Filter Apparatus for Dynamic Light Shadow Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional projectors are limited to dark environments and struggle to reproduce natural fluctuations of light and shadow, such as those seen through tree leaves or on water surfaces, and are often expensive and large, restricting their usage.
Innovation Solution
A filter apparatus that includes a simulated object, a driving device to mechanically move the object, and a first lens to project light fluctuations onto an illumination surface, allowing for the reproduction of natural light and shadow patterns in bright environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a projector is used to project images, then projection function is achieved, but the device becomes expensive and large in size
Solution Approach 1:
The patent extracts only the essential projection function from a complete projector system by using a simple lens instead of a complex projector apparatus. This allows achieving projection capability without the expensive and large components of a full projector, resolving the contradiction between cost/size and projection functionality.
Solution Approach 2:
The patent creates a simplified copy of the projection function using basic optical components (lens and screen) rather than reproducing the entire projector system. This copied function achieves the desired effect at much lower cost and smaller size.
2Adaptability or versatility
If a projector is used in a bright environment, then usability is improved, but the projection image becomes insufficiently bright
Solution Approach 1:
The patent introduces a wind-blown simulated object that dynamically changes its position and shape in response to wind, creating dynamic shadow patterns on the screen. This dynamic element compensates for the lack of bright projected images by creating visually interesting fluctuating shadows that are visible even in bright environments.
Solution Approach 2:
The simulated object undergoes mechanical movement due to wind action, creating vibrating and fluctuating shadow patterns. This mechanical vibration of the object produces dynamic visual effects that enhance visibility and interest in bright environmental conditions where static projections would be imperceptible.
3Stability of the object's composition
If a projector reproduces the same image repeatedly, then consistent projection is achieved, but natural fluctuation of light and shadow cannot be reproduced
Solution Approach 1:
The patent replaces static image reproduction with dynamic shadow creation. The simulated object moves naturally in response to wind, creating continuously varying shadow patterns that reproduce natural fluctuations of light and shadow, eliminating the repetitiveness of static projector images.
Solution Approach 2:
The simulated object serves itself by using natural wind to drive its movement and shadow creation, eliminating the need for mechanical actuators or complex control systems. This self-driven system naturally produces non-repetitive, organic shadow patterns that mimic natural light fluctuations.

Data Source
AI summary
A filter apparatus is a filter apparatus that transmits light emitted by a light source (a lighting apparatus), and the filter apparatus includes a simulated object that receives the light emitted by the light source, a driving device that mechanically moves the simulated object, and a first lens that transmits the light emitted by the light source and having passed through the simulated object. The filter apparatus projects, onto an illumination surface, a projection image of fluctuation of light and shadow formed by the light emitted by the light source and having passed through the simulated object and the first lens.
