Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a fire extinguishing molded product is used, then fire extinguishing function is provided, but manufacturing process is not established for productivity and mass production

Engineering Contradiction:
Improvemanufacturing productivityVSAvoidmanufacturing process complexity
Core Design Contradiction:
ProductivityVSEase of manufacture

Solution Approach 1:

The invention changes the physical form parameter of the fire extinguishing agent from molded products to sheet form. This parameter change enables the use of conventional sheet manufacturing processes (coating, laminating, printing) that are suitable for mass production, thereby resolving the contradiction between providing fire extinguishing function and achieving manufacturing productivity.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The invention extracts the fire extinguishing agent from its traditional molded product form and applies it as a coating or laminate on substrates. This extraction allows the fire extinguishing function to be integrated into existing sheet production processes, enabling mass production while maintaining effectiveness.

Inventive Principle:
Principle #2Taking out (Extraction)

2Productivity

If fire extinguishing agent is applied as coating or laminate, then mass production becomes possible, but application in fire-prone environments must be ensured

Engineering Contradiction:
Improvemass production capabilityVSAvoidfire extinguishing reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The fire extinguishing agent is pre-applied to substrates in the form of coatings or laminates during the manufacturing process. This preliminary action ensures that the fire extinguishing function is already in place before the product reaches its application environment, guaranteeing reliability while enabling mass production through conventional coating and laminating processes.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention creates composite structures by combining fire extinguishing agents with substrate materials through coating or lamination. This composite approach ensures the fire extinguishing function is integrated into the substrate, maintaining reliability while allowing mass production using existing composite material manufacturing techniques.

Inventive Principle:
Principle #40Composite materials
