Solution Overview

Problem

Existing rooting plugs are unsuitable for (pre-)rooted cuttings and tissue cultured plants due to their tough growing medium, which can cause root damage, and require laborious and time-consuming insertion methods, leading to increased labor costs and potential root damage.

Innovation Solution

A transformable rooting plug with a first shape that is unfolded for easy access and a second shape where the inner surface is folded up onto itself, providing a larger internal surface for root growth and preventing damage, while maintaining dimensional stability and ease of use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the growing medium is made tough to maintain dimensional stability, then the structural integrity of the plug is improved, but root damage occurs during insertion

Engineering Contradiction:
Improvedimensional stabilityVSAvoidroot damage
Core Design Contradiction:
Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The plug transitions from a closed cylindrical shape to an unfolded flat configuration, transforming the growing medium from a rigid confined state to a flexible extended state that can accommodate roots without damage while maintaining dimensional stability when closed

Inventive Principle:
Principle #15Dynamics

2Object-affected harmful factors

If holes are enlarged to accommodate rooted cuttings, then root damage is reduced, but the plant becomes loosely captured and growth stability deteriorates

Engineering Contradiction:
Improveroot damageVSAvoidgrowth stability
Core Design Contradiction:
Object-affected harmful factorsVSStability of the object's composition

Solution Approach 1:

The solution moves from modifying the size of holes in three-dimensional space to unfolding the entire plug structure into a two-dimensional flat configuration, providing a different dimensional approach to root accommodation that maintains both root integrity and plant stability

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Object-affected harmful factors

If sliced plugs or side openings are used to facilitate insertion, then root damage is reduced, but labor time and operational complexity increase

Engineering Contradiction:
Improveroot damageVSAvoidlabor time
Core Design Contradiction:
Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The plug is segmented into an outer surface and an inner surface that can be separated through unfolding, creating distinct functional zones that facilitate easy root insertion while maintaining structural integrity and reducing operational complexity

Inventive Principle:
Principle #1Segmentation

4Area of stationary object

If the inner surface is folded up onto itself, then the surface area for root growth is increased, but the structural complexity increases

Engineering Contradiction:
Improvesurface area for root growthVSAvoidstructural complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The growing medium is configured as a flexible shell that can be unfolded and folded without compromising structural integrity, allowing the inner surface to be folded up onto itself to increase surface area for root growth while maintaining manageable structural complexity through natural folding patterns

Inventive Principle:
Principle #30Flexible shells and thin films

AI summary

Body (1; 101; 201) for cultivation of a plant (2) comprising a growing medium, wherein the body (1; 101; 201) has a longitudinal axis (3) and an external surface (4). The external surface (4) is defined by an upper surface part (5), a lower surface part (6) opposite to the upper surface part (5), an outer surface part (7) and an inner surface part (8) opposite to the outer surface part (7). In a first transition zone (9), one longitudinal side of the inner surface part (8) is connected to one longitudinal side of the outer surface part (7) and, in a second transition zone (10), the other longitudinal side of the inner surface part (8) is connected to the other longitudinal side of the outer surface part (7). The body (1; 101; 201) is transformable from a first shape into a second shape, wherein, viewed in a plane transverse to the longitudinal axis (3), the outline of the second shape is determined by the outer surface part (7) and wherein, in the first shape, the body (1; 101; 201) is unfolded such that the inner surface part (8) is exposed to the surrounding (11) and wherein, in the second shape, the body (1; 101; 201) is folded up such that the inner surface part (8) is folded up onto itself.
