Solution Overview

Problem

Existing dust collection systems for concrete processing and other operations face challenges in providing reliable electrical power and effective dust extraction, especially in environments where conventional power sources are not available or pose health and safety risks, such as high carbon monoxide emissions from gas generators.

Innovation Solution

A mobile cart equipped with a propane engine-powered electrical generator and a multi-stage dust extraction and filtration system, including a HEPA filter, which provides both electrical power and dust collection capabilities, allowing for flexible operation modes and reducing harmful emissions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If a gas generator is used to provide electrical power, then power availability is improved, but carbon monoxide emissions and health safety risks worsen

Engineering Contradiction:

Improveelectrical power availabilityVSAvoidcarbon monoxide emissions

Core Design Contradiction:

Use of energy by moving objectVSObject-generated harmful factors

Solution Approach 1:

The patent combines the generator, dust collection system, and filtration system into a single integrated mobile cart unit. This merging allows the system to provide electrical power while simultaneously collecting and filtering dust and emissions at the source, resolving the contradiction between power availability and harmful emissions by combining both functions in one system.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The HEPA filtration system acts as an intermediary between the generator emissions and the surrounding environment. The filter captures and removes harmful particulates and carbon monoxide from the exhaust stream before release, mediating the harmful effects while maintaining power generation functionality.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If dust collection systems are used during concrete processing, then dust control is improved, but system complexity worsens

Engineering Contradiction:

Improvedust controlVSAvoidsystem complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The mobile cart is designed as a universal system that performs multiple functions: electrical power generation, dust collection, and emissions filtration. By consolidating these functions into one multi-functional unit, the system reduces overall complexity compared to having separate equipment for each function, while maintaining effective dust control.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Use of energy by moving object

If conventional power sources are used in indoor environments, then power supply is improved, but health and safety risks worsen

Engineering Contradiction:

Improvepower supplyVSAvoidhealth and safety risks

Core Design Contradiction:

Use of energy by moving objectVSObject-affected harmful factors

Solution Approach 1:

The HEPA filtration system serves as an intermediary that captures and removes harmful particulates and gases from the generator exhaust before they can affect indoor air quality. This allows safe operation of the power supply system in indoor environments by mediating the harmful effects through filtration.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A combination cart providing independent electrical power generation and dust extraction capabilities finds utility in concrete processing and other operations that create unwanted dust using hand tools for cutting, grinding, polishing, coring, drilling, sanding, and the like. A propane tank powers a propane engine, and the propane engine drives an electrical generator providing power to an electrical outlet panel mounted on the frame. The cart further includes a dust extraction and filtration system driven by an electric motor, also mounted on the frame. The inventive cart facilitates multiple modes of operation, including: (a) dust extraction and filtration only, with the dust extraction system being powered by an available external source of electrical power; (b) electrical power generation only, with the dust extraction and filtration system being turned off; and (c) simultaneous dust extraction/filtration and electrical power generation, with the dust extraction and filtration system being powered by the electrical generator.
