided into modular components: a frame with central opening, separate clamping means for different directions, and distributed actuating means. This segmentation allows each component to be optimized independently and facilitates compact arrangement within limited space.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The actuating means are arranged in the peripheral region of the frame, utilizing the two-dimensional plane of the frame rather than extending vertically. This dimensional reorganization reduces the vertical bulk of the device while maintaining full gripping functionality.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If fixed handling systems are used, then device complexity is reduced, but adaptability to handle non-homogeneous pallets and different product configurations is limited

Engineering Contradiction:
Improvepallet configuration flexibilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system incorporates dynamically adjustable clamping forces through independently controllable actuating means. The clamping forces can be varied to accommodate different product types, layer configurations, and pallet structures, providing adaptability without requiring multiple fixed systems.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The gripping system is designed with universal clamping means that can handle various product configurations and pallet types. The same basic structure and components serve multiple functions: gripping different layer thicknesses, accommodating non-homogeneous products, and working with various pallet dimensions.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Productivity

If actuating means are positioned centrally for efficient gripping, then gripping effectiveness is improved, but the actuating means protrude into the central opening and reduce the available gripping space

Engineering Contradiction:
Improveorder preparation efficiencyVSAvoidcentral opening space
Core Design Contradiction:
ProductivityVSArea of stationary object

Solution Approach 1:

The actuating means are extracted from the central region and relocated to the peripheral region of the frame. This extraction eliminates the conflict between actuating mechanism space and central gripping opening space, allowing both functions to operate optimally without interference.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The frame structure serves as an intermediary element that transmits the clamping force from the peripherally located actuating means to the central gripping region. This mediator allows the actuating means to be positioned away from the center while still effectively gripping products in the central opening area.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The system has a group of clamping units (12) for clamping layered products in a direction. Another group of clamping units (13) clamps the layered products in another direction, which is not parallel to the former direction. A spreader (10) defines a central opening (11) for gripping of the layered products. The clamping units are mounted on a frame bordering the central opening. An actuating unit (17) actuates the clamping units mounted on the frame in a completely circumferential with respect to the central opening.
