Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing commercial systems for cleaning flooring and extracting water from water-damaged buildings are energy-intensive and noisy, particularly due to the need to pressurize and heat cleaning water, and there is a need for improved efficiency and reduced noise levels, especially in residential settings.
Innovation Solution
A vehicle-based system that incorporates a separate on-board power system with a heat exchanger and muffler configuration, where the heat exchanger uses exhaust gases to preheat cleaning fluid and the muffler attenuates noise by absorbing sound energy within a fluid supply tank, reducing energy consumption and noise levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a separate internal combustion engine is used to power the pump and blower, then sufficient power is available for pressurizing and heating cleaning water, but energy consumption increases and noise levels rise
Solution Approach 1:
The patent combines the exhaust gas heat exchanger and muffler into a single integrated assembly that serves both heating and noise reduction functions. The exhaust gases pass through a heat exchanger that transfers thermal energy to the cleaning water, while simultaneously the muffler attenuates noise from the engine and exhaust system. This merging of functions reduces overall system complexity and improves energy efficiency by utilizing waste heat that would otherwise be lost.
2Power
If a separate internal combustion engine is used to power the pump and blower, then sufficient power is available for pressurizing and heating cleaning water, but noise levels increase
Solution Approach 1:
The patent converts the harmful exhaust gases and noise into beneficial functions. The hot exhaust gases, which would normally be wasted heat and pollution, are directed through a heat exchanger to preheat the cleaning water, reducing the energy required for heating. Simultaneously, the exhaust flow passes through a muffler that attenuates noise, transforming the noisy exhaust into a quiet, preheated water supply system.
3Loss of energy
If heat exchangers are used to extract heat from the engine, then energy efficiency improves, but device complexity increases
Solution Approach 1:
The patent merges the heat exchanger and muffler into a single integrated assembly that performs both heat recovery and noise attenuation functions. The exhaust gas pathway is routed through the heat exchanger first, transferring thermal energy to the cleaning water, then the cooled exhaust gases pass through the muffler for noise reduction before being expelled. This integrated design achieves energy efficiency without proportionally increasing system complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system achieves improved energy efficiency and reduced noise levels, with the heat exchanger effectively preheating cleaning fluid and the muffler significantly lowering sound levels, from around 120 dB to less than 90 dB, enhancing operational efficiency and user experience.
Implementation Method 1
a heat exchanger that receives a flow of exhaust gas from an exhaust outlet of the extraction engine and that heats a flow of pressurized air or preheats water supplied to the extractor
Implementation Method 2
the heat exchanger uses exhaust gases to preheat cleaning fluid
Implementation Method 3
a muffler that transmits the flow of exhaust gas and that transmits the flow of pressurized air or water to thereby reduce the sound level produced by the system
