Solution Overview

Problem

Existing satellite communication antennas integrated into aircraft are not adaptable to different models and often interfere with the aircraft's structure, leading to increased drag and limited functionality.

Innovation Solution

A modular antenna support system that allows for the reception of different antenna models by changing only the base and ring components, with guiding, driving, and determining means mounted externally to minimize interference and reduce drag.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the antenna support is integrated into the antenna structure, then the structural stability is improved, but the adaptability to different antenna models deteriorates

Engineering Contradiction:
Improvestructural stabilityVSAvoidadaptability to different antenna models
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The antenna support system is divided into modular components: a base unit with guiding means, driving means, and determining means, and a separate ring unit with antenna securing means. This segmentation allows the ring and antenna to be detached and reconfigured for different antenna models while the base remains stable and reusable, thus maintaining structural stability while improving adaptability.

Inventive Principle:
Principle #1Segmentation

2Stability of the object's composition

If the antenna support is integrated into the aircraft structure, then the structural stability is improved, but the drag increases

Engineering Contradiction:
Improvestructural stabilityVSAvoiddrag
Core Design Contradiction:
Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The antenna support system is extracted from the aircraft's internal structure and positioned as an external modular unit. The ring with antenna securing means can be mounted on the aircraft exterior, separating the antenna system from the main aircraft structure. This reduces interference with the aircraft's aerodynamic profile and minimizes drag while maintaining the stability of the antenna positioning system.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of manufacture

If the antenna support components are mounted internally, then the structural integration is improved, but the interference with aircraft structure increases

Engineering Contradiction:
Improvestructural integrationVSAvoidinterference with aircraft structure
Core Design Contradiction:
Ease of manufactureVSObject-generated harmful factors

Solution Approach 1:

The ring acts as an intermediary component between the aircraft structure and the antenna. It provides a dedicated mounting interface for the antenna while being guided by the base unit, which interfaces with the aircraft. This intermediary ring structure eliminates direct interference between the antenna and aircraft structure, allowing easy manufacturing and assembly while preventing structural interference.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Adaptability or versatility

If the antenna support has large dimensions to accommodate different antennas, then the adaptability is improved, but the drag increases

Engineering Contradiction:
Improveaccommodation of different antenna dimensionsVSAvoiddrag
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The ring diameter can be varied to match different antenna sizes, creating a dynamic configuration system. The base unit with guiding means remains constant, but the ring component can be exchanged or adjusted to accommodate different antenna dimensions. This dynamic adaptability allows the system to fit various antenna sizes without requiring a permanently large support structure, thus minimizing drag while maintaining versatility.

Inventive Principle:
Principle #15Dynamics
