Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a service technician uses traditional test devices to diagnose refrigerator malfunctions, then measurement precision is improved, but device complexity and ease of operation worsen
Solution Approach 1:
The patent creates a virtual copy of the test device functionality within a mobile terminal application. The terminal processor executes test programs that replicate the diagnostic capabilities of traditional test devices, eliminating the need for physical test equipment while maintaining diagnostic accuracy through software-based measurement and analysis.
Solution Approach 2:
The patent replaces the mechanical/physical test device system with an electronic software-based system. The terminal processor, communication unit, and display unit work together to perform diagnostics that traditionally required physical test equipment, substituting mechanical operations with electronic data processing and communication.
2Measurement precision
If a service technician uses traditional test devices to diagnose refrigerator malfunctions, then measurement precision is improved, but ease of operation worsens
Solution Approach 1:
The patent creates a virtual copy of the test device functionality within a mobile terminal application. The terminal processor executes test programs that replicate the diagnostic capabilities of traditional test devices, eliminating the need for physical test equipment while maintaining diagnostic accuracy through software-based measurement and analysis.
Solution Approach 2:
The mobile terminal serves multiple functions: it acts as the test device, display unit, and data processor simultaneously. The terminal processor can execute various test programs for different refrigerator components, making a single device universally applicable for multiple diagnostic tasks that previously required specialized equipment.
3Measurement precision
If the refrigerator is disassembled to test components, then measurement precision is improved, but loss of time and ease of repair worsen
Solution Approach 1:
The patent creates a virtual copy of the test device functionality within a mobile terminal application.
