Solution Overview

Problem

Conventional hydroponic cultivation apparatuses require complicated procedures to observe the underground part of a plant, as the partitioning member must be removed to allow visibility, which complicates the observation process.

Innovation Solution

A hydroponic cultivation apparatus with a partitioning portion that has a light shielding property, comprising a fixed member and a door member, where the door member is movable to allow easy access and observation of the underground part without removing the partitioning portion, utilizing elastic members to securely fit around the plant stems and prevent light from reaching the underground area.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a partitioning portion is provided to separate aboveground and underground spaces, then light shielding is improved, but observation of underground part becomes complicated

Engineering Contradiction:
Improvelight shieldingVSAvoidobservation of underground part
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The partitioning portion is divided into a fixed member and a movable door member. The fixed member provides stable light shielding structure, while the door member can be independently opened for observation. This segmentation allows the light shielding function to remain intact while enabling easy access to the underground space for observation purposes.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The door member is designed to be movable relative to the fixed member, transforming the static partitioning structure into a dynamic one. This allows the partitioning portion to switch between closed state (providing light shielding) and open state (allowing observation), resolving the contradiction between maintaining light shielding and enabling observation.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the partitioning portion is made removable to allow observation, then ease of operation is improved, but structural stability deteriorates

Engineering Contradiction:
Improveobservation of underground partVSAvoidstructural stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

By segmenting the partitioning portion into fixed and movable components, the structural stability is maintained through the fixed member while the door member provides controlled access. The fixed member remains in place to ensure structural integrity, while only the door member is removed or opened for observation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The movable door member provides dynamic access without compromising the static stability of the fixed member. The door can be opened when needed and closed when not needed, maintaining structural stability while enabling observation operations.

Inventive Principle:
Principle #15Dynamics

3Reliability

If elastic members are used to secure the partitioning portion, then reliability is improved, but device complexity increases

Engineering Contradiction:
Improvesecure fit around plant stemsVSAvoidnumber of components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The elastic members automatically adjust to fit around plant stems of varying diameters, providing a secure fit without requiring manual adjustment or additional fastening mechanisms. The elastic property allows the members to self-adjust and maintain reliable contact with the stems.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The elastic members utilize material parameter changes (elastic deformation) to adapt to different stem sizes. This allows a single component design to accommodate varying plant dimensions while maintaining reliable securing, avoiding the need for multiple sized components.

Inventive Principle:
Principle #35Parameter changes
