Wireless Lift Gate Authorization Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lift gate systems rely on wired toggle switches for operation, lacking secure and efficient authorization mechanisms for operators, which can lead to unauthorized use and potential safety hazards.
Innovation Solution
A wireless lift gate system that includes a wireless controller with an authorization controller to verify operator authorization through various methods (e.g., keypad entry, card swiping, wireless signals) before allowing operation, ensuring only authorized personnel can control the lift gate, and includes a main controller that checks conditions before executing commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired toggle switches are used for controlling lift gate operation, then the system is simple and reliable, but the authorization mechanism is lacking and security is compromised
Solution Approach 1:
The authorization controller checks operator authorization before allowing lift gate operation. The system performs preliminary verification of authorization information (keypad code, card swipe, wireless signal) to ensure only authorized personnel can operate the lift gate, preventing unauthorized use before it occurs
Solution Approach 2:
The patent introduces a wireless controller as an intermediary between the operator and the main controller. This wireless controller includes an authorization controller that mediates the operation by verifying authorization information and only transmitting commands to the main controller when authorization is confirmed, adding a security layer without compromising operational reliability
2Object-affected harmful factors
If wireless control with authorization verification is implemented, then security and authorization control are improved, but device complexity increases
Solution Approach 1:
The wireless controller is designed to perform multiple functions: it serves as both the authorization verification device and the command transmission device. The authorization controller within the wireless controller can verify multiple types of authorization information (keypad codes, card swipes, wireless signals) and determine authorization levels, reducing the need for separate dedicated authorization hardware
Solution Approach 2:
The patent combines the authorization control functionality with the wireless control functionality into a single wireless controller unit. The authorization controller is integrated within the wireless controller, which then transmits commands to the main controller. This merging reduces overall system complexity compared to having separate authorization and control systems
3Ease of operation
If multiple authorization methods are provided (keypad, card reader, wireless transmitter), then ease of operation and user convenience are improved, but device complexity increases
Solution Approach 1:
The authorization controller is designed to handle multiple types of authorization information through a single unified interface. It can process keypad codes, card swipe data, and wireless transmitter signals, determining authorization levels for each. This multi-functional design allows operators to choose their preferred method while avoiding the need for separate dedicated systems for each authorization type

AI summary
A lift gate system is provided which in one implementation has a lift gate assembly including an actuator for actuating a lift gate, a main controller configured for controlling the actuator, and a wireless transceiver for receiving an operation command. The system further has a wireless controller including an authorization controller configured for checking that an operator is authorized to operate the lift gate, the wireless controller configured such that upon authorization of the operator by the authorization controller, the wireless controller may wirelessly transmit an operator command to the main controller for controlling operation of the lift gate accordingly.
