Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the flexible heating device uses a single heating function, then the device structure remains simple, but the device cannot meet diverse user needs in various scenarios

Engineering Contradiction:

Improvefunctional versatilityVSAvoiddevice structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The heating device is segmented into distinct functional zones: a first heating area with first heating wires for heat preservation, and a second heating area with second heating wires for cooking. The silicone pad is also segmented into a first appliance area and a second appliance area. This segmentation allows each zone to serve specific functions independently, enhancing versatility while maintaining clear structural organization.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The silicone pad serves multiple functions: it acts as an insulating layer, a structural support, a mounting surface for heating wires and appliance bases, and defines functional areas through its molded凸起 structures. The single device can perform both heat preservation and cooking operations, making it a multi-functional universal heating solution.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If heat preservation and cooking functions are integrated in the same area, then the device structure remains simple, but the heating functions interfere with each other

Engineering Contradiction:

Improvefunctional integrationVSAvoidheating function interference

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The heating functions are spatially segmented into distinct areas: the first heating wires are located in the first heating area for heat preservation, while the second heating wires are located in the second heating area for cooking. The凸起 structures physically separate these functional zones, preventing thermal interference between the two heating functions while allowing both to operate simultaneously or independently.

Inventive Principle:

Principle #1Segmentation

3Ease of manufacture

If the silicone pad structure is simplified without凸起, then the manufacturing process becomes simpler, but the heating wires and appliance bases cannot be securely fixed

Engineering Contradiction:

Improvemolding processVSAvoidfixing reliability

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The凸起 structures are integrally molded with the silicone pad in a single manufacturing process, merging the fixation elements with the main body. This eliminates the need for separate mounting steps, simplifying manufacturing while providing reliable mechanical anchoring for the heating wires and appliance bases through the molded凸起 features.

Inventive Principle:

Principle #5Merging (Combining)
