Sensory Integration Carousel With Screwless Rotation-Shaft Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensory integration carousels suffer from unstable connections and low safety due to screws loosening, posing a risk of tipping over and slipping during use.
Innovation Solution
A sensory integration carousel with a base unit and carousel unit featuring an integrated carrying and connecting structure, where the carousel unit is connected via a rotation shaft to the base unit, ensuring a stable and reliable connection without screws, and designed to provide both horizontal and vertical sensations for enhanced sensory stimulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If screws are used to connect the connecting member and carousel, then the assembly is easy, but the connection becomes unstable and unsafe after long use
Solution Approach 1:
The connecting member and carousel are merged into an integrated structure where the connecting member forms part of the carousel assembly, eliminating separate screw connections and ensuring permanent, stable connection without loosening over time
Solution Approach 2:
The carousel is divided into distinct functional segments (base unit, connecting member, carousel unit) that can be assembled through an integrated connection mechanism, allowing easy assembly while maintaining permanent stability through the design of the connecting structures themselves
2Device complexity
If the connecting member is detachably connected via screw, then the assembly is simple, but the safety decreases due to loosening and falling off
Solution Approach 1:
The connecting member and carousel are merged into an integrated structure, eliminating the need for separate fasteners and ensuring the connection cannot loosen or fall off, thereby removing the safety hazard while maintaining structural simplicity
Solution Approach 2:
The integrated connection design preemptively prevents the harmful effect of screw loosening and detachment by eliminating the connection interface that could fail, ensuring safety before any potential failure could occur
3Ease of manufacture
If the carousel unit is connected horizontally, then the installation is simple, but the sensory stimulation is insufficient
Solution Approach 1:
The connecting member is designed with rotational capability, allowing the carousel unit to move from a static horizontal position to dynamic angled positions, creating both horizontal and vertical motion sensations that enhance sensory stimulation while maintaining simple installation
Solution Approach 2:
The connection mechanism extends from simple horizontal alignment to three-dimensional angular positioning, adding vertical and rotational dimensions to the connection, thereby creating multiple sensory experiences (horizontal rotation, vertical rise and fall) while keeping the installation process simple
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enhances stability and safety, providing comprehensive sensory stimulation and increased fun during play, while preventing children from being easily ejected under centrifugal force, thus improving the overall safety and effectiveness of sensory integration training.
Implementation Method 1
when the children ride in the carousel unit to rotate the body, the children not only can experience the feeling of the horizontal rotation, but also can experience the feeling of the rise and fall
