Solution Overview
Problem
Conventional electromagnetic cradles are bulky, noisy, and have complex constructions that make them difficult to assemble and operate smoothly, affecting both caregiver comfort and baby's sleep quality due to inefficient use of space and vibration issues.
Innovation Solution
A compact electromagnetic cradle design featuring a track assembly with two tracks, a sliding assembly with magnet sets and elastic members, and a rocking bed that uses electromagnetic devices to move the bed horizontally, reducing structural space and eliminating vibrations through angled rollers and elastic control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If swinging arms and links are used to drive the rocking bed, then the electromagnetic cradle can achieve reciprocating motion, but the structural space increases and the device becomes bulky
Solution Approach 1:
The patent extracts and eliminates the swinging arms and links from the system, replacing them with a direct electromagnetic driving mechanism. The electromagnetic device is mounted directly on the track assembly and drives the rocking bed through a simplified transmission path, removing the bulky swinging components while maintaining the reciprocating motion function.
Solution Approach 2:
The patent replaces the complex mechanical swinging arm and link system with an electromagnetic driving system. The electromagnetic device generates force directly to drive the rocking bed back and forth, substituting electromagnetic action for the previous mechanical linkage system, thereby reducing structural space while achieving the same motion outcome.
2Ease of operation
If swinging arms are used for driving the rocking bed, then reciprocating motion is achieved, but the construction becomes complicated and assembly becomes difficult
Solution Approach 1:
The patent removes the swinging arms and links from the system, significantly simplifying the construction. The remaining components (track assembly, electromagnetic device, rocking bed) are directly connected with minimal intermediate elements, making the overall construction simpler and easier to assemble while maintaining the reciprocating motion function.
Solution Approach 2:
The patent divides the system into three main functional modules: the track assembly (providing guidance and support), the electromagnetic device (providing driving force), and the rocking bed (carrying the load). This segmentation allows each module to be independently designed, manufactured, and assembled, reducing overall construction complexity.
3Ease of operation
If conventional electromagnetic mechanism is used, then the rocking bed can swing reciprocally, but the swinging arms deflect and vibrate causing unstable operation
Solution Approach 1:
By removing the swinging arms entirely, the patent eliminates the source of deflection and vibration. The rocking bed is driven directly by the electromagnetic device through a stable, rigid connection path, ensuring smooth and stable operation without the oscillations that plagued the swinging arm design.
Solution Approach 2:
The patent replaces the unstable mechanical swinging system with a stable electromagnetic driving system. The electromagnetic force is applied directly to drive the rocking bed, eliminating the intermediate mechanical linkages that caused deflection and vibration, thereby improving operational reliability and smoothness.
