Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current handheld electronic device accessories lack integrated rear electroluminescent lighting to enhance visual optics in low-light environments, leading to eye strain and reduced image clarity.
Innovation Solution
A handle with an integrated electroluminescent system that diffuses white light from the back perimeter of the device to the front screen, using LEDs powered by rechargeable batteries and featuring an on/off dimmer switch, providing bias lighting without direct glare.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If handheld electronic device accessories lack integrated rear electroluminescent lighting, then device simplicity is maintained, but visual optics are reduced in low-light environments causing eye strain and reduced image clarity
Solution Approach 1:
The patent combines the handle accessory with an integrated electroluminescent lighting system, merging two separate functions (mechanical support and illumination) into a single unified device. The handle structure houses LED light sources, power management circuitry, and battery components, creating a combined accessory that provides both ergonomic support and bias lighting functionality.
Solution Approach 2:
The handle accessory serves multiple functions simultaneously: it provides mechanical support for holding the device, offers adjustable positioning via pivot mechanisms, and delivers electroluminescent lighting for screen visibility enhancement. This multi-functional design eliminates the need for separate lighting accessories and basic holders.
2Reliability
If integrated electroluminescent lighting is added to enhance screen visibility, then image clarity improves, but device complexity increases
Solution Approach 1:
The lighting system is segmented into modular components: multiple LED light sources distributed around the handle, separate power management circuitry, rechargeable battery cells, and control switches. This segmentation allows for easier manufacturing, maintenance, and replacement of individual components without affecting the entire system.
Solution Approach 2:
The patent introduces a diffuser element as an intermediary between the LED light sources and the device screen. This diffuser mediates the light output by scattering and softening the illumination, preventing direct glare while maintaining enhanced screen visibility. The diffuser acts as a buffer that transforms the harsh LED output into gentle bias lighting.
3Object-affected harmful factors
If rear bias lighting is implemented to reduce eye strain, then ambient light balance improves, but direct glare may occur without proper diffusion
Solution Approach 1:
The patent introduces a diffuser element as an intermediary between the LED light sources and the device screen. This diffuser mediates the light output by scattering and softening the illumination, preventing direct glare while maintaining enhanced screen visibility. The diffuser acts as a buffer that transforms the harsh LED output into gentle bias lighting.
Solution Approach 2:
The lighting system implements local quality control by positioning LED light sources at specific locations around the handle and using individual diffusers for each light source. This allows different regions of the lighting system to have optimized characteristics - some areas provide stronger illumination while others provide softer, more diffuse light - creating an overall balanced lighting environment that reduces eye strain without causing glare.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution reduces eye fatigue and increases perceived image clarity by establishing a balanced ambient light, improving screen visibility in dark environments without causing glare or reflections.
Implementation Method 1
The invention also has an integrated electroluminescent system (96) that diffuses white light from the elongated oval handle around the back perimeter of the electronic device to the front screen viewing area
Implementation Method 2
The illuminating light source maybe a plurality light panel of LED's (96) built in the angular side with a reflective edge (106) of the handle (76)
Implementation Method 3
The electroluminescent lighting source may derive its power from rechargeable batteries (116) located inside the handle

AI summary
A portable assembly includes a multi-positional attachable handle with a plurality of integrated light emitting diodes (LEDs) within a perimeter of a reflective angled side edge of the handle which produces a back-light illumination. A white light emitting device is attached directly to a back of a smart phone, an iPad or a laptop product. The handle also functions as a stand assembly for holding a hand-held portable electronic device or a smartphone in a multitude of positions or locations. A first section of the device includes a pivot ball base that is attached to the back of the electronic device itself or it's case. A method of radiating light from behind an object during a darkened or low light viewing environment is called “Bias Lighting”.
