Solution Overview

Problem

Existing antenna placement methods are not aesthetically pleasing and face resistance from communities, with single pole designs limiting antenna placement options and mechanical stability, especially in residential and urban areas.

Innovation Solution

A multi-trunk antenna structure with a main trunk and multiple upper trunks that extend outwardly, allowing for adjustable antenna placement and cable routing, resembling natural tree structures to conceal antennas and enhance aesthetics, while providing increased mechanical stability through modular design and smooth cable raceways.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If single pole antenna structures are used, then installation is simple and cost is low, but aesthetic appeal deteriorates and community acceptance decreases

Engineering Contradiction:

Improveinstallation simplicityVSAvoidaesthetic appeal

Core Design Contradiction:

Ease of manufactureVSShape

Solution Approach 1:

The single pole structure is segmented into multiple trunks branching from a central support, allowing antennas to be distributed across multiple arms while maintaining structural simplicity. This segmentation transforms the单调 single pole into a multi-branch structure that resembles natural tree forms, improving aesthetics without complicating installation

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The antenna support structure copies natural tree forms (such as oak or eucalyptus trees) by arranging multiple trunks and branches in organic patterns. This copying of natural aesthetics makes the structure visually acceptable to communities while maintaining the functional simplicity of engineered support structures

Inventive Principle:

Principle #26Copying

2Device complexity

If single pole antenna structures are used, then structural simplicity is maintained, but mechanical stability in high winds deteriorates

Engineering Contradiction:

Improvestructural simplicityVSAvoidmechanical stability

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The structure divides the single pole into multiple trunks and branches, distributing wind loads across multiple structural elements rather than concentrating them on one pole. This segmentation enhances mechanical stability by reducing the impact of high winds while maintaining overall structural simplicity through modular construction

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The structure transitions from a one-dimensional single pole to a three-dimensional multi-trunk configuration with branches extending in multiple directions. This dimensional change provides better aerodynamic characteristics and wind resistance while maintaining structural efficiency

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If more antennas are placed to increase coverage, then wireless communication capability improves, but aesthetic appeal and community acceptance worsen

Engineering Contradiction:

Improvewireless communication capabilityVSAvoidaesthetic appeal

Core Design Contradiction:

Adaptability or versatilityVSShape

Solution Approach 1:

Multiple antennas are segmented and distributed across multiple trunks and branches rather than clustering them on a single pole. This segmentation allows for increased wireless coverage capacity while the distributed arrangement mimics natural tree branching patterns, preserving aesthetic appeal

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The multi-trunk structure serves multiple functions simultaneously: it provides support for multiple antennas to enhance communication capability, maintains aesthetic appeal through naturalistic design, and offers cable routing pathways within trunk cavities. This multi-functionality resolves the contradiction between capability enhancement and aesthetic preservation

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Ease of operation

If cable routing is done through traditional methods, then installation is straightforward, but cable management and protection deteriorate

Engineering Contradiction:

Improveinstallation easeVSAvoidcable protection

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

Cables are nested within hollow cavities inside the trunks and branches, protecting them from environmental damage and physical interference. This nesting approach maintains installation ease by providing pre-formed cable pathways while significantly improving cable protection and management compared to external routing methods

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

A multi-trunk antenna structure that includes a main trunk and a plurality of upper trunks is provided. The upper trunks extend upwardly at a desired angle from the main trunk and provide a desired girth of the structure near the top. A plurality of antennas are attached to desired upper trunks at a desired height above ground level. The antennas can be adjusted to a desire azimuth. The antenna structure can include branches so that it resembles a Eucalyptus tree, an Oak tree, or other type of tree. The trunks of the structure can provide raceways for antenna cabling.
