Solution Overview

Problem

Online reservation systems face issues where hosts' calendars are not updated, leading to guest reservations being refused or cancelled, causing frustration and lost revenue, as guests attempt to book properties that are not available, highlighting a need for reminders to maintain accurate calendar information.

Innovation Solution

A system that uses machine learning techniques, such as a decision tree model, to identify hosts who need calendar reminders based on their interaction patterns and send timely reminders to ensure calendars are up-to-date, preventing unnecessary cancellations and maintaining host engagement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the system sends frequent calendar reminders to hosts, then calendar accuracy improves, but host frustration and unsubscribe rates increase

Engineering Contradiction:
Improvecalendar accuracyVSAvoidhost engagement
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system performs preliminary analysis of host behavior patterns and calendar update needs before sending reminders. By predicting which hosts are likely to need reminders based on their historical behavior, the system sends reminders only to appropriate hosts at appropriate times, avoiding unnecessary communications that would frustrate hosts while still maintaining calendar accuracy for those who need it.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts reminder parameters such as frequency, timing, and targeting based on host behavior patterns. Instead of sending uniform reminders to all hosts, the system changes parameters like reminder interval and recipient selection based on individual host characteristics, thereby maintaining effectiveness while reducing host frustration.

Inventive Principle:
Principle #35Parameter changes

2Loss of time

If the system monitors and analyzes host interactions with calendars, then reminder timing accuracy improves, but system complexity increases

Engineering Contradiction:
Improvereminder timing accuracyVSAvoidsystem complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The system automatically monitors and analyzes host interactions with calendars without requiring external intervention. Hosts effectively 'teach' the system their behavior patterns through their natural interactions, and the system uses this self-generated data to improve reminder timing accuracy, eliminating the need for complex manual configuration or external data sources.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements feedback loops where host interactions with calendars are continuously monitored and fed back into the analysis model. This feedback mechanism allows the system to learn from actual host behavior and continuously improve reminder timing accuracy, with the feedback process being automatically integrated into the system operations rather than requiring separate complex analysis infrastructure.

Inventive Principle:
Principle #23Feedback

AI summary

Systems and methods for providing contextual calendar reminders are provided. A host can receive a calendar reminder notifying the host that a calendar for a property listing maintained by the host may need to be updated. The system can provide the host with a reminder to update the calendar for the property listing based on criteria related to the expected number of times the host will view the calendar within a designated time period and the timing of the host's last interaction with the calendar. If the designated criteria are satisfied, the system can generate a reminder for the host to update the calendar for the property listing. Before sending the reminder to the host, the system confirms that the host did not recently interact with the calendar and if the host did interact with the calendar, the system cancels the sending of the reminder.
