Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Massive multiple input and multiple output antenna arrays pose installation challenges in publicly accessible areas due to their size, affecting the appearance and requiring additional mechanical fixing for displays, which can hinder the impression of the space and increase complexity.
Innovation Solution
A device comprising a stereoscopic display system with an adjustable horizontal parallax barrier (AHPB) and a detector, using motion sensors or radar to position the display effectively, allowing for holographic images to be presented to observers while integrating with the MMIMO antenna array, enabling power and data sharing, and allowing the system to be compact and aesthetically integrated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a stereoscopic display is installed in a publicly accessible area to communicate with persons without suitable terminals, then communication capability is improved, but the installation complexity and mechanical fixing requirements increase
Solution Approach 1:
The patent combines the stereoscopic display system with the MMIMO antenna array housing, integrating multiple functions (communication and display) into a single structure. This eliminates the need for separate mechanical fixing of display equipment and reduces installation complexity while maintaining communication capability with persons lacking suitable terminals.
Solution Approach 2:
The antenna array housing serves dual purposes: it provides structural support for the MMIMO antennas and simultaneously houses the stereoscopic display system. This multi-functional design allows the same structure to enable both wireless communication and visual information delivery to persons without terminals, reducing overall system complexity.
2Shape
If the antenna array size is reduced to improve appearance in publicly accessible areas, then aesthetic integration is improved, but the MMIMO communication performance deteriorates
Solution Approach 1:
The stereoscopic display system is nested within the existing antenna array housing structure. This allows the display to be accommodated without increasing the overall external dimensions of the antenna array, maintaining aesthetic integration while providing additional communication functionality through the display for persons without terminals.
3Loss of information
If the display is made visible to present stereoscopic images to observers, then information delivery is improved, but the view of the antenna array is obstructed
Solution Approach 1:
The display presents stereoscopic images in a third dimension (depth) using holographic or augmented reality techniques, allowing information to be delivered above or around the antenna array structure rather than on a flat surface that would block the view. This enables simultaneous visibility of both the display content and the antenna array behind it.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a compact, aesthetically pleasing display that can present different stereoscopic images to observers at various positions without obstructing the view of the antenna array, while maintaining MMIMO radio communication capabilities and optimizing power usage by entering sleep mode when unoccupied.
Implementation Method 1
The AHPB is for example adjustable on basis of liquid crystal display, LCD, elements
Implementation Method 2
The detector is a motion sensor, a radar sensor adapted to determine the position of the observer from a radar signal reflected by the observer
