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

VSEngineering 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

Engineering Contradiction:
Improveflexibility of attachmentVSAvoidstability of rocking motion
Core Design Contradiction:
Adaptability or versatilityVSReliability

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.

Inventive Principle:
Principle #15Dynamics

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

Engineering Contradiction:
Improvemobility of deviceVSAvoidspace occupied by device
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

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.

Inventive Principle:
Principle #2Taking out (Extraction)

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Engineering Contradiction:
Improveadjustability of rocking motionVSAvoidcomplexity of drive unit control
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #19Periodic action
