Innovation Solution

A cold smoker with an electronic heating element and temperature control system that uses ceramic infrared heaters to maintain precise temperatures for infusing food with natural wood chips, herbs, or spices, ensuring optimal flavor extraction without open flames.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If open flame is used for smoking, then ignition is achieved, but temperature control is lost and toxins are extracted

Engineering Contradiction:
Improveignition capabilityVSAvoidtemperature control
Core Design Contradiction:
Ease of manufactureVSTemperature

Solution Approach 1:

The patent replaces the mechanical/open flame ignition system with an electronic heating element system. The electronic heater provides controlled thermal energy without open flame, enabling precise temperature regulation through electronic control circuits while eliminating the temperature runaway problem associated with open flames.

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

Solution Approach 2:

The patent changes the temperature parameter control from uncontrolled (open flame) to precisely controlled (electronic heating with thermostat). The system maintains temperature within a specific range (16-32°C for cold smoking) by using temperature sensors and control circuits that adjust heating power dynamically.

Inventive Principle:
Principle #35Parameter changes

2Ease of manufacture

If high temperature is used for smoking, then ignition is achieved, but unpleasant odors and toxins are extracted

Engineering Contradiction:
Improveignition capabilityVSAvoidtoxin extraction
Core Design Contradiction:
Ease of manufactureVSObject-generated harmful factors

Solution Approach 1:

The patent changes the temperature parameter from high temperature (open flame ~1,649°C) to controlled low temperature (16-32°C for cold smoking). This parameter change prevents the thermal decomposition of wood chips that produces toxins and unpleasant odors, while still achieving effective smoke extraction through controlled heating.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent replaces the high-temperature combustion process with a low-temperature controlled heating process. The electronic heating element delivers thermal energy without reaching combustion temperatures, eliminating the formation of harmful combustion byproducts while maintaining smoke generation capability.

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

3Productivity

If traditional smoke gun is used, then smoke generation is achieved, but consistent flavor extraction is not achieved

Engineering Contradiction:
Improvesmoke generationVSAvoidflavor extraction consistency
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent incorporates temperature sensors and control circuits that continuously monitor and adjust heating power to maintain consistent temperature. This feedback mechanism ensures repeatable flavor extraction by keeping the heating process within optimal temperature ranges, eliminating the variability inherent in manual open flame methods.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent establishes precise temperature parameters for different wood chip types and smoking conditions. By controlling temperature within specific ranges rather than using uncontrolled open flame, the system achieves consistent flavor extraction and smoke generation across multiple operations.

Inventive Principle:
Principle #35Parameter changes
