Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If traditional heating and cooling systems are used, then buildings can be maintained at comfortable temperatures, but energy consumption increases and environmental impact worsens

Engineering Contradiction:
Improvebuilding temperature controlVSAvoidenergy consumption
Core Design Contradiction:
TemperatureVSUse of energy by moving object

Solution Approach 1:

The patent introduces an intermediary thermal energy storage system consisting of a storage tank and ground-coupled heat exchanger. This intermediary system mediates between the building's heating/cooling needs and the external environment, allowing thermal energy to be stored and transferred efficiently. The fluid circulation system acts as a mediator to transfer thermal energy between the ground, storage tank, and building, reducing direct energy consumption from traditional HVAC systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system changes the thermal parameters of the fluid circulating through the conduits based on seasonal and daily temperature variations. By adjusting the fluid temperature and flow rate through the ground-coupled heat exchanger and storage tank, the system optimizes heat transfer efficiency. The control system monitors and adjusts these parameters to maximize energy recovery and minimize energy consumption while maintaining comfortable building temperatures.

Inventive Principle:
Principle #35Parameter changes

2Temperature

If traditional heating and cooling systems are used, then buildings can be maintained at comfortable temperatures, but environmental impact increases

Engineering Contradiction:
Improvebuilding temperature controlVSAvoidenvironmental impact
Core Design Contradiction:
TemperatureVSObject-generated harmful factors

Solution Approach 1:

The patent converts the previously wasted thermal energy in HVAC exhaust and cooling water into a beneficial resource. The thermal energy recovery system captures this waste heat or cold and redirects it through the storage tank and ground-coupled heat exchanger to pre-condition incoming air or water. This converts harmful waste thermal energy into a useful resource, reducing the overall environmental impact and energy consumption of the building's heating and cooling systems.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

3Use of energy by moving object

If subfloor conduits and control systems are implemented, then energy efficiency improves, but device complexity increases

Engineering Contradiction:
Improveenergy efficiencyVSAvoidsystem complexity
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The patent segments the thermal energy management system into distinct functional modules: ground-coupled heat exchanger, thermal storage tank, fluid circulation system with pumps and valves, and control system. This segmentation allows each component to be optimized independently and facilitates easier installation, maintenance, and troubleshooting. The modular approach reduces overall system complexity by making each component relatively simple while achieving high energy efficiency through their coordinated operation.

Inventive Principle:
Principle #1Segmentation
