Solution Overview

Problem

Existing methods fail to provide a reliable, repeatable, quick, and simple way to extract seized antenna elements from their housings, especially in environments where oxidation and particulate matter accumulation occur, leading to difficulties in damage-free removal.

Innovation Solution

A system comprising a support body, gripping mechanism, power transfer mechanism, camlock mechanism, threaded axis, and vibration mechanism is used to securely grasp and extract seized components, applying rotational force and vibrations to loosen oxidation and particulate matter, facilitating extraction with standardized and aligned forces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional extraction methods are used on seized components, then extraction can be attempted, but the success rate is low and damage to components is high

Engineering Contradiction:

Improveextraction success rateVSAvoidcomponent damage

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent employs a vibration mechanism that generates mechanical vibrations to loosen the seized component from its housing. The vibrations disrupt the oxidation and particulate matter bonding the component, reducing extraction force requirements and preventing damage while improving success rate

Inventive Principle:

Principle #18Mechanical vibration

Solution Approach 2:

The extraction system is divided into distinct functional modules: a gripping mechanism to secure the component, a power transfer mechanism to convert rotational to linear force, and a vibration mechanism to loosen bonds. This segmentation allows each component to be optimized independently for its specific function

Inventive Principle:

Principle #1Segmentation

2Force

If brute-force extraction methods are applied, then extraction force is maximized, but component damage increases and success rate does not improve significantly

Engineering Contradiction:

Improveextraction forceVSAvoiddamage-free extraction

Core Design Contradiction:

ForceVSReliability

Solution Approach 1:

Instead of applying brute-force extraction, the system uses controlled mechanical vibrations to progressively loosen the seized component. This reduces the peak extraction force needed while preventing damage through oscillatory motion that gradually breaks oxidation bonds

Inventive Principle:

Principle #18Mechanical vibration

Solution Approach 2:

The system changes the force application parameters from static high-force brute extraction to dynamic oscillatory vibration at specific frequencies. This parameter change allows force to be applied more effectively to break oxidation bonds without exceeding damage thresholds

Inventive Principle:

Principle #35Parameter changes

3Object-affected harmful factors

If weather seals are used to protect components, then protection from moisture is improved, but the seals break down over time and trap grime and oxidation

Engineering Contradiction:

Improvemoisture protectionVSAvoidseal durability

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent extracts the protection function from permanent weather seals and replaces it with an on-demand vibration-based extraction system. Rather than relying on seals that degrade over time, the system can be applied whenever extraction is needed to remove oxidation and particulate matter buildup

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A system and method for extracting seized components is disclosed. The method further grasping a seized component with a gripping mechanism and securing the gripping mechanism to the seized component by turning a camlock mechanism. A force is applied to a power transfer mechanism that moves a threaded axis that is threaded through the power transfer mechanism. The method additionally includes attaching the threaded axis to the gripping mechanism, which extracts the seized component. To facilitate extraction, the method also includes generating vibrations by a vibration mechanism, which may include a vibration mechanism rotating a rotary plate about a shaft. The method may also include generating vibrations by a cam attached to the rotary plate contacting one or more spring-loaded hammers. The spring-loaded hammers may be capable of impacting a strike plate, generating vibrations.
