Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional substrate-based methods are used for rooting cuttings, then cuttings can develop roots, but the process is lengthy and results in significant losses
Solution Approach 1:
The invention extracts the essential function of substrate (moisture and nutrient retention) while eliminating the substrate material itself. The biodegradable strip element with pockets provides a substrate-free environment that still delivers the necessary moisture and nutrients through the material's inherent properties, thereby reducing cultivation time and losses without compromising root development.
Solution Approach 2:
The biodegradable strip element changes the physical and chemical parameters of the rooting environment by providing controlled moisture retention and nutrient delivery without the constraints of traditional substrates. This parameter optimization accelerates the rooting process and improves survival rates.
2Productivity
If traditional substrate-based methods are used, then cuttings can be cultivated, but waste materials are generated and environmental friendliness is compromised
Solution Approach 1:
The biodegradable strip element is designed as a disposable, short-living carrier that serves its purpose during the rooting process and then naturally decomposes. This eliminates the need for waste removal and disposal associated with traditional substrates, making the cultivation process environmentally friendly while maintaining high success rates.
Solution Approach 2:
The strip element is discarded after use but in an environmentally benign manner through natural biodegradation. The material breaks down into harmless components, effectively recovering the environmental resource without requiring active waste management interventions.
3Stability of the object's composition
If multiple containers and transplants are used in traditional cultivation, then plants can grow, but the process becomes complex and increases handling requirements
Solution Approach 1:
The invention merges the functions of multiple containers and transplant operations into a single integrated biodegradable strip element. The pockets provide individualized growth environments while the strip itself serves as the carrier, eliminating the need for separate pots and transplanting steps, thereby reducing complexity while maintaining growth stability.
Solution Approach 2:
The biodegradable strip element performs multiple functions simultaneously: it serves as the rooting medium, the container, the support structure, and the eventual planting unit. This multi-functionality simplifies the overall cultivation process while ensuring stable plant development throughout all growth stages.
4Ease of operation
If plastic carrier strips with climate membranes are used, then substrate-free rooting is achieved, but the materials are not biodegradable and create waste
Solution Approach 1:
The invention uses composite biodegradable materials that combine the structural properties needed for substrate-free rooting with the environmental benefits of natural decomposition. The material provides the necessary mechanical support and moisture retention while being fully biodegradable, thus eliminating the waste problem associated with plastic carriers.
Solution Approach 2:
The material parameters are changed from synthetic non-biodegradable plastic to natural biodegradable substances that maintain the necessary structural and functional properties for substrate-free rooting while adding the beneficial property of environmental compatibility through natural decomposition.

AI summary
A method for producing, without the help of a substrate, a plurality of rooted cuttings includes inserting at least one unrooted cutting into pockets arranged successively in a longitudinal direction of a strip element. Each pocket has an opening at a top side facing a transverse direction and a bottom side that is at least partially closed. The strip element is formed at least in part of biodegradable material having a liquid retaining capacity of at least about 100 g liquid per 100 g of biodegradable material dry weight. The strip element has first and second wall-forming members fixed to each other in a spacer area adjacent each pocket and arranged to at least partly overlap in the longitudinal direction and to not fully overlap in the transverse direction. The first wall-forming member extends past the second wall-forming member in the transverse direction at the top side of each pocket.
