Waterproof Light Scattering Member for Wearable Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable electronic devices face power consumption issues due to frequent display activation for notifications, especially with limited battery capacity in compact designs, leading to rapid battery draining.
Innovation Solution
Incorporating a light emitting structure with a waterproof member containing light scattering material, allowing for visual notifications without activating the display, thus reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the display is frequently activated for notifications, then the user can receive information, but the battery drains rapidly
Solution Approach 1:
The patent extracts the notification function from the main display system and implements it through a separate light emitting structure (LED). This allows notifications to be delivered through a dedicated light indicator that can operate independently with minimal power consumption, separating the information delivery function from the high-power display system.
Solution Approach 2:
The patent applies local quality by using a light scattering member positioned at a specific location (the first end of the housing) to scatter light locally for notification purposes. This localized light scattering mechanism provides visual notifications without requiring the entire display system to activate, thereby reducing overall power consumption while maintaining effective information delivery.
2Loss of information
If the display is used for all notifications, then comprehensive information can be shown, but power consumption increases unnecessarily
Solution Approach 1:
The patent creates a simplified copy of the notification function using a light emitting structure and light scattering member, rather than using the full display system. This copied notification mechanism provides sufficient visual information for alerts and notifications while consuming significantly less power than activating the complete display.
3Illumination intensity
If a waterproof member with light scattering material is added, then light can be scattered for visible notifications, but the device structure becomes more complex
Solution Approach 1:
The patent merges the waterproofing function and the light scattering function into a single integrated component. The waterproof member simultaneously provides water protection for internal components and scatters light for visible notifications, eliminating the need for separate waterproof and light scattering components, thus reducing overall structural complexity.
Solution Approach 2:
The waterproof member is designed with multi-functionality, serving both as a protective barrier against water and as a light scattering element for notification visibility. This universal component performs multiple functions (waterproofing + light scattering) that would otherwise require separate parts, thereby simplifying the overall device structure.

Function Achieved in This Case
The solution enables efficient battery power conservation by providing visual notifications through the light emitting structure, reducing the need for display activation and extending battery life in wearable devices.
Implementation Method 1
the waterproof member comprises light scattering material, wherein the light emitting structure is configured to emit light that is at least partially visible from outside through the waterproof member
