Bi-Stable Appliance Actuator With Single-Sensor Position Detection

The single sensor is designed to perform multiple functions: detecting both the first position and the second position of the second component, as well as detecting intermediate positions during transition. This multi-functional sensor replaces what would traditionally require multiple separate sensors, thereby reducing device complexity while maintaining measurement precision across all critical positions.

The sensor utilizes changes in physical parameters (such as magnetic field strength, optical position, or electrical contact state) as the second component moves between positions. By monitoring parameter changes over time, the sensor can determine instantaneous position without requiring multiple sensors at different locations, thus achieving accurate position detection with minimal hardware.

The bi-stable mechanism is designed to maintain the second component in either the first or second position without continuous actuator operation. The mechanism itself provides the stabilizing force through its inherent mechanical design (such as spring-loaded latches or gravitational balance), making the system self-sustaining in each position. The actuator only needs to provide energy during position transitions, not during position maintenance, thereby dramatically reducing energy consumption while preserving position stability.

Instead of continuous actuator operation, the system uses periodic or intermittent actuation only when position changes are required. The bi-stable mechanism naturally maintains positions between actuation events, creating a rhythm of occasional energy input followed by passive maintenance, which minimizes overall energy consumption while ensuring position stability when needed.
