Solution Overview

Problem

Public transportation users face challenges with time wasted waiting for vehicles and uncertainty about arrival times, as current systems lack real-time transit delay information available on mobile devices prior to arrival at transit locations.

Innovation Solution

A method and device that determine the closest transit station to a user's position and display transit delay status based on relative priority, using location-based services and mobile devices to notify users of delays when relevant, minimizing unnecessary notifications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If real-time transit delay information is pushed to users continuously, then users receive comprehensive transit information, but users experience notification overload and device resource waste

Engineering Contradiction:

Improvetransit delay information availabilityVSAvoiddevice resource consumption

Core Design Contradiction:

Loss of informationVSLoss of energy

Solution Approach 1:

The system performs preliminary actions by determining user context (location, travel mode, destination) before generating notifications. This allows the system to pre-filter and prioritize transit delay information based on user relevance, ensuring that only meaningful notifications are pushed to the user's device, thus avoiding notification overload while maintaining information availability.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system applies local quality by customizing notification delivery based on user-specific context factors such as current location, transportation mode, and destination. Different users receiving the same transit delay information get different notification treatments - those actively waiting at a station receive prioritized alerts, while users not affected by the delay receive no notification, optimizing device resource usage.

Inventive Principle:

Principle #3Local quality

2Loss of information

If transit delay notifications are sent to all users, then all users receive transit information, but relevant users cannot be distinguished from irrelevant users

Engineering Contradiction:

Improvetransit delay information deliveryVSAvoidnotification relevance

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The system implements local quality by customizing notification delivery based on user-specific context factors such as current location, transportation mode, and destination. Different users receiving the same transit delay information get different notification treatments - those actively waiting at a station receive prioritized alerts, while users not affected by the delay receive no notification, optimizing device resource usage.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The system uses feedback mechanisms to continuously monitor user context (location, travel mode, destination) and adjust notification delivery accordingly. This dynamic feedback loop ensures that notifications are sent only when relevant to the user's current situation, allowing users to distinguish relevant from irrelevant notifications based on their personal context.

Inventive Principle:

Principle #23Feedback

3Loss of information

If comprehensive transit information is provided without prioritization, then all transit updates are delivered, but important delays are lost among minor updates

Engineering Contradiction:

Improvetransit information completenessVSAvoiduser attention time

Core Design Contradiction:

Loss of informationVSLoss of time

Solution Approach 1:

The system performs preliminary prioritization by analyzing user context (location, travel mode, destination) before delivering transit information. This preliminary action ranks notifications by relevance, ensuring that important delays affecting the user's specific situation are delivered first, while less relevant information is either delayed or omitted, preventing important updates from being lost among minor ones.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system applies partial action by selectively delivering only the most relevant transit information based on user context. Rather than providing all transit updates equally, the system delivers a prioritized subset of information that is most relevant to the user's current situation, saving the user's attention time while maintaining completeness of important information.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

Transit delay can be automated and pushed directly to a mobile device of a user based on a rank of usefulness within the mobile device interface. The closest transit station to a user's current position may be determined. An implementation may receive a current status of a transit delay in respect to the nearby transit station. A notification relating to the transit delay may be displayed on a mobile device of the user based on a relative priority of the notification, relative to other notifications available to be displayed on a mobile device of the user.
