Solution Overview
Problem
Conventional globe display devices are limited in providing up-to-date geographical information and are unable to display information about multiple regions of the Earth simultaneously, making it difficult for users to compare data across different areas.
Innovation Solution
A globe display device featuring a spherical display unit with a hologram generating unit that uses a light source, polarization members, and a spatial light modulation unit to create three-dimensional holographic images, along with a control unit that manages user input and updates geographical information in real-time, allowing for the display of information from various regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a separate display device is used to show geographical information, then information can be displayed, but the display is limited to one region at a time and cannot provide real-time updated information
Solution Approach 1:
The patent transitions from a two-dimensional flat display to a three-dimensional spherical display unit. The spherical shape allows multiple regions of the Earth to be displayed simultaneously on its surface, enabling users to view and compare information from different regions without switching between separate displays. This dimensional change directly addresses the limitation of single-region display.
Solution Approach 2:
The spherical display unit serves multiple functions: it displays geographical information for multiple regions simultaneously, provides real-time updated information through connection to a server, and enables comparison of data across different areas. This multi-functionality resolves the contradiction by making a single device capable of handling multiple regions and information types.
2Loss of information
If conventional display devices are used, then simple time calculation information can be provided, but latest geographical information and multi-region data cannot be displayed
Solution Approach 1:
The patent combines the display function, information processing capability, and multi-region visualization into a single integrated spherical display device. The spherical display unit integrates multiple display areas on its surface, allowing it to show information from multiple regions simultaneously while maintaining a unified device structure, thus avoiding the need for multiple separate display devices.
3Ease of operation
If a spherical display unit with hologram generating unit is used, then holographic images of geographical information can be displayed, but the device complexity increases
Solution Approach 1:
The patent replaces traditional mechanical or electronic display mechanisms with a hologram generating unit that creates three-dimensional holographic images. This substitution allows users to interact with geographical information in a more intuitive and immersive manner, viewing data in 3D space rather than on a flat surface, thereby improving ease of operation despite the increased technological complexity.

Function Achieved in This Case
Enables the effective display of updated geographical information for all parts of the Earth as holographic images, enhancing user interaction and information comparison across multiple regions.
Implementation Method 1
a first polarization member configured to polarize the reference beam emitted from the light source at a first polarization angle to generate a polarized reference beam
Implementation Method 2
a spatial light modulation unit configured to realize a holographic interference pattern corresponding to holographic interference pattern data supplied from an outside, and reconstruct and play back a three-dimensional image (holographic image) utilizing diffracted components of the holographic interference pattern, which are generated according to diffraction of the polarized reference beam passing through the holographic interference pattern
Implementation Method 3
a second polarization member configured to polarize the diffracted components of the holographic interference pattern emitted from the spatial light modulation unit at a second polarization angle so as to remove a zero-order diffracted component from the diffracted components of the holographic interference pattern
