Projection-Based Decorative Lamp with Segmented Chambers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing decorative lamps lack entertainment value and variability in their lighting effects, primarily due to limited interaction and shadow manipulation capabilities.
Innovation Solution
A projection-based decorative lamp with a translucent plastic shell, featuring multiple projection chambers and light sources that alternate to project dynamic shapes onto the shell, enhancing interaction and shadow variation, including a pumpkin design with open and closed mouth effects and eye and nose projections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single light source and shape hole are used, then the device complexity is low, but the lighting effect variability and entertainment value are insufficient
Solution Approach 1:
The projection assembly is divided into multiple independent projection chambers (first projection chamber, second projection chamber, third projection chamber), each with its own light source and shape hole. This segmentation allows independent control of each projection, enabling diverse lighting effects and patterns while maintaining manageable complexity through modular design
Solution Approach 2:
The patent introduces multi-dimensional projection by positioning light sources and shape holes at different vertical and horizontal locations. The first light source projects forward, the second light source projects downward, and the third light source projects upward, creating three-dimensional lighting effects on the pumpkin shell that enhance variability and entertainment value
2Adaptability or versatility
If multiple projection chambers with different light source positions are used, then the interaction and shadow variation are enhanced, but the device complexity increases
Solution Approach 1:
The projection assembly is divided into multiple independent projection chambers (first projection chamber, second projection chamber, third projection chamber), each with its own light source and shape hole. This segmentation allows independent control of each projection, enabling diverse lighting effects and patterns while maintaining manageable complexity through modular design
Solution Approach 2:
The patent introduces multi-dimensional projection by positioning light sources and shape holes at different vertical and horizontal locations. The first light source projects forward, the second light source projects downward, and the third light source projects upward, creating three-dimensional lighting effects on the pumpkin shell that enhance variability and entertainment value
3Adaptability or versatility
If alternating light sources are used to create dynamic shapes, then the amusement and playfulness are enhanced, but the control system complexity increases
Solution Approach 1:
The control circuit board implements periodic alternating control of the light sources, switching between first light source and second light source, and between first and third light sources. This periodic action creates dynamic shape projections that change over time, enhancing amusement and playfulness through rhythmic illumination patterns
Solution Approach 2:
The control circuit board with preset mode programs automatically manages the alternating light source sequences without requiring complex user intervention. The system self-regulates the projection patterns through predefined modes, reducing the perceived control complexity while maintaining dynamic effects
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 significantly enhances amusement and playfulness by creating dynamic and interactive light and shadow effects, suitable for various environments and occasions, such as festivals, by alternating projected shapes and intensifying the ambiance.
Implementation Method 1
The first light source illuminates the first shape hole to project a first shape onto the decorative shell
Implementation Method 2
the first light source illuminates the first shape hole to project a first shape onto the decorative shell

AI summary
A projection-based decorative lamp includes a decorative shell made of a translucent plastic material, and includes a projection assembly, the projection assembly being provided inside the decorative shell. A first projection chamber and a second projection chamber are provided within the projection assembly; the first projection chamber includes a first shape hole formed on a front wall and a first light source formed on a rear wall, and the second projection chamber includes a second shape hole formed on a front wall and a second light source formed on a rear wall; the first light source illuminates the first shape hole to project a first shape onto the decorative shell, and the second light source illuminates the second shape hole to project a second shape onto the decorative shell; a center point of the first shape is the same as a center point of the second shape.
