Integrated Portable Gas Heater for Assembly-Free Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable gas heaters require assembly, making them inconvenient for immediate use, especially in outdoor or indoor settings where quick access to heat is needed.
Innovation Solution
A self-contained portable gas heater design featuring an infrared burner with a pilot flame arrangement, safety valve, and secure gas bottle positioning system, allowing for immediate use without assembly, with a compact and lightweight structure facilitated by a stainless steel or semi-soft connecting tube and a resilient bottle positioning mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the gas heater is designed as a self-contained integral unit, then the ease of operation is improved (immediate use without assembly), but the device complexity increases (integrally formed body with multiple components)
Solution Approach 1:
The patent combines multiple functional components (heater body, gas burner, safety valve, control button, connecting tube, and gas bottle positioning arrangement) into a single integrally formed body that requires no assembly. This merging of components directly resolves the technical contradiction by enabling immediate use without assembly while incorporating all necessary functional elements within the unified structure.
2Productivity
If the gas heater is designed as a self-contained integral unit, then the productivity is improved (immediate availability for use), but the loss of time is worsened (manufacturing and integration time)
Solution Approach 1:
The gas heater is manufactured as a complete integral unit with all components pre-assembled and integrated during production. This preliminary action of assembling all components before delivery eliminates any assembly time required by the end user, thereby improving productivity and immediate availability while the manufacturing time is absorbed into the production process rather than affecting user readiness.
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
Enables immediate and convenient use of the gas heater for both indoor and outdoor applications, eliminating the need for assembly and ensuring zero waiting time, while maintaining compactness and portability.
Implementation Method 1
The characteristic of this type of portable gas heater is that: the gas burner is an infrared burner which has two inner cavities.
Implementation Method 2
a gas burner, a gas supply arrangement arranged for connecting to a gas bottle which contains a gas supply
Implementation Method 3
the safety device comprises a thermocouple, a pilot flame unit, and an electrode rod
Implementation Method 4
a bottle positioning base mounted onto the bottom panel of the heater body which comprises two positioning tubes and a resilient element on each of the positioning tubes

AI summary
A portable gas heater includes a heater body, a gas burner mounted on a front panel of the heater body, a gas supply arrangement connected between the gas burner inside the heater body and the gas bottle for providing a gas passage including a safety valve, a control button and a connecting tube, a gas bottle positioning arrangement, and a pilot flame arrangement mounted on the heater body near the gas burner and connected to the safety valve through a gas inlet. The pilot flame arrangement includes a thermocouple, a pilot flame unit, and an electrode rod connected to an ignition wire of the safety valve. The pilot flame unit includes a pilot fire nozzle, a mixing tube and a connector connected with each others. The heater is compact, small and light-weighted while ready for immediate use without assembly and disassembly requirements, thereby convenience for indoor and outdoor use.
