Solution Overview

Problem

Mobile kitchens face challenges with heat buildup, noise, and smoke production due to trapped heat and uncontrolled combustion from open flame burners, particularly in confined spaces and hot climates, leading to uncomfortable working conditions and potential health hazards.

Innovation Solution

The design incorporates air channels around appliances to isolate excess heat and noise, using blowers to vent heat and smoke outside, and features double-walled exhaust channels and strategically positioned blowers to maintain a cooler workspace while ensuring efficient combustion with distillate fuel burners.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If cooking appliances with open flame burners are used in a mobile kitchen, then cooking functionality is provided, but heat and noise are trapped within the confined space raising temperature to over 49°C

Engineering Contradiction:
Improvecooking functionalityVSAvoidworkspace temperature
Core Design Contradiction:
Ease of operationVSTemperature

Solution Approach 1:

The patent extracts the harmful heat and noise from the workspace by routing exhaust gases through channels in the trailer walls away from the kitchen area. The combustion products are diverted outside the confined space, removing the thermal burden from the workspace while preserving the cooking function.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces air channels and blowers as intermediary elements between the combustion sources and the workspace. These channels act as conduits to transport hot exhaust gases away from the kitchen area, while the blowers provide forced ventilation to maintain acceptable temperature levels in the workspace.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If open flame burners are used for cooking, then cooking is enabled, but smoke, noxious gases, and carbon build-up are produced and trapped within the trailer

Engineering Contradiction:
Improvecooking capabilityVSAvoidsmoke and noxious gases
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The patent extracts harmful combustion products (smoke, noxious gases, carbon) from the workspace by channeling them through exhaust pathways in the trailer walls. This removal prevents accumulation of harmful substances within the confined kitchen space while maintaining open flame cooking capability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent implements continuous ventilation through blowers that operate to maintain constant air exchange in the workspace. This continuous action ensures that harmful gases are continuously removed and fresh air is supplied, preventing carbon build-up and maintaining air quality during cooking operations.

Inventive Principle:
Principle #20Continuity of useful action

3Adaptability or versatility

If all appliances are arranged within a trailer for mobility, then the kitchen is mobile, but space is confined causing heat to remain trapped

Engineering Contradiction:
ImprovemobilityVSAvoidtrailer internal temperature
Core Design Contradiction:
Adaptability or versatilityVSTemperature

Solution Approach 1:

The patent extracts heat from the confined trailer space by creating dedicated exhaust channels that route hot gases outside the trailer. This allows the kitchen to remain mobile and confined while preventing heat accumulation through external venting pathways.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent addresses the three-dimensional heat trapping problem by creating vertical and lateral exhaust pathways through the trailer structure. The air channels extend in multiple dimensions (through walls, roof, or sides) to provide efficient heat removal from the confined internal space.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Ease of operation

If open flame burners are used, then cooking is possible, but uncontrolled excess noise is produced within the confined space

Engineering Contradiction:
Improvecooking functionVSAvoidnoise
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent extracts noise from the workspace by routing exhaust gases through channels that lead away from the kitchen area. The combustion noise and burner sounds are channeled outside the trailer or to areas away from the workspace, reducing noise exposure for users while preserving cooking functionality.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A mobile kitchen comprises a housing disposed atop one or more wheel axles and a plurality of appliances disposed within the housing. Each appliance is heated by combustion of a distillate fuel. One or more air channels are disposed about each of the appliances, such that each air channel substantially isolates excess heat from combustion of the distillate fuel from a workspace within the housing. One or more first air blowers are associated with the air channels, and each is adapted to force air through the air channels and vent the excess heat to the exterior of the housing. One or more second air blowers are coupled to the housing, and each second air blower is adapted to vent a predetermined volume of air from within the workspace at least once per minute.
