Solution Overview

Problem

Existing payload retrieval apparatuses in uncrewed vehicles face issues with dirt and debris accumulation, which can affect their functionality and efficiency, and there is a need for effective cleaning mechanisms.

Innovation Solution

A cleaning structure is deployed on a tether from an aerial vehicle and drawn through the payload retrieval apparatus, featuring flexible cleaning components that engage interior surfaces to remove dirt and debris, and can deliver cleaning solutions or lubricants as it moves through the channel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a cleaning structure is deployed on a tether to clean the payload retrieval apparatus, then cleaning effectiveness is improved, but device complexity increases

Engineering Contradiction:
Improvecleaning effectivenessVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The cleaning structure is divided into separate functional components: a main body for structural support, flexible cleaning components (brushes, cloths, or sponges) for contact cleaning, and optional fluid delivery systems. This segmentation allows each component to perform its specific function efficiently while simplifying the overall design and maintenance of the cleaning system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cleaning structure is designed to perform multiple cleaning functions simultaneously - mechanical cleaning through flexible components that contact interior surfaces, and chemical cleaning through fluid delivery systems that apply cleaning solutions. This multi-functionality improves cleaning effectiveness while avoiding the need for separate cleaning systems for different types of contamination.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Area of stationary object

If flexible cleaning components are used to fit into crevices, then cleaning coverage is improved, but manufacturing precision requirements increase

Engineering Contradiction:
Improvecleaning coverageVSAvoidmanufacturing precision
Core Design Contradiction:
Area of stationary objectVSManufacturing precision

Solution Approach 1:

The cleaning structure employs flexible cleaning components such as brushes, cloths, or sponges that can deform and conform to the irregular interior surfaces and crevices of the payload retrieval apparatus. This flexibility allows the cleaning components to reach into tight spaces and complex geometries without requiring precise manufacturing tolerances, thereby maximizing cleaning coverage while maintaining reasonable manufacturing standards.

Inventive Principle:
Principle #30Flexible shells and thin films

3Area of stationary object

If the cleaning structure is drawn through the apparatus on a tether, then accessibility to interior surfaces is improved, but operation complexity increases

Engineering Contradiction:
Improveaccessibility to interior surfacesVSAvoidoperation complexity
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The cleaning structure is designed to be self-contained with all necessary cleaning components (mechanical elements, fluid reservoirs, delivery mechanisms) integrated into a single unit that can be deployed independently on a tether. The structure cleans itself as it is drawn through the payload retrieval apparatus, eliminating the need for external操作 or complex deployment mechanisms, thereby improving accessibility while maintaining ease of operation.

Inventive Principle:
Principle #25Self-service

AI summary

A cleaning structure for a payload retrieval apparatus includes a main body having an upper end and a lower end. The upper end includes a tether attachment point. The cleaning structure also includes a first cleaning component extending outward from the main body. The first cleaning component has a flexible construction for fitting into crevices in the payload retrieval apparatus and defines a cleaning zone around the main body.
