Solution Overview

Problem

In urban areas, utilizing mains water supply for micro power plants leads to significant water pressure loss and maintenance issues due to the installation of turbines within water pipes, which are costly to compensate and prone to disruptions.

Innovation Solution

A shunt-like coupling system is used, where water from the mains pipeline is diverted to a micro power plant and then feedback through an ejector device, maintaining water pressure and preventing losses, with regulating vents ensuring consistent water feed and suction capacity alignment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If a turbine is installed inside the mains water pipe to generate power, then electric power can be generated from streaming water, but water pressure loss increases substantially

Engineering Contradiction:
Improveelectric power generationVSAvoidwater pressure
Core Design Contradiction:
PowerVSStress or pressure

Solution Approach 1:

The system divides the water flow path into separate segments: the main water supply line remains intact while a side branch connects to the turbine. This segmentation allows power generation without disrupting the main water flow and pressure

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A side branch pipe acts as an intermediary, diverting a portion of water flow to the turbine while the main pipeline continues to supply water at normal pressure. The side branch mediates between the need for power generation and the requirement to maintain water pressure

Inventive Principle:
Principle #24Intermediary (Mediator)

2Power

If a turbine is installed in the water pipe, then power generation is enabled, but maintenance work and errors cause disruption of water supply

Engineering Contradiction:
Improveelectric power generationVSAvoidwater supply continuity
Core Design Contradiction:
PowerVSReliability

Solution Approach 1:

The water supply system is segmented into a main line and a separate turbine branch. This allows the turbine to be maintained or replaced without affecting the main water supply, ensuring continuous water delivery even during turbine maintenance

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The side branch with isolation valves serves as an intermediary pathway that can be independently accessed for maintenance. The valves act as mediators to control flow separation, enabling turbine service without shutting down the entire water supply system

Inventive Principle:
Principle #24Intermediary (Mediator)

3Stress or pressure

If pumps are used to compensate for pressure decrease, then water pressure can be maintained, but costs for the water system increase significantly

Engineering Contradiction:
Improvewater pressureVSAvoidsystem cost
Core Design Contradiction:
Stress or pressureVSEase of manufacture

Solution Approach 1:

The system uses the kinetic energy of the flowing water itself to drive the turbine and generate power, rather than requiring external pumps to maintain pressure. The flowing water serves the dual purpose of power generation and maintaining its own pressure through the side-branch configuration

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The turbine and power generation components are extracted from the main water pressure system and placed in a separate side branch. This extraction eliminates the need for pumps in the main line, avoiding the significant cost increase that would result from adding pressure compensation equipment

Inventive Principle:
Principle #2Taking out (Extraction)
