Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If welding or riveting methods are used to connect the electrode and heating material, then electrical connection is achieved, but the assembly becomes difficult to manufacture and the connection is prone to disconnection for fine heating materials

Engineering Contradiction:
Improveconnection reliabilityVSAvoidassembly difficulty
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent introduces a liquid conducting member as an intermediary component between the electrode and heating material. This mediator absorbs the heating material through capillary action and provides a flexible conductive path, eliminating the need for direct rigid connections like welding or riveting. The liquid conducting member accommodates the fine dimensions of the heating material while ensuring reliable electrical and thermal contact.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the physical state of the connection from rigid (welding/riveting) to flexible by using a liquid conducting member that can deform and adapt to the fine heating material. The liquid conducting member's ability to change shape and conform to the heating material's dimensions enables reliable connection without the complexity of precision welding or riveting processes.

Inventive Principle:

2Speed

If the heating member is made extremely fine to achieve fast heating and cooling, then thermal response speed improves, but the connection and assembly process becomes significantly more difficult

Engineering Contradiction:
Improvethermal response speedVSAvoidassembly difficulty
Core Design Contradiction:
SpeedVSEase of manufacture

Solution Approach 1:

The patent employs a flexible liquid conducting member that can accommodate extremely fine heating materials. This flexible intermediary allows the heating member to be made as thin as needed for fast thermal response while the liquid conducting member's flexibility ensures it can still make reliable contact without requiring complex assembly processes for such delicate components.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The liquid conducting member serves as a mediator that bridges the gap between the macro-scale electrode and the micro-scale heating material. This intermediary enables the use of extremely fine heating materials for fast thermal response while simplifying the assembly process, as the liquid conducting member can be positioned and secured more easily than direct welding or riveting of fine wires.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If traditional welding or pressing methods are used for fine heating materials, then connection is achieved, but mass production becomes difficult due to breaking and pressing difficulties

Engineering Contradiction:
Improveconnection reliabilityVSAvoidmass production capability
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The liquid conducting member acts as a mediator that protects the fine heating material from the mechanical stresses of welding and pressing operations. By providing a softer, more compliant interface, it allows the heating material to be connected without direct high-force mechanical operations, enabling more reliable mass production of devices with fine heating elements.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the mechanical properties of the connection interface by using a liquid conducting member that is softer and more compliant than traditional rigid connectors. This parameter change allows for more forgiving assembly processes that are better suited for mass production, reducing the occurrence of breaking and pressing difficulties associated with fine heating materials.
