Solution Overview

Problem

Existing electric cooking appliances with drainage systems are difficult to position for efficient draining operations, lack stability during draining, and are not economically efficient in their design.

Innovation Solution

A cooking assembly comprising an electric cooking appliance with a vat equipped with a drainage system and a draining receptacle, where the receptacle has upper supports from its side wall to stabilize the appliance during draining, and a control element to open the valve, allowing the appliance to rest on separate support zones to prevent contact with the receptacle, thus enhancing stability and reducing dimensions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the draining receptacle uses a simple annular support area formed by a projection from the internal side wall, then the construction is simple, but the positioning of the vat is not easy and stability is poor

Engineering Contradiction:
Improveconstruction simplicityVSAvoidpositioning ease
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The support area is segmented into multiple discrete support points (first support point, second support point, third support point, fourth support point) arranged at specific locations on the annular support area, rather than a continuous projection. This segmentation provides defined positioning references for the vat while maintaining construction simplicity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the annular support area have different functions: the support points provide localized contact for positioning, while the overall annular structure provides stability. The support points are positioned at specific locations (e.g., opposite each other, at 45-degree angles) to optimize both positioning ease and stability.

Inventive Principle:
Principle #3Local quality

2Ease of manufacture

If the annular support area is formed by a projection from the internal side wall, then the construction is simple, but the stability of the appliance during draining is insufficient

Engineering Contradiction:
Improveconstruction simplicityVSAvoidappliance stability
Core Design Contradiction:
Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The support points are asymmetrically arranged within the annular support area, with specific geometric relationships (opposite pairs, 45-degree angle arrangements) that provide optimal stability during the draining operation while maintaining a simple annular overall structure.

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The support system transitions from a simple radial projection to a three-dimensional arrangement where support points are positioned at specific heights and angular positions, creating a stable platform that prevents appliance movement during draining.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Volume of stationary object

If the draining receptacle dimensions are reduced, then the assembly size is limited, but the rigidity of the side wall holding the appliance may be compromised

Engineering Contradiction:
Improvereceptacle dimensionsVSAvoidside wall rigidity
Core Design Contradiction:
Volume of stationary objectVSStrength

Solution Approach 1:

The side wall is segmented into multiple reinforcement elements (first, second, third, fourth reinforcement elements) positioned at specific locations, providing localized rigidity without requiring overall wall thickness increases, thus maintaining compact dimensions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The side wall incorporates reinforcement elements that may be made of different materials or structures (such as ribs, stiffeners, or composite layers) to enhance rigidity in specific regions while keeping the overall receptacle dimensions small.

Inventive Principle:
Principle #40Composite materials
