Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If a centralized boiler system is used to heat building water, then the system structure is simple and easy to install, but significant heat losses occur during heat transport over large distances

Engineering Contradiction:
Improveheat loss during distributionVSAvoidsystem structure
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The patent divides the centralized heating system into multiple distributed heat pump units, each serving specific zones or recipients within the building. This segmentation eliminates long heat transport distances and reduces distribution losses, while maintaining manageable system complexity through modular deployment

Inventive Principle:
Principle #1Segmentation

2Object-generated harmful factors

If an oil or gas boiler is used for heating, then the system can provide sufficient heating capacity, but it consumes fossil fuels and emits harmful substances

Engineering Contradiction:
Improveemissions of harmful substancesVSAvoidenergy consumption
Core Design Contradiction:
Object-generated harmful factorsVSUse of energy by moving object

Solution Approach 1:

The patent changes the energy source parameter from fossil fuels (oil/gas) to renewable electricity, and changes the heating mechanism parameter from direct combustion to heat pump technology with electrical compression cycles, thereby eliminating harmful emissions while maintaining heating capacity

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent replaces the mechanical combustion system of traditional boilers with an electrical heat pump system that uses electrical compression and phase change mechanisms to generate heat, substituting chemical energy conversion with electrical energy conversion

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

3Loss of energy

If a new heating system is installed to replace the existing boiler, then energy efficiency can be improved, but installation time and cost increase

Engineering Contradiction:
Improveenergy efficiencyVSAvoidinstallation time
Core Design Contradiction:
Loss of energyVSLoss of time

Solution Approach 1:

The patent designs the heat pump units to serve multiple functions including heating water for taps, utility water, and central heating systems, allowing a single infrastructure installation to replace multiple separate systems and reduce overall installation time

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

Solution Approach 2:

The patent utilizes the existing infrastructure (fluid lines, air inlet pipes, flue gas discharge pipes) that has already been installed in the building, performing preliminary preparation work before the heating system renewal to minimize on-site installation time and disruption

Inventive Principle:
Principle #10Preliminary action
