Sheep Wool Carrier Plant Brick for Soil Nutrient Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plant bricks with coconut fiber carrier layers are complex and expensive to produce, and they slowly decompose, removing nutrients from the soil, whereas the solution seeks to utilize easily decomposable and locally sustainable materials for a simpler production method and improved soil fertility.
Innovation Solution
The use of needled sheep's wool mats as a carrier layer and soil-independent gardener-standard culture soil without peat or coconut fibers, combined with pre-cultivated plants, to create a plant brick that quickly rots, releases nutrients, and prevents unwanted plant growth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If coconut fiber carrier layers are used in plant bricks, then the structural integrity and durability are improved, but the decomposition time increases and nutrients are removed from the soil
Solution Approach 1:
The patent changes the material composition of the carrier layer from coconut fiber to sheep's wool, fundamentally altering the chemical and biological properties. Sheep's wool contains proteins that decompose more rapidly than the cellulose and lignin in coconut fibers, transforming the decomposition timeline and nutrient release characteristics of the carrier layer
Solution Approach 2:
The patent converts the potential harm of nutrient removal during decomposition into a benefit by selecting sheep's wool that releases nutrients as it decomposes. The protein-based material serves as a natural fertilizer, turning the decomposition process from a nutrient-depleting event into a nutrient-enriching one that benefits soil fertility
2Stability of the object's composition
If coconut fiber carrier layers are used in plant bricks, then the structural stability is improved, but the production complexity and cost increase
Solution Approach 1:
The patent adopts a disposable approach by using sheep's wool mats that are designed to decompose completely in the soil within one to three growing seasons. This eliminates the need for complex, durable construction materials and allows for simpler, more sustainable production processes using locally available materials
Solution Approach 2:
The sheep's wool carrier layer provides self-service functionality by automatically decomposing and releasing nutrients into the soil without requiring external intervention. The material serves multiple functions: structural support during plant growth, moisture retention, and eventual fertilizer release, eliminating the need for separate nutrient management systems
3Speed
If sheep's wool mats are used as carrier layer, then the decomposition speed increases and nutrients are released, but the light tightness and prevention of unwanted plant growth must be ensured
Solution Approach 1:
The patent applies local quality by ensuring that the sheep's wool mat has specific properties at different stages: initially providing light tightness to prevent weed growth, then gradually decomposing to release nutrients. The needled structure creates local density variations that maintain integrity while allowing controlled decomposition
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The plant bricks are cost-effective, easy to produce, promote soil fertility, and require minimal maintenance with a harmonious, long-lasting plant cover that blooms from spring to autumn, reducing maintenance needs.
Implementation Method 1
Another big advantage of the sheep's wool mat is that it can store a lot of moisture, which is beneficial for the planting.
Implementation Method 2
The advantage of the sheep's wool mats compared to the coconut fibers used up to now is that the sheep's wool, which consists largely of proteins, rots more quickly and releases nutrients into the soil. It acts as a fertilizer for the plants throughout the rotting period.

AI summary
The invention relates to a plant brick for laying on soil, the support layer (3) of which consists of a sheep's wool mat and a substrate (2) into which plants (4) are planted. The sheep's wool mat (3), with a thickness between 0.5 cm and 4 cm, consists of needled sheep's wool. A substrate (2) with a layer thickness between 3 cm and 15 cm is applied to the sheep's wool mat (3). Five to fifteen pre-cultivated, perennial ground-covering plants (4) or small shrubs of various kinds are placed in the substrate (2), and three to fifteen geophytes (5) (tubers or bulbous plants) are distributed between the sheep's wool mat (3) and the substrate (2). A solitary perennial plant (6) is arranged in the center of the plant brick (1). The substrate (2) contains no peat or coconut fibers.
