Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional lifting systems use multiple sensors and cables for control, then the lifting system can operate with precise control, but the system complexity increases and safety risks arise
Solution Approach 1:
The patent replaces mechanical cable connections and traditional sensor systems with a wireless communication system using RFID technology. The lifting device communicates its status and position wirelessly to the control unit, eliminating the need for physical cables and reducing system complexity while maintaining reliable control and safety monitoring.
Solution Approach 2:
The control unit serves multiple functions: it receives wireless signals from the lifting device, processes position data, controls the lifting operation, and monitors safety zones. This multi-functional approach reduces the need for separate dedicated components for each function, thereby reducing overall system complexity.
2Ease of operation
If physical cables and sensors are integrated into the lifting system, then control precision is achieved, but operational flexibility is reduced and safety hazards increase
Solution Approach 1:
The patent eliminates physical cables by implementing a wireless communication system where the lifting device transmits its status and position information wirelessly to the control unit. This removes the safety hazards associated with cables while maintaining precise control capabilities.
Solution Approach 2:
The lifting device automatically communicates its own status, position, and operational state to the control unit through wireless signals. This self-service approach eliminates the need for external sensors and cable connections, improving operational flexibility while reducing safety risks.
3Measurement precision
If separate height sensors are used to monitor carrier position, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The lifting device's wireless communication system serves multiple purposes: it transmits operational status, position information, and height data to the control unit. This multi-functional communication system eliminates the need for separate dedicated height sensors, reducing system complexity while maintaining precise measurement capabilities.
Solution Approach 2:
The patent merges the height measurement function with the existing wireless communication system of the lifting device. The same wireless signal that communicates operational status also carries position and height information, consolidating multiple functions into a single system rather than using separate sensors.

AI summary
The present invention relates to a lifting system and method for lifting a vehicle. The lifting system has one or more lifting devices and includes a frame with a carrier configured for carrying the vehicle; a drive for driving the carrier in at least one of the ascent or descent of the carrier; and a controller with an indoor positioning system. The controller determines the location and the height of the carrier in at least one of the ascent or descent of the carrier of the one or more lifting devices. The controller has a remote control, and the controller further has a monitoring system configured for monitoring a safety zone. The monitoring system monitors a three-dimensional zone and the safety zone has an inner zone, an intermediate zone and an outer zone.
