Solution Overview

Problem

Existing strapping devices require significant time for cross-strapping operations due to the raising and lowering of the frame of the rotation device.

Innovation Solution

A strapping device with a rotation device integrated into the packing table, allowing for 90-degree rotation of packages without raising and lowering, thereby accelerating cross-strapping operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a lifting and rotation device with a frame is used to rotate packages for cross-strapping, then the package can be rotated through 90 degrees, but a considerable amount of time is required due to raising and lowering operations

Engineering Contradiction:

Improvecross-strapping capabilityVSAvoidtime for cross-strapping operation

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The rotation device is designed to rotate within the horizontal plane (packing table plane) rather than requiring vertical lifting and lowering. This dimensional change eliminates the time-consuming vertical movements while maintaining the 90-degree rotation capability for cross-strapping operations.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The rotation device is made rotatable within the packing table plane, allowing dynamic adjustment of package orientation without fixed vertical positioning. This dynamic horizontal rotation enables faster repositioning compared to static lifting mechanisms.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If a frame-based rotation device is used, then package rotation is enabled, but the device complexity increases due to lifting and lowering mechanisms

Engineering Contradiction:

Improvepackage rotation capabilityVSAvoidcomplexity of rotation device

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The lifting and lowering functions are extracted from the rotation mechanism. The rotation device operates independently within the packing table plane without requiring vertical frame movements, simplifying the overall device structure while maintaining rotation functionality.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The rotation device is integrated directly into the packing table structure, merging the rotation function with the existing packing table framework. This eliminates the need for separate lifting and lowering mechanisms, reducing device complexity.

Inventive Principle:

Principle #5Merging (Combining)

3Ease of operation

If the channel member is interrupted in intersection regions with the frame, then the strapping band can be guided along below the package, but the device complexity increases

Engineering Contradiction:

Improvestrapping band guidanceVSAvoidcomplexity of channel member structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The strapping band guidance is achieved through horizontal routing within the packing table plane rather than requiring vertical interruptions and frame-based pathways. This dimensional approach simplifies the channel member structure while maintaining operational ease.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
