Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional multi-resolution digital desk systems face space inefficiency and inflexibility due to fixed projection sources, which restrict the addition of new equipment and limit the display of high-resolution images, often causing the image to be obstructed by the user's arm.

Innovation Solution

A multi-resolution display system featuring a desktop display area, a foveal projection device, a sensor, and a manually adjustable fixture that allows the foveal projection device to be positioned freely above the desktop, enabling the detection of projected images and precise control of the projection device's orientation to display multiple high-resolution images without space limitations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If projection sources are placed on top or in front of the desk, then high-resolution images can be displayed, but the system takes up large space and images may be blocked by user's arm

Engineering Contradiction:

Improveimage resolutionVSAvoidsystem space

Core Design Contradiction:

Measurement precisionVSArea of stationary object

Solution Approach 1:

The patent inverts the conventional projection arrangement by placing projection sources below the desk surface instead of on top or in front. This inversion allows high-resolution images to be projected onto the desktop without occupying additional space above the desk and prevents user's arm from blocking the projection path.

Inventive Principle:

Principle #13The other way round (Inversion)

2Measurement precision

If projection sources are placed on top or in front of the desk, then high-resolution images can be displayed, but the system takes up large space

Engineering Contradiction:

Improveimage resolutionVSAvoidsystem structure

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent merges the projection source with the desk structure by integrating it into the desk's base or underside. This combining approach allows the projection system to function without occupying separate space above the desk, reducing overall system complexity while maintaining high-resolution display capability.

Inventive Principle:

Principle #5Merging (Combining)

3Measurement precision

If all high-resolution projection devices are fixed to specific positions, then stable projection is achieved, but it is impossible to display high-resolution images in other areas, reducing flexibility

Engineering Contradiction:

Improveimage resolutionVSAvoiddisplay flexibility

Core Design Contradiction:

Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent employs adjustable and movable projection devices that can be dynamically repositioned to different locations on or around the desk. This dynamic capability allows high-resolution images to be displayed in multiple areas while maintaining stable projection quality, thereby increasing system flexibility and adaptability.

Inventive Principle:

Principle #15Dynamics

4Area of stationary object

If projection equipment is integrated with the desk, then space is saved, but it is impossible to add new projection equipment

Engineering Contradiction:

Improvesystem spaceVSAvoidequipment expandability

Core Design Contradiction:

Area of stationary objectVSAdaptability or versatility

Solution Approach 1:

The patent segments the projection system into modular, independently adjustable components that can be added, removed, or repositioned. This segmentation allows the system to maintain a compact integrated form while enabling future expansion with additional projection equipment without requiring significant additional space.

Inventive Principle:

Principle #1Segmentation

AI summary

A multi-resolution display system including a desktop display area, a foveal projection device, a sensor, a control unit, and a manually adjustable fixture is provided. The desktop display area displays a central image and a low-resolution image. The control unit determines six-dimensional (6D) orientation information of the foveal projection device relative to the desktop display area according to a projected image detected by the sensor, so as to control the foveal projection device to project the central image within a target area on the desktop display area. The manually adjustable fixture fixes the foveal projection device on top of the desktop display area, and the movement of the manually adjustable fixture has a freedom of up to six dimensions.
