Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current nightlights for children do not adequately provide emotional comfort and security to improve sleep quality, as they lack innovative features to simulate a calming environment.
Innovation Solution
A projector apparatus with a rotating and translating inner lens and a fixed outer lens, combined with a light source and motor, projects a moving textured image on a ceiling to simulate a liquid surface, accompanied by soothing sounds, providing a 180-degree viewing angle and adjustable color emission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple light fixture is used, then the device complexity is low, but the emotional comfort and security provided to children is insufficient
Solution Approach 1:
The patent applies the dynamics principle by implementing a rotatable inner lens that oscillates back and forth to create moving textured images on the ceiling. This dynamic movement transforms a static light fixture into an engaging projection system that simulates liquid surfaces, thereby enhancing emotional comfort and security for children without requiring excessive complexity
Solution Approach 2:
The patent applies the dimensionality change principle by projecting two-dimensional textured images onto the three-dimensional ceiling space. The combination of lens rotation, translation, and optical projection creates immersive visual experiences that fill the room's vertical dimension, providing enhanced emotional comfort through spatial engagement
2Adaptability or versatility
If multiple lenses and moving parts are added to simulate liquid surface, then the emotional comfort is improved, but the device complexity increases
Solution Approach 1:
The patent applies the nesting principle by placing the inner lens inside the outer lens housing. The inner lens is rotatably mounted within the fixed outer lens structure, allowing compact integration of multiple optical components. This nested configuration enables complex visual effects while maintaining a space-efficient and manageable device structure
Solution Approach 2:
The patent applies the intermediary principle by using the inner lens as a mediator between the light source and the outer lens. The inner lens receives light from the source, rotates to create moving patterns, and projects them through the outer lens onto the ceiling. This intermediary mechanism enables sophisticated visual effects without requiring direct complex interaction between all system components
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
The apparatus effectively enhances emotional comfort and security for children, improving sleep quality by creating a calming and immersive environment that simulates a moving liquid surface, thereby addressing the need for improved emotional comfort and security at night.
Implementation Method 1
a light source configured to direct a portion of light through the rotatable and translatable inner lens and then through the concave outer lens
Implementation Method 2
the oscillating inner lens imparts a moving textured image for modification through the fixed concave outer lens for display upon a surface
Data Source
AI summary
A projector apparatus that may include a first plurality of adjacent translucent lenses on at least one side of an inner lens, said inner lens configured to rotate and translate about an axis (A) of the inner lens; a second plurality of adjacent translucent lenses formed on at least one side of a concave outer lens; a light source configured to direct a portion of light through the rotatable and translatable inner lens and then through the concave outer lens; and a motor configured to rotatably and translatably drive the inner lens in an oscillating manner about and along the axis of the concave inner lens (A); so that the oscillating inner lens imparts a moving textured image for modification through the fixed concave outer lens for display upon a surface, such as a ceiling to simulate a moving liquid surface.
