Light and Shadow Water Ball Structure with Grating Sheet Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water ball lamp decorations primarily focus on static visual effects and limited lighting, lacking dynamic projection capabilities to enhance visual appeal and decorative functionality.
Innovation Solution
A light and shadow water ball structure incorporating a seat body, a transparent three-dimensional water ball filled with a slightly thick flowable liquid, and a projector with a grating sheet and pattern, which projects light and shadow effects onto external objects using integrated light-emitting elements and a motor for liquid disturbance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a water ball lamp decoration uses static design and limited lighting, then the structure is simple, but the visual appeal and decorative functionality are insufficient
Solution Approach 1:
The patent combines multiple functions into a single integrated device: the water ball lamp decoration incorporates both traditional lighting functions and projection functions. The projector unit with grating sheet and light-emitting elements is integrated into the water ball structure, allowing the device to simultaneously provide ambient lighting and dynamic pattern projection, thereby enhancing visual appeal without requiring separate devices
Solution Approach 2:
The water ball lamp decoration is designed to perform multiple functions: it serves as both a traditional lighting source and a projection device. The grating sheet structure enables the same device to create various projection patterns while maintaining its lighting function, making the decoration versatile and adaptable to different decorative scenarios
2Adaptability or versatility
If dynamic projection effects are added to enhance visual appeal, then the decorative functionality is improved, but the device complexity increases
Solution Approach 1:
The projection system is segmented into distinct functional components: light-emitting elements, grating sheet with pattern, and projection lens. This segmentation allows each component to be optimized independently while maintaining overall system integration, making the complex projection functionality manageable and adaptable to different decorative needs
Solution Approach 2:
The water ball lamp decoration incorporates dynamic elements through the interaction of light with the flowable liquid and the projection mechanism. The projection patterns can be dynamically adjusted by changing the grating sheet configuration or light-emitting element positions, enabling the device to adapt to different decorative scenarios and enhance versatility
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 solution creates dynamic and changing projection effects, enhancing the visual appeal and decorative functionality of the water ball lamp by projecting patterns onto surfaces, offering a more engaging and interactive lighting experience.
Implementation Method 1
a first light-emitting element configured on a bottom of the projection passage
Implementation Method 2
the grating sheet having a pattern, and the pattern projected on an object outside the seat body through light emitted from the first light-emitting element
