Solution Overview

Problem

Existing heating systems lack a method to effectively evaluate and display the electrical energy consumption of their components, which is crucial for both user monitoring and operator billing, despite the importance of energy assessment.

Innovation Solution

The control device of the heating system stores and evaluates power consumption data for electrotechnical components, determining current and past electrical energy consumption, and displays it in relation to fuel energy consumption, along with associated costs, using pre-set time intervals and average performance data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If electricity meters are used to accurately measure electrical energy consumption, then measurement precision is improved, but device complexity and cost increase

Engineering Contradiction:
Improveelectrical energy consumption measurement accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent uses a copy of the measurement function by implementing software-based energy consumption calculation in the control device. Instead of installing physical electricity meters, the system creates a virtual model that calculates electrical energy consumption by multiplying power consumption values by operating hours, thereby achieving measurement capability without the complexity of physical metering infrastructure.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent replaces the mechanical/electrical measurement system (physical electricity meters) with an information-processing system. The control device uses stored power consumption data and operating hours counter information to calculate electrical energy consumption, substituting physical measurement infrastructure with computational methods that leverage existing system components.

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

2Measurement precision

If electricity meters are installed for each component, then measurement precision is improved, but ease of operation and installation become more difficult

Engineering Contradiction:
Improveelectrical energy consumption measurement accuracyVSAvoidinstallation and operation convenience
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent merges the energy measurement function with the existing control device that already manages heating system operations. By integrating electrical energy consumption calculation into the central control unit, the system eliminates the need for separate meter installation and simplifies operation, as users can obtain energy consumption information through the existing control interface without additional operational complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The control device performs self-service by automatically calculating and storing electrical energy consumption data using its existing capabilities. The system uses its internal power consumption value storage and operating hours counters to generate energy consumption information without requiring external metering equipment or additional manual measurement operations.

Inventive Principle:
Principle #25Self-service

3Measurement precision

If separate electricity meters are installed for each circuit, then measurement precision is improved, but device complexity and cost increase

Engineering Contradiction:
Improveelectrical energy consumption measurement accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent creates a virtual representation of electrical energy consumption for each component by storing power consumption values in the control device. This virtual model allows the system to track and evaluate energy consumption for individual components (burner, blower, preheating device) without requiring physical separation of measurement equipment, thereby maintaining measurement capability while reducing system complexity.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The control device serves multiple functions: it controls heating system operations, stores power consumption data for various components, tracks operating hours, and calculates electrical energy consumption. This multi-functional approach eliminates the need for dedicated electricity meters for each circuit, as the universal control device performs all measurement and calculation functions centrally.

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