Solution Overview
Problem
Existing parking facilities face challenges in efficiently storing and retrieving motor vehicles in a space-saving manner, particularly in areas with limited space, where the transfer area design is not optimized for compactness and safety.
Innovation Solution
A parking facility with a control device that automatically transports motor vehicles from a parking position to an operating change position and back, allowing for both automatic and dead man's mode operations, eliminating the need for an airlock and enabling space-saving design by requiring user intervention for dead man's mode operations, which enhances security and reduces waiting times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the transfer area is designed as a compact space without airlock, then space usage is optimized and the facility can operate in narrow spaces, but safety risks increase due to direct access between transfer area and parking facility interior
Solution Approach 1:
The transport device dynamically changes its position between transfer area and parking facility interior, acting as a movable barrier that only opens the passage when properly positioned, thus maintaining safety while enabling compact design
Solution Approach 2:
The transport device serves as an intermediary element between the transfer area and parking facility interior, controlling access and ensuring safety protocols are followed while allowing direct access without traditional airlock structures
2Productivity
If the transport device operates in automatic mode between operating change position and parking position, then productivity increases and waiting times are reduced, but the complexity of control systems increases
Solution Approach 1:
The control device automatically manages transport operations between operating change position and parking position without continuous user intervention, enabling high-speed automated vehicle handling while maintaining simplified user interaction through the operating device
Solution Approach 2:
The system dynamically switches between automatic mode (for high-speed transport between operating change position and parking position) and dead man's mode (for safety-critical transfer operations), optimizing both productivity and control simplicity
3Reliability
If the transport device requires user actuation for dead man's mode operations, then safety is enhanced through user presence verification, but operation time increases due to continuous user intervention
Solution Approach 1:
The dead man's mode operates on a periodic actuation basis where the user periodically activates the operating device to maintain transport, ensuring continuous user presence and awareness while enabling efficient batch operations between actuations
Solution Approach 2:
The system dynamically adjusts its operational mode based on the phase of operation: using dead man's mode for safety-critical transfer operations between transfer area and operating change position, and switching to automatic mode for routine transport between operating change position and parking position
