Magnetic Platform Doll with Single Motor Animation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing animated dolls either require permanent mounting on a platform for animation or lack sophisticated mechanisms for lifelike motion and power distribution, limiting their versatility and realism.
Innovation Solution
The development of electrically powered dolls that removably stand on a platform by magnetic attraction, utilizing a single animation motor for head, body, and arm movements, with proportional feedback control, and featuring rotatable legs and a rotating platform for dynamic motion, allowing for removable play and varied animation scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the doll is permanently mounted on the platform for animation, then the animation mechanism can operate reliably, but the doll loses versatility for removable play
Solution Approach 1:
The doll is divided into separable components: a doll body with magnetic feet and a platform with corresponding magnetic bases. This segmentation allows the doll to be permanently mounted on the platform for reliable animation operation while enabling easy removal for versatile play scenarios, resolving the contradiction between reliability and adaptability.
Solution Approach 2:
The magnetic attachment mechanism provides dynamic binding strength that can be adjusted. When the doll is placed on the platform, magnetic attraction securely holds it in position for reliable animation. When removal is needed, the magnetic force can be overcome to allow easy detachment, providing both reliability during operation and versatility for play.
2Ease of manufacture
If multiple motors are used for head, body, and arm movements, then lifelike motion is achieved, but the device complexity and power requirements increase
Solution Approach 1:
Multiple animation functions (head movement, body movement, arm movement) are merged into a single motor system. The motor drives a mechanism that can animate multiple body parts simultaneously or sequentially, achieving lifelike motion without the complexity of multiple separate motors and their associated power requirements.
Solution Approach 2:
The single motor is designed with universal capability to drive different animation sequences and body part movements. Through control mechanisms, the same motor can produce various motion patterns for head, body, and arms, making the system multi-functional while reducing overall device complexity.
3Adaptability or versatility
If the doll contains internal power sources and animation mechanisms, then it can operate independently, but the doll size and portability are reduced
Solution Approach 1:
The power source and main animation motor are extracted from the doll body and placed in the external platform. The doll retains only minimal components for receiving power and executing simple animations. This extraction allows the doll to remain compact and portable while still achieving independent operation through the external power system.
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
Enables lifelike motion and animation of dolls with removable platform interaction, providing enhanced realism and versatility in play, while maintaining compactness due to external power sourcing from the platform.
Implementation Method 1
The doll is removable from the platform for other play by physically overcoming the magnetic attraction of the doll's feet to the platform on which it may be standing
Implementation Method 2
electrically powered dolls that removably stand on a platform by magnetic attraction, utilizing a single animation motor for head, body, and arm movements

AI summary
Pose and play dolls that will stand on a platform by magnetic attraction and dance with lifelike animation, but which may be removed from the stand for ordinary play. The dolls include animation powered from the platform through the legs of the doll. A motor in the doll animates the doll body, arms and head, with proportional feedback allowing control by a controller in coordination with music being played. The doll head may rotate or gyrate, and the arms swing as a unit or with the lower arms bending as the arms swing. In one form of platform simply rotates through controlled angles, again in coordination with the music being played. In another form of doll, the hips are configured to swing back and forth, and another form of platform controls the hip movement, again in coordination with the music being played. Various other features and capabilities are disclosed.
