Solution Overview

Problem

Current cooking appliances with a single venting passage struggle to accommodate both baking and conventional cooking modes, as they require different venting needs, making it difficult to achieve compatible venting modes for efficient cooking.

Innovation Solution

A cooking appliance design featuring a venting passage on the appliance cover, a baking assembly, and a detachable venting cap that switches positions to manage air flow, allowing for simultaneous air admission and venting during baking and rapid air venting during conventional cooking, ensuring improved efficiency and stability in both modes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single venting passage is used in the cooking appliance, then the device complexity is reduced, but the adaptability to different cooking modes (baking and conventional cooking) deteriorates

Engineering Contradiction:
Improveventing passage structureVSAvoidventing mode compatibility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The venting cap is designed to be movable between two positions: a first position where it blocks the venting passage for conventional cooking, and a second position where it allows venting for baking mode. This dynamic repositioning enables a single venting passage to accommodate different cooking mode requirements without increasing device complexity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The single venting passage is designed to serve multiple functions by combining it with a movable venting cap. The same passage can be used for both blocking (conventional cooking) and venting (baking mode), making the venting system universal for different cooking modes rather than requiring separate passages for each mode

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

2Object-affected harmful factors

If the venting cap blocks the venting passage during conventional cooking, then the humidity accumulation is reduced, but the air circulation required for baking is restricted

Engineering Contradiction:
Improvehumidity accumulationVSAvoidair circulation
Core Design Contradiction:
Object-affected harmful factorsVSProductivity

Solution Approach 1:

The venting cap is dynamically positioned to block the venting passage during conventional cooking, preventing humid air from entering and accumulating inside the appliance body. During baking mode, the cap is repositioned to allow air circulation. This dynamic blocking/allowing mechanism resolves the contradiction between preventing humidity accumulation and enabling air circulation

Inventive Principle:
Principle #15Dynamics

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 design enhances baking efficiency by prolonging air circulation and ensures stable conventional cooking by effectively managing air flow, reducing the risk of humidity and oily waste accumulation, thereby improving user experience and appliance safety.

AI summary

A cooking appliance comprises an appliance cover (1), an appliance body (2) and an inner lid (3), the appliance cover (1) being coveringly arranged above the appliance body (2) in a closable and openable manner; the appliance body (2) being provided with a heating structure. The appliance cover (1) comprises a cover body (4), a baking assembly (5) and a venting cap (7), the cover body (4) being provided with a venting passage (6) through which the inside of the cooking appliance communicates with the outside, the inner lid (3) being detachably mounted to the cover body (4); the baking assembly (5) being arranged below the cover body (4), the inner lid (3) being located below the baking assembly (5) when mounted to the cover body (4); the venting cap (7) being detachably mounted at any one end of the two ends of the venting passage (6), wherein the venting cap (7) is assembled at a bottom end of the venting passage (6) when the inner lid (3) is dismounted, and the venting cap (7) is assembled at a top end of the venting passage (6) after the inner lid (3) is mounted. The cooking appliance can solve the problem that two venting modes are incompatible.
