If conventional pivot sensing circuits use multiple pivot sensors and peripheral circuits, then the pivot angle can be determined, but the device complexity increases

Engineering Contradiction:

Improvepivot angle sensing accuracyVSAvoidnumber of sensors and circuits

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines multiple pivot sensors into a single integrated pivot sensor assembly. The housing integrates multiple contact sensors (first contact sensor and second contact sensor) that detect the position of a single movable ball, replacing the conventional approach of using multiple separate pivot sensors. This merging reduces the number of discrete components while maintaining the ability to determine pivot angles accurately through the coordinated operation of the integrated sensors.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The single pivot sensor housing serves multiple functions: it contains the movable ball, provides structural support, houses multiple contact sensors for detecting different pivot positions, and integrates the sensing mechanism for both horizontal and vertical pivot angles. The first and second contact sensors work together within the same housing to provide comprehensive pivot detection, making the sensor assembly multi-functional rather than requiring separate dedicated sensors for each function.
