Semi-Transparent Enclosure for Rear Projected Animated Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for animating decorative objects are costly and complex, lacking efficient solutions for projecting imagery onto objects in a way that is both customizable and interactive.
Innovation Solution
A system comprising a projector, mirror, and speaker housed within a semi-transparent or translucent enclosure, allowing for the projection of animated images onto the interior surface, which are visible from the exterior, with optional features like SD card storage, wireless communication, and sensors for interactive responses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If motors or other devices are used to animate the objects, then the decorative objects can be animated, but the cost and complexity increase
Solution Approach 1:
Instead of using complex motors to physically animate the decorative object, the patent projects animated images onto the surface of the object, creating a visual copy or representation of animation without the mechanical complexity. The object itself remains static while the projection system creates the animated effect on its surface.
Solution Approach 2:
The patent replaces mechanical animation systems (motors, actuators) with an optical projection system. Instead of physically moving parts to create animation, the system uses a projector to display animated images onto the object's surface, substituting mechanical complexity with optical and electronic components.
2Ease of manufacture
If a projector is positioned inside the enclosure to project onto the interior surface, then the image can be visible from the exterior, but the device complexity increases
Solution Approach 1:
The enclosure structure serves multiple functions: it provides the decorative housing, acts as the projection surface through its semi-transparent material, and contains the projection system. This multi-functionality reduces the need for separate components and simplifies the overall device structure.
Solution Approach 2:
The semi-transparent enclosure wall acts as an intermediary element that allows light to pass through while maintaining the decorative appearance. This intermediary property enables the projection system to function without requiring complex external mounting structures, as the enclosure itself becomes part of the optical path.
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
Enables cost-effective, customizable, and interactive animated displays on decorative objects, such as holiday decorations, with the ability to update content and respond to environmental stimuli, providing a user-friendly and engaging experience.
Implementation Method 1
a projector (such as an LED projector)... the projector projects an animation onto the interior surface of the enclosure
Implementation Method 2
Using the mirror, the projector projects an animation onto the interior surface of the enclosure

AI summary
A system may include an enclosure with an exterior wall that defines a cavity therein. The exterior wall may have an interior surface and an exterior surface. A projector support may be insertable into the cavity or may be formed as a single piece with the exterior wall such that the projector support supports a projector in a position and orientation in which the projector projects light at the interior surface from within the cavity. The exterior wall may have a thickness and material composition selected such that, in response to projection of light at the interior surface, an image is visible on the exterior surface.
