Description

MOTOR SYSTEM IN VERTICAL SWING BABY CRADLE

The technical field in which the invention is included;

The invention is the baby cradle and the new generation motor system of this cradle, which makes vertical oscillating movements similar to the movements of the mother's womb and mother's lap for babies to sleep comfortably.

The motor system consists of a microprocessor-controlled electronic card (2), a DC-powered motor (1), a load/weight cell (3) to determine the instantaneous position of the basket, and a spring to regulate the movements of the cradle

State of the technique;

The cradles available in the market provide a vertical oscillating movement of the motor continuously for a certain period without stopping. This movement of the motor causes both continuous energy consumption and more shaky up and down transitions.

Similar products other than ours cannot detect the instantaneous position of the cradle, so they cannot provide the softness of the spring in the transitions from the bottom to the top. Since it cannot allow the spring to fully reach its maximum point where it will expand depending on the baby's weight, it causes shaking in the transitions from bottom to top. Our invention differs from similar ones in terms of its operating principle.

With our utility model numbered TR 2021/000840, it has been stated that the new generation vertical oscillating motorized baby cradle is designed for babies to sleep comfortably and smoothly. This application is also an invention of our own and has not been seen in the research report. The innovations made in the motor system of the product on the utility model mentioned with our invention are indicated.

Aim of the invention;

With its motor system, it is to ensure that babies feel movements similar to the movements of the mother's womb and mother's lap during sleep and transition to sleep.

Description of the invention;

The invention is the motor system of the baby cradle, which makes vertical oscillating movements similar to the movements of the mother's womb and mother's lap to make babies sleep comfortably.

A microprocessor-controlled electronic card (2), a DC-powered motor (1), a load cell (3) for determining the instantaneous position of the basket, and the cradle are actuated by a spring(4) that provides springing.

There are three potentiometer (5)buttons placed vertically on the control unit. Among these buttons, the top button provides an On/Off Switch and Timing selector, the middle offers Speed Selector, and the bottom one provides Weighing and Calibration functions. By turning the top rotary knob from the Off position to the On position, the system comes to the StandBy position. When the pointer is brought to the full vertical position, the system exits the StandBy position, and the timer (6) values are started to be selected. This means that the system is put in motion mode.

When the switch on the control unit is turned on and brought to the Timer(6) position, the vertical swing movement of the cradle starts automatically without any first external force. The movement that starts automatically is at a low speed in the first seconds and at a higher speed in the next few seconds to not disturb the baby. In the next period, it is ensured that it gradually reaches the speed selected with the speed selector. This automatic starting movement is made with the help of the values measured by the weight sensor integrated into the system. In this way, an automatic oscillating movement that will not disturb the baby is started.

By providing the automatic swing feature to the system, the following features will be gained:

In case the controller is in Stand By position (Switch On, but Timer(6) is not selected) or when the motion stops after the selected timer (6)period is completed: a- With the movement of the baby in the cradle, the weight sensor integrated into the control unit detects the movement. In this case, the motor(l) may start to swing the cradle again at a very low speed and at certain intervals, thanks to its "Automatic Start" capability. b- The baby's crying can be detected, and the cradle can be activated again at a very low speed and specific periods with the "Automatic Mobility" capability.

To measure weight, the top switch must be set to Stand By. Then, the bottom button is moved from the "0" position to the " 1 " position (data acquisition of the tare of the cradle) and then to the "2" position, and the baby is placed in the cradle, and the weight is measured. Considering the baby is moving in the bassinet, the system software measures with a margin of error of around 1%. In Stand By mode, the calibration process of the weight sensor is started by moving the bottom button to the "4" position. Calibration is completed when it is brought to the "3" position from the "4" position (data acquisition of the tare of the cradle), and a 1 Kg weight is placed on the cradle, and then it is brought to the "2" position. In case of an incorrect calibration, an "Incorrect Operation" warning is displayed on the screen(7), and the operation is deemed invalid.

Innovation and Advantages of the Working System;

Load cells(3) are used to make vertical transitions much smoother.

Energy Efficiency: The use of these load cells(3) in our product brings an advantage in terms of energy efficiency. Since the algorithms on the software measure the weights at the lower and upper limits of the oscillation on the vertical axis, it determines how far the oscillation occurs from the stationary point and thus decides whether the motor(l) should be activated or not.

Soft Transitions: The spring (4)on the cradle provides the swing movement. Thanks to this spring(4), the cradle springs(4) and oscillates, and the vertical transitions in this movement are pretty smooth.

The most important of the conditions required for the motor (l)to be activated in our product is to make the maximum expansion of the spring(4) and to determine that the transition from the bottom up has started, thanks to the measurements made with the load cell(3). At this point, the power to be given by the motor' s(l) activation both prevents vibration and ensures that the power produced by the motor(l)is used in the most effective way.

Weight Measurement: Since the load cell (3)constitutes the most crucial part of the working principle of the product and these load cells(3) are used for weight measurement; a scale feature has also been added to our product. In this way, It is an additional innovation that comes with the product, enabling parents to monitor their babies' growth continuously by measuring their babies' weight.

Application to industry;

In addition to the invention's energy efficiency, weight measurement, and soft transition features, it is a vertical swing baby cradle motor system designed for babies to sleep comfortably and smoothly with its automatic movement capability, and it is preferred with its advantages and innovations.
