Solution Overview

Problem

Conventional equipment mounting devices for vehicles, such as aircraft, are heavy due to metal materials, which decreases vehicle performance, and exposed antennas are susceptible to damage from passing objects.

Innovation Solution

A lightweight mounting device with a reinforced honeycomb structure made from materials like fiberglass and carbon fiber, providing additional strength through strategically placed reinforced portions and an aerodynamic seal, while minimizing weight and protecting equipment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If conventional metal mounting devices are used, then adequate support and strength are provided, but the overall weight of the vehicle increases decreasing vehicle performance

Engineering Contradiction:

Improvemounting device strengthVSAvoidvehicle weight

Core Design Contradiction:

StrengthVSWeight of moving object

Solution Approach 1:

The mounting device uses a composite structure combining foam core material with fiberglass reinforcement layers. The foam provides lightweight bulk while the fiberglass layers provide structural strength, achieving both weight reduction and adequate support capability

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

Fiberglass reinforcement is applied specifically at critical areas where strength is needed (mounting unit locations and areas between openings and mounting units) rather than uniformly throughout the entire structure, optimizing the strength-to-weight ratio

Inventive Principle:

Principle #3Local quality

2Adaptability or versatility

If exposed antennas are mounted on vehicles, then wireless communication connections are maintained, but the antennas are susceptible to being struck by passing objects

Engineering Contradiction:

Improvewireless communication capabilityVSAvoidphysical damage risk

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The radome is designed as an aerodynamic shell that encloses and protects the antenna equipment while allowing electromagnetic signals to pass through, providing physical protection without interfering with wireless communication functionality

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The antenna equipment is nested within the radome structure, with the mounting device providing an outer protective layer, creating multiple levels of protection while maintaining compact integration

Inventive Principle:

Principle #7Nested doll (Nesting)
