Modular Notification Service for Real-Time Event Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In various industries, including travel and hospitality, there is a need for efficient notification systems that inform customers about changes in their interactions, such as appointment cancellations or reservation modifications, and allow for immediate alterations based on this information.
Innovation Solution
A modular system comprising a services layer and application layer that communicates with client devices, utilizing a notification service module to detect events, determine appropriate actions, and deliver messages through various channels like email, SMS, or voice, ensuring timely and preferred communication methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a notification system delivers immediate real-time notifications to customers about event changes, then customer satisfaction and loyalty are enhanced, but system complexity and resource consumption increase
Solution Approach 1:
The system is divided into distinct modular components: event sources that generate events, a notification service that processes events, delivery engines that send notifications, and client devices that receive them. This segmentation allows each component to be independently developed, maintained, and scaled, reducing overall system complexity while enabling reliable real-time notifications.
Solution Approach 2:
The notification service acts as an intermediary layer between event sources and delivery engines. It receives events from various sources, determines appropriate actions through rules or algorithms, and routes notifications to suitable delivery channels. This mediator pattern decouples the system architecture, making it more manageable and flexible.
2Adaptability or versatility
If multiple communication channels (email, SMS, voice) are supported for notifications, then customer reach and preference satisfaction improve, but device complexity and implementation difficulty increase
Solution Approach 1:
The notification service is designed as a universal platform that handles multiple communication channels (email, SMS, voice, push notifications) through a unified architecture. The same core notification logic can route messages to different delivery engines based on customer preferences or event type, eliminating the need for separate systems for each channel and reducing implementation complexity.
Solution Approach 2:
The system uses configurable parameters to control notification behavior across different channels. Customer preferences, event types, and delivery rules are stored as adjustable parameters that can be modified without changing the underlying system architecture, allowing flexible adaptation to different communication needs while maintaining system simplicity.
3Loss of information
If the system processes and delivers notifications in real-time, then information timeliness improves, but processing speed requirements and resource consumption increase
Solution Approach 1:
The notification system uses event-driven periodic processing where notifications are generated and delivered based on specific triggering events rather than continuous processing. The notification service polls event sources or receives event push notifications, processes them according to configured rules, and delivers them through appropriate channels. This event-triggered periodic action ensures timely information delivery while avoiding the resource waste of continuous processing.
Data Source
AI summary
A system and method for notifying a notification recipient of an event status change and allowing the notification recipient to request action is disclosed. An event occurs. A message relating to the event applicable to an end-user is created. A communication link between an outbound module and a device associated with the end-user is established. The message is delivered to the end-user device. The communication link is transferred from the outbound module to an inbound module. A response is received from the end-user device at the inbound module.
