Innovation Solution
An LED night light with projection features that utilizes multiple LEDs and various optics means such as lenses, grating, and holograms to project images onto ceilings, walls, or floors, allowing for adjustable positioning and focus, enabling the creation of clear and engaging images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional night lights are used, then the device is simple and inexpensive, but the device lacks the ability to project images or messages onto surfaces
Solution Approach 1:
The patent combines multiple functional components (LED light source, optics means including lenses and holograms, and projection mechanism) into a single integrated night light device. This merging allows the device to perform both traditional illumination and image projection functions, resolving the contradiction between simplicity and versatility.
Solution Approach 2:
The night light device is designed to perform multiple functions: providing ambient illumination and projecting images or messages onto surfaces. This multi-functionality directly addresses the contradiction by enabling the simple device to gain projection capabilities through the integration of optics means and projection mechanisms.
2Illumination intensity
If multiple LEDs and optics means are used to project images, then the image quality and visual engagement are improved, but the device complexity increases
Solution Approach 1:
The optics system is segmented into distinct functional components: multiple LED light sources for illumination, separate optics means (lenses, holograms) for image formation, and projection mechanisms. This segmentation allows each component to be optimized independently while maintaining overall system manageability, resolving the contradiction between image quality and complexity.
Solution Approach 2:
The patent utilizes parameter changes in the optics system, such as adjusting focal lengths of lenses, varying LED illumination intensity, and changing projection distances, to optimize image brightness and clarity. These parameter adjustments enable high-quality image projection without requiring overly complex fixed structures.
3Adaptability or versatility
If adjustable positioning and focus features are added, then the projection flexibility and image quality are improved, but the ease of operation decreases
Solution Approach 1:
The patent incorporates adjustable positioning features that allow the projection mechanism to be dynamically repositioned to different locations and angles. This dynamic adjustability provides projection flexibility while maintaining reasonable ease of operation through intuitive mechanical adjustments rather than complex electronic controls.
