Solution Overview

Problem

Current domestic water supply pumping devices are inflexible in installation configuration, occupy excessive space, and are noisy due to bulky components and fan-based cooling systems, requiring extensive surveys and complex assembly processes.

Innovation Solution

A compact, all-in-one pumping device with a centrifugal electric pump, tank, and manifold enclosed in a single box-like body, featuring adaptable quick-fixing mechanisms and perpendicular intake and delivery connectors, allowing horizontal or vertical installation, and eliminating fan-based cooling systems for reduced noise and space occupation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional pumping assemblies are designed for fixed vertical or horizontal installation, then the pump structure is simplified, but the installation flexibility is reduced

Engineering Contradiction:
Improveinstallation flexibilityVSAvoidassembly configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The pump housing is designed with universal mounting features that allow the pump to be installed in multiple orientations (vertical, horizontal, and intermediate angles). The intake and delivery ports are positioned to accommodate different piping configurations, enabling a single pump model to serve multiple installation scenarios without requiring orientation-specific variants.

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

Solution Approach 2:

The pump assembly is divided into modular components including the pump housing, motor assembly, base plate, and mounting brackets. These segmented components can be independently positioned and oriented during installation, allowing the installer to configure the pump in different orientations while maintaining proper alignment of internal components.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If components are pre-assembled on a single footing, then installation is simplified, but the space occupation increases

Engineering Contradiction:
Improveinstallation easeVSAvoidspace occupation
Core Design Contradiction:
Ease of operationVSVolume of stationary object

Solution Approach 1:

The pump components are arranged in a nested configuration where the delivery housing partially encloses the motor assembly, and the base plate integrates mounting surfaces for both the pump and motor. This nested arrangement minimizes the overall footprint of the assembled unit while keeping all essential components accessible for installation and maintenance.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The pump utilizes vertical space efficiently by positioning the motor above the pump housing and using the vertical dimension for component stacking. The base plate extends in multiple directions to provide mounting surfaces, allowing the assembly to occupy minimal floor space while maintaining ease of installation through standardized mounting holes and alignment features.

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

3Object-affected harmful factors

If fan-based cooling systems are used for the motor, then cooling effectiveness is improved, but noise level increases

Engineering Contradiction:
Improvenoise levelVSAvoidmotor cooling
Core Design Contradiction:
Object-affected harmful factorsVSTemperature

Solution Approach 1:

The mechanical fan-based cooling system is replaced with a passive thermal management approach. The motor housing incorporates heat dissipation fins and thermal pathways that conduct heat from the motor windings to the external environment. This eliminates the need for rotating fans, significantly reducing noise levels while maintaining adequate cooling through natural convection and radiation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The motor cooling system operates autonomously without mechanical actuators. Heat generated by the motor is automatically dissipated through thermally conductive pathways and surface area expansion via fins. The system self-regulates based on operating conditions, eliminating noise-generating moving parts while maintaining effective thermal management.

Inventive Principle:
Principle #25Self-service

4Reliability

If bulky detection devices and cooling systems are included, then functional reliability is improved, but device compactness is reduced

Engineering Contradiction:
Improvefunctional reliabilityVSAvoiddevice compactness
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The detection devices and cooling components are integrated into the pump housing structure itself. Pressure sensors are embedded in the housing walls, temperature sensors are positioned within the motor assembly, and heat dissipation features are incorporated into the housing design. This merging of functions eliminates the need for separate bulky components, maintaining reliability while achieving compact dimensions suitable for domestic installations.

Inventive Principle:
Principle #5Merging (Combining)
