Solution Overview

Problem

Existing storage systems for large board stacks in factories face challenges with high operational height dimensions and material requirements, leading to increased construction and transportation costs due to the need for large and heavy structures.

Innovation Solution

A storage system design with a main wagon featuring at least three rail wheels per crosswise rail, reducing the operational height dimension and using smaller diameter wheels with flexible bogie suspension, allowing the system to fit into standard shipping containers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If rail wheels are placed on both edges of the wagon with long wheelbase, then the load-bearing span is increased, but the height of the structure must be increased or thick and heavy steel plate must be used

Engineering Contradiction:
Improveload-bearing spanVSAvoidwagon structure weight
Core Design Contradiction:
StrengthVSWeight of moving object

Solution Approach 1:

The patent applies local quality by concentrating multiple rail wheels (at least three) at specific points along the crosswise rails rather than distributing them evenly. This creates localized support zones that efficiently bear the load without requiring the entire wagon structure to be strengthened, thus reducing overall material usage and weight while maintaining adequate load-bearing capacity.

Inventive Principle:
Principle #3Local quality

2Length of stationary object

If the operational height dimension is large, then the longitudinal rails must be installed high, but the height and volume of the steel and/or concrete structure of the storage area increases

Engineering Contradiction:
Improveoperational height dimensionVSAvoidstorage area structure volume
Core Design Contradiction:
Length of stationary objectVSVolume of stationary object

Solution Approach 1:

The patent changes the parameter of wheelbase length by using a shorter wheelbase configuration with multiple rail wheels at specific points. This parameter change allows the longitudinal rails to be installed at a lower height position, which directly reduces the operational height dimension and consequently decreases the height and volume of the storage area structure.

Inventive Principle:
Principle #35Parameter changes

3Strength

If the main wagon is a large welded structure, then structural integrity is maintained, but transportation costs increase and manufacturing location options are limited

Engineering Contradiction:
Improvestructural integrityVSAvoidtransportation cost
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The patent applies segmentation by dividing the main wagon into modular components that can be manufactured separately and assembled. The use of standardized rail wheels and modular frame sections allows the wagon to be disassembled for transportation in standard shipping containers, reducing transportation costs and enabling manufacturing at locations with lower costs while maintaining structural integrity through proper connection design.

Inventive Principle:
Principle #1Segmentation
