Solution Overview
Problem
Existing augmented reality systems lack the ability to dynamically reposition screen portions to create varying depths of viewing and enhance image resolution, limiting the interactive and immersive experience.
Innovation Solution
A system comprising movable knives, hooks, and linkages that allow for the repositioning of screen portions by moving nodes on an elastomeric or rigid screen, utilizing actuators and power sources to control multiple nodes with fewer motors, and incorporating comber boards to guide linkages and prevent entanglement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple projectors are used to create 3D scenes on a static screen, then image resolution and depth perception are improved, but device complexity and cost increase
Solution Approach 1:
The patent applies dynamics by transforming a static screen into a dynamic surface that can physically deform and reposition. The screen transitions from a fixed plane to an adaptable structure that can create varying depths and contours, allowing a single projector to achieve 3D effects that would otherwise require multiple projectors on a static surface.
Solution Approach 2:
The patent changes the physical parameters of the screen by introducing actuators that can alter the screen's shape, depth, and surface topology. By dynamically adjusting parameters such as screen curvature, elevation, and local deformation, the system enhances image resolution and depth perception without adding multiple projectors.
2Stability of the object's composition
If a rigid screen structure is used to maintain stability, then structural integrity is improved, but adaptability and dynamic repositioning capability deteriorate
Solution Approach 1:
The patent segments the screen into multiple independently controllable regions or segments. Each segment can be repositioned or deformed by its own actuator, allowing the screen to maintain overall structural integrity while enabling localized dynamic adjustments. This segmentation allows different parts of the screen to move independently, creating complex three-dimensional shapes from a structurally sound base.
Solution Approach 2:
The patent employs composite material structures that combine rigid and flexible properties. The screen uses composite construction to maintain structural integrity while incorporating elements that allow dynamic deformation and repositioning. This composite approach enables the screen to be both stable and adaptable simultaneously.
3Ease of operation
If more actuators and motors are added to control screen repositioning, then dynamic control capability is improved, but device complexity and cost increase
Solution Approach 1:
The patent implements multi-functionality by designing actuators and control mechanisms that serve multiple purposes. The same actuator system that repositions screen segments also maintains structural support, and the control system manages both positioning and shape transformation functions. This universal approach allows dynamic control without proportionally increasing device complexity.

Function Achieved in This Case
Enables dynamic repositioning of screen portions for enhanced depth and resolution, providing a more immersive augmented reality experience with improved control and reduced complexity and cost.
Implementation Method 1
the linkage pulls the node causing the portion of the elastomeric or rigid screen centered around the node to be moved distally away from a remaining portion of the elastomeric or rigid screen

AI summary
One aspect of the invention provides a system for dynamically repositioning a portion of a screen. The system includes: at least one knife moveable between a first position and a second position; a hook moveable between an open position in which the hook is disengaged from the at least one knife and a closed position in which the hook is removably engaged with the at least one knife; a node located on a back surface of the screen; and a linkage between the node and a distal end of the hook. When the hook is in the closed position and the at least one knife is moved from the first position to the second position, the linkage pulls the node causing the portion of the screen centered around the node to be moved distally away from a remaining portion of the screen.
