Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If conventional hot water heating systems are used, then heating can be provided, but a lot of heating energy is wasted and large pipe diameter requires enormous amount of water in the system

Engineering Contradiction:
Improveheating energyVSAvoidwater in the system
Core Design Contradiction:
Loss of energyVSQuantity of substance

Solution Approach 1:

The patent extracts the heating function from the conventional hot water heating system and implements it directly at the plant root level through heating elements integrated into the tabletop structure. This eliminates the need for large-diameter pipes and extensive water circulation, thereby reducing both energy waste and water quantity in the system.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The heating system provides localized heating directly at the plant root area through heating elements embedded in the tabletop, rather than heating the entire greenhouse air space. This local quality approach ensures heating energy is delivered precisely where needed, minimizing energy waste and reducing the overall water requirement in the heating system.

Inventive Principle:
Principle #3Local quality

2Reliability

If metal pipes are used for heating, then heating can be provided, but pipes corrode due to the material and can lead to contamination of the heating medium

Engineering Contradiction:
Improveservice life of heating systemVSAvoidcorrosion and contamination
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent replaces durable but corrosive metal pipes with cheaper, non-corrosive plastic hoses that have sufficient service life for the application. These plastic hoses eliminate corrosion and contamination risks while being cost-effective and easy to replace if needed.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The heating system uses plastic hoses instead of metal pipes, utilizing the corrosion-resistant properties of plastic materials. This material substitution eliminates the harmful effects of corrosion and contamination while maintaining the heating function.

Inventive Principle:
Principle #40Composite materials

3Loss of energy

If floor heating systems are used, then room temperature can be reduced by supplying heat directly where needed, but complex assembly is required including vibrating devices and tension-carrying cables

Engineering Contradiction:
Improveheating energy efficiencyVSAvoidassembly complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The patent combines the heating elements directly into the tabletop structure itself, merging the support function and heating function into a single integrated unit. This eliminates the need for separate complex assembly components like vibrating devices and tension-carrying cables, while still achieving efficient localized heating at the plant root area.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The heating elements are pre-integrated into the tabletop structure during manufacturing, so that when the tabletop is installed, the heating system is already in place and ready for use. This preliminary action eliminates the need for complex on-site assembly operations.

Inventive Principle:
Principle #10Preliminary action

4Loss of energy

If heating mats are used with screed layer, then heating can be provided, but shrinkage is not taken into account leading to cracking in the screed layer

Engineering Contradiction:
Improveheating energy distributionVSAvoidcracking in screed layer
Core Design Contradiction:
Loss of energyVSManufacturing precision

Solution Approach 1:

The patent uses a cement-bound leveling layer that is applied over the heating elements and is designed to accommodate shrinkage and movement. This preliminary preparation of the leveling layer prevents cracking by allowing for material shrinkage while maintaining a smooth, level surface.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent changes the material properties of the leveling layer by using cement-bound material that can accommodate shrinkage without cracking. This parameter change in material selection and properties allows the leveling layer to maintain integrity while providing a smooth surface for plant containers.

Inventive Principle:
Principle #35Parameter changes

5Loss of energy

If conventional heating systems are used, then heating can be provided, but homogeneous heat distribution under plant bowls is not achieved

Engineering Contradiction:
Improveheat distribution efficiencyVSAvoidheat distribution uniformity
Core Design Contradiction:
Loss of energyVSManufacturing precision

Solution Approach 1:

The patent implements heating elements that are positioned and configured to provide localized heating directly under each plant bowl or container. This local quality approach ensures homogeneous heat distribution to each plant's root area, optimizing heating efficiency and plant growth.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent transitions from conventional air-based heating to direct contact heating through the tabletop structure, adding a new dimension of heat transfer. The heating elements are embedded in or attached to the tabletop, providing heat directly to the plant containers through the table surface, achieving uniform heat distribution.

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