Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the probe uses fixed operating frequencies, then the device structure is simple, but the adaptability to different drilling conditions is reduced
Solution Approach 1:
The patent implements a programmable frequency selection mechanism that allows the probe to dynamically switch between multiple operating frequencies (e.g., 27 kHz, 33 kHz, 40 kHz) based on drilling conditions. The microcontroller reads frequency values from memory and configures the oscillating circuit accordingly, transforming a static fixed-frequency device into a dynamic multi-frequency system that adapts to different industrial electromagnetic interference environments.
Solution Approach 2:
The patent changes the operating frequency parameter of the probe by providing multiple frequency options (27 kHz, 33 kHz, 40 kHz) stored in memory. The system selects and switches between these frequency parameters based on the drilling conditions and interference levels, allowing optimization of signal transmission without physical modification to the probe structure.
2Ease of operation
If the probe parameters are fixed during manufacturing, then the ease of manufacture is improved, but the ease of operation is reduced
Solution Approach 1:
The patent pre-programs multiple frequency values and operational parameters into the probe's memory during manufacturing. This preliminary configuration allows the probe to be ready for various operating conditions without requiring complex manual adjustments or reconfiguration hardware, balancing ease of manufacture with operational flexibility.
3Reliability
If the probe uses a single frequency, then the device complexity is reduced, but the reliability under varying interference conditions is reduced
Solution Approach 1:
The patent makes the probe universal by enabling it to operate at multiple frequencies (27 kHz, 33 kHz, 40 kHz) through a single programmable platform. The microcontroller-based control system can select appropriate frequencies based on interference conditions, making the probe suitable for various drilling environments without requiring multiple specialized probes for different frequency requirements.
