Networked Lift Column Control Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lift systems lack a comprehensive solution for synchronizing the operation of multiple columns to ensure stability and precise control of vehicle lifting and lowering, particularly in scenarios requiring different ascent or descent rates or correcting height differences.
Innovation Solution
The system employs a network of interconnected lift columns with integral cables and processors that communicate via wired or wireless protocols, allowing for synchronized operation, individual control, and automatic master/slave configuration to manage column groups, ensuring uniform height and rate adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple local controllers are interlinked by a serial data link network to enable remote control of multiple columns, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple local controllers into a unified control system where controllers are interconnected through a serial data link network. This merging allows a single remote controller to manage multiple lift columns simultaneously, improving operational ease while distributing control functions across the networked controllers to manage complexity.
Solution Approach 2:
The control system is designed with universal functionality where any local controller can serve as a master controller for the entire lift system. The serial data link network enables any controller to communicate with all other columns, making the system multi-functional and adaptable to different operational scenarios without requiring specialized controllers for each column.
2Adaptability or versatility
If a serial data link network is used to interconnect local controllers for remote operation, then the adaptability is improved, but the reliability decreases
Solution Approach 1:
The control system is segmented into independent local controllers, each capable of autonomous operation for its associated column. This segmentation ensures that if one controller or communication link fails, other columns can continue to operate independently or be controlled through alternative controllers in the network, maintaining system reliability while preserving adaptability.
Solution Approach 2:
The serial data link network implements feedback mechanisms where controllers continuously monitor the status and position of each lift column. This real-time feedback allows the system to detect and respond to failures or anomalies, maintaining reliable operation by adjusting control signals or alerting operators to issues while preserving the adaptable networked control architecture.

AI summary
A lift control interface is operable to control and monitor a lift system. Each lift column in the system has such a lift control interface. The lift control interface allows a user to assign lift columns to a lift system. One or more of the assigned lift columns may be assigned to a column control group. The user may lock the selection of these columns. The status of the assigned, selected, and locked lift columns may appear on every lift control interface in the lift system. The user may govern operation of the selected columns in the column control group from a single control interface, such as any control interface at any of the selected columns. The lift control interfaces may include visual representations showing the relationships between the lift columns and a vehicle, such as with lift column icons being positioned around a vehicle icon.
