Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If conventional batteries are used for power supply in testing apparatus, then the apparatus can operate portably, but the charge/discharge cycles are limited and waste treatment is required
Solution Approach 1:
The testing apparatus uses solar panels to generate electricity autonomously, eliminating the need for conventional batteries. The system serves itself by converting solar energy directly into electrical energy for operation, achieving unlimited service life without waste treatment requirements.
Solution Approach 2:
The patent replaces the mechanical/chemical battery system with a photovoltaic energy conversion system. Solar panels convert light energy directly into electrical energy, substituting the limited-capacity battery system with an unlimited renewable energy source.
2Reliability
If wired connections are used for data transmission, then reliable data transfer is achieved, but accessibility is limited and maintenance costs increase
Solution Approach 1:
The patent replaces wired mechanical connections with wireless communication technology. Data is transmitted through electromagnetic waves (WiFi, Bluetooth, or other wireless protocols), eliminating physical contact points while maintaining reliable data transfer and improving accessibility.
Solution Approach 2:
The system introduces wireless communication protocols as an intermediary medium for data transmission. Instead of direct physical connections, data passes through wireless signals, enabling remote access and eliminating the need for physical proximity during operation or maintenance.
3Power
If electromechanical devices are used for energy storage and release, then testing functionality is achieved, but electromagnetic noise and switching noise are generated
Solution Approach 1:
The patent replaces electromechanical switching devices with solid-state electronic control circuits. The microcontroller unit manages energy flow through electronic switches (MOSFETs or IGBTs) that operate without mechanical movement, eliminating electromagnetic noise from mechanical commutation and reducing switching noise through controlled gate drive circuits.
Solution Approach 2:
The patent extracts and removes the electromechanical components that generate harmful electromagnetic noise. By using purely electronic energy storage (capacitors) and control mechanisms, the system eliminates the noise-generating mechanical parts while retaining the essential energy storage and release functionality.
4Measurement precision
If comprehensive testing with multiple measurement points is performed, then diagnostic capability is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal testing platform where a single microcontroller-based system performs multiple measurement functions. The same hardware platform can measure frequency response, temporal characteristics, and various electrical parameters by software configuration, eliminating the need for separate dedicated devices for each measurement type.
Solution Approach 2:
The system achieves comprehensive measurement capabilities by dynamically changing measurement parameters through software control. The microcontroller can adjust sampling rates, frequency ranges, and measurement modes based on the specific testing requirements, providing high measurement precision without requiring complex dedicated hardware for each parameter.
