Solution Overview

Problem

Achieving optimal smoking conditions for food is challenging due to the long duration of smoking processes and the inability to monitor internal conditions effectively in traditional smokers, leading to inconsistent results.

Innovation Solution

An adjustable barbecue smoker device with a hyperboloid-shaped container body, air flow control mechanisms, sensors, and a control device that adjusts airflow based on collected data to maintain optimal cooking conditions, allowing for remote control via a mobile app.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional smokers are used for long-duration smoking, then food can be cooked and flavored, but internal conditions cannot be monitored effectively leading to inconsistent results

Engineering Contradiction:
Improvemonitoring of internal conditionsVSAvoidconsistency of smoking results
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The patent implements sensors that continuously monitor temperature and humidity inside the smoker, with data transmitted to a mobile device. The system provides real-time feedback on internal conditions, allowing users to adjust settings to maintain optimal smoking parameters throughout the long cooking duration, thereby ensuring consistent results.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces manual monitoring and adjustment of smoking conditions with automated electronic sensors and digital control systems. Temperature and humidity are measured electronically and transmitted via wireless communication, eliminating the need for physical inspection and manual regulation, thus improving measurement precision and reliability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Loss of information

If the smoker is opened to monitor food during smoking, then food can be checked, but the smoking process is substantially interfered with

Engineering Contradiction:
Improveability to see the foodVSAvoidsmoking conditions stability
Core Design Contradiction:
Loss of informationVSTemperature

Solution Approach 1:

The patent replaces visual inspection requiring opening the smoker with electronic imaging or sensing systems that can detect food status through the closed chamber. Sensors monitor temperature, humidity, and food progression without physical access, eliminating temperature fluctuations caused by opening the smoker while still providing information about the cooking process.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces sensors and wireless communication as intermediaries between the user and the food. Instead of directly observing food by opening the smoker, users receive data transmissions about internal conditions and food status, allowing monitoring without physical intervention that would disrupt the smoking environment.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If manual monitoring and adjusting is performed during smoking, then conditions can be checked, but constant attention is required increasing time loss

Engineering Contradiction:
Improvecontrol of cooking conditionsVSAvoidtime for monitoring and adjusting
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent implements an automated system where sensors continuously monitor temperature and humidity, and the mobile device application automatically tracks cooking progress and provides guidance. The system serves itself by maintaining optimal conditions through automated feedback loops, eliminating the need for constant human attention and reducing time loss while ensuring reliable control.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent establishes continuous feedback loops where sensors monitor conditions and transmit data to the user's mobile device in real-time. The system automatically adjusts or alerts users about necessary adjustments, providing ongoing control without requiring constant manual intervention, thus reducing time loss while maintaining reliability.

Inventive Principle:
Principle #23Feedback

4Ease of operation

If fixed smoking time is used, then cooking process is simple, but optimal results cannot be achieved due to changing conditions

Engineering Contradiction:
Improvesimplicity of cooking processVSAvoidquality of smoking results
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent transforms fixed, static cooking times into dynamic, adaptive cooking profiles. The system uses sensor data to monitor actual cooking conditions and automatically adjusts timing and temperature parameters in real-time, allowing the cooking process to adapt to changing internal conditions while maintaining simple user interaction through the mobile application.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements variable cooking parameters that change based on monitored conditions. Instead of fixed time and temperature settings, the system continuously adjusts parameters such as temperature, humidity, and cooking duration based on real-time sensor feedback, ensuring optimal results while maintaining ease of operation through automated control.

Inventive Principle:
Principle #35Parameter changes
