Automated Parking System Vertical Stacking AGV Lifts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automated parking systems that use automated guided vehicles (AGVs) and vertical reciprocating conveyors (VRCs) do not efficiently achieve high parking density, as they are not compatible with devices that enable multiple vehicles to be arrayed vertically in a single space, and manual control of prior art parking lift devices offsets labor efficiencies.
Innovation Solution
An automated parking system that integrates AGVs with suspended tray supports and hoist mechanisms, allowing AGVs to transport trays with vehicles between levels, using electro-optical signage, photo-optical sensors, and Hall effect sensors for precise navigation and efficient space utilization, enabling multiple vehicles to be stored vertically in a single space.

Engineering Contradiction Analysis
1Quantity of substance
If multiple vehicles are arrayed vertically in a single parking space using lift devices, then parking density is improved, but device complexity increases due to the need for suspended tray supports and hoist mechanisms
Solution Approach 1:
The patent implements nested doll by placing multiple vehicles vertically one above another in the same parking space. The tray support structure is suspended from the ceiling and can be lowered to receive a vehicle, then lifted to allow another vehicle to be parked in the space below. This nesting arrangement enables multiple vehicles to occupy a single parking space footprint, directly increasing parking density while managing the complexity through a standardized lift mechanism.
Solution Approach 2:
The patent applies dimensionality change by transitioning from horizontal parking arrangements to vertical stacking. Instead of expanding parking capacity horizontally, the system utilizes the vertical dimension by employing suspended tray supports that can be lowered to ground level for vehicle entry, then raised to enable vertical stacking. This dimensional shift allows multiple vehicles to be accommodated in the same horizontal footprint, resolving the parking density issue.
2Productivity
If automated guided vehicles are used to transport trays, then labor costs are reduced, but device complexity increases due to the need for sensors and automated control systems
Solution Approach 1:
The patent implements self-service by deploying automated guided vehicles (AGVs) that autonomously navigate the parking facility to transport trays between parking spaces and the vertical stacking mechanism. The AGVs are equipped with sensors and automated control systems that enable them to locate parking spaces, position trays, and coordinate with the lift mechanisms without human intervention. This automation eliminates manual labor while the system manages its own complexity through integrated control.
Solution Approach 2:
The patent applies mechanics substitution by replacing manual mechanical operations with automated systems. Instead of workers manually moving trays and coordinating vehicle parking, the system uses AGVs with sensors and automated control to perform these tasks. The mechanical system is enhanced with electronic and optical components (sensors, control systems) that enable autonomous operation, thereby reducing labor requirements while managing system complexity through automation.
3Ease of manufacture
If above grade parking garages are used, then construction cost is reduced, but aesthetic appearance deteriorates due to visible structural elements
Solution Approach 1:
The patent applies nesting by suspending tray supports from the ceiling of the parking facility, allowing vehicles to be stacked vertically in a compact arrangement. This nested configuration enables the parking structure to be integrated within or adjacent to buildings without requiring extensive above-grade construction, thereby maintaining aesthetic appearance while controlling construction costs through efficient space utilization.
Solution Approach 2:
The patent utilizes dimensionality change by transitioning from traditional horizontal above-grade parking garages to vertical stacking arrangements. The suspended tray support system enables vehicles to be parked in multiple levels within the same horizontal footprint, reducing the need for expansive above-grade structures and preserving architectural aesthetics while maintaining cost-effectiveness.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system significantly increases parking density by automating the movement and storage of vehicles, reducing labor costs, and enhancing operational efficiency while maintaining aesthetic appeal by eliminating the need for below-grade structures.
Implementation Method 1
Each lift device comprises a tray support and a hoist mechanism that preferably includes a motor, pulleys and chains or cables extending from the tray support around the pulleys and to the hoist mechanism
Implementation Method 2
The system may also include a plurality of trays, each of which has a parking platform and a plurality of legs depending down from the parking platform

AI summary
A parking system includes parking trays, each of which includes a parking platform for supporting a vehicle thereon and legs depending down from the parking platform. Automated guided vehicles (AGVs) can move between the legs of a tray and then lift the tray with the vehicle thereon for moving the vehicle to or from parking spaces in a parking facility. Each parking space has a vehicle lift device suspended from the ceiling. Each vehicle lift device includes a tray support for supporting the tray and the vehicle thereon. The AGV can move the tray and the vehicle into a position at the parking space so that the tray and the vehicle can be lifted by the vehicle lift device. Thus, another vehicle can be moved into position below the lifted tray and vehicle.
