Event Participation Status Routing for Selective User Notifications

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing event management systems lack user convenience in managing participation applications, lottery drawing, and message transmission for face-to-face events, particularly in competitive games using physical cards.

Innovation Solution

An event management device and system that includes a management unit to track user status, a notification unit to send messages, and a control unit to manage and control these functions, enabling efficient user status management and message notification based on user status changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the system sends notifications to all users regardless of their status, then all users receive information, but system load and network traffic increase unnecessarily

Engineering Contradiction:

Improveuser convenienceVSAvoidsystem load

Core Design Contradiction:

Ease of operationVSLoss of energy

Solution Approach 1:

The notification unit sends notifications selectively based on user status. Different user statuses (participant, non-participant, winner, non-winner) receive different notification treatments. This local differentiation reduces unnecessary network traffic and system load while ensuring relevant users receive appropriate notifications.

Inventive Principle:

Principle #3Local quality

2Loss of time

If the system allows users to access event information before their status is confirmed, then users can plan ahead, but system load increases due to premature access attempts

Engineering Contradiction:

Improveuser planning timeVSAvoidsystem load

Core Design Contradiction:

Loss of timeVSLoss of energy

Solution Approach 1:

The control unit performs preliminary status determination before allowing access to event information. Users must first have their status confirmed (participant/non-participant, winner/non-winner) before the notification unit sends relevant event information. This preliminary filtering prevents premature access attempts while still allowing users sufficient time to plan according to their confirmed status.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If the system manages user status in multiple stages with selective notifications, then user convenience improves, but device complexity increases

Engineering Contradiction:

Improveuser convenienceVSAvoidsystem complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The management unit divides user status into distinct segments: participant/non-participant and winner/non-winner. The notification unit then sends targeted notifications based on these segmented statuses. This segmentation approach manages complexity by creating clear, discrete status categories rather than continuous complex states, making the system easier to implement and maintain.

Inventive Principle:

Principle #1Segmentation
