Wireless Parking Pallet Control via Radio Frequency Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing car parking devices lack a safe and comfortable method for controlling the movement of pallets, as current systems require users to be physically present and often rely on unreliable infrared remote controls or unsafe radio remote controls that can penetrate visual barriers.
Innovation Solution
A method and system using a mobile control device with a code generator, comparator, and controller that outputs an access code for wireless re-entry, ensuring local and basic authentication, allowing authorized users to control pallet movement via radio or other wireless communication, ensuring safety and convenience by maintaining user visibility and eliminating precise alignment requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If infrared remote control is used, then wireless operation is enabled, but the control is unreliable because the infrared beam is deflected by vehicle glass and requires precise aiming
Solution Approach 1:
The patent replaces infrared optical transmission with radio frequency electromagnetic transmission. The control unit transmits control signals via radio waves instead of infrared beams, eliminating the need for line-of-sight communication and precise aiming. This substitution resolves the contradiction by maintaining wireless operation convenience while significantly improving control reliability through radio wave penetration capability.
2Ease of operation
If radio remote control is used, then operation from distance is enabled, but safety is compromised because radio waves can penetrate visual barriers preventing visual monitoring
Solution Approach 1:
The patent implements a feedback mechanism where the control unit must receive visual confirmation from the user that the pallet movement is proceeding correctly. The system provides real-time status information about pallet position and movement state, and the user must actively confirm each step, ensuring visual monitoring is maintained even during remote operation. This feedback loop resolves the contradiction by enabling remote operation while preventing unsafe conditions.
Solution Approach 2:
The patent employs dynamic control where the remote control function is not continuously active but is instead activated in discrete steps requiring user confirmation. The control system dynamically adjusts between automated remote control and user verification modes, ensuring that visual monitoring is maintained at critical moments while allowing remote operation during safe phases of movement.
3Ease of operation
If traditional control panel with buttons is used, then direct control is enabled, but the system becomes complex requiring multiple control panels at individual parking systems
Solution Approach 1:
The patent implements a universal remote control unit that can operate multiple parking systems and pallets through wireless communication. Instead of requiring separate control panels at each parking location, a single multi-functional remote control unit can manage various pallets and parking systems, significantly reducing the overall number of control devices needed while maintaining direct control capability.
Solution Approach 2:
The patent introduces a wireless communication system as an intermediary between the user and the parking control system. The remote control unit acts as a mediator that transmits control signals wirelessly to the parking system control, eliminating the need for physical control panels at each location and simplifying the overall system architecture while preserving direct control functionality.

AI summary
The invention relates to a system and a method for controlling the movement of an automobile parking apparatus that has a drive for the movement of a pallet holding the vehicle to be parked. A control unit is provided for the drive. An output is used to output an access code, and a mobile controller is used to input an input code. The input code is wirelessly transmitted to the control unit, and the control unit enables movement of the palate only if the input code corresponds to the access code.
