Solution Overview

Problem

Existing automated storage and retrieval systems face inefficiencies in managing storage containers of varying fill levels, leading to suboptimal use of storage space and potential collisions or handling issues.

Innovation Solution

The system incorporates a tool to adjust the height of height-adjustable storage containers based on filling levels, using a connection structure that allows the relative positioning of upper and lower frames to change the container's height, and a control system to determine optimal storage locations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of stationary object

If storage containers are stacked one on top of another to form stacks in storage columns, then storage space utilization is improved, but containers with varying fill levels cannot be optimally stored and may cause handling issues or collisions

Engineering Contradiction:
Improvestorage space utilizationVSAvoidhandling reliability
Core Design Contradiction:
Volume of stationary objectVSReliability

Solution Approach 1:

The storage container is designed with adjustable height capability, allowing the container's vertical dimension to dynamically adapt to the fill level of stored items. This enables optimal space utilization in stacked configurations while maintaining safe handling clearances, resolving the contradiction between maximizing storage volume and ensuring reliable handling operations.

Inventive Principle:
Principle #15Dynamics

2Productivity

If fixed-height storage containers are used, then system simplicity is maintained, but storage efficiency is reduced when dealing with varying fill levels

Engineering Contradiction:
Improvestorage efficiencyVSAvoidcontainer structure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The storage container is segmented into adjustable height sections, allowing independent adjustment of the container's vertical dimension. This segmentation enables the container to adapt to varying fill levels without requiring a completely complex reconfigurable structure, thus improving storage efficiency while controlling structural complexity.

Inventive Principle:
Principle #1Segmentation

3Volume of stationary object

If storage containers are adjusted to different heights, then space utilization is optimized, but the risk of collisions or handling issues during movement increases

Engineering Contradiction:
Improvestorage space utilizationVSAvoidcollision risk
Core Design Contradiction:
Volume of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The system incorporates height detection and control mechanisms that provide feedback during container movement and stacking operations. This feedback system monitors container heights and adjusts positioning to prevent collisions, enabling optimized space utilization through variable heights while maintaining safety during handling operations.

Inventive Principle:
Principle #23Feedback
