Rotating Illumination Assembly for Smartphone Camera Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smartphones lack adequate illumination for their front-side cameras, especially in low-light conditions, and existing accessories often increase the size and form factor by providing separate illumination for both front and back cameras, failing to meet the need for interchangeable and high-intensity lighting.
Innovation Solution
A protective case with a built-in illumination assembly that includes LEDs, a reflector, and a lens, capable of rotating to direct light towards either the front or back camera, powered by a battery pack, allowing for adjustable lighting intensity and usage as a standalone flashlight, controlled via an app or directly through the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If separate illumination devices are provided for front-side and backside cameras, then adequate illumination for both cameras is achieved, but the size and form factor of the accessory increases significantly
Solution Approach 1:
The patent combines two separate illumination devices into a single integrated illumination assembly that can serve both the front-side and backside cameras. The illumination assembly includes a housing with a first opening for the front-side camera and a second opening for the backside camera, allowing one device to provide illumination for both cameras instead of requiring two separate devices.
Solution Approach 2:
The illumination assembly is designed with multi-functionality to serve multiple purposes: it provides illumination for the front-side camera through the first opening, illumination for the backside camera through the second opening, and can function as a standalone flashlight. This universal design eliminates the need for separate dedicated illumination devices for each function.
2Illumination intensity
If a fixed illumination device is provided for the front-side camera, then adequate illumination for selfies is achieved, but illumination for the backside camera is not provided
Solution Approach 1:
The illumination assembly is designed to be dynamic rather than fixed, allowing it to adapt to different usage scenarios. The housing can be positioned or configured to direct illumination toward the front-side camera when needed for selfies, and toward the backside camera when needed for traditional photography, enabling a single device to replace multiple dedicated illumination devices.
3Illumination intensity
If a fixed illumination device is provided for the backside camera, then adequate illumination for traditional photographs is achieved, but illumination for the front-side camera is not provided
Solution Approach 1:
The illumination assembly is designed to be dynamic rather than fixed, allowing it to adapt to different usage scenarios. The housing can be positioned or configured to direct illumination toward the front-side camera when needed for selfies, and toward the backside camera when needed for traditional photography, enabling a single device to replace multiple dedicated illumination devices.

Data Source
AI summary
A protective case for an electronic device is disclosed. The protective case may also provide a light source to be used with the front-side camera and the backside camera of the electronic device. The light source may pivot between different positions in order to emit light in the proper direction. The protective case may also include at least one power source to power the electronic device as well as the light source.
