Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If new communication technologies are integrated into centrifugal pump units to expand functional scope, then the functionality and adaptability are improved, but the development time and certification duration increase

Engineering Contradiction:
Improvefunctional scopeVSAvoiddevelopment time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system is divided into a base pump unit and separate electronic extension modules. Each module can be independently developed, tested, and certified. This segmentation allows new communication technologies to be added via modules without requiring recertification of the entire pump system, thus reducing development time while expanding functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A universal electrical interface and communication protocol are defined that can accommodate multiple different communication technologies (BACnet, MODBUS, and future technologies). This allows a single modular platform to support diverse functionalities without requiring separate development cycles for each technology.

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

2Adaptability or versatility

If electronic extension modules are added to expand functionality, then the adaptability is improved, but the device complexity increases

Engineering Contradiction:
Improvefunctional scopeVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

By defining a universal electrical interface and standardized communication protocol, the system achieves multi-functionality without proportionally increasing complexity. The same interface structure handles different communication protocols, and the modular design allows functions to be added without redesigning the entire system architecture.

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

Solution Approach 2:

The electronic extension module acts as an intermediary between the pump control electronics and various communication technologies. This intermediary layer handles protocol-specific complexity internally while presenting a unified interface to the pump system, thus isolating complexity within modular components rather than the entire system.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If multiple communication technologies are integrated to meet customer needs, then the adaptability is improved, but the manufacturing cost increases

Engineering Contradiction:
Improvefunctional scopeVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

By segmenting communication technologies into separate extension modules, manufacturers can produce a standardized base pump unit at low cost and then add only the specific communication modules needed for each application. This avoids the cost of integrating all possible communication technologies into every pump unit, thereby reducing manufacturing costs while maintaining adaptability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different communication functionalities are provided locally through specific extension modules rather than being uniformly distributed across all pump units. This allows each pump to be equipped with only the communication capabilities it needs, optimizing the balance between functionality and manufacturing cost.

Inventive Principle:
Principle #3Local quality
