Visual ETA Marker for On-Time Arrival Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of portable electronic devices face difficulties in determining if they will arrive at a destination on time without calculating their current position and estimated time of arrival (ETA), as text-based ETA values do not provide clear visual cues for adjusting their travel speed to catch scheduled public transport or events.
Innovation Solution
An apparatus and method that display a visual marker, such as an ETA isoline or zone, on a map indicating whether the user is on time to reach a destination, allowing them to see if they need to speed up or are likely to arrive late, with dynamic updates based on current speed, traffic, and travel changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If text-based ETA values are displayed to users, then information about arrival time is provided, but users cannot quickly assess whether they will arrive on time without performing calculations
Solution Approach 1:
The patent creates a visual copy of the ETA concept by displaying a marker at the user's current position on the journey, rather than just showing text values. This visual copy allows users to immediately assess their punctuality status without calculations, resolving the contradiction between providing information and making it easy to understand.
Solution Approach 2:
The patent uses color coding (green for on-time, red for late) to visually represent the user's arrival status. This transforms abstract time information into intuitive visual cues, allowing users to quickly assess punctuality without performing calculations, thus resolving the contradiction.
2Ease of operation
If visual markers are displayed on a map, then users can quickly assess their arrival status, but the device complexity increases
Solution Approach 1:
The patent segments the journey into visual components by placing a marker at the user's current position on the map, separate from the destination. This segmentation creates a simple visual representation that shows progress without requiring complex calculations or displays, resolving the contradiction between ease of assessment and device complexity.
3Reliability
If the marker dynamically updates based on current speed and traffic, then the arrival status remains accurate, but the computational requirements and energy consumption increase
Solution Approach 1:
The patent implements periodic updates of the marker position based on current speed and traffic conditions, rather than continuous calculation. This periodic action maintains accuracy of the arrival status while reducing computational load and energy consumption, resolving the contradiction between reliability and energy use.
