Elevator Onboard Position Assignment for Alighting Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing elevator system is inefficient in reducing the time required for passengers to alight due to improper assignment of passengers to onboard positions, leading to suboptimal operation efficiency.
Innovation Solution
An elevator system with a communication unit that assigns onboard positions based on destination floor information, using a car assignment unit and onboard position assignment unit to optimize passenger placement, ensuring efficient boarding and alighting processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple passengers are assigned to one section in the car, then the car can accommodate more passengers, but the time required to alight from the car increases because passengers are not lined up in accordance with the order in which they alight
Solution Approach 1:
The car interior is divided into multiple sections, and each section is further divided into multiple onboard positions. This segmentation allows passengers to be assigned to specific positions within sections, enabling them to alight in the correct order while maintaining high passenger capacity. The segmentation of the car into sections with multiple positions resolves the contradiction by allowing both many passengers per section and efficient alighting order.
Solution Approach 2:
Passengers are assigned to specific onboard positions in advance based on their destination floors before boarding. This preliminary assignment ensures that when passengers need to alight, they are already positioned in the correct order, eliminating waiting time and ensuring efficient alighting while maintaining high capacity utilization.
2Ease of operation
If passengers are not assigned to specific onboard positions, then the system is simpler to operate, but the operation efficiency of the elevator cannot be improved
Solution Approach 1:
The system automatically assigns passengers to onboard positions based on their destination floor information without requiring manual intervention. The control unit autonomously processes destination floor data and makes position assignments, maintaining operational simplicity while significantly improving elevator operation efficiency through automated position optimization.
Solution Approach 2:
The system uses destination floor information as feedback to automatically adjust passenger position assignments. By continuously monitoring and using destination floor data, the system optimizes passenger placement to improve operation efficiency while keeping the user interface simple and easy to operate.
3Device complexity
If the elevator system does not transmit assigned position information to movable bodies, then the system complexity is reduced, but the alighting process becomes less efficient
Solution Approach 1:
The control unit acts as an intermediary that receives destination floor information from movable bodies, processes position assignments, and transmits this information back to the movable bodies. This intermediary role enables efficient alighting through information exchange while keeping the overall system architecture manageable and not excessively complex.
