Innovation Solution

A shuttle vehicle level-switching hoist with a stereoscopic support frame and vehicle carrying device that includes a lifting driving member for vertical movement and a rotatable vehicle carrying structure, enabling both lifting and rotating functions for two-way shuttle vehicles, simplifying shelf and laneway arrangements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a four-way shuttle vehicle hoist is used, then the shuttle vehicle can move in both left-right and front-back directions, but the cost increases and the arrangement of shelves and lanes becomes complex

Engineering Contradiction:

Improveshuttle vehicle movement capabilityVSAvoidshelf and lane arrangement complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The hoist system is segmented into independent functional modules: a lifting mechanism for vertical movement and a rotating mechanism for horizontal orientation changes. This segmentation allows the hoist to serve multiple lanes sequentially rather than requiring simultaneous access from all directions, simplifying the overall system arrangement.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The hoist incorporates dynamic capabilities through its rotating mechanism that can change orientation to serve different lanes. Instead of a static structure requiring fixed multi-directional access, the rotating hoist dynamically repositions itself to serve two-way shuttle vehicles, reducing the need for complex intersecting lane arrangements.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If a four-way shuttle vehicle hoist is used, then the shuttle vehicle can move in both left-right and front-back directions, but the cost increases

Engineering Contradiction:

Improveshuttle vehicle movement capabilityVSAvoidsystem cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The hoist is designed as a universal device that can serve multiple lanes through rotation and lifting operations. Instead of requiring separate hoists for different directions or complex four-way configurations, this multi-functional hoist handles various operational scenarios (vertical transport, horizontal repositioning, serving different lanes) with a single integrated structure, reducing overall system cost.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention extracts and separates the rotating function from complex four-way hoist designs, creating a dedicated rotation mechanism that works in conjunction with a lifting mechanism. This extraction allows for simpler, more cost-effective design compared to integrated four-way hoists, while still achieving the necessary versatility for two-way shuttle vehicle operations.

Inventive Principle:

Principle #2Taking out (Extraction)

3Adaptability or versatility

If existing hoist systems are used, then lifting function is provided, but rotating function is missing and they are not suitable for two-way shuttle vehicles

Engineering Contradiction:

Improvehoist functionalityVSAvoidhoist structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The invention merges the lifting mechanism and rotating mechanism into a single integrated hoist structure. The lifting mechanism provides vertical movement while the rotating mechanism enables horizontal orientation changes, and both functions work together in a unified system. This combination achieves enhanced adaptability for two-way shuttle vehicles without proportionally increasing complexity, as the mechanisms share common structural elements and control systems.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A shuttle vehicle level-switching hoist for a stereoscopic warehouse and a shuttle vehicle conveying device are provided. The shuttle vehicle level-switching hoist includes: a stereoscopic support frame and a vehicle carrying device for carrying the shuttle vehicle, the stereoscopic support frame is provided with a lifting driving member configured to drive the vehicle carrying device to move in a vertical direction; the vehicle carrying device is located in the stereoscopic support frame, and the vehicle carrying device includes: a main frame structure and a rotatable vehicle carrying structure arranged in the main frame structure. The hoist has both lifting and rotating functions, and may be suitable for the two-way shuttle vehicle. The arrangement of the matched stereoscopic shelf and laneway is relatively simple, and the article transportation of the two-way shuttle vehicle between different levels of the same stereoscopic shelf and between different stereoscopic shelves may be realized.
