Notification Light Assembly Using Segmented Waveguides
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in distinguishing between different types of visual notifications due to the limited range of colors and patterns that can be emitted by notification lights, leading to uncertainty about the nature of alerts, potentially causing important communications to be missed.
Innovation Solution
A light assembly comprising separate light sources for a background and patterned portions, using waveguides and pattern elements to create distinguishable visual notifications, allowing for a combination of colors and patterns to provide contextual alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-color or limited-color LED notification light is used, then the device structure remains simple and power consumption is low, but the ability to distinguish between different notification types is insufficient
Solution Approach 1:
The notification light is divided into multiple independent light-emitting regions, each capable of emitting a specific color or pattern. This segmentation allows different notification types to be represented by different colored segments, enhancing differentiation capability while maintaining a relatively simple overall structure.
Solution Approach 2:
Different regions of the notification light are assigned different colors or emission characteristics tailored to specific notification types. This local quality approach allows each region to serve a specific function, improving the ability to distinguish between different alert categories without requiring a completely complex system.
2Loss of information
If multiple light colors and patterns are used to represent different notification types, then notification differentiation is improved, but the device complexity and power consumption increase
Solution Approach 1:
The notification light system dynamically adjusts which light-emitting regions are activated based on the type of notification received. Instead of all regions being constantly active, only the necessary segments are illuminated, reducing power consumption while maintaining full differentiation capability when needed.
Solution Approach 2:
The system changes operational parameters (which specific light regions are active) based on the notification type. This allows the same physical hardware to convey multiple types of information by varying the activation state of different segments, maintaining information richness without proportionally increasing power consumption.
3Object-affected harmful factors
If visual alerts are used instead of audible or physical alerts, then user disruption is reduced, but the ability to convey detailed notification information is limited
Solution Approach 1:
The notification light transitions from a single-dimensional (single color or uniform pattern) alert system to a multi-dimensional system where different spatial segments can emit different colors or patterns simultaneously. This dimensional expansion allows visual alerts to convey more detailed information about notification types, urgency, and categories while maintaining the non-disruptive visual modality.
