Solution Overview

Problem

Conventional methods of Sphagnum cultivation are resource-intensive, inefficient, and environmentally harmful, requiring significant water usage, complex infrastructure, and are not sustainable, while Sphagnum is believed to tolerate only low nutrient conditions.

Innovation Solution

A method for cultivating Sphagnum using a nutrient composition comprising nitrogen, phosphorus, and/or potassium, which can be supplied through irrigation, allowing for improved growth and reducing environmental impact.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional paludiculture techniques are used to grow Sphagnum by raising the water table, then optimal Sphagnum growth is achieved, but significant amounts of water are wasted and infrastructure complexity increases

Engineering Contradiction:
ImproveSphagnum growthVSAvoidwater waste
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The patent changes the nutrient parameter from low-nutrient (conventional) to high-nutrient composition, allowing Sphagnum to thrive without requiring water table manipulation. This parameter change in nutrient supply enables alternative cultivation methods that don't waste water.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent extracts the essential requirement for water table manipulation from the cultivation system by providing nutrients directly to the Sphagnum through irrigation, eliminating the need for ditches, banks, and underground piping infrastructure.

Inventive Principle:
Principle #2Taking out (Extraction)

2Productivity

If conventional paludiculture techniques are used with ditches and banks to raise water table, then Sphagnum growth is maintained, but site area available for productive crop is reduced to approximately 50%

Engineering Contradiction:
ImproveSphagnum growthVSAvoidproductive crop area
Core Design Contradiction:
ProductivityVSArea of stationary object

Solution Approach 1:

The patent removes the requirement for ditches and banks from the cultivation system by providing nutrients through irrigation, thereby eliminating the infrastructure that consumed 50% of the site area and increasing the productive crop area.

Inventive Principle:
Principle #2Taking out (Extraction)

3Productivity

If conventional methods remove top layer soil and level sites to form ditches and banks, then water table can be raised, but preparation cost increases to over £10,000 per hectare

Engineering Contradiction:
ImproveSphagnym growthVSAvoidsite preparation cost
Core Design Contradiction:
ProductivityVSEase of manufacture

Solution Approach 1:

The patent extracts the expensive site preparation steps (removing top layer soil, leveling, forming ditches and banks) from the cultivation method by using nutrient irrigation that doesn't require water table manipulation, thereby reducing preparation costs.

Inventive Principle:
Principle #2Taking out (Extraction)

4Productivity

If excess water is applied through underground pipes to raise water table, then Sphagnym growth conditions are created, but surrounding areas may experience crop flooding

Engineering Contradiction:
ImproveSphagnym growthVSAvoidcrop flooding
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent applies nutrients locally to the Sphagnym through irrigation rather than flooding the entire area with excess water, thereby providing necessary growth conditions without causing harmful flooding to surrounding crop areas.

Inventive Principle:
Principle #3Local quality

5Productivity

If conventional methods are used to cultivate Sphagnym under low nutrient conditions, then growth is maintained, but water usage increases significantly

Engineering Contradiction:
ImproveSphagnym growthVSAvoidwater usage
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

The patent changes the nutrient parameter from low-nutrient to high-nutrient composition, which allows Sphagnym to achieve optimal growth with reduced water requirements, as nutrients are provided directly through irrigation rather than requiring water table saturation.

Inventive Principle:
Principle #35Parameter changes
