Modular Light Assembly for Wearable Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices face challenges in providing a reliable external light source without draining the device's battery, especially during physical activities and exposure to liquids, as existing solutions often rely on the device's display for illumination.
Innovation Solution
A modular light assembly that integrates with wearable devices, featuring discrete light sources with independent control, a dedicated battery, and liquid-resistant design, allowing for separate illumination from the device's display and secure attachment to both the device housing and band.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the wearable device's display is used for illumination, then a light source is provided, but the device's battery is drained
Solution Approach 1:
The illumination system is segmented into two independent parts: the device's display illumination and the modular light assembly's dedicated light sources. Each has its own power source, allowing the modular light sources to provide additional illumination without draining the device's battery.
Solution Approach 2:
The illumination function is extracted from the device's display system and placed into a separate modular light assembly with its own battery. This extraction allows independent operation of the light sources without affecting the device's battery power.
2Reliability
If the modular light assembly is designed to be secure and water-resistant, then reliability is improved, but device complexity increases
Solution Approach 1:
The attachment mechanism merges two functions: securing the modular light assembly to the device housing and securing it to the band. This single mechanism provides both attachment points, simplifying the overall design while ensuring secure and reliable mounting in various orientations.
Solution Approach 2:
The connection mechanism is designed with universal functionality to attach to both the device housing and the band simultaneously. This multi-functional design achieves reliable securement without requiring separate attachment systems for each location.

AI summary
A modular light assembly is designed for integration with wearable devices. For example, the modular light assembly can connect with a wearable device, such as a smartwatch, including both a device housing and a band of the wearable device. Additionally, the modular light assembly can receive communication from the wearable device through various means, including inductive energy transfer. As a result, the modular light assembly can receive communication from the wearable device to activate (turn on) or deactivate (turn off) one or more light sources of the modular light assembly. Additionally, or alternatively, the modular light assembly device may include a button coupled to a switch that can activate or deactivate the light source(s).
