Grill Smoke Assembly with Controlled Combustion for Electric Cooking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric cooking appliances struggle to impart significant smoke flavor into food due to limited control over smoke output, and existing grilling systems face challenges in managing smoke generation and distribution.
Innovation Solution
A cooking device with a smoke assembly that includes a fuel box, igniter, fan, and temperature sensor, allowing for controlled smoke generation and circulation within a cooking chamber, along with a baffle system to manage airflow and ensure consistent smoke distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a smoke assembly is added to a cooking device to improve smoke flavor, then smoke flavor is enhanced, but device complexity increases
Solution Approach 1:
The smoke assembly is integrated within the cooking device housing, with the fuel box nested inside the cooking chamber. The baffle is positioned within the cooking chamber to redirect smoke flow. This nesting approach allows the smoke generation system to be incorporated without significantly increasing the overall device footprint or complexity.
Solution Approach 2:
The fan serves multiple functions: it circulates air during cooking operations and draws smoke into the cooking chamber during smoking operations. The baffle serves dual purposes of directing smoke flow and potentially serving as a structural support element. This multi-functionality reduces the need for additional dedicated components.
2Quantity of substance
If smoke generation is increased to improve smoke flavor, then smoke output is enhanced, but control over smoke output becomes difficult
Solution Approach 1:
The system incorporates a temperature sensor that monitors the internal temperature of the fuel box and provides feedback to the controller. The controller adjusts the power to the heating element and the operation of the fan based on this temperature feedback, maintaining optimal combustion conditions for consistent smoke generation. This closed-loop control enables precise regulation of smoke output.
Solution Approach 2:
The fan speed is variable and can be adjusted dynamically based on cooking requirements. The heating element power can also be modulated to control the rate of fuel combustion. These dynamic adjustments allow the system to optimize smoke generation in real-time, providing precise control over smoke output rather than fixed, unadjustable smoke production.
3Ease of operation
If electric heating elements are used to simplify the cooking device, then ease of operation is improved, but smoke flavor capability is limited
Solution Approach 1:
The system merges electric heating technology with traditional smoke generation by using an electric heating element to ignite and sustain combustion of solid fuel (wood chips or pellets). This combination allows the device to maintain the simplicity and ease of operation of electric appliances while achieving authentic smoke flavor through controlled combustion of natural fuel materials.
Solution Approach 2:
The electric heating element serves as an intermediary that bridges between the ease of electric operation and the smoke generation capability. Instead of directly burning fuel to produce smoke, the electric heater first ignites the fuel and maintains combustion at controlled temperatures, mediating between electrical control and thermal smoke production processes.
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 system effectively imparts smoke flavor into food by generating and circulating smoke through the cooking chamber, providing precise control over smoke volume and duration, enhancing the cooking experience.
Implementation Method 1
a fan can be disposed in the housing and configured to circulate air in the hollow cooking chamber
Implementation Method 2
At least one heating element can be disposed in the housing that is in thermal communication with the hollow cooking chamber
Implementation Method 3
the baffle can be in fluid communication with the hollow cooking chamber and the interior chamber, and the baffle can be configured to allow smoke to be drawn therethrough from the interior chamber into the hollow cooking chamber
