Night Vision Preserving Case for Electronic Device Flash
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cases and enclosures for electronic devices do not enable the use of a device's flash as a flashlight while preserving night vision, which is necessary for applications like aviation, hunting, and military operations.
Innovation Solution
A case with a cover member that filters light to a predominantly red or green spectrum, allowing the flash to function as a flashlight without impairing night vision, using materials like borosilicate glass or polymeric resins, and is designed to be releasably and slidably attached to the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the flash is used as a flashlight in low-light environments, then illumination is provided, but night vision is impaired
Solution Approach 1:
The patent applies color filtering by covering the flash with colored materials (red, green, or amber) that allow the flash to provide illumination while preserving night vision. The colored cover transforms the white light output of the flash into specific wavelength ranges that are less disruptive to night vision, thereby resolving the contradiction between providing illumination and preserving night vision capability
Solution Approach 2:
The patent introduces a colored cover as an intermediary element between the flash and the environment. This cover mediates the light output by filtering specific wavelengths while allowing sufficient illumination to pass through, thus enabling the flash to function as a flashlight without directly impairing night vision
2Object-affected harmful factors
If a secondary flashlight is carried for night vision preservation, then night vision is preserved, but device complexity increases
Solution Approach 1:
The patent makes the flash multi-functional by enabling it to serve both as a camera flash and as a flashlight with night vision preservation. By adding the colored cover, the flash gains the additional function of providing illumination in low-light conditions without requiring a separate flashlight device, thereby reducing overall system complexity
Solution Approach 2:
The patent merges the function of a separate night vision-preserving flashlight with the existing flash unit. The colored cover integrates night vision preservation capability into the flash itself, combining multiple functions (camera flash + illumination + night vision protection) into a single component
3Object-affected harmful factors
If the flash is covered to preserve night vision, then night vision is preserved, but illumination capability is reduced
Solution Approach 1:
The patent changes the spectral parameters of the light output by using colored filters that transmit specific wavelength ranges. The red, green, or amber covers alter the light spectrum to preserve night vision while maintaining sufficient illumination intensity through optimized material selection and design
