Infant Swing Seat With 2D Sliding Mount for Portable Motion Variety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing infant care devices, such as bouncer seats and swings, often fail to provide sufficient variety in motion to soothe children and are either bulky, non-portable, or lack versatility, limiting their effectiveness in calming infants.
Innovation Solution
An infant care apparatus featuring a base with a concave surface and a sliding mount with a convex surface that allows for relative sliding in two dimensions, enabling the seat frame to swing in multiple directions without a pendulum arm, and can be assembled in a compact size for easy transport, utilizing a driving mechanism with motors and a bearing mechanism to control the motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional swings are used to provide soothing motion, then the calming effect is achieved, but the device becomes large and non-portable
Solution Approach 1:
The device is divided into separable components including a base unit and a swing seat that can be detached and reassembled. This segmentation allows the swing mechanism to be stored compactly when not in use while providing full swing functionality when assembled, resolving the contradiction between portability and device size.
Solution Approach 2:
The swing seat nests within or alongside the base structure when not in use, similar to nested dolls. The curved guide rails and sliding mechanisms are designed to fold or collapse into a compact configuration that fits within a small storage space, enabling easy transport while maintaining full swing motion capability during operation.
2Ease of operation
If bouncer seats are used for infant care, then portability is improved, but the motion variety becomes insufficient and boring
Solution Approach 1:
The device transitions from a static bouncer seat configuration to a dynamic swing mechanism with multiple degrees of freedom. The sliding mount on curved guide rails enables the seat to move in arcs and provide varying motion patterns, transforming the boring repetitive motion into engaging multi-directional swinging that maintains infant interest while preserving portability.
Solution Approach 2:
The invention adds dimensional complexity to the motion by introducing curved guide rails that enable multi-axis swinging movements. Instead of simple up-down or front-back motion, the seat can swing in multiple directions and planes, creating rich motion variety that combines the portability of compact design with the versatility of complex movement patterns.
3Adaptability or versatility
If conventional swings with pendulum arms are used, then swing motion is provided, but the device complexity increases
Solution Approach 1:
The invention extracts and eliminates the complex pendulum arm mechanism from traditional swings. Instead of using rigid arms with joints and connectors, the design employs a simplified sliding mount that moves along curved guide rails integrated into the base. This extraction removes unnecessary structural complexity while preserving the essential swing motion capability.
Solution Approach 2:
The complex mechanical pendulum arm system is replaced with a simpler sliding mechanism guided by curved rails. The motion is achieved through the interaction of the sliding mount with the pre-formed curved guide surfaces, eliminating the need for multiple joints, connectors, and rigid arm structures. This substitution maintains swing functionality while significantly reducing structural complexity and assembly requirements.

AI summary
An infant care apparatus capable of providing various swing motions is disclosed. The infant care apparatus includes a base, a sliding mount, and a seat frame. The base has a concave surface. The sliding mount has a convex surface matching with the concave surface and disposed opposite to the concave surface. The sliding mount slides above the concave surface by the convex surface. The seat frame is fixed on the sliding mount to be moved together with the sliding mount. Thereby, the seat frame together with the sliding mount can swing relative to the base in two dimensions. The infant care apparatus can provide various swing motions without any pendulum arm to child sitting thereon. Besides, the infant care apparatus can be assembled in a compact size facilitating transport.
