Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a metal detector is used to detect metallic objects, then detection capability is achieved, but characterization and imaging capabilities are lost
Solution Approach 1:
The system segments the detection task by using multiple inductive transceiver elements (at least three) arranged at different distances from one another. Each element contributes to forming magnetic fields with different field distributions, allowing the system to detect objects while simultaneously gathering information for characterization and imaging through the control unit's analysis of multiple field interaction patterns.
Solution Approach 2:
The patent transitions from a single-detection-dimension approach to a multi-dimensional approach by arranging transceiver elements at different distances and using various excitation patterns. This creates multiple field distribution dimensions that enable the control unit to infer not only object location but also shape and other characteristics, effectively adding imaging and characterization dimensions to the detection process.
2Measurement precision
If separate detection and characterization techniques are used, then comprehensive object analysis is achieved, but system complexity and time consumption increase
Solution Approach 1:
The patent merges detection, characterization, and imaging functions into a single integrated inductive scanning system. Multiple inductive transceiver elements and a control unit work together to perform all these functions simultaneously using magnetic field interactions, eliminating the need for separate detection and characterization devices and reducing overall system complexity.
Solution Approach 2:
The inductive transceiver elements serve multiple functions: they transmit magnetic fields for detection, receive signals for characterization, and provide data for imaging. The control unit universally processes this information to deliver comprehensive object analysis, making the system multi-functional and reducing the need for specialized separate equipment.
3Measurement precision
If multiple inductive transceiver elements are used to enable imaging, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The system uses at least three inductive transceiver elements segmented at different distances from one another, with each element contributing to forming magnetic fields with different field distributions. This segmentation enables the control unit to infer object location and shape by analyzing the combined field interactions, achieving imaging accuracy without requiring a fully complex multi-modal system.

AI summary
An inductive scanner, especially an inductive shoe and/or foot scanner, is provided. Said inductive scanner comprises at least three inductive transceiver elements for inductively transmitting and/or receiving to form corresponding magnetic fields, and a control unit connected to said at least three inductive transceiver elements. In this context, the at least three inductive transceiver elements are arranged at different distance from one another such that the corresponding magnetic fields between at least one or each respective pair of the at least three inductive transceiver elements have different field distributions in three-dimensional space. In addition to this, the control unit is configured to infer a respective location of an object and/or materials affecting the corresponding magnetic fields on the basis of the different field distributions
