Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by stationary object

If fuel oil is used to meet energy needs of the wine cellar, then thermal needs are covered, but energy costs increase and greenhouse gas emissions increase

Engineering Contradiction:
Improveenergy costVSAvoidgreenhouse gas emissions
Core Design Contradiction:
Use of energy by stationary objectVSObject-generated harmful factors

Solution Approach 1:

The patent changes the energy source parameter from fossil fuel (fuel oil) to renewable energy (geothermal and solar energy). The heat pumps utilize geothermal energy from the ground, and solar panels capture solar radiation, fundamentally altering the energy input parameter to eliminate harmful emissions while reducing operational costs.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent replaces the combustion-based thermal system with a heat pump system that uses electrical power to drive heat transfer. The heat pumps extract heat from geothermal sources and transfer it to the wine cellar, substituting the chemical combustion process with an electro-thermal system that has no direct emissions.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Use of energy by stationary object

If traditional heating and cooling systems are used separately, then thermal needs are met, but energy efficiency is low

Engineering Contradiction:
Improveenergy efficiencyVSAvoidenergy waste
Core Design Contradiction:
Use of energy by stationary objectVSLoss of energy

Solution Approach 1:

The patent merges the heating and cooling systems into a single integrated heat pump system. The same heat pump can operate in reverse to provide either heating or cooling, eliminating the need for separate systems and reducing energy waste through shared infrastructure and coordinated operation.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent implements a centralized control unit that monitors temperature conditions in real-time and automatically adjusts the heat pump operation. The control system receives feedback from temperature sensors and modulates the heat pump output to match actual thermal demands, preventing energy waste from over-heating or over-cooling.

Inventive Principle:
Principle #23Feedback

3Use of energy by stationary object

If geothermal heat pumps are used to regulate temperatures, then energy efficiency improves, but system complexity increases

Engineering Contradiction:
Improvecoefficient of performanceVSAvoidsystem complexity
Core Design Contradiction:
Use of energy by stationary objectVSDevice complexity

Solution Approach 1:

The heat pump system is designed to perform multiple functions: heating the wine cellar, cooling the wine cellar, and providing domestic hot water. This multi-functionality reduces the need for separate dedicated systems, thereby managing complexity while delivering comprehensive thermal solutions with high efficiency.

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

Solution Approach 2:

The patent introduces a centralized control unit as an intermediary that manages the complexity of coordinating multiple heat pumps and thermal storage tanks. This control system acts as a mediator between the various components, automating the coordination and simplifying operation despite the underlying system complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Reliability

If thermal energy is stored in buffer tanks, then energy availability is improved, but storage space requirements increase

Engineering Contradiction:
Improveenergy availabilityVSAvoidstorage tank volume
Core Design Contradiction:
ReliabilityVSVolume of stationary object

Solution Approach 1:

The patent implements thermal storage with buffer tanks that store energy partially, only to the extent needed for load balancing and peak demand management. The storage capacity is sized to handle typical variations in thermal demand rather than providing excessive storage, thereby maintaining reliability while minimizing the volume of storage tanks required.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

The method involves providing a set of heat pumps (2, 3) e.g. geothermic type heat pump, and recovering temporarily stored calories within a set of volumes (V1, V2) in a surge tank (5) of a structure i.e. viticultural cellar. A part of stored calories is transferred to geothermic energy sources (4a, 4b). A set of negative kilocalories generated by the set of heat pumps and stored in the surge tank is recovered. A part of the negative kilocalories stored temporarily in the surge tank is transferred from the set of heat pumps to the geothermic energy sources. An independent claim is also included for an installation for regulation of temperatures and production of domestic hot water within a structure.
