Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional infant swing apparatuses are bulky and difficult to move from one room to another due to their large size, lacking convenience and portability.
Innovation Solution
A compact infant swing apparatus design featuring a rearwardly inclined support column and a pivotally connected swing arm with a tapered shape, incorporating a motorized driving mechanism and adjustable seat support, along with wheel assemblies for easy transportation and a carry handle for portability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a large base and traditional swing arm structure are used, then the swing apparatus provides stable pendulum motion, but the apparatus occupies significant space and is difficult to move
Solution Approach 1:
The support column is designed with an inclined configuration rather than a vertical orientation, changing the spatial dimension of the structure. This inclination allows the swing arm to pivot in a compact footprint while maintaining the pendulum motion arc, effectively reducing the horizontal space occupied without compromising motion stability
Solution Approach 2:
The swing arm is designed with a tapered shape that is thicker at the pivot end and thinner at the seat end. This dynamic geometric variation optimizes the moment of inertia distribution, providing stable pendulum motion while minimizing the material volume and overall size of the swing arm component
2Stability of the object's composition
If a large base frame is used, then the swing apparatus remains stable during operation, but it is not convenient to move from one room to another
Solution Approach 1:
The support column inclination redirects the swing motion arc to utilize vertical space more efficiently rather than requiring large horizontal clearance. This dimensional change allows the apparatus to maintain stable operation with a smaller base footprint, improving portability while preserving operational stability
Solution Approach 2:
The base frame is designed with wheel assemblies that segment the overall structure into movable components. This segmentation allows the stable base frame to be easily transported by rolling, resolving the contradiction between maintaining a stable operational base and enabling convenient movement between locations
3Device complexity
If a traditional vertical support column is used, then the structure is simple and straightforward, but the apparatus occupies more space and is less portable
Solution Approach 1:
The support column is configured with a rearward inclination rather than a vertical orientation. This dimensional change in the column's orientation allows the swing arm to pivot in a compact horizontal footprint while maintaining structural simplicity. The inclined column effectively reduces the forward projection of the apparatus, decreasing space occupation without introducing complex mechanical components
