Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable heating devices for warming enclosed areas, such as under a blanket or within a sleeping bag, pose safety risks due to the potential for carbon monoxide poisoning and are often unable to operate without a power source, making them unsuitable for camping or 'off-grid' environments.
Innovation Solution
A rechargeable, portable heating device with a retractable hose and a heating module powered by a battery unit, featuring an air intake, heating element, and temperature control via remote device signals, ensuring safe and efficient heating without the risk of combustion or carbon monoxide poisoning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If existing portable heating devices are used in enclosed areas, then heating effect is achieved, but carbon monoxide poisoning risk increases
Solution Approach 1:
The patent replaces combustion-based heating (chemical/mechanical system) with electric heating (electrical system). The heating element uses electrical resistance to generate heat, eliminating the need for fuel combustion and thereby removing the source of carbon monoxide production while maintaining effective heating in enclosed spaces
Solution Approach 2:
The patent introduces an electric heating element as an intermediary between the power source and the air to be heated. This intermediary converts electrical energy directly to thermal energy without involving combustion processes, thus providing heat without generating harmful carbon monoxide gases
2Ease of operation
If existing portable heating devices are used without power source, then portability is improved, but operation capability deteriorates
Solution Approach 1:
The heating device is designed with dual power source capability, allowing it to operate both with external power sources (wall outlets, car chargers) and with an integrated rechargeable battery. This multi-functionality ensures the device can be used in various environments including camping and off-grid locations where traditional power sources are unavailable
Solution Approach 2:
The device includes a rechargeable battery that can be charged in advance when power is available. This preliminary charging action stores energy for later use in locations without power sources, enabling portable operation without compromising heating capability when needed
3Productivity
If heating device operates in enclosed space, then heating efficiency is improved, but safety risk increases
Solution Approach 1:
The patent replaces combustion-based heating with electric heating, substituting a chemical process with an electrical one. This substitution maintains high heating efficiency in enclosed spaces while eliminating the production of carbon monoxide and other combustion byproducts, thereby resolving the safety risk associated with enclosed space heating
