Solution Overview
Problem
Existing parking systems face challenges in achieving high parking space density while maintaining acceptable access times, particularly when multiple parking levels are stacked vertically.
Innovation Solution
The system employs receiving devices that can assume multiple positions, including a transport position and a passing position, allowing for lateral displacement within the parking grid to minimize transverse movement and enable efficient vertical transport, with a control device managing these movements to optimize access times and space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple parking levels are stacked vertically to increase parking space density, then the parking space density is improved, but the access time increases due to longer vertical transport distances
Solution Approach 1:
The receiving devices are made dynamically movable within the parking grid, transitioning between transport positions and passing positions. This dynamic repositioning allows the system to adapt to different operational states, enabling vertical transport while maintaining horizontal accessibility, thus resolving the contradiction between stacking levels for density and maintaining access time
Solution Approach 2:
The system introduces horizontal displacement capability as an additional dimension to the vertical stacking arrangement. By allowing receiving devices to move horizontally to passing positions, the system adds a lateral dimension to the multi-level vertical structure, enabling vehicles to be accessed from intermediate levels without requiring direct vertical alignment, thus maintaining access time while achieving high density
2Ease of manufacture
If receiving devices are left within the parking grid, then the structural design is simplified, but the lifting elements cannot pass the receiving devices for vertical transport
Solution Approach 1:
The receiving devices are designed to be dynamically repositionable between transport positions and passing positions. This dynamic capability allows them to remain within the parking grid structure for ease of manufacture, while temporarily moving to passing positions to enable lifting elements to pass through for vertical transport, thus resolving the contradiction between structural simplicity and transport efficiency
Solution Approach 2:
Before vertical transport occurs, the receiving devices are preliminarily moved to passing positions to clear the path for lifting elements. This preliminary action enables the lifting elements to pass through the parking grid without collision, allowing vertical transport to proceed efficiently while maintaining the receiving devices within the grid structure
3Volume of moving object
If transverse displacements in intermediate levels are minimized, then the parking rack becomes more compact, but the receiving devices cannot be repositioned for vertical transport
Solution Approach 1:
The system implements local quality by providing different positional states for receiving devices in different locations. Receiving devices at intermediate levels have the capability to move to passing positions for vertical transport, while maintaining minimal transverse displacement overall. This localized repositioning capability maintains compactness while enabling necessary adaptability for transport operations
