Solution Overview

Problem

Current biogas production systems are inefficient and costly due to the need for large, centralized production plants that require significant workforce and long-distance transportation of biomaterial and biogas, making it difficult to achieve the EU's goal of a comprehensive biomethane refueling network.

Innovation Solution

A system utilizing a biogas reactor with transfer containers adapted for lorry transport, enabling automated and decentralized biogas production and distribution, where biowaste is transported in sealed containers, and biogas is purified and stored for efficient distribution to refueling stations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If large centralized production plants are used, then biogas production capacity is sufficient, but transportation distance of biomaterial and biogas becomes long and operational costs increase

Engineering Contradiction:
Improvebiogas production capacityVSAvoidtransportation distance
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent divides the centralized biogas production system into multiple decentralized modular units. Each module includes a biogas reactor, handling equipment, and transfer containers that can operate independently. This segmentation allows production to be distributed closer to refueling stations, reducing transportation distances for both biomaterial and produced biogas while maintaining sufficient total production capacity through multiple distributed units.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a new spatial dimension by placing biogas production modules directly at or near refueling stations rather than relying on centralized remote plants. This dimensional shift in the production-distribution network transforms the system from a centralized hub-and-spoke model to a distributed network model, fundamentally changing the logistics and transportation requirements.

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

2Productivity

If large centralized production plants are used, then biogas production capacity is sufficient, but workforce requirements and operational costs increase

Engineering Contradiction:
Improvebiogas production capacityVSAvoidworkforce requirements
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The modular units are designed with automated handling equipment that can autonomously load biomaterial into biogas reactors and transfer produced biogas to storage containers. The systems include self-contained control mechanisms and automated monitoring, reducing the need for manual intervention and workforce at each production site while maintaining high productivity through continuous automated operation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The handling equipment and transfer containers are designed as universal, standardized components that can be deployed across multiple modular units. This universality allows for simplified operation and maintenance, as the same equipment design can be operated by similar skill sets across different locations, reducing the overall complexity of workforce requirements for the distributed network.

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

3Extent of automation

If decentralized production with transfer containers is used, then automation is improved and workforce needs are reduced, but requires new handling and transfer equipment

Engineering Contradiction:
Improveautomation levelVSAvoidhandling equipment complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The patent standardizes key parameters of the transfer containers and handling equipment across all modular units, including container dimensions, connection interfaces, and transfer mechanisms. By fixing these parameters, the system achieves high automation through standardized automated handling while avoiding excessive device complexity, as the same standardized equipment can be replicated across multiple units rather than requiring custom complex solutions for each location.

Inventive Principle:
Principle #35Parameter changes
