Biodegradable Seedmat With Water-Retaining Pellets for Even Germination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seedmats for growing grass are often expensive, prone to seed loss during handling, and result in uneven growth, lacking features for fast germination and consistent density.
Innovation Solution
A seedmat comprising a biodegradable base and cover layer with a seed distribution, including water-absorbing fertilizer pellets, a bird repellent layer, and a moisture indicator, along with layers to resist animal burrowing and enhance water retention, all manufactured using a centrifugal spray apparatus for even distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing seedmats are used, then grass can be grown, but seeds may fall out during unpacking and handling
Solution Approach 1:
The patent applies preliminary action by pre-attaching seeds to the mat surface before deployment. The seed distribution layer is integrated into the mat structure during manufacturing, ensuring seeds are secured in advance and will not fall out during unpacking or handling operations.
2Manufacturing precision
If existing seedmats are used, then grass growth is achieved, but growth density is uneven
Solution Approach 1:
The patent applies local quality by creating a uniform seed distribution pattern across the entire mat surface. The manufacturing process ensures consistent spacing and density of seeds in different regions of the mat, resulting in uniform grass growth density throughout the deployed area.
3Speed
If existing seedmats are used, then grass can be grown, but germination speed is slow
Solution Approach 1:
The patent applies preliminary action by pre-positioning fertilizer granules adjacent to seeds during manufacturing. This advance preparation ensures that when water is applied, both seeds and fertilizer are immediately available for rapid germination and early growth, eliminating delays associated with separate fertilization steps.
4Ease of manufacture
If existing seedmats are used, then grass growth is achieved, but cost is high
Solution Approach 1:
The patent applies merging by combining multiple functions into a single integrated mat structure. The mat incorporates seed distribution, fertilizer delivery, water retention, and soil stabilization functions all in one product, eliminating the need for separate applications of seeds, fertilizer, and other treatments, thereby reducing overall cost while maintaining high growth efficiency.
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
Ensures fast germination, consistent growth density, and resistance to seed loss, while providing nutrients and moisture retention, making the seedmat efficient and effective for large-scale grass growth.
Implementation Method 1
fertilizer granules or pellets that each have a coating, such as a polymer coating, that enables the pellets to absorb water and to slowly release that water, together with fertilizer
Implementation Method 2
one or more of the layers are treated with or otherwise include biodegradable water retention substances, such as corn starch crystals, that function to retain water and to release that water slowly over a predefined or required time period
Implementation Method 3
the adhesive is applied using a centrifugal spray apparatus with multiple rotating spray heads
