Outdoor Grill Smoke Control Using Pellet Feed and Temperature Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional outdoor grills and smokers lack advanced control features, limiting users' ability to customize cooking and smoking processes based on flavor, temperature, and smoke levels, forcing them to rely on basic manual or electronic controls that do not adapt to changing conditions.
Innovation Solution
An electronically-controlled outdoor grill system that allows remote operation and automatic adjustment of components such as combustible pellet addition, fan operation, and temperature control, based on predefined cooking profiles and smoke generation patterns, enabling precise control over the cooking process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional manual or electronic controls are used in outdoor grills and smokers, then the device complexity is reduced and ease of operation is improved, but the adaptability and control precision over cooking parameters (temperature, smoke levels, flavor) are limited
Solution Approach 1:
The control system dynamically adjusts cooking parameters (temperature, smoke generation, fan operation) in real-time based on sensor feedback and user-defined profiles, transforming static manual controls into adaptive automated systems that respond to changing cooking conditions
Solution Approach 2:
The system enables precise control and customization of multiple cooking parameters including temperature, smoke levels, and flavor profiles through electronic controls that can be remotely adjusted, allowing users to modify cooking conditions without physical intervention
2Manufacturing precision
If basic electronic controls are used for temperature regulation, then the ease of operation is improved, but the manufacturing precision and control precision over cooking parameters are insufficient
Solution Approach 1:
The system incorporates sensors that continuously monitor temperature and other cooking parameters, providing feedback to the electronic controller which automatically adjusts heating elements and smoke generation to maintain precise control over cooking conditions
Solution Approach 2:
A remote communication interface acts as an intermediary, allowing users to control the grill/smoker from distant locations through wireless connectivity, eliminating the need for physical presence at the device while maintaining precise control
3Extent of automation
If conventional controls are used, then the device complexity is minimized, but the extent of automation and ability to respond to changing conditions is limited
Solution Approach 1:
The system performs self-adjustment of cooking parameters based on sensor feedback and pre-programmed profiles, automatically regulating temperature, smoke generation, and fan operation without requiring continuous user intervention or complex manual adjustments

Function Achieved in This Case
Enables users to cook food with precise control over temperature, smoke levels, and flavor, maintaining consistent results regardless of external conditions, allowing for customized cooking cycles and profiles to be implemented remotely.
Implementation Method 1
adds a specified amount of combustible pellets to a combustion area within the outdoor grill, such that the combustible pellets begin to burn

AI summary
Embodiments are directed to smoking food in an outdoor grill using a customized smoking routine. In one scenario, an electronic controller of an outdoor grill receives an input to initiate smoke generation according to a specified smoke generation pattern, including: adding a specified amount of combustible pellets to a combustion area within the outdoor grill, such that the combustible pellets begin to burn, measuring a current internal temperature of the outdoor grill and, if below a threshold value, adding a specified amount of additional combustible pellets to the combustion area sufficient to raise the temperature to another threshold value, allowing the internal temperature to cool a temperature below the first threshold value and, upon determining that the temperature of the outdoor grill has cooled below the first specified threshold value, adding additional combustible pellets to the combustion area sufficient to raise the temperature to at least the second threshold value.
