Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If a heating tube is placed in the pump housing to heat water, then heating function is achieved, but fluid efficiency is reduced due to interference between water inflow and outflow

Engineering Contradiction:
Improvewater heatingVSAvoidfluid efficiency
Core Design Contradiction:
TemperatureVSProductivity

Solution Approach 1:

The pump housing internal space is segmented into distinct fluid inlet channel and fluid outlet channel using a flow guiding element. This segmentation prevents interference between incoming and outgoing water flows, maintaining fluid efficiency while accommodating the heating tube for temperature control function.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A flow guiding element is introduced as an intermediary component between the heating tube and the water flow paths. This element creates separated channels that guide water flow around the heating tube, preventing flow interference while allowing the heating tube to perform its heating function effectively.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Temperature

If the heating tube is arranged in the pump housing, then heating capability is provided, but pressure and flow rate losses occur

Engineering Contradiction:
Improveheating capabilityVSAvoidpressure loss
Core Design Contradiction:
TemperatureVSStress or pressure

Solution Approach 1:

The flow guiding element segments the pump housing into separate inlet and outlet channels, creating dedicated pathways for water flow. This segmentation prevents turbulence and pressure losses that would occur if water had to flow around the heating tube in an unguided manner, while still allowing the heating tube to heat the water effectively.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The flow guiding element utilizes the radial and axial dimensions of the pump housing to create three-dimensional flow paths. By guiding water flow in specific radial and axial directions, the system maintains pressure and flow rate while accommodating the heating tube in the available space without causing dimensional constraints on water flow.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
