Elevator Dispatch Presence Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional destination dispatch elevator systems often assign cars based on predetermined parameters, leading to inefficiencies and increased wait times due to users making fake requests to prioritize their travel time over others, which results in decreased occupancy and increased travel times for all passengers.
Innovation Solution
The system employs a presence detector, such as a touch sensor, proximity sensor, or camera, to verify user presence and authenticity of requests, allowing for more accurate car assignment and reducing redundant or fake requests by prompting users to cancel or ignore subsequent identical requests, thereby improving scheduling and reducing wait times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If destination dispatch systems use predetermined parameters for car assignment, then system efficiency is improved, but user preferences such as desired car occupancy and wait time are not aligned
Solution Approach 1:
The system dynamically adjusts car assignment parameters based on real-time user input and preferences rather than relying solely on predetermined parameters. The controller modifies assignment decisions adaptively by considering user-specified preferences such as desired occupancy levels and wait time tolerances, allowing the system to balance overall efficiency with individual user needs.
2Loss of time
If users make multiple fake requests for the same floor, then their individual travel time is reduced, but overall wait times and travel times for other passengers increase
Solution Approach 1:
The system implements feedback mechanisms where the controller monitors and analyzes request patterns from users. When duplicate or suspicious requests are detected, the system provides feedback to the user interface to prompt the user to cancel redundant requests. This feedback loop prevents fake requests from being processed, thereby maintaining overall system efficiency while still allowing legitimate urgent requests to be accommodated.
Solution Approach 2:
The system performs preliminary validation of requests by detecting user presence through sensors before processing the car assignment. By verifying that a user is actually present at the interface when making a request, the system prevents fake requests from being submitted in the first place, eliminating the need for subsequent detection and correction of erroneous requests.
3Quantity of substance
If fake requests are submitted to the destination management system, then car occupancy decreases, but wait times for genuine passengers increase
Solution Approach 1:
The system performs preliminary validation of requests by detecting user presence through sensors before processing the car assignment. By verifying that a user is actually present at the interface when making a request, the system prevents fake requests from being submitted in the first place, eliminating the need for subsequent detection and correction of erroneous requests.
