Sixteen-Wheel Shuttle With Cable-Stayed Jacking for Heavy Loads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current three-dimensional warehouse shuttles with a two-way eight-wheel structure have low carrying capacity, weak obstacle crossing ability, high failure rates, and occupy significant space, failing to meet the demands of busy warehousing and logistics due to their cam jacking structure's wear and tear issues and inefficient force transmission.
Innovation Solution
A jacking linkage type sixteen-wheel four-way shuttle is designed with a support frame, transverse and longitudinal movement drive mechanisms, and a cable-stayed reversing jacking mechanism, featuring symmetrically arranged wheels and a tension adjusting mechanism, which enhances carrying capacity, obstacle crossing ability, and transmission efficiency while reducing space and maintenance needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a two-way eight-wheel structure is used, then the device complexity is reduced, but the carrying capacity and obstacle crossing ability deteriorate
Solution Approach 1:
The shuttle is divided into multiple independent wheel assemblies (eight wheels total) arranged in a specific configuration. Each wheel can independently contact the ground, distributing the load and improving obstacle crossing ability while maintaining manageable structural complexity through modular segmentation of the wheel-support frame system
Solution Approach 2:
The patent transitions from an eight-wheel configuration to a sixteen-wheel configuration by adding another dimension of wheel arrangement. This dimensional expansion in the wheel support system significantly increases carrying capacity and obstacle crossing ability while the modular nature of the addition keeps complexity increases manageable
2Device complexity
If a cam jacking structure is used, then the device complexity is reduced, but the reliability and transmission efficiency deteriorate due to wear and tear
Solution Approach 1:
The patent replaces the traditional cam jacking mechanism with a cable-stayed jacking mechanism. This substitution eliminates the cam-follower contact that causes wear and tear, significantly improving reliability and reducing failure rates. The cable-stayed system uses tensioned cables and triangular truss structures instead of sliding cam surfaces, removing the primary source of mechanical wear
Solution Approach 2:
The cable-stayed jacking mechanism introduces intermediate structural elements (cables, truss members, and triangular support structures) between the jacking force application point and the support frame. These intermediaries distribute forces more evenly and reduce stress concentrations that would otherwise lead to premature failure in cam-based systems
3Ease of manufacture
If a two-way eight-wheel structure is used, then the manufacturing cost is reduced, but the productivity and space utilization deteriorate
Solution Approach 1:
The sixteen-wheel shuttle design serves multiple functions simultaneously: it provides enhanced carrying capacity for heavier loads, improved obstacle crossing ability for varied warehouse terrains, and increased stability for precise positioning. This multi-functionality allows a single shuttle model to replace multiple specialized vehicles, improving overall warehouse productivity and space utilization despite higher individual manufacturing costs

AI summary
A jacking linkage type sixteen-wheel four-way shuttle comprises a support frame, a transverse movement drive mechanism, a longitudinal movement drive mechanism and a cable-stayed reversing jacking mechanism, wherein the transverse movement drive mechanism includes transverse driving wheels, first transverse driven wheels, second transverse driven wheels and third transverse driven wheels; the longitudinal movement drive mechanism includes first longitudinal driving wheels, second longitudinal driving wheels, first longitudinal driven wheels and second longitudinal driven wheels; and, the cable-stayed reversing jacking mechanism includes jacking transverse plates and first/second cable-stayed jacking blocks, in which a ball bearing sleeve is movably arranged in a jacking shaft hole, a cable-stayed jacking pillar is arranged between the front and rear sides of the ball bearing sleeve, and the first/second cable-stayed jacking blocks are connected with each other through a jacking shaft. The shuttle is a sixteen-wheel two-way moving vehicle which is compact, cost-effective and space saving, and which also greatly improves the carrying capacity and obstacle crossing ability.
