Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-function underground scanning device is used, then the device structure is simple, but it cannot detect both structural differences and buried metals simultaneously
Solution Approach 1:
The patent combines a magnetic sensor-based detector and a pulse induction-based metal detector into a single integrated device. The magnetic sensor detects structural differences like gaps under the ground, while the pulse induction system detects buried metals. This merging allows simultaneous detection of both types of targets without requiring separate devices.
Solution Approach 2:
The device is designed with multi-functionality to perform both magnetic field detection and metal detection. It includes dual sensor systems that can independently or jointly detect various underground targets, making the device universally applicable for both structural surveying and metal searching operations.
2Ease of operation
If a single-piece main body design is used, then the device structure is simple, but transportation and storage become difficult
Solution Approach 1:
The device is divided into separate functional modules: a magnetic sensor module, a pulse induction module, and a control unit. These modules can be independently assembled and disassembled, allowing the device to be compacted for easy transportation and storage while maintaining full functionality when assembled.
3Measurement precision
If only one sensor is used, then the device structure is simple, but detection sensitivity and detection depth are reduced
Solution Approach 1:
The patent employs dual sensors - a magnetic sensor for detecting structural differences and a pulse induction sensor for detecting metals. By merging the detection capabilities of both sensors, the device achieves enhanced overall detection sensitivity and can detect objects at greater depths compared to single-sensor devices.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device achieves improved detection sensitivity for objects at greater depth distances and facilitates easier transportation and storage due to its modular design, allowing for simultaneous detection of structural differences and buried metals.
Implementation Method 1
When a wire is made into a coil and a current is passed through it, a magnetic field is formed in and around the coil. The magnetic field formed is not visible to the eye. However, the movement of the core inside the coil and the metals brought closer to the coil change the energy storage area of the coil. Magnetic sensors are devices that work on this principle. They detect magnetic changes occurring in their environment.
Implementation Method 2
Magnetic sensors are devices that work on this principle. They detect magnetic changes occurring in their environment. Thus, they produce voltage.
Implementation Method 3
Metal detectors based on the pulse induction system follow a time-controlled oscillator principle that uses alternating current to create a magnetic field in a coil. The magnetic field formed and sent to the ground creates an eddy current and causes a reaction in the buried metal object.
Implementation Method 4
The magnetic field formed and sent to the ground creates an eddy current and causes a reaction in the buried metal object. The electrical conductivity occurring in the metal object is detected as a disorder, i.e., anomaly.
