Multi-projection System Using Interior Surfaces as Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 3D projection systems require additional screens around audience seats, making it difficult to implement a multi-projection system in theaters with only a single screen without remodeling the existing structure, which can be impractical due to installation challenges and internal structural limitations.
Innovation Solution
A multi-projection system that utilizes interior surfaces such as walls, floors, and ceilings as projection surfaces, enhanced with a coating layer to improve optical properties and a management device to synchronize and correct images projected on these surfaces, allowing for synchronized image projection without additional screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional screens are installed around audience seats to create a multi-projection system, then the 3D effect and audience immersion are improved, but the device complexity and installation difficulty increase significantly
Solution Approach 1:
The patent applies universality by making existing theater infrastructure (walls, floors, ceilings) serve dual purposes: their original structural function and as projection surfaces. This eliminates the need for separate additional screens while achieving multi-projection system functionality, directly resolving the contradiction between improving 3D effect quality and reducing system complexity
Solution Approach 2:
The patent merges the projection function with existing theater interior surfaces by applying special coatings to walls, floors, and ceilings. This combines the structural elements into a unified multi-projection system, eliminating the need for separate screen installations and reducing overall system complexity while maintaining immersive 3D quality
2Adaptability or versatility
If additional screens are installed in a completed theater, then multi-projection capability is achieved, but the ease of manufacture and installation deteriorate due to remodeling requirements
Solution Approach 1:
The patent applies preliminary action by pre-applying special optical coatings to interior surfaces during theater construction or renovation phases. This prepares the surfaces in advance to function as projection surfaces, eliminating the need for complex additional screen installations later while achieving multi-projection capability
Solution Approach 2:
The patent makes existing interior surfaces universal by enabling them to serve both their original structural purposes and as projection surfaces through coating application. This approach achieves multi-projection capability without requiring separate screen installations, dramatically improving installation ease in completed theaters
3Ease of operation
If interior surfaces are used as projection surfaces without coating, then the ease of operation is improved, but the image quality and optical properties deteriorate due to heterogeneity
Solution Approach 1:
The patent applies parameter changes by modifying the optical properties of interior surfaces through special coatings that control reflectance, absorption, and light scattering characteristics. This ensures consistent image quality across different projection surfaces while maintaining the simplicity of using existing structures, resolving the contradiction between ease of operation and image quality consistency
Solution Approach 2:
The patent applies local quality by applying different coating formulations or thicknesses to different interior surfaces (walls, floors, ceilings) based on their specific optical requirements and viewing angles. This ensures each surface has optimized optical properties for its location, achieving uniform image quality across all projection surfaces while keeping the system simple to operate
