Solution Overview

Problem

Rural communities in developing countries lack access to essential utilities like electricity, clean water, and biogas due to the high cost and inefficiency of traditional grid extension methods, and existing solutions pose health and environmental risks.

Innovation Solution

An autonomous container system with a local controller communicating with a central control system allows for pre-payment of utilities via mobile payment, integrating renewable energy sources and water purification, enabling decentralized and efficient provision of electricity, potable water, and biogas, forming mini-grids that can connect to larger grids.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If grid extension is implemented to provide utilities to remote rural areas, then access to electricity, water and biogas is improved, but the cost becomes prohibitive and economically unreliable

Engineering Contradiction:
Improveaccess to utilitiesVSAvoidcost of grid extension
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system divides the utility provision into decentralized autonomous containers that operate independently rather than extending a centralized grid. Each container serves a local community, eliminating the need for expensive long-distance infrastructure while maintaining reliable utility access.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The autonomous containers are self-sufficient units that generate their own electricity, purify their own water, and produce their own biogas. They manage their own operations and payments through integrated control systems, eliminating dependence on centralized grid infrastructure.

Inventive Principle:
Principle #25Self-service

2Reliability

If decentralized diesel generators are used for power supply, then electricity access is provided, but the operation becomes noisy, dirty and expensive to maintain

Engineering Contradiction:
Improvepower supply accessVSAvoidnoise, pollution and maintenance costs
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The system changes the fundamental parameters of power generation by replacing diesel combustion with renewable energy sources (solar, wind, biomass). This eliminates harmful emissions, reduces noise, and lowers operational costs while maintaining reliable electricity supply.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The autonomous containers integrate multiple energy generation technologies (solar panels, wind turbines, biomass burners) working together in a hybrid system. This composite approach ensures continuous power supply while eliminating the harmful effects of single-source diesel generation.

Inventive Principle:
Principle #40Composite materials

3Illumination intensity

If kerosene lamps are used for lighting, then lighting is provided, but health risks from fumes and fire accidents increase

Engineering Contradiction:
Improvelighting availabilityVSAvoidhealth risks and safety hazards
Core Design Contradiction:
Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The system replaces the mechanical combustion process of kerosene lamps with electrical lighting powered by renewable energy. This substitution eliminates harmful fumes and fire risks while providing adequate illumination through electric bulbs and LEDs.

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

4Ease of operation

If traditional biomass cooking devices are used, then cooking is enabled, but air pollution and health impacts worsen

Engineering Contradiction:
Improvecooking capabilityVSAvoidair pollution and premature deaths
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The system changes the energy source parameter from traditional biomass combustion to clean biogas produced locally. This maintains cooking capability while dramatically reducing air pollution, greenhouse gas emissions, and associated health risks through controlled combustion of cleaner fuel.

Inventive Principle:
Principle #35Parameter changes

5Adaptability or versatility

If pre-payment system is implemented via mobile payment, then payment flexibility is improved for rural users, but payment infrastructure requirements increase

Engineering Contradiction:
Improvepayment flexibilityVSAvoidpayment infrastructure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system uses mobile phones as multi-functional devices that serve both as communication tools and payment instruments. The mobile payment infrastructure leverages existing universal mobile phone penetration in rural areas, eliminating the need for separate payment infrastructure while providing flexible pre-payment options.

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