Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computer-assisted cardiogram diagnostic systems face complexity and error vulnerability due to conflicting diagnostic rules when judging multiple pathologies, making maintenance and updates difficult.
Innovation Solution
A system with a symbol set for cardiogram signal processing, a diagnostic rule library, and a conflict-eliminating binary tree structure to optimize preliminary diagnostic results by discriminating between easily confusable diagnoses and adjusting priority levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If direct logical judgment is used to simulate physician's diagnostic process, then diagnostic functions can be achieved, but the logical structure becomes extremely complicated and vulnerable to mistakes when judging hundreds of pathology types
Solution Approach 1:
The patent segments the complex diagnostic rule system into two distinct modules: a rule management module that stores and manages diagnostic rules in a structured format, and a rule execution module that processes these rules systematically. This segmentation separates rule storage from rule processing, making the overall system more manageable and less complex despite handling numerous pathology types.
Solution Approach 2:
The patent introduces an intermediary rule engine that acts as a mediator between the diagnostic rules and the judgment process. This rule engine systematically manages rule priorities, handles rule conflicts, and coordinates rule execution, thereby simplifying the logical structure while maintaining comprehensive diagnostic coverage.
2Measurement precision
If diagnostic rules are modified through clinical tests, then diagnostic accuracy improves, but the system requires tremendous updates and modifications making maintenance difficult
Solution Approach 1:
The patent implements a dynamic rule management system where diagnostic rules can be easily added, modified, or removed without requiring system-wide updates. The rule management module allows clinical practitioners to adjust diagnostic rules based on clinical test results, and the system automatically adapts while maintaining structural integrity through the intermediary rule engine.
Solution Approach 2:
By segmenting the system into independent rule management and execution modules, the patent enables localized modifications to diagnostic rules without affecting the entire system. This segmentation allows maintenance personnel to update specific rules through the rule management interface without requiring comprehensive system reconfiguration.
3Ease of operation
If expert inference system software is used to register diagnostic rules, then judgment can be executed, but applications are strictly limited due to dependence on the deriving kernel
Solution Approach 1:
The patent creates a universal rule management framework that can handle various types of diagnostic rules and pathology judgments through a single system architecture. The intermediary rule engine is designed to be application-agnostic, allowing the same system to execute different diagnostic rule sets for multiple pathology types without requiring separate expert inference systems for each application.
