Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a steam generator is designed with fixed shape and output, then manufacturing and standardization are simplified, but it cannot provide optimal performance for cavities of various volumes

Engineering Contradiction:
Improveadaptability to various cavity volumesVSAvoidcomplexity of individual development for each cavity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The steam generator is divided into multiple detachable modules, each capable of independently generating steam. These modules can be assembled in different quantities and configurations to match various cavity volumes, eliminating the need for individual development for each application.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The steam generator transitions from a fixed configuration to a dynamic, adjustable system where modules can be added or removed based on the cavity volume requirements, enabling optimal performance across different applications.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If individual steam generators are developed for each cavity volume, then optimal performance is achieved, but manufacturing cost increases and productivity decreases

Engineering Contradiction:
Improveperformance optimization for each cavityVSAvoidmanufacturing productivity
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

By segmenting the steam generator into standardized modules, a single module design can be mass-produced and then assembled in different quantities to meet various cavity volume requirements, significantly improving manufacturing productivity while maintaining performance optimization.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The standardized modules are designed to be universal and interchangeable, allowing the same module to be used across different applications and cavity volumes, thereby reducing manufacturing costs and increasing productivity through economies of scale.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If modules are assembled to vary internal volume and output, then adaptability is improved, but steam leakage may occur at coupling points

Engineering Contradiction:
Improveadjustable internal volume and outputVSAvoidsteam leakage prevention
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

A coupling member is introduced as an intermediary component between modules to ensure reliable connection. The coupling member includes a coupling protrusion that fits into a coupling groove, creating a sealed connection that prevents steam leakage while allowing modular assembly.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Adaptability or versatility

If the heater output is varied by using different heater specifications, then performance is optimized, but new standards must be acquired according to laws and regulations

Engineering Contradiction:
Improveheater output variationVSAvoidcompliance with standards and regulations
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

Instead of using different heater specifications that would require new standards, the system achieves variable output by changing the number of identical heater modules assembled. Each module uses the same standardized heater, maintaining compliance with existing standards while providing flexible output adjustment.
