Solution Overview
Problem
Determining the nominal output and thermal coupling parameters of an unknown radiator for an electronic heat cost allocator is time-consuming due to the vast variety of radiators lacking type plates, making precise heat emission measurement challenging.
Innovation Solution

Engineering Contradiction Analysis
1Measurement precision
If manual determination methods are used for nominal output and thermal coupling parameters of unknown radiators, then measurement precision can be maintained, but time consumption increases significantly
Solution Approach 1:
The patent applies preliminary action by pre-storing radiator templates with nominal outputs and thermal coupling parameters in a database before actual measurement needs arise. When an unknown radiator needs parameterization, the system automatically compares the radiator's shape against pre-stored templates and retrieves parameters without manual measurement, thus maintaining precision while dramatically reducing time consumption.
Solution Approach 2:
The patent uses copying by creating digital shape representations (copies) of radiators and storing them in a database. Instead of manually determining parameters for each unknown radiator, the system creates a shape copy, compares it against stored templates, and copies the associated parameters from the matching template, eliminating time-consuming manual determination while preserving measurement accuracy.
2Measurement precision
If radiator type plates are required for accurate parameter determination, then parameter accuracy is ensured, but ease of operation deteriorates due to missing type plates on most radiators
Solution Approach 1:
The patent replaces the mechanical/manual system of reading type plates with an automated image processing and pattern recognition system. The system captures images of radiators, processes them computationally to extract shape parameters, and automatically matches them against stored templates to determine nominal output and thermal coupling parameters, eliminating the need for physical type plates and manual operations.
Solution Approach 2:
The patent introduces an intermediary - a computer-based image processing and pattern recognition system - between the unknown radiator and the parameter determination process. This intermediary automatically extracts shape features from radiator images, compares them against stored templates, and retrieves parameters, thereby eliminating the need for direct manual intervention or physical type plates while maintaining accuracy.
3Measurement precision
If comprehensive radiator databases with multiple parameters are maintained, then parameterization accuracy improves, but device complexity increases
Solution Approach 1:
The patent applies taking out by extracting only the essential shape parameters needed for template matching from comprehensive radiator databases. Instead of storing and processing all possible radiator parameters, the system identifies and extracts key shape features that are sufficient for accurate parameter determination, thereby reducing database complexity and processing requirements while maintaining parameterization accuracy.
