Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle lift systems lack efficient communication and coordination between multiple lift columns, leading to potential misalignment and uneven lifting of vehicles, especially when dealing with larger or more complex loads.
Innovation Solution
The implementation of a linker communication system that enables synchronized control of multiple lift columns through a centralized control module and remote controllers, using wireless communication and a consensus button to ensure coordinated lifting operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple lift columns are operated independently without centralized coordination, then each column can be controlled individually, but the lifting operation becomes unsynchronized and misalignment occurs
Solution Approach 1:
A centralized controller acts as an intermediary between multiple wireless controllers and lift columns. The centralized controller receives commands from any wireless controller, processes them through a consensus algorithm to ensure synchronization, and distributes coordinated commands to all lift columns. This mediator approach maintains individual control flexibility while ensuring reliable synchronized operation.
Solution Approach 2:
The system implements continuous feedback loops where each lift column reports its position and status to the centralized controller, which then adjusts commands to maintain synchronization. The consensus algorithm uses feedback from all columns to determine the appropriate lifting rate and timing, ensuring that all columns remain coordinated throughout the lifting operation.
2Reliability
If a centralized control system is implemented to coordinate multiple lift columns, then lifting synchronization is improved, but system complexity increases
Solution Approach 1:
The centralized controller performs multiple functions: it acts as a coordinator for synchronization, a communication hub for wireless messages, a consensus algorithm processor, and a command distributor to all columns. By consolidating these diverse functions into a single multi-functional device, the system achieves reliable synchronization without proportionally increasing overall system complexity.
Solution Approach 2:
The system merges the control functions of multiple wireless controllers into a single centralized control logic. Instead of having separate control systems for each column, the centralized controller combines all control decisions into one unified system that manages all columns simultaneously, reducing redundant components and simplifying the overall architecture.
3Ease of operation
If wireless communication is used between controllers and lift columns, then ease of positioning and operation is improved, but communication reliability and coordination between multiple systems becomes difficult
Solution Approach 1:
The centralized controller serves as a communication intermediary that receives all wireless messages from any controller, standardizes the message format, and ensures reliable transmission to the appropriate lift columns. This mediator approach prevents message loss and coordination errors by centralizing the communication protocol management.
Solution Approach 2:
The system implements acknowledgment and confirmation protocols where lift columns send feedback messages to the centralized controller to confirm receipt and execution of commands. This feedback mechanism ensures that no communication is lost and that all columns are properly coordinated, even in wireless environments with potential interference.

AI summary
A vehicle lift system includes a plurality of lift groups, each lift group including a plurality of lift columns configured to lift a vehicle and a control device. The system further includes a linker module comprising a processor and a memory, wherein the memory is encoded with programming instructions executable by the processor to receive at least one user command from the control device of at least one of the plurality of lift groups, poll the control device of each lift group in the plurality of lift groups, determine, based on the polling, whether the received command can be executed, responsive to determining that the received command can be executed, send a custom instruction to each lift group to execute the received command, and responsive to determining that the received command cannot be executed, provide a notification to the user.
