Infant Swing Control for Detachable Seat Motion Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional swing apparatuses lack the ability to adjust their motor output to accommodate different types of infant holding devices, resulting in suboptimal swing motion for the child's comfort and safety.
Innovation Solution
A swing apparatus with a detachable infant holding device and a control system that includes a motor drive unit and a processing unit, which adjusts the swing motion based on information provided by a detector about the type of infant holding device installed, ensuring the most suitable swing motion is imparted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the swing apparatus uses a fixed motor output, then the structure is simple, but the swing motion is not suitable for different infant holding devices
Solution Approach 1:
The motor output is made dynamically adjustable based on the detected infant holding device type. The processing unit modifies motor drive signals in real-time according to detector information, allowing the swing motion parameters to adapt to different device characteristics while maintaining a relatively simple overall system structure.
Solution Approach 2:
The system changes motor output parameters (such as speed, torque, or oscillation amplitude) based on the detected type of infant holding device. The processing unit receives detector information and adjusts motor drive signals accordingly, enabling the same motor to provide optimal performance for different device types without requiring multiple motors or complex mechanical configurations.
2Adaptability or versatility
If the swing apparatus accommodates multiple infant holding devices, then the versatility is improved, but the motor output control becomes inadequate
Solution Approach 1:
The detector provides feedback information about the installed infant holding device type to the processing unit. This feedback loop enables the system to automatically adjust motor output parameters to match the specific requirements of each device type, ensuring reliable and appropriate swing motion control across multiple device configurations.
Solution Approach 2:
The swing apparatus is designed with universal compatibility for multiple infant holding device types through a single motor system. The processing unit acts as a universal controller that can interpret detector information from various device types and generate appropriate motor drive signals, allowing one motor to reliably serve multiple functions across different device configurations.
3Ease of operation
If the motor output is adjusted according to device type, then the swing motion comfort is improved, but the control system complexity increases
Solution Approach 1:
The swing apparatus automatically determines the appropriate swing motion parameters through the detector and processing unit without requiring manual user configuration. The system self-adjusts motor output based on the detected infant holding device type, providing comfortable swing motion while minimizing user interaction and keeping the control interface simple.
Solution Approach 2:
The detector identifies the infant holding device type in advance before the swing motion begins. The processing unit uses this preliminary information to pre-configurate the motor output parameters, ensuring that the swing motion is immediately optimized for comfort when the device is installed, without requiring trial-and-error adjustments or complex real-time sensing during operation.

AI summary
A swing apparatus is adapted to receive the installation of a variety of infant holding devices, such as portable infant seats and bassinets. The infant holding device can be desirably installed and removed from the swing apparatus. In certain embodiments, the support frame of the swing apparatus can be provided with a detector adapted to provide information about the installed infant holding device, in particular an identified type thereof. According to this information, the output of a motion drive unit that is operable to swing the infant holding device can be adjusted to set a suitable swing motion.
