Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the heating member is made finer to reduce device size and improve portability, then the device becomes more compact and easier to carry, but the structural strength of the heating member deteriorates, leading to poor attachment with the liquid conducting material

Engineering Contradiction:
Improvedevice sizeVSAvoidstructural strength of heating member
Core Design Contradiction:
Volume of moving objectVSStrength

Solution Approach 1:

The heating member is divided into multiple heating sections, each independently supported by support members. This segmentation allows each section to be finer for compactness while the support members provide collective structural strength. The heating sections are arranged in an array with each section having independent liquid conducting members, enabling the device to maintain small size while ensuring adequate structural support through the distributed support member network.

Inventive Principle:
Principle #1Segmentation

2Volume of moving object

If the heating member is made finer to reduce device size, then the device becomes more portable, but the attachment between heating member and liquid conducting material becomes poor, causing dry burning

Engineering Contradiction:
Improvedevice sizeVSAvoidattachment reliability
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

Support members are introduced as intermediary elements between the heating sections and the liquid conducting member. These support members extend from the substrate toward the heating section and provide mechanical support that ensures reliable attachment. The support members act as mediators that transfer and distribute mechanical stress, preventing the heating member from detaching due to its fine structure, thereby eliminating dry burning while maintaining compact device dimensions.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Volume of moving object

If the heating member is made finer to improve portability, then the device is easier to carry, but harmful substances such as aldehydes are produced due to dry burning

Engineering Contradiction:
Improvedevice sizeVSAvoidharmful substances production
Core Design Contradiction:
Volume of moving objectVSObject-generated harmful factors

Solution Approach 1:

The support members are designed to preemptively prevent detachment of the heating member before dry burning can occur. By providing continuous mechanical support from the substrate to the heating section, the structure eliminates the risk of heating member displacement that would lead to dry burning and harmful substance generation. This preliminary protective structure ensures that the heating member remains properly attached throughout operation, preventing the formation of harmful substances while maintaining the compact fine-structured design.

Inventive Principle:
Principle #9Preliminary anti-action
