Solution Overview
Problem
Existing electronic devices face challenges in distinguishing between different types of visual notifications due to limited color ranges of LED lights, leading to uncertainty about urgent communications, which may result in missed important events.
Innovation Solution
A light assembly comprising separate light sources for background and patterned portions, using waveguides and pattern elements to create distinguishable visual cues, allowing for a combination of colors and patterns to indicate different notification types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multi-color LED is used for visual notifications, then the device can provide visual alerts with different colors to signify different event types, but the customization is limited by the limited range of colors that can be emitted
Solution Approach 1:
The notification light is divided into two separate components: a background light portion and a patterned light portion. The background light provides the base color indication, while the patterned light overlay provides additional differentiation through distinct patterns (e.g., solid, blinking, pulsing). This segmentation allows the system to convey more notification types than color alone could provide, effectively increasing customization without requiring an expanded color palette.
2Loss of information
If different light colors are used to distinguish notification types, then visual alerts can indicate different event types, but it becomes difficult to distinguish one color from another in bright sunlight
Solution Approach 1:
By segmenting the visual notification into background color and foreground pattern components, the system ensures that the pattern element remains distinguishable even when color differentiation is compromised by ambient light. The patterned portion (e.g., blinking vs. solid, pulsing vs. steady) provides a secondary distinction mechanism that is less susceptible to washout by sunlight compared to subtle color variations.
Solution Approach 2:
The system uses contrasting color combinations between the background light and patterned light to maximize visibility. The patterned light portion is designed to stand out against the background, creating visual contrast that maintains distinguishability under various lighting conditions including bright sunlight.
3Loss of information
If different blinking rates are used to distinguish notification types, then visual alerts can indicate different event types, but it becomes difficult to distinguish one rate from another without careful examination
Solution Approach 1:
The notification system segments the visual information into two layers: background color indication and foreground pattern indication. Instead of relying solely on blinking rate variations, the patterned light portion introduces distinct spatial and temporal patterns (e.g., solid vs. blinking vs. pulsing vs. alternating) that are more easily distinguishable. This segmentation reduces the cognitive load required to differentiate between notification types.
4Device complexity
If a single light source is used for notifications, then the device structure remains simple, but several varieties of the same event type are lumped together making it difficult to determine the specific event
Solution Approach 1:
The light assembly is segmented into a background light source and a patterned light source, allowing independent control of each component. This enables the system to convey multiple layers of information: the background color indicates the general event category, while the patterned overlay specifies the particular event type. This segmentation increases information capacity without requiring a proportional increase in overall system complexity.
Solution Approach 2:
The dual-component light assembly serves multiple functions: the background light provides color-based categorization, while the patterned light provides pattern-based specification. Together, they create a universal notification system that can handle diverse event types using a unified approach, rather than requiring separate dedicated lights for each notification type.
