Collapsible Windscreen Assembly for Stable Portable Cooking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable cooking gear used for outdoor activities such as camping and backpacking is often inefficient and unreliable due to exposure to adverse weather conditions, leading to flameouts and increased cooking times, which require extra fuel and weight in backpacks.
Innovation Solution
A windscreen designed for portable cooking gear that protects the flame from wind, rain, and cold temperatures, improving heat transfer and retention while allowing controlled airflow to maintain the flame, and can be disassembled for compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If portable cooking gear is used without protection from adverse weather conditions, then the equipment remains lightweight and compact, but the flame is exposed to wind and rain causing flameouts and heat loss
Solution Approach 1:
The windscreen is divided into multiple panels that can be assembled together to form a protective enclosure around the flame and cooking vessel, providing weather protection while maintaining a relatively simple overall structure
Solution Approach 2:
The windscreen serves multiple functions: it protects the flame from wind and rain, provides structural support for the cooking vessel, and reflects heat back to the pot to improve heating efficiency, thereby reducing the need for additional specialized components
2Reliability
If a windscreen is added to protect the flame from adverse weather conditions, then flame stability and heat transfer efficiency improve, but the weight and bulk of the cooking assembly increase
Solution Approach 1:
The windscreen utilizes thin, flexible material that provides effective weather protection and heat reflection while minimizing the weight and bulk added to the cooking assembly, making it suitable for backpacking and outdoor activities
Solution Approach 2:
The windscreen is constructed from composite materials that combine weather resistance, heat reflection properties, and lightweight characteristics, optimizing the balance between protection and portability
3Reliability
If the windscreen is designed to protect the flame from wind and rain, then flameouts are prevented, but airflow to the flame may be restricted
Solution Approach 1:
The windscreen incorporates porous or mesh sections that allow controlled airflow to reach the flame while still providing protection from wind and rain, ensuring adequate oxygen supply for combustion without compromising flame stability
4Weight of moving object
If conventional portable cooking gear is used, then the equipment is lightweight and portable, but cooking times are extended due to heat loss to the environment
Solution Approach 1:
The windscreen captures and redirects heat that would otherwise be lost to the surrounding environment back toward the cooking vessel, converting harmful heat loss into beneficial heat retention, thereby reducing cooking time without requiring additional fuel weight
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 windscreen enhances cooking efficiency by preventing flameouts, reducing cooking times, and minimizing fuel consumption, while maintaining the warmth of cooked food, all while maintaining portability and compactness.
Implementation Method 1
improving heat transfer from the fuel source to the cooking vessel
Implementation Method 2
keeps the contents of the cooking vessel warmer for longer by thermally insulating the cooking vessel
Implementation Method 3
heat from the flame may not be efficiently transferred to the cooking vessel and may be lost to the surrounding environment

AI summary
Portable cooking assemblies are disclosed herein. The portable cooking assemblies include a windscreen and a cooking vessel assembly. The windscreen includes a body that may be movable between a ready-to-use configuration in which the body defines an inner volume configured to receive the cooking vessel assembly and a compact storage configuration. The windscreen may be configured to fit inside the cooking vessel assembly in the compact storage configuration. The windscreen may include a releasable fastening mechanism that is configured to selectively hold the windscreen in the ready-to-use configuration. The windscreen is configured to hold the cooking vessel assembly above a flame, serving as a base for the cooking vessel assembly. Specifically, the windscreen may include one or more support members that extend radially inwardly from the body when the windscreen is in the ready-to-use configuration, and that are configured to hold and/or center the cooking vessel assembly.
