Solution Overview

Problem

Multi-screen cinemas face issues with space utilization, image deformation, and inconsistent viewer angles due to the high placement of projectors, leading to suboptimal viewing experiences, especially in smaller rooms.

Innovation Solution

A cinema room design featuring a cylindrical sector projection screen tilted 5-10 degrees and a projector integrated within the seating area, oriented 80-100 degrees towards the screen's center, allowing for improved light utilization and minimizing image deformation, while ensuring uniform horizontal vision across all seats.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If the projector is placed high above the seating area, then the projection covers the entire screen, but the image becomes deformed and the viewing angles vary significantly for different seats

Engineering Contradiction:

Improvescreen coverage areaVSAvoidimage deformation

Core Design Contradiction:

Area of stationary objectVSManufacturing precision

Solution Approach 1:

Instead of placing the projector high above the screen as in conventional cinemas, the patent inverts the arrangement by positioning the projector at the same level as the screen, integrated within the seating area. This inversion eliminates the need for long-distance projection and associated image deformation while maintaining full screen coverage.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent transitions from a vertical projection arrangement (projector above screen) to a horizontal arrangement (projector at screen level). This dimensional change allows the projector to be integrated within the seating area while maintaining optimal projection geometry and eliminating perspective distortion.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Area of stationary object

If the projector is placed high above the seating area, then the projection reaches the screen, but the space utilization is reduced due to projection cabins and corridors

Engineering Contradiction:

Improvescreen projection areaVSAvoidusable cinema space

Core Design Contradiction:

Area of stationary objectVSVolume of moving object

Solution Approach 1:

The patent merges the projector location with the seating area by integrating the projector within the tiers of seats at the same level as the screen. This eliminates the need for separate projection cabins and access corridors, thereby maximizing the usable volume of the cinema room.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

By inverting the conventional vertical projection arrangement and adopting a horizontal arrangement with the projector at screen level, the patent eliminates the need for elevated projection platforms and rear projection cabins, thus increasing the usable space for seating and circulation.

Inventive Principle:

Principle #13The other way round (Inversion)

3Area of stationary object

If the projector is placed high above the seating area, then the projection covers the screen, but the light utilization is limited and dual projectors are needed for large screens

Engineering Contradiction:

Improvescreen sizeVSAvoidprojector light utilization

Core Design Contradiction:

Area of stationary objectVSUse of energy by moving object

Solution Approach 1:

By inverting the projection geometry from high-angle vertical projection to horizontal projection at screen level, the patent enables the projector beam to strike the screen perpendicularly. This maximizes light utilization efficiency and eliminates the need for dual projectors or complex mirror systems even for large screens.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent changes the projection angle parameter from a high angle (conventional) to a perpendicular angle (horizontal projection). This parameter change optimizes light utilization efficiency and allows single-projector coverage of large screens without requiring additional optical elements.

Inventive Principle:

Principle #35Parameter changes

4Area of stationary object

If the projector is placed high above the seating area, then the projection is achieved, but the horizontal vision angle varies for different seats

Engineering Contradiction:

Improveprojection areaVSAvoidviewing consistency

Core Design Contradiction:

Area of stationary objectVSEase of operation

Solution Approach 1:

By inverting the conventional arrangement and placing the projector horizontally at the same level as the screen rather than vertically above it, the patent ensures that all seats at the same level have identical horizontal vision angles, providing consistent viewing experience throughout the auditorium.

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

Arrangement for a cinema room for a multi-screen cinema, in which each of the cinema rooms has a film projector (1), a screen (2) and tiers of seats (3) with multiple rows of seats (3a, 3b,..., 3n) arranged to different heights. Said screen (2) has a surface in form of a cylindrical sector with a constant curvature, being inclined towards the stands forming an angle (a) with a vertical line comprised between 5º and 10º and in that the film projector (1) is integrated in an intermediate area of the tiers of seats (3), oriented towards the centre of the screen (1), forming with the screen (2) an angle (b) comprised between 80º and 100º.
