Solution Overview

Problem

Existing raised beds lack flexibility in accommodating varying amounts of soil material based on plant needs, leading to inefficiencies in material usage and design limitations.

Innovation Solution

A modular raised bed border system with interchangeable wall elements and an adjustable intermediate floor, allowing for variable capacity and compact storage, utilizing plug-in connections for easy assembly and disassembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional raised beds with fixed wall elements are used, then the external shape and dimensions are stable, but the soil capacity cannot be adjusted to meet different plant needs

Engineering Contradiction:
Improvesoil capacity adjustmentVSAvoidborder structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The border is divided into multiple interchangeable wall elements of different heights that can be independently selected and combined. Each wall element can be removed and replaced with another of different height, allowing the border to be segmented into sections with varying capacities to match different planting requirements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The wall elements are designed with universal connection features (protrusions and recesses) that allow any wall element to be connected to any adjacent wall element regardless of height. This universal interface enables the same connection system to accommodate multiple configurations and capacity levels.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If deep-rooted plants are planted in conventional raised beds, then sufficient soil volume is provided, but shallow-rooted plants cannot thrive due to excessive soil volume and weight

Engineering Contradiction:
Improveplant type adaptabilityVSAvoidsoil material
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The border is divided into multiple interchangeable wall elements of different heights that can be independently selected and combined. Each wall element can be removed and replaced with another of different height, allowing the border to be segmented into sections with varying capacities to match different planting requirements.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If raised beds are constructed with high wall elements for deep-rooted plants, then large soil volume is accommodated, but storage and packaging space is excessive when not in use

Engineering Contradiction:
Improvecapacity variabilityVSAvoidpackaging volume
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The border is divided into multiple interchangeable wall elements of different heights that can be independently selected and combined. Each wall element can be removed and replaced with another of different height, allowing the border to be segmented into sections with varying capacities to match different planting requirements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Wall elements are designed to nest within each other when stacked for storage. The protrusions and recesses allow shorter elements to be inserted into or alongside taller elements, creating a compact nested arrangement that minimizes packaging and storage volume.

Inventive Principle:
Principle #7Nested doll (Nesting)

4Ease of operation

If modular wall elements with plug-in connections are used, then assembly and disassembly is easy, but connection strength may be reduced compared to permanent joints

Engineering Contradiction:
Improveassembly easeVSAvoidconnection strength
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The border is divided into multiple interchangeable wall elements of different heights that can be independently selected and combined. Each wall element can be removed and replaced with another of different height, allowing the border to be segmented into sections with varying capacities to match different planting requirements.

Inventive Principle:
Principle #1Segmentation

AI summary

The invention relates to a boundary for a raised bed, comprising a plurality of wall elements connected to one another to form a border, each of which has a first end face and an opposite second end face, each of which has fastening elements, wherein each wall element also has a first longitudinal side running between the first end face and the second end face and a second longitudinal side opposite this and also running between the first end face and the second end face parallel to the first longitudinal side, wherein each wall element is connected to an adjacent wall element at its first end face and at its second end face by means of a plug-in connection, wherein each wall element has a cross-section running perpendicular to both opposite longitudinal sides between them, said cross-section comprising alternately arranged first and second sections,wherein the first sections and the second sections extend on opposite sides of the longitudinal central axis of the cross-section with respect to a longitudinal central axis, and wherein an intermediate floor can be arranged perpendicular to the wall elements at a variable height within the boundary formed by the wall elements by engaging it with the first and second sections of opposite wall elements, respectively.
