Solution Overview

Problem

Conventional grills lack a smoking function, limiting their ability to produce a smoked effect in food, which is a desired culinary outcome.

Innovation Solution

A grill design incorporating a removable smoker unit with an electric heating element and a socket unit that allows for the heating of wood chips or charcoal to produce smoke, integrating with the existing grilling mechanism to create a closed cooking space for smoking food.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional grill is used, then the grilling function is provided, but the smoking function is missing

Engineering Contradiction:
Improvecooking functionVSAvoidstructure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The grill is designed to perform multiple cooking functions by integrating both a grilling system and a smoking system. The grill body can accommodate either a pan for grilling or a smoker box for smoking, allowing the same device to provide both grilling and smoking functions without requiring separate appliances.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The grill is divided into functionally independent modules: a grilling module (pan, grill rack) and a smoking module (smoker box, electric heating unit). These modules can be independently installed or removed, allowing users to switch between grilling and smoking functions by simply replacing the pan with the smoker box assembly.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If a smoker unit is integrated into the grill, then the smoking function is added, but the device complexity increases

Engineering Contradiction:
Improvecooking functionVSAvoidstructure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The smoker box is designed with movable components, including a removable lid and an electric heating unit that can be inserted or removed from the smoker box. This dynamic design allows for easy assembly and disassembly, simplifying the integration process and reducing the perceived complexity despite adding functionality.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The electric heating unit is nested within the smoker box structure, with the heating element positioned inside the smoker box and connected via terminals that interface with the grill body. This nested arrangement consolidates components into a compact unit, minimizing the increase in overall device complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Ease of operation

If the smoker box is made removable, then the ease of operation is improved, but the reliability of connection may deteriorate

Engineering Contradiction:
ImproveinstallationVSAvoidconnection
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

A connection structure with terminal pins and corresponding terminal holes serves as an intermediary between the smoker box and the grill body. This intermediary mechanism ensures reliable electrical and mechanical connection when the smoker box is installed, while still allowing for easy removal when needed.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The connection between the smoker box and grill body is achieved through a simple terminal pin insertion system rather than complex mechanical fastening. The terminal pins insert into terminal holes to establish both mechanical support and electrical connection, simplifying the installation process while maintaining connection reliability.

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

AI summary

A grill with a removable smoker unit comprises a pan, a body, a pan cover, a smoker unit and a socket unit, wherein the smoker unit comprises a smoker box and a heating tube member with two plug terminals. The smoker unit is removably mounted on one side of the body, wherein there is a hole in the pan where the smoker unit inserts into the body, and a removable insulation lid mounted on the hole. The socket unit is mounted in the body, and provides electrical connection. The socket unit has holes for receiving the plug terminals. The grill with these structures not only has the conventional functions, but also provides an optional smoking function.
