Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If two parallel conveyor sections are used to increase palletizer output, then productivity increases, but device complexity and costs increase

Engineering Contradiction:

Improvepalletizer outputVSAvoidstructural input

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The conveyor device is divided into multiple independent rotating devices (at least three) that can process packages separately and simultaneously. Each rotating device handles a portion of the layer pattern construction, enabling parallel processing without requiring duplicate conveyor sections. This segmentation allows high productivity while maintaining a single integrated conveyor structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces rotational movement as an additional dimension of operation. Instead of using parallel conveyor sections to achieve parallel processing, the invention uses rotating devices that can orient and position packages in different rotational positions simultaneously. This dimensional change from linear parallel conveyors to rotational positioning enables high output without duplicating the entire conveyor structure.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Productivity

If two parallel conveyor sections are used to build layer pattern rows simultaneously, then productivity increases, but acquisition, maintenance, and operation costs increase

Engineering Contradiction:

Improvelayer pattern construction speedVSAvoidcosts

Core Design Contradiction:

ProductivityVSEase of manufacture

Solution Approach 1:

Each rotating device is designed to perform multiple functions: conveying packages, rotating them to required orientations, and positioning them in the correct positions for layer pattern construction. This multi-functionality eliminates the need for separate specialized conveyor sections for different rows, reducing overall system complexity and costs while maintaining high construction speed.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines the functions of multiple conveyor sections into a single integrated conveyor device with multiple rotating stations. Instead of having separate conveyors for different rows, the invention merges these functions into one device that can handle multiple rows simultaneously through its rotating mechanisms, thereby reducing acquisition, maintenance, and operation costs.

Inventive Principle:

Principle #5Merging (Combining)

3Stability of the object's composition

If packages are rotated on conveyor belt to form layer patterns, then layer pattern stability improves, but device complexity increases

Engineering Contradiction:

Improvelayer pattern stabilityVSAvoidrotating device configuration

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The rotating devices are positioned at specific locations along the conveyor where rotation is needed for layer pattern formation. Each rotating device provides localized rotational capability at the point of use, rather than requiring the entire conveyor system to be complex. This localized approach maintains layer pattern stability while minimizing overall device complexity.

Inventive Principle:

Principle #3Local quality
