Solution Overview
Problem
Existing baby rocking chairs primarily offer simple swinging motion and fail to effectively help babies fall asleep quickly, lacking the capability for three-dimensional combined movements.
Innovation Solution
A baby care device incorporating a plane arc motion mechanism and a vertical lifting motion mechanism, which work together to enable the rocking chair frame to make three-dimensional combined movements, simulating a car ride to induce sleep.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a baby rocking chair uses a simple swinging motion around a fulcrum, then the device complexity is low, but the sleep-inducing effect is poor
Solution Approach 1:
The patent transitions from simple one-dimensional swinging motion to three-dimensional combined motion by adding vertical lifting motion to the horizontal arc motion. The seat holder is driven to move both horizontally along an arc trajectory and vertically through lifting mechanisms, creating complex spatial motion patterns that better simulate natural movement and enhance the sleep-inducing effect for babies.
Solution Approach 2:
The patent combines multiple motion mechanisms (arc motion mechanism and vertical lifting motion mechanism) into a unified system where both mechanisms work simultaneously to drive the seat holder. This merging of motion types creates a coordinated three-dimensional motion pattern that is more effective for inducing sleep compared to simple swinging alone.
2Reliability
If a baby rocking chair implements two-dimensional combined movements, then the motion complexity increases, but the sleep-inducing effect remains insufficient
Solution Approach 1:
The patent adds the vertical dimension to the existing two-dimensional horizontal motion, creating true three-dimensional combined motion. The seat holder simultaneously moves in horizontal arc trajectories and vertical lifting directions, achieving comprehensive spatial motion that effectively simulates car ride experiences and significantly improves the sleep-inducing effect.
3Adaptability or versatility
If the plane arc motion mechanism and vertical lifting motion mechanism work together, then the three-dimensional combined movements are achieved, but the device complexity increases
Solution Approach 1:
The patent divides the complex motion system into separate functional modules: the plane arc motion mechanism responsible for horizontal motion and the vertical lifting motion mechanism responsible for vertical motion. Each mechanism is independently designed and controlled, allowing for easier manufacturing, assembly, and maintenance while achieving comprehensive three-dimensional motion capability when both work together.
