Pendulum-Driven Rocking Device for Flexible Attachment Without Stand
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rocking devices for children and infants are inflexible, require a fixed installation, and cannot be easily attached to various types of objects, limiting their universal application and mobility.
Innovation Solution
A device with a holder for attachment to any object, featuring a drive unit and a rod pendulum that can be moved in two opposite directions within a plane, allowing for adjustable rocking movements without the need for stabilization or a dedicated base, using a servo unit and control unit for programmable control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing rocking devices are permanently attached to the object being moved, then the device provides stable rocking motion, but the device loses flexibility and cannot be attached to differently shaped objects
Solution Approach 1:
The holder is designed with adjustable and adaptable characteristics, allowing it to be dynamically configured to fit different object shapes and sizes. The holder can be positioned at different locations and adjusted to accommodate various geometries while maintaining secure attachment and stable rocking motion.
2Adaptability or versatility
If existing devices require a stand for support, then the device provides stable operation, but the device occupies more space and loses mobility
Solution Approach 1:
The stand is extracted and removed from the device design. Instead of requiring a separate support structure, the device attaches directly to the object to be moved, utilizing the object itself as the support base. This eliminates the need for additional space-consuming legs or stabilization elements.
Solution Approach 2:
The holder serves multiple functions: it provides attachment to the object, supports the pendulum mechanism, and eliminates the need for a separate stand. This multi-functional design reduces the overall space requirement while maintaining operational stability.
3Adaptability or versatility
If the pendulum is moved only in one direction, then the device structure is simpler, but the rocking motion is less adjustable and versatile
Solution Approach 1:
The drive unit operates in periodic cycles, moving the pendulum weight back and forth between opposite end positions. This periodic bidirectional movement creates adjustable rocking motions with varying amplitudes and frequencies, providing versatility while maintaining relatively simple control through automated cycling.
