Loading Frame Clamping Mechanism for Stable Container Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage and retrieval systems for online retail businesses face inefficiencies in storing tens of thousands of product lines, as single-product stacks require large floor areas and are impractical for perishables or infrequently ordered goods, necessitating a more compact and efficient storage solution.
Innovation Solution
A clamping apparatus is introduced to secure a loading frame within a storage system, utilizing a first and second arm with an engagement apparatus and proximity sensors to detect the frame, allowing for secure loading and unloading of containers by an automatic frame loading system, while restraints limit forward and vertical movement to prevent frame displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If single-product stacks are used to store products, then product storage is simple and accessible, but large floor area is required and storage efficiency is low
Solution Approach 1:
The patent transitions from horizontal single-product stacks to vertical multi-product stacks arranged in a grid framework. Containers are stacked vertically on upright members, utilizing the third dimension (height) to reduce floor area occupancy while maintaining storage capacity and accessibility.
Solution Approach 2:
The framework structure with upright members and horizontal grid structures serves multiple functions: supporting vertical stacks, guiding container movement, and enabling access by load handling devices. This multi-functional design replaces multiple separate storage structures with a single integrated system.
2Productivity
If multi-product stacks are arranged within a framework structure, then storage density is improved and floor area is reduced, but frame stability and container security are compromised
Solution Approach 1:
The framework is divided into multiple upright members arranged in a grid pattern, with each member supporting independent vertical stacks. This segmentation allows the structure to maintain stability through distributed support while accommodating multiple product types in separate containers within the same framework.
Solution Approach 2:
The patent employs horizontal members that curve or bend to engage with containers, providing both support and retention. The curved geometry of horizontal members allows them to secure containers while accommodating slight movements, maintaining both stability and adaptability.
3Ease of operation
If load handling devices operate on tracks at the top of the frame, then container access is enabled, but frame complexity and structural requirements increase
Solution Approach 1:
The load handling devices are integrated with the framework structure by mounting tracks directly on the horizontal members. This merging of functions allows containers to be accessed without requiring separate external handling equipment, reducing overall system complexity while maintaining operational ease.
Solution Approach 2:
Horizontal members serve as intermediaries between the framework upright members and the load handling devices. They provide the mounting surface for tracks while supporting vertical container stacks, mediating between structural support and operational access functions.
4Ease of operation
If multiple load handling devices cooperate to access bins in lowest stack positions, then complete stack accessibility is achieved, but system complexity and coordination requirements increase
Solution Approach 1:
The load handling devices are designed to autonomously navigate the track system and independently access containers at any stack position. Each device can service multiple stacks without requiring complex centralized coordination, reducing control system complexity while maintaining full accessibility.
