Solution Overview

Problem

The growth of plant roots can cause damage to adjacent built-up areas, leading to raised and warped paving stones or road surfaces, and the use of tree discs becomes unsightly and reduces usable space.

Innovation Solution

An installation device with a hollow body having side walls and a lid, featuring openings or perforations, is introduced into the ground around plants, allowing root growth while preventing upward root propagation by filling the device partially before closing it, creating an air space that inhibits root growth towards the surface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If open spaces (tree discs) are left around plantings to protect from root damage, then root damage to paved surfaces is prevented, but the built-up area becomes unsightly and usable space is reduced

Engineering Contradiction:
Improveroot damage to paved surfacesVSAvoidusable paved area
Core Design Contradiction:
Object-affected harmful factorsVSArea of stationary object

Solution Approach 1:

The installation device segments the tree disc area into a structured framework using hollow bodies arranged in a pattern, transforming the open space into a series of contained compartments that can be filled with landscaping material while maintaining paved surfaces between them

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The hollow bodies act as intermediaries between the plant roots and the paved surfaces, providing a structured medium that contains and directs root growth while allowing paved surfaces to be installed in the spaces between the hollow bodies

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If hollow bodies are completely filled with material, then root growth is restricted, but root guidance and natural growth patterns are compromised

Engineering Contradiction:
Improveuncontrolled root growthVSAvoidroot growth flexibility
Core Design Contradiction:
Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The hollow bodies are partially filled with landscaping material rather than completely filled, creating different zones within each hollow body - the lower portion contains material to guide and restrain roots, while the upper portion remains empty to allow natural root spreading and aeration

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

Instead of completely filling the hollow bodies with material, the invention applies partial filling to achieve the desired effect of root guidance while avoiding the negative effects of complete filling, such as restricted root growth and increased weight

Inventive Principle:
Principle #16Partial or excessive action

3Object-affected harmful factors

If the lid is placed immediately after installing hollow bodies, then root growth towards the surface is prevented, but the device complexity and installation steps increase

Engineering Contradiction:
Improveupward root propagationVSAvoidinstallation procedure
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The hollow bodies are installed in the ground first without lids, allowing for easy positioning and alignment. The lids are then placed subsequently, which simplifies the installation process by separating the positioning step from the closing step, reducing overall complexity

Inventive Principle:
Principle #10Preliminary action

AI summary

The planting apparatus has a hollow structure (10) including a bottom wall (18) and sidewalls (12,14) which are arranged vertically from bottom wall. A cover (24) is provided at upper edges of side walls, facing away the bottom wall. Each side wall is formed with openings (22). The side walls are connected with bottom wall. The hollow structure is filled with material such as soil and granule. An independent claim is included for a method for planting plants.
