Solution Overview

Problem

Existing automated storage systems require an auxiliary grid supporting structure for stability, which occupies space, limits positioning options, and is not cost-efficient, and are vulnerable to earthquake-induced lateral forces.

Innovation Solution

A storage grid structure with base angle brackets, rail angle brackets, and support struts that connect storage column profiles to the floor and rails, providing lateral and vertical stability without interfering with storage bins, and incorporating levelling devices for even surfaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If an auxiliary grid supporting structure is used to ensure stability of the storage grid, then the storage system gains structural stability, but the supporting structure occupies space that could be used for storage, limits positioning options, and increases cost

Engineering Contradiction:
Improvestructural stabilityVSAvoidstorage space
Core Design Contradiction:
Stability of the object's compositionVSArea of stationary object

Solution Approach 1:

The base angle bracket merges the supporting function with the storage column profile by directly connecting to its lower end, eliminating the need for a separate auxiliary grid structure. This integration provides structural stability while maximizing storage space utilization.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The auxiliary grid supporting structure is extracted and replaced by a simplified base angle bracket connection system that attaches directly to the storage column profiles, removing the space-consuming peripheral structure while maintaining stability.

Inventive Principle:
Principle #2Taking out (Extraction)

2Stability of the object's composition

If an auxiliary grid supporting structure is used to ensure stability, then the storage system gains structural support, but the supporting structure requires connection to surrounding walls which limits positioning options

Engineering Contradiction:
Improvestructural supportVSAvoidpositioning options
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The dependency on surrounding walls for structural support is extracted and replaced by self-contained base angle brackets that connect storage column profiles directly to the floor, enabling free positioning anywhere on the floor surface.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The base angle bracket serves as a universal connection element that can be installed on any floor surface without requiring connection to surrounding walls, providing structural support while maintaining positioning flexibility.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Stability of the object's composition

If an auxiliary grid supporting structure is used, then the storage system achieves sufficient stability, but the requirement is not cost efficient

Engineering Contradiction:
Improvesufficient stabilityVSAvoidcost efficiency
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The complex auxiliary grid supporting structure is replaced with simpler, more economical base angle brackets that provide adequate structural support at lower cost, sacrificing unnecessary structural complexity for cost efficiency.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The expensive and complex auxiliary grid structure is extracted and replaced with a cost-effective base angle bracket system that provides sufficient stability without the additional structural elements.

Inventive Principle:
Principle #2Taking out (Extraction)

4Object-affected harmful factors

If the storage grid structure is exposed to high lateral loads due to earthquake, then the building walls supporting the grid may be exposed to additional detrimental loads, but removing the supporting structure compromises stability

Engineering Contradiction:
Improveearthquake resistanceVSAvoidstructural stability
Core Design Contradiction:
Object-affected harmful factorsVSStability of the object's composition

Solution Approach 1:

The base angle bracket connection system is designed to accommodate and dissipate earthquake-induced lateral loads through controlled movement and deformation at the connection points, converting the harmful lateral forces into beneficial stress distribution that protects both the storage system and building walls.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The connection system incorporates dynamic elements that allow controlled movement during earthquake events, enabling the structure to absorb and dissipate lateral energy while maintaining overall stability, rather than relying on rigid fixed connections to walls.

Inventive Principle:
Principle #15Dynamics
