Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for cultivating rooted cuttings are lengthy, result in losses, and generate waste, and the shipping of substrate-containing plants faces regulatory hurdles and is costly.
Innovation Solution
A biodegradable strip element with alternating wall-forming members forms pockets for unrooted cuttings, facilitating root formation and acclimatization without a substrate, using a biodegradable material that retains moisture and nutrients.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional substrate-based cultivation methods are used, then cuttings can develop roots, but the process is lengthy and results in losses
Solution Approach 1:
The patent extracts the essential function of substrate (moisture and nutrient retention) while removing the substrate itself. The biodegradable strip element with pockets provides a substrate-free environment that still delivers water and nutrients to cutting bases through capillary action and direct contact, eliminating the need for traditional substrates like soil or perlite while maintaining rooting success.
Solution Approach 2:
The biodegradable strip element acts as an intermediary between the cutting and the water/nutrient source. It provides a controlled interface that delivers moisture and nutrients directly to the cutting base without requiring a bulk substrate, mediating the transition from in vitro to in vivo conditions while accelerating root development.
2Reliability
If traditional substrate-based methods are used, then cuttings can be cultivated, but waste materials are generated
Solution Approach 1:
The biodegradable strip element is designed to be discarded after use, but unlike traditional substrates that require disposal of contaminated soil and containers, this strip element biodegrades naturally. The entire strip with residual organic material can be composted or disposed of as organic waste, eliminating the need to discard synthetic containers and contaminated substrates.
Solution Approach 2:
The strip element is a disposable, low-cost carrier made from biodegradable materials that performs its function during the critical rooting phase and then decomposes. This eliminates the need for expensive, reusable substrate systems and their associated cleaning and sterilization requirements, reducing both material waste and processing waste.
3Ease of operation
If substrate-containing plants are shipped, then plants can be transported, but regulatory hurdles and costs increase
Solution Approach 1:
The patent removes the substrate component from the shipping system, leaving only the biodegradable strip element with the plant. This extraction eliminates phytosanitary concerns associated with soil and traditional substrates, allowing plants to be shipped without complex international plant health certificates and regulatory approvals while maintaining transport capability.
4Productivity
If multiple transplanting stages are used, then plants can be cultivated to full size, but outlay and losses increase
Solution Approach 1:
The biodegradable strip element is designed as a segmented structure with multiple pockets that can accommodate cuttings at different growth stages. This segmentation allows for optimized space utilization and reduces the need for multiple transplanting operations, as the strip can accommodate plants from small to larger sizes within the same carrier structure, reducing labor and material costs.

AI summary
A method includes inserting viable, in vitro cultivated plant material into an empty pocket of a strip element that is formed at least in part of biodegradable material. The strip element has a first and second wall-forming member arranged to at least partly overlap in a longitudinal direction and to not fully overlap in a transverse direction with the first wall-forming member extending past the second wall-forming member. The wall-forming members are fixed to each other along a bonding line to delimit a plurality of pockets and a plurality of spacer areas in an alternating arrangement along the longitudinal direction such that a top side of each pocket is open. The method includes facilitating, without the use of a substrate, at least one of an acclimatization or a root formation of the in vitro cultivated plant material in the plurality of pockets of the strip element.
