Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional item storage and retrieval systems in warehouses and distribution centers are inefficient, requiring significant human intervention and resulting in low storage density, high operational costs, and potential for lost items.
Innovation Solution
The implementation of stackable storage modules with automated item movement management systems, which utilize modular, elongate frames with movable carrier devices to vertically and horizontally position storage containers, enabling automated retrieval and placement of items with minimal human assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If conventional shelving units with manual storage and retrieval are used, then human operators can easily access and manage items, but storage density is low and operational costs are high
Solution Approach 1:
The storage system is divided into multiple independent stackable modules, each capable of autonomous operation. Each module contains its own conveyor belt system and control mechanisms, allowing the large system to be broken down into manageable, replaceable units that can be individually maintained and operated.
Solution Approach 2:
Multiple storage modules are stacked vertically to form a compact tower structure, with each module nested within the overall framework. This nesting approach maximizes vertical space utilization while maintaining a relatively small footprint, thereby increasing storage density without proportionally increasing the ground area occupied.
2Quantity of substance
If manual storage and retrieval processes are used, then operational flexibility is maintained, but storage density is low and space utilization is poor
Solution Approach 1:
The conveyor belts within each module are designed to move dynamically, automatically transporting items between storage locations and access points. This dynamic movement system eliminates the need for manual item handling while maintaining operational flexibility, as the conveyor speed and direction can be adjusted based on storage and retrieval requirements.
Solution Approach 2:
The automated conveyor system performs storage and retrieval operations autonomously without requiring human operators to physically access and handle items. The system serves itself by automatically positioning items for storage and retrieving them when needed, thereby increasing storage density while maintaining ease of operation through automation.
3Productivity
If automated storage systems are implemented, then operational costs and time are reduced, but system complexity increases
Solution Approach 1:
The automated system is segmented into multiple independent modules, each with its own conveyor belt and control system. This segmentation allows for simplified individual module design and manufacturing, while the overall system achieves high throughput through parallel operation of multiple modules. Each module can be independently maintained, reducing downtime and complexity of system-wide maintenance.
Solution Approach 2:
Each storage module is designed as a universal unit that can perform multiple functions: storing items, retrieving items, and transferring items between levels. The standardized design allows any module to be interchangeably positioned within the stack, providing operational flexibility while simplifying the overall system architecture through repetition of proven, optimized components.
4Quantity of substance
If vertical stacking of storage modules is used, then storage density is increased, but structural stability and safety become concerns
Solution Approach 1:
The storage system is divided into discrete modular units with standardized connection interfaces. Each module is designed as a self-contained structural unit with integrated support features, allowing vertical stacking while maintaining individual structural integrity. The segmentation into standardized modules facilitates precise alignment and stable inter-module connections.
Solution Approach 2:
Multiple storage modules are combined through standardized coupling mechanisms that integrate structural support, alignment, and locking functions. The connection structures merge the individual modules into a unified stable tower, distributing loads across multiple connection points and ensuring overall structural stability while maximizing vertical storage capacity.
