Solution Overview

Problem

Incidents such as safety incidents and personal conflicts can occur in travel coordination systems due to uncharacteristic user behavior, negatively impacting the transport experience.

Innovation Solution

A travel coordination system uses machine learning to identify uncharacteristic user states by analyzing user activity data during trip request entry, predicting user behavior, and adjusting trip parameters such as provider matching and location settings to mitigate potential issues.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the system monitors and analyzes user activity data to predict user state, then safety and reliability are improved, but device complexity and data processing requirements increase

Engineering Contradiction:
ImprovesafetyVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system performs preliminary analysis of user activity data before the actual trip occurs. By predicting user state in advance based on historical data patterns, the system can prepare appropriate responses beforehand, such as alerting providers or adjusting trip parameters, thereby improving safety without requiring complex real-time intervention systems

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system introduces an intermediary analysis layer that processes user activity data through machine learning models. This intermediary layer translates raw user behavior data into meaningful predictions about user state, acting as a mediator between data collection and safety response mechanisms, thus managing system complexity while improving reliability

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If the system collects and analyzes extensive user activity data, then prediction accuracy is improved, but loss of information and data privacy concerns increase

Engineering Contradiction:
Improveprediction accuracyVSAvoiddata privacy
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The system applies local quality analysis by examining specific aspects of user activity data that are most relevant to predicting user state, such as interaction patterns with the ride-sharing interface. Instead of analyzing all user data uniformly, the system focuses on locally relevant behaviors that indicate user state changes, thereby improving prediction accuracy while minimizing data processing scope and privacy risks

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system extracts only the necessary information from extensive user activity data to create prediction models. By extracting and analyzing only the specific data elements needed for state prediction (such as timing patterns, interaction sequences, and behavioral anomalies) rather than processing all available data, the system achieves accurate predictions while reducing data privacy concerns and information loss

Inventive Principle:
Principle #2Taking out (Extraction)

3Reliability

If the system adjusts trip parameters based on predicted user state, then safety is improved, but adaptability and responsiveness to user needs may be reduced

Engineering Contradiction:
ImprovesafetyVSAvoiduser needs responsiveness
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system implements dynamic trip parameter adjustments based on predicted user state. When a user is predicted to be in a high-risk state, the system dynamically modifies trip parameters such as selecting different providers, adjusting pickup/dropoff locations, or changing communication protocols. This dynamic adaptation improves safety while maintaining responsiveness to actual user needs through continuous monitoring and flexible parameter adjustment

Inventive Principle:
Principle #15Dynamics

AI summary

A system coordinates services between users and providers. The system trains a computer model to predict a user state of a user using data about past services. The prediction is based on data associated with a request submitted by a user. Request data can include current data about the user's behavior and information about the service that is independent of the particular user behavior or characteristics. The user behavior may be compared against the user's prior behavior to determine differences in the user behavior for this request and normal behavior of prior requests. The system can alter the parameters of a service based on the prediction about the state of the user requesting the service.
