LED Status Indicator for Mobile Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of mobile electronic devices face frustration when trying to determine the device's status, such as locked or unlocked mode, without having to focus on the screen, as existing methods require visual attention and are not readily available.
Innovation Solution
A method and apparatus using a set of LEDs around a trackball to provide visual, audible, and tactile indications of the device's status, including ring volume settings, by illuminating with specific colors and intensities corresponding to the status, allowing users to quickly determine the device's state without looking at the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If users look at the display screen to determine device status, then they can obtain accurate information, but they must divert attention from other tasks and focus intensely on the screen
Solution Approach 1:
The patent segments the device status information display by separating it from the main display screen. Different status types (locked, password mode, unlocked) are mapped to distinct colored lights (red, yellow, green) that can be perceived at a glance without requiring user focus on the screen, thus resolving the contradiction between information access and attention continuity.
Solution Approach 2:
The patent uses color changes as a visual indicator system where different colors represent different device statuses. The colored lights provide immediate, intuitive status information that users can detect peripherally or at a glance, eliminating the need to divert attention to the display screen and maintaining task continuity.
2Loss of information
If the device provides detailed status information on the display screen, then users can obtain comprehensive device state data, but the information is not readily available without staring intently at the screen
Solution Approach 1:
The patent implements preliminary action by continuously monitoring device status and pre-mapping it to corresponding colored light indicators. The status information is prepared and displayed in advance through the color-coded light system, so when users need to check status, the information is already available immediately without requiring time to analyze display screen content.
Solution Approach 2:
By encoding device state information in color changes, the patent creates an immediate visual cue system. Users can determine status in seconds by glancing at the colored light rather than spending time reading or interpreting detailed information on the display screen, thus reducing time loss.
3Productivity
If users attempt to use the device without verifying status due to concentration on tasks, then speed and ease of use are maintained, but frustration occurs when the device is in locked mode
Solution Approach 1:
The patent implements feedback by providing real-time visual information about device status through colored lights. Users receive immediate feedback about whether the device is locked, in password mode, or unlocked, allowing them to adjust their usage accordingly without frustration. This maintains both productivity and reliability by preventing failed usage attempts.
Solution Approach 2:
The color-coded feedback system provides intuitive, immediate information about device usability. Red indicates locked status, yellow indicates password mode, and green indicates unlocked status, allowing users to quickly understand device state and adjust their actions, maintaining both speed and reliability of usage.
