Electronic Watch Display Device with Retrograde Hand for Schedule Time Remaining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices do not effectively display remaining time for scheduled events, lacking intuitive and timely notifications for users, especially when schedules are far in the future or approaching.
Innovation Solution
A display device, such as an electronic watch, that acquires and displays schedule information including starting and ending times, using hands and digital displays to show remaining time, with a retrograde hand indicating time remaining and digital countdowns for closer end times, and automatic updates via wireless communication with a terminal device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If schedule information is displayed only when events are imminent, then users receive timely notifications for approaching events, but users miss notifications for future events that are far in advance
Solution Approach 1:
The display device dynamically adjusts its notification behavior based on the time remaining until scheduled events. It transitions between different display modes: showing only approaching events when they are imminent, and showing both approaching and future events when they are farther away. This dynamic adaptation resolves the contradiction by optimizing notification timing while maintaining information completeness across different time contexts.
Solution Approach 2:
The system changes the parameter of time threshold for displaying schedule information. When the current time is earlier than a first reference time, it displays events within a first time threshold. When the current time is between the first and second reference times, it expands to display events within a second, longer time threshold. This parameter adjustment allows the system to provide comprehensive notifications for future events while maintaining timely notifications for approaching events.
2Loss of information
If the display shows detailed schedule information continuously, then users have complete information about all events, but the display becomes cluttered and hard to read
Solution Approach 1:
The display device segments schedule information based on time urgency and user interest. It separates approaching events from future events, and further segments them based on time thresholds. This segmentation allows the display to show only relevant information in each context, maintaining readability while providing complete information when needed. The information is organized in a hierarchical manner that prioritizes readability without losing data completeness.
Solution Approach 2:
The display dynamically adjusts the amount and type of schedule information shown based on the current time context. It transitions between displaying only approaching events, displaying both approaching and future events, and showing detailed versus summary information. This dynamic adjustment ensures the display remains clean and readable while providing complete schedule information according to the user's current needs and time context.
3Loss of information
If the device displays both approaching and future schedule events, then users get comprehensive schedule overview, but the display becomes complex and less intuitive
Solution Approach 1:
The display device applies different display qualities and formats to different types of schedule events. Approaching events are displayed with one level of detail and prominence, while future events are displayed with a different level of detail. This local quality differentiation allows the display to provide comprehensive schedule coverage while maintaining simplicity and intuitiveness by treating different event types according to their specific characteristics and user relevance.
Data Source
AI summary
A display device includes at least one processor and a display. The processor acquires one or a plurality of pieces of schedule information each including information of a starting time and information of an ending time and causes the display to display a time remaining between a present time and the starting time or a time remaining between the present time and the ending time.
