Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If sensors are arranged in the immediate vicinity of the pump to detect pressure, temperature and flow-rate, then measurement accuracy is improved, but cabling length and cabling effort increase significantly

Engineering Contradiction:
Improvesensor measurement accuracyVSAvoidcabling length
Core Design Contradiction:
Measurement precisionVSLength of stationary object

Solution Approach 1:

The patent introduces a sensor hub module as an intermediary device that collects data from multiple sensors and transmits it to the main controller. This mediator enables sensors to be positioned close to the pump for accurate measurement while the hub consolidates communication, reducing overall cabling requirements between the sensor array and controller.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If circulation pumps are produced in high volumes with standardized design, then production cost is reduced, but customization for individual customer requirements becomes economically unfeasible

Engineering Contradiction:
Improveproduction costVSAvoidcustomization capability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent segments the pump system into modular components: a standardized pump body and a configurable sensor hub module. This segmentation allows the pump hardware to be mass-produced efficiently while the sensor hub can be customized with different sensor configurations to meet individual customer requirements, resolving the contradiction between manufacturing economy and adaptability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sensor hub module provides dynamic configurability through software and sensor selection, allowing the same hardware platform to adapt to different customer needs. This dynamic adaptation enables customization without requiring different pump hardware designs, maintaining production efficiency while meeting diverse requirements.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If connectivity features are integrated into all pump electronics to enable connection to external sensors, then adaptability is improved, but production cost increases due to customization requirements

Engineering Contradiction:
Improveconnectivity capabilityVSAvoidproduction cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The sensor hub module serves as a universal platform that can accommodate multiple sensor types and configurations. This multi-functional design allows a single standardized component to fulfill various connectivity needs across different applications, providing adaptability without requiring custom electronics for each pump variant.

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

Solution Approach 2:

The sensor hub enables dynamic configuration of connectivity features through software control and optional sensor modules. This allows connectivity capabilities to be activated or deactivated based on customer requirements, providing adaptability when needed while maintaining cost-effective standardized production for applications that don't require customization.

Inventive Principle:
Principle #15Dynamics
