Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem

Innovation Solution
A cable car station with a monitoring section divided into zones, equipped with zone detection devices and cable car cabin positioning devices, allowing for independent determination of the cabin's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If cable car cabin position is determined using cable speed or tire conveyor speed, then the positioning system is simple, but the positioning accuracy and reliability deteriorate because it depends on the speed of moving components
Solution Approach 1:
The patent replaces the mechanical speed-based positioning system with an electromagnetic sensing system. Active sensors (RFID readers) and passive positioning devices (RFID tags or magnets) create an electromagnetic field-based positioning method that is independent of cable or conveyor speed, thereby improving measurement precision without excessive complexity increase
Solution Approach 2:
The patent introduces RFID tags or magnets as intermediary positioning devices attached to the cabin, and RFID readers as intermediary sensing devices mounted on the station. These intermediaries enable precise position detection without directly measuring cable speed or conveyor speed, resolving the contradiction between accuracy and complexity
2Ease of operation
If active sensors are placed in the cable car station, then data processing and maintenance become easier, but the system complexity increases
Solution Approach 1:
The passive positioning devices (RFID tags or magnets) attached to the cabin are self-contained and require no power supply or data processing, while the active sensors in the station automatically detect and process data. This self-service arrangement simplifies operation and maintenance while managing system complexity
Solution Approach 2:
The active sensors serve multiple functions: detecting cabin position, determining zone boundaries, and providing data to the control system. This multi-functionality reduces the need for separate systems, thereby easing operation and maintenance without proportionally increasing complexity
3Reliability
If the monitoring section is divided into multiple zones with detection devices at each boundary, then position determination reliability improves, but the system complexity increases
Solution Approach 1:
The monitoring section is segmented into multiple zones with detection devices at boundaries. This segmentation allows independent verification of position in each zone, improving reliability through distributed detection while managing complexity through modular zone management
Solution Approach 2:
Each zone detection device provides feedback about cabin position to the control system. This feedback mechanism enables continuous position verification and cross-checking across zones, enhancing reliability while the systematic feedback loop manages complexity through standardized processing
