Problem
Traditional barbecue grills are inefficient in terms of energy use and require manual monitoring, leading to suboptimal cooking and environmental impact due to low charcoal combustion efficiency and the need for constant food turning.
Innovation Solution
A fully automatic barbecue grill featuring a smokeless heating pipe, gas control device for efficient fuel gas combustion, and an automatic grill device that rotates food periodically, utilizing a speed-controlled fan for optimized air-fuel mixture and a synchronous motor for automated food rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If charcoal is used for grilling, then the grill can be operated traditionally, but combustion efficiency is low and carbon emission is high
Solution Approach 1:
The patent replaces the traditional charcoal combustion system with a gas burner system that uses propane or natural gas. This substitution eliminates incomplete combustion issues associated with charcoal, achieving complete combustion with higher efficiency and no carbon emission, directly resolving the technical contradiction between energy efficiency and harmful emissions.
Solution Approach 2:
The patent changes the fuel parameter from solid charcoal to gaseous fuel (propane/natural gas), which fundamentally alters the combustion characteristics. The gaseous fuel provides consistent combustion efficiency and eliminates carbon emission, resolving the contradiction by changing the physical state and chemical composition of the fuel.
2Ease of operation
If manual monitoring is used for grilling, then the grill can be operated simply, but someone must always watch and turn the food
Solution Approach 1:
The patent incorporates an automatic food turning mechanism that rotates the food periodically without human intervention. The system serves itself by automatically monitoring and adjusting the grilling process, eliminating the need for constant manual attention while maintaining even cooking, thus resolving the contradiction between operational simplicity and automation.
Solution Approach 2:
The patent implements periodic automatic turning of the food using a motor-driven mechanism. The food is rotated at regular intervals to ensure even heat distribution, replacing continuous manual monitoring with periodic automated action, thereby resolving the contradiction between ease of operation and extent of automation.
3Device complexity
If traditional grilling is used, then the setup is simple, but the grill produces soot and unhealthy emissions
Solution Approach 1:
The patent replaces the charcoal-based heating system with a gas burner system connected to a smokeless heating pipe. This substitution eliminates soot production entirely while maintaining relatively simple device structure, resolving the contradiction between device complexity and harmful emissions through a cleaner combustion technology.
Solution Approach 2:
The patent introduces a smokeless heating pipe as an intermediary component between the gas burner and the food. This intermediary channel directs the heated air efficiently while preventing soot and unhealthy emissions from contacting the food, resolving the contradiction by adding a functional element that eliminates harmful factors without significantly increasing complexity.
4Loss of energy
If gas burner is used instead of charcoal, then energy efficiency improves, but the device complexity increases
Solution Approach 1:
The patent replaces the simple charcoal ignition system with a gas burner system that includes a mixing chamber, Venturi tube, and elongated chamber with multiple holes. While this improves energy efficiency through complete combustion, it inherently increases device complexity due to the additional components needed for gas mixing and distribution.
Solution Approach 2:
The patent designs the gas burner system to serve multiple functions: the mixing chamber creates the fuel-air mixture, the Venturi tube provides automatic gas flow control through pressure differential, and the elongated chamber with holes distributes the mixture uniformly. This multi-functionality reduces the need for separate control mechanisms, partially mitigating the complexity increase while maintaining high energy efficiency.
