Hall Effect Sensor Triangular Array for Gearbox Position Detection

The patent applies dimensionality change by arranging three Hall effect cells in a triangular configuration rather than using a single sensor. The cells are positioned at different spatial locations (two cells spaced by a first distance along one axis, one cell spaced by a second distance along another axis), enabling the system to detect magnetic field variations from multiple spatial dimensions. This geometric arrangement allows calculation of both rotational and translational positions through mathematical processing of the three voltage signals, thereby achieving two-dimensional position detection with a single sensor assembly.

The patent applies universality by designing a single position sensor assembly with three Hall effect cells that performs multiple functions: detecting both rotational and translational movements of the gearbox selector. The three cells are arranged in a triangular configuration where two cells detect rotational position while the third cell detects translational position. Through mathematical processing of the combined voltage signals from all three cells, the system achieves comprehensive two-dimensional position detection, making the single sensor assembly multi-functional and eliminating the need for separate sensors for different movement types.

The patent applies local quality by orienting each Hall effect cell in a specific direction according to its local position in the triangular arrangement. The first two Hall effect cells are oriented to detect magnetic field variations corresponding to rotational movement, while the third Hall effect cell is oriented to detect variations corresponding to translational movement. Each cell's orientation is optimized for its specific spatial location and detection function, allowing the system to achieve multi-directional detection capability through differentiated local orientations rather than requiring all cells to be omnidirectional or complexly oriented.
