Solution Overview

Problem

Existing planting container units face issues with maintainability and high manufacturing costs due to complex structures and the need to replace the entire unit when plants die, and they lack stability without additional support.

Innovation Solution

A double-structured planting container unit with an outer and inner container, where the inner container is inserted and fixed to the outer container using a fixing plate, allowing easy replacement and installation, and includes features like a water reservoir and lattice-shaped structure for efficient water circulation and support.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the planting base and plant body are directly provided in the container unit main body, then the structure is simple, but the maintenance is difficult because the whole container unit needs to be removed when the plant dies or is replaced

Engineering Contradiction:
Improvestructure simplicityVSAvoidplant replacement ease
Core Design Contradiction:
Device complexityVSEase of repair

Solution Approach 1:

The container unit is divided into a main body and a removable planting base assembly. The planting base can be extracted from the main body without removing the entire container unit, allowing easy plant replacement while maintaining overall structural simplicity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The planting base is designed as a separate, extractable component from the container unit main body. This extraction design enables the planting base to be removed and replaced independently, solving the maintenance difficulty while keeping the main body structure simple.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of operation

If the container units are disposed by merely placing an upper container unit on a lid of a lower container unit, then the installation is simple, but the container units cannot stand alone without a protective body

Engineering Contradiction:
Improveinstallation simplicityVSAvoidstructural stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The container units are combined with a protective body structure that integrates multiple containers into a stable assembly. The protective body merges the individual containers into a unified structure that can stand alone, while maintaining simple installation procedures.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If a multi-purpose planting base with pressing lid, receiving saucer, and planting pot tray is used, then the versatility is improved, but the structure becomes complicated and the manufacturing cost increases

Engineering Contradiction:
Improvemulti-purpose usabilityVSAvoidnumber of components
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The planting base is designed with universal functionality to serve multiple purposes: it can hold planting pots, be inserted into the container unit main body, and provide structural support. This multi-functionality reduces the need for separate components like pressing lids and receiving saucers, simplifying the overall structure while maintaining versatility.

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

AI summary

A container unit for greening of wall surface and greening method using container unit. The planting container unit has an outer container having an upper-surface and a front-surface opening, an inner container that can be inserted into the front-surface opening of the outer container, and a fixing plate where the inner container is fixed to the outer container. The inner container is capable of housing a planting base, incudes a front-surface opening where a plant body part of the pot plant can be exposed to an outside, and includes an upper-surface opening for housing the planting base and the pot plant. The inner container has, on a front surface having the front-surface opening, a front-surface flange that engages with a wall of the outer container around the front-surface opening. The planting container unit is configured such that the inner container is removably housed inside the outer container.
