Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If pressurized trucks are used for bulk powder transportation, then delivery capability is achieved, but operational cost increases and safety decreases

Engineering Contradiction:

Improvedelivery capabilityVSAvoidoperational safety

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the pressurization function from the transportation system by removing the need for pressurized trucks. Instead, a flexible container with a fluidizing system is used that operates without external pressurization, thereby eliminating the safety hazards associated with high-pressure operations while maintaining bulk powder delivery capability

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the mechanical pressurization system with a fluidizing system that uses air injection through distributor plates. This substitution eliminates the need for pressurized vehicles and their associated safety risks, while still achieving efficient bulk powder transportation and discharge

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If pressurized trucks are used for bulk powder transportation, then delivery capability is achieved, but operational cost increases

Engineering Contradiction:

Improvedelivery capabilityVSAvoidoperational cost

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The patent extracts the expensive pressurization requirement from the transportation system. By using a flexible container that can be loaded and discharged without pressurized trucks, the operational cost is significantly reduced while maintaining the ability to deliver bulk powders efficiently

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent employs a flexible container system that can be easily deployed and discarded or reused without the need for expensive pressurized vehicle infrastructure. This approach replaces costly pressurized truck operations with a more economical flexible container solution

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Reliability

If pressurized trucks are used for bulk powder transportation, then delivery is achieved, but delivery time increases

Engineering Contradiction:

Improvedelivery capabilityVSAvoiddelivery time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent incorporates a fluidizing system with distributor plates that are pre-installed in the flexible container. This preliminary preparation allows for rapid fluidization and discharge of bulk powders when needed, reducing the time required for loading and unloading operations compared to traditional pressurized truck methods

Inventive Principle:

Principle #10Preliminary action

4Reliability

If pressurized trucks are used for bulk powder transportation, then delivery capability is maintained, but adaptability decreases

Engineering Contradiction:

Improvedelivery capabilityVSAvoidoperational versatility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent designs a flexible container system that can be used for various bulk powder transportation applications without requiring specialized pressurized vehicles. The flexible container with fluidizing system can adapt to different locations and operational requirements, providing universal applicability across multiple use cases

Inventive Principle:

Principle #6Universality (Multi-functionality)
