Projected Decoration Light Cover for Clear Animated Figures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting decorations lack visual variation and decorative effect, with projected figures often blurry and unclear, and no significant difference in appearance when turned on or off.
Innovation Solution
A projecting decoration comprising an outer shell, light assembly, light-blocking cover, and controller, where the light-blocking cover has hollowed-out graphic portions and separating walls, allowing controlled light emission to project clear and varied figures on the outer shell, enhancing decorative effect and surprise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a film with patterns is mounted inside the shaped body to project figures, then the decorative effect is improved, but the contour of the projected figure becomes blurry and unclear
Solution Approach 1:
The light-blocking cover is divided into multiple independent light-blocking portions, each corresponding to a light unit. Each portion has a light-blocking surface with a graphic pattern that blocks light selectively, creating clear projected figures. The segmentation allows each portion to be optimized independently for sharp contours while maintaining overall decorative effectiveness.
Solution Approach 2:
Different portions of the light-blocking cover have different light-blocking properties tailored to their specific functions. The light-blocking surfaces are positioned and shaped to create specific graphic patterns in different locations, allowing each region to contribute uniquely to the overall clear projected figures while maintaining local optimization for contour clarity.
2Device complexity
If the lighting decoration uses a simple shaped body without additional components, then the device complexity is reduced, but the visual appeal when turned on and off becomes similar
Solution Approach 1:
The lighting decoration creates dynamic visual effects by controlling multiple light units to turn on and off in different patterns. The controller enables various lighting modes including sequential activation, random patterns, and synchronized operation, transforming a static structure into a dynamically appealing decoration that looks different when turned on versus off, and can even simulate animations.
Solution Approach 2:
The controller implements periodic lighting patterns where light units are activated in sequences or cycles. This creates rhythmic visual effects that enhance appeal variation, allowing the decoration to display different patterns at different times while maintaining a relatively simple overall structure without requiring complex mechanical moving parts.
3Area of stationary object
If multiple light units are used without separation, then the lighting coverage is improved, but the projected figures become blurry due to light interference
Solution Approach 1:
The light-blocking cover is segmented into multiple light-blocking portions, each associated with a specific light unit. Each portion selectively blocks light from its corresponding light unit while allowing light to pass through designated graphic patterns. This segmentation prevents light interference between adjacent units, maintaining clear projected figures across the entire lighting coverage area.
Solution Approach 2:
The light-blocking cover acts as an intermediary element between the multiple light units and the external environment. It mediates the light from each unit, directing it through specific graphic patterns while blocking interference from adjacent units. This intermediary structure enables broad lighting coverage while preserving the clarity of individual projected figures.

Function Achieved in This Case
The decoration achieves clear and varied projected figures with enhanced visual appeal, inciting a sense of surprise and fun by varying appearances when turned on and off, and can simulate animations.
Implementation Method 1
The light assembly emits light, the light passes through the light-blocking cover to project projected figures to the outer shell

AI summary
A projecting decoration comprises an outer shell, a light assembly, a light-blocking cover and a controller. The light assembly is mounted inside the outer shell. The light-blocking cover is mounted at the light assembly and has multiple hollowed-out graphic portions, which respectively correspond to multiple light units of the light assembly. The controller is electrically connected to and controls each light unit to emit light, which passes through corresponding hollowed-out graphic portion of the light-blocking cover to light up and project a projected figure to the outer shell. Because the controller controls a part of the multiple light units to turn on and another part to turn off, the outer shell shows various projected figures of different hollowed-out graphic portions corresponding to different light units, thereby enhancing a decorative effect of projecting decoration and inciting a sense of surprise and fun.
