Call Keep Function for Taxi Dispatch Flexibility

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing taxi call dispatch methods through mobile terminals do not provide drivers with sufficient options beyond accepting or rejecting calls, and lack information about the destination of the call, making it difficult for drivers to manage their routes effectively.

Innovation Solution

A call dispatch method and control server system that allows drivers to withhold decision-making on accepting or rejecting calls for a predetermined period, provides a call score to drivers based on historical data, and enables drivers to determine if new call information can be received after arriving at a destination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a driver is provided with only accept or reject options for call requests, then the system operation is simple, but the driver lacks flexibility in managing calls and route planning

Engineering Contradiction:

Improvedriver's flexibility in call managementVSAvoiddispatch system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a 'call keep' function that allows drivers to preliminarily reserve call requests without immediately accepting or rejecting them. This preliminary action phase enables drivers to hold calls for a predetermined period, providing flexibility to assess multiple factors before making a final decision, thus resolving the contradiction between driver flexibility and system complexity.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If call information is immediately assigned to drivers, then the dispatch efficiency is high, but drivers cannot plan routes effectively without destination information

Engineering Contradiction:

Improvedispatch efficiencyVSAvoiddestination information availability

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

The patent implements a feedback mechanism where the control server provides destination information to drivers through the call keep function. Drivers receive feedback about the destination before making their final acceptance decision, enabling effective route planning while maintaining dispatch efficiency through the structured call keep process.

Inventive Principle:

Principle #23Feedback

3Loss of time

If drivers make immediate decisions on call requests, then the response time is short, but drivers cannot evaluate multiple factors including future call possibilities

Engineering Contradiction:

Improvecall decision timeVSAvoiddriver's decision-making flexibility

Core Design Contradiction:

Loss of timeVSAdaptability or versatility

Solution Approach 1:

The call keep function creates a preliminary decision phase where drivers can reserve calls without immediate commitment. This preliminary action period allows drivers to evaluate multiple factors including potential future calls, while the predetermined time limit ensures the process doesn't excessively delay dispatch operations.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces dynamic time management to the call decision process. The call keep function operates with a predetermined time period that can be adjusted, allowing the system to adapt between quick dispatch (shorter keep period) and thorough evaluation (longer keep period), thus balancing response time with decision-making flexibility.

AI summary

A call dispatch method and server is provided, in which when call request information is transmitted from a user terminal to a control server, the control server may transmit the call information to one or more driver terminals in consideration of a call score and the like, and a driver may select a call keep function through a driver terminal, thereby withholding determination of whether to accept or reject a call for a predetermined time.
