Solution Overview

Problem

Conventional mounting devices for electronic components in UAV helicopters are cumbersome, costly, and add weight due to individual rigid covers, which are sensitive to vibrations and harsh marine environments, making them impractical for lightweight and durable protection.

Innovation Solution

A mounting device comprising a solid, thermally conductive base plate with a flexible, waterproof cover connected via reversible means, such as zippers or snap fasteners, providing a compact, lightweight, and vibration-dampened solution for protecting electronic components from environmental stressors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If individual rigid covers are used to protect electronic components, then protection from environmental conditions is improved, but weight and device complexity increase significantly

Engineering Contradiction:

Improveprotection from environmental conditionsVSAvoidtotal weight of helicopter

Core Design Contradiction:

ReliabilityVSWeight of moving object

Solution Approach 1:

Multiple individual rigid covers for protecting electronic components are merged into a single flexible cover that envelops all components. This consolidation reduces the total number of protective elements from many separate covers to one unified cover, thereby reducing overall weight and simplifying the structure while maintaining protection against environmental conditions.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent replaces rigid covers with a flexible cover made of thin film material that can conform to the shape of the electronic components. This flexible cover provides environmental protection while being significantly lighter than conventional rigid covers, directly addressing the weight reduction goal.

Inventive Principle:

Principle #30Flexible shells and thin films

2Reliability

If individual rigid covers are used for each electronic component, then protection is provided, but the number of parts and installation complexity increase

Engineering Contradiction:

Improveprotection of electronic componentsVSAvoidnumber of covers and installation steps

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple individual protective covers into a single flexible cover that protects all electronic components simultaneously. This reduces the number of parts from many separate covers to one unified cover, and simplifies installation from multiple separate mounting operations to a single installation process.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The single flexible cover serves as a universal protective element for all electronic components, replacing the need for component-specific rigid covers. This multi-functional approach maintains protection for each component while eliminating the complexity of managing multiple specialized covers.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Strength

If rigid covers are used to protect electronic components, then structural strength is provided, but vulnerability to vibration and mechanical stress increases

Engineering Contradiction:

Improvestructural strength of coversVSAvoidresistance to vibration and mechanical stress

Core Design Contradiction:

StrengthVSReliability

Solution Approach 1:

The patent employs a flexible cover instead of rigid covers, allowing the protective element to deform and absorb vibration and mechanical stress rather than resisting it rigidly. This flexibility prevents the cover from becoming leaky or breaking under vibrational loads, thereby improving reliability in harsh operational environments.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The patent changes the key parameter of the cover from rigidity to flexibility. This parameter change transforms the cover's response to mechanical stress from brittle resistance to elastic deformation, enabling the cover to withstand vibration and mechanical stress without failure.

Inventive Principle:

Principle #35Parameter changes
