Solution Overview

Problem

Conventional electric cooking devices with multiple inner pots are integral and occupy more space, making them inconvenient for use and storage due to their fixed structure.

Innovation Solution

An electric cooking device comprising multiple detachable electric cookers that can be connected and used independently, allowing for flexible combination and disconnection to optimize space utilization and ease of use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple inner pots are placed in a single integral outer pot, then the cooking device can cook multiple ingredients simultaneously, but the device occupies larger space and is inconvenient for use

Engineering Contradiction:

Improvesimultaneous cooking capabilityVSAvoidspace occupation

Core Design Contradiction:

ProductivityVSVolume of moving object

Solution Approach 1:

The cooking device is divided into multiple independent electric cookers, each with its own heating element and control. These modular cookers can be separated and stored individually, reducing space occupation when not in use, while still enabling simultaneous cooking of multiple ingredients when assembled together.

Inventive Principle:

Principle #1Segmentation

2Productivity

If multiple inner pots are placed in a single integral outer pot, then the cooking device can cook multiple ingredients simultaneously, but the device is inconvenient for use due to fixed structure

Engineering Contradiction:

Improvesimultaneous cooking capabilityVSAvoidconvenience of use

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The electric cookers are designed with detachable connections, allowing the structure to change from fixed to flexible. Users can assemble and disassemble the cookers based on their cooking needs, making the device more adaptable and easier to operate for different cooking scenarios.

Inventive Principle:

Principle #15Dynamics

3Volume of moving object

If electric cookers are detachably connected, then the device can be freely combined and improves space utilization, but the connection structure becomes more complex

Engineering Contradiction:

Improvespace utilizationVSAvoidconnection structure

Core Design Contradiction:

Volume of moving objectVSDevice complexity

Solution Approach 1:

The connection structure is segmented into standardized interfaces between adjacent electric cookers. Each interface uses simple coupling mechanisms that enable easy assembly and disassembly, reducing the overall complexity despite the modular design.

Inventive Principle:

Principle #1Segmentation
