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

VSEngineering 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

Engineering Contradiction:
Improvecommunication capabilityVSAvoidinstallation complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #5Merging (Combining)

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Engineering Contradiction:
Improveaesthetic integrationVSAvoidcommunication performance
Core Design Contradiction:
ShapeVSReliability

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.

Inventive Principle:
Principle #7Nested doll (Nesting)

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

Engineering Contradiction:
Improveinformation deliveryVSAvoidview obstruction
Core Design Contradiction:
Loss of informationVSObject-affected harmful factors

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.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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.
