Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple magnetic sensors are arranged in close proximity to detect three-axis magnetic fields, then the device can detect magnetic fields in three-axis directions, but magnetic interference occurs between the magnetic sensors
Solution Approach 1:
The patent positions the three magnetic sensors at mutually orthogonal locations on the support structure, utilizing three-dimensional spatial separation. Each sensor is located at a different corner of the rectangular support, with sensing directions aligned along the x, y, and z axes respectively. This spatial arrangement in three dimensions ensures that the magnetic field detected by one sensor does not significantly interfere with the others, while still enabling complete three-axis magnetic field detection capability.
Solution Approach 2:
The support structure is designed with three separate cutouts that independently accommodate each magnetic sensor. This segmentation isolates each sensor within its own designated space, preventing physical and magnetic interference between sensors. Each cutout is positioned at a different location on the support structure, creating distinct sensing zones for each axis while maintaining structural integrity.
2Object-affected harmful factors
If magnetic sensors are positioned to avoid physical interference, then magnetic interference is reduced, but the structural complexity of the support increases
Solution Approach 1:
The rectangular support structure serves multiple functions simultaneously: it provides mechanical strength and structural integrity, creates three separate cutouts for sensor accommodation, establishes precise spatial positioning for orthogonal sensor arrangement, and defines the mounting geometry for the entire magnetic field detection device. This multi-functional design avoids the need for additional complex components while achieving the goal of minimizing magnetic interference.
