Solution Overview

Problem

Existing warehouse designs face limitations in space utilization, particularly vertical space, due to the constraints of picking station quantity and the need for additional floors or mezzanine constructions, which are not feasible in all regions and consume valuable space.

Innovation Solution

The implementation of virtual order fulfillment levels by arranging picking stations at different heights within the same floor, utilizing raised platforms and vertically stacked connecting conveyor systems to optimize space without additional construction, allowing for efficient use of both vertical and horizontal space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the quantity of picking stations is increased to improve order fulfillment capacity, then productivity increases, but the required floor space and conveyor system complexity increase

Engineering Contradiction:
Improveorder fulfillment capacityVSAvoidfloor space
Core Design Contradiction:
ProductivityVSArea of stationary object

Solution Approach 1:

The patent applies vertical stacking of picking stations to utilize the third dimension (height) instead of expanding horizontally. Multiple picking stations are arranged at different vertical levels, allowing increased order fulfillment capacity without proportionally increasing floor space. The conveyor system connects these vertically stacked stations, enabling efficient material flow between levels.

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

2Productivity

If mezzanine floors are constructed to add more picking levels, then productivity increases, but construction cost and vertical space consumption increase

Engineering Contradiction:
Improvepicking station quantityVSAvoidconstruction requirement
Core Design Contradiction:
ProductivityVSEase of manufacture

Solution Approach 1:

The patent segments the warehouse space into multiple vertical levels using raised platforms rather than constructing complete mezzanine floors. This segmentation approach allows picking stations to be distributed across different heights without requiring full-floor constructions, reducing both construction costs and vertical space consumption while maintaining productivity benefits.

Inventive Principle:
Principle #1Segmentation

3Area of stationary object

If picking stations are arranged at different heights to optimize space utilization, then space utilization improves, but conveyor system complexity increases

Engineering Contradiction:
Improvevertical space utilizationVSAvoidconveyor system arrangement
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The patent merges multiple conveyor functions into a integrated vertical transport system that serves stacked picking stations. The conveyor system combines horizontal and vertical transport capabilities, using elevators or vertical conveyors to move goods between levels and horizontal conveyors within levels, creating a unified system that manages complexity while achieving efficient space utilization.

Inventive Principle:
Principle #5Merging (Combining)
