Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cuttings are cultivated in substrates in small containers and then transplanted into larger containers, then the cuttings can develop roots, but the process becomes lengthy and results in losses
Solution Approach 1:
The invention extracts the substrate from the rooting process entirely. The biodegradable strip element serves as a carrier that provides moisture retention and structural support without requiring traditional substrates like soil or perlite. This eliminates the need for multiple transplantation steps between different substrate types and container sizes, significantly reducing cultivation time while maintaining high rooting success rates.
Solution Approach 2:
The biodegradable strip element is pre-formed with multiple pockets before the cuttings are inserted. The strip element is already prepared with the correct structure, moisture retention properties, and biodegradation characteristics needed for successful rooting. This preliminary preparation eliminates the need for sequential transplantation into progressively larger containers, as the strip element accommodates the entire rooting and early growth process in one configuration.
2Reliability
If traditional substrate-based methods are used, then cuttings can be rooted, but waste materials are generated and environmental friendliness is compromised
Solution Approach 1:
The invention changes the material parameter of the carrier from traditional non-biodegradable substrates (plastic, synthetic materials) to biodegradable materials. This parameter change transforms the waste generation characteristic, as the biodegradable strip element breaks down naturally after serving its purpose, eliminating the waste problems associated with traditional substrate materials while maintaining effective rooting capabilities.
Solution Approach 2:
The biodegradable strip element is designed as a single-use, disposable carrier that performs its function during the rooting process and then naturally decomposes. This approach eliminates the need for recycling or disposal of traditional substrate materials, as the biodegradable strip element returns to the environment harmlessly after use, significantly reducing waste generation while ensuring reliable rooting effectiveness.
3Quantity of substance
If multiple transplantation steps are performed, then cuttings can be cultivated to larger sizes, but cultivation outlay and complexity increase
Solution Approach 1:
The biodegradable strip element serves multiple functions simultaneously: it provides structural support for the cutting, retains moisture around the root zone, facilitates gas exchange, and serves as a temporary carrier that can be directly planted in the final location. This multi-functionality eliminates the need for multiple separate containers and transplantation steps, reducing cultivation process complexity while still enabling plants to grow to larger sizes.
4Reliability
If conventional substrate methods are used, then cuttings can be transported to customers, but transportation costs increase and phytosanitary compliance becomes more difficult
Solution Approach 1:
The invention changes the weight parameter of the carrier system by eliminating heavy traditional substrates. The biodegradable strip element is significantly lighter than substrate-filled containers, reducing transportation weight and associated costs. Additionally, the simplified structure and biodegradable nature of the strip element facilitate phytosanitary compliance by reducing the risk of invasive species transport and simplifying regulatory requirements.

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.
