Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an external signal source and PC-based control system are used, then measurement functionality is achieved, but portability and field endurance deteriorate
Solution Approach 1:
The patent merges the signal source, data acquisition system, and control functions into a single integrated portable instrument. The microcontroller unit combines multiple functions that were previously separated into different components (PC, external signal source, acquisition system), enabling the instrument to be carried and operated in field conditions without sacrificing measurement capabilities.
Solution Approach 2:
The portable instrument is designed with multi-functionality, incorporating signal generation, data acquisition, processing, and display capabilities within a single device. The microcontroller unit can perform multiple tasks including controlling the signal source, acquiring impedance data, processing measurements, and interfacing with display devices, eliminating the need for separate specialized equipment.
2Ease of operation
If Bluetooth communication is used for wireless control, then remote operation is enabled, but data transmission speed deteriorates
Solution Approach 1:
The patent introduces a dual-communication architecture where Bluetooth serves as an intermediary for command transmission from the mobile device to the instrument, while a separate high-speed data interface handles bulk data transfer. This intermediary approach allows Bluetooth's wireless convenience to be combined with faster data transmission capabilities through the additional communication channel.
3Speed
If wired control is used, then data transmission speed is maintained, but remote measurement capability deteriorates
Solution Approach 1:
The communication system is designed dynamically, allowing the instrument to switch between wired and wireless communication modes based on operational requirements. The microcontroller unit can establish connections through multiple interfaces (Bluetooth for remote control, and high-speed wired interfaces for rapid data transfer), adapting the communication method to the specific measurement scenario.
4Device complexity
If software is limited to receiving data only, then system complexity is reduced, but data processing and visualization functionality deteriorates
Solution Approach 1:
The patent merges data reception, processing, and visualization functions into the portable instrument itself. The microcontroller unit not only receives raw impedance data but also performs processing calculations and controls display devices to present results in graphical formats. This integration eliminates the need for complex external software systems while providing comprehensive automated data handling capabilities.
