Solution Overview

Problem

Elevator systems do not effectively accommodate passenger trips that involve multiple transportation modes and require precise timing for arrival at a destination, as they only allow for basic reservation of elevator use based on arrival time without considering additional travel portions.

Innovation Solution

The system schedules elevator reservations based on both the elevator portion and additional travel portions of a passenger's trip, determining transit times for each and communicating departure times to passengers, allowing for integration of multiple transportation modes and ensuring timely arrival at the destination.

1Reliability

If the elevator system only reserves based on arrival time without considering additional travel portions, then the reservation system is simple, but the passenger cannot arrive at the destination on time when using multiple transportation modes

Engineering Contradiction:
Improvepunctuality of arrivalVSAvoidreservation system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The passenger trip is segmented into multiple portions (elevator portion and additional portion), with each portion's transit time calculated separately. The system divides the total trip into discrete segments that can be individually timed and optimized, allowing accurate scheduling while maintaining manageable system complexity through modular time calculation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary calculation of transit times for both the elevator portion and additional portion before finalizing the reservation. By pre-calculating the time required for each segment and the total trip, the system can determine the optimal elevator departure time in advance, ensuring punctual arrival without requiring complex real-time adjustments during the journey.

2Measurement precision

If the system calculates transit times for both elevator portion and additional portion, then the arrival time accuracy is improved, but the computational complexity increases

Engineering Contradiction:
Improvearrival time precisionVSAvoidscheduling system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The total trip time is segmented into distinct components (elevator transit time and additional portion transit time), with each segment measured and calculated independently. This segmentation allows for precise measurement of each portion while keeping the computational task manageable by breaking down the overall calculation into smaller, simpler sub-calculations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system uses feedback from the calculated transit times of individual portions to adjust and optimize the elevator departure time. By measuring the time required for each segment and feeding this information back into the scheduling algorithm, the system achieves precise arrival time prediction while maintaining efficient computation through iterative refinement rather than complex one-step calculations.

AI summary

Use of an elevator system can be reserved for a passenger based at least in part on an indicated arrival time for a passenger trip. The passenger trip includes a portion that is carried out using the elevator system and an additional portion. The passenger's elevator reservation is scheduled such that time is allotted for the passenger to complete both trip portions by the indicated arrival time.
