Solution Overview

Problem

Compact warehouse systems face a challenge in providing sufficient height for service vehicles to operate, as the available space above the grid is limited, making it difficult for service vehicles to accommodate operators for maintenance tasks.

Innovation Solution

A compact service vehicle designed to operate at the top level of storage modules in compact warehouse systems, featuring rollers that engage with rails, a platform for the operator to lie on, and a control system for movement and operation, allowing the vehicle to move along the top level rails and perform maintenance tasks within the limited height constraints.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the service vehicle is designed to accommodate a sitting or standing operator, then the operator can perform maintenance tasks comfortably, but the vehicle height exceeds the limited space above the grid in compact warehouse systems

Engineering Contradiction:
Improveoperator comfort for maintenance tasksVSAvoidservice vehicle height
Core Design Contradiction:
Ease of operationVSLength of stationary object

Solution Approach 1:

Instead of having the operator sit or stand on the service vehicle platform, the invention inverts the conventional arrangement by having the operator lie down on the platform. This inversion allows the operator's body to be positioned horizontally, significantly reducing the vertical height requirement of the service vehicle while still accommodating the operator for maintenance tasks in the limited space above the grid

Inventive Principle:
Principle #13The other way round (Inversion)

2Ease of operation

If the height above the grid is increased to accommodate service vehicles, then operators can perform maintenance tasks, but the storage capacity of the compact warehouse system is reduced

Engineering Contradiction:
Improvemaintenance task accessibilityVSAvoidstorage capacity
Core Design Contradiction:
Ease of operationVSVolume of stationary object

Solution Approach 1:

The invention resolves this contradiction by inverting the operator positioning from sitting/standing to lying down, which reduces the service vehicle height and allows it to operate within the existing limited space above the grid without requiring additional height that would compromise storage capacity

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The invention changes the dimensional orientation of the operator from vertical (sitting/standing) to horizontal (lying down), effectively utilizing the horizontal dimension more efficiently while minimizing the vertical dimension requirement, thereby preserving storage capacity while enabling maintenance operations

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

AI summary

The present disclosure relates to a service vehicle (300) for use in a warehouse system comprising at least one storage module (100) having a storage area (102) adapted to accommodate a plurality of stacks of storage bins, and a top level (104) arranged above the storage area (102). The service vehicle (300) is configured for movement at the top level (104) of the storage module (100) and comprises rollers (310) engageable in rails (110) extending at the top level (104), and a platform (320) for carrying an operator, the platform designed for carrying the operator in a lying position. When the rollers (310) engage in the top level rails (110) of the storage module (100), the service vehicle (300) is movable along said rails (110) at the top level (104) of the storage module (100) with an operator carried by the platform (320).
