Egg Drawing Toy Adjustable Support Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing egg-drawing toys have poor stability and are limited in their ability to accommodate eggs of different sizes due to fixed support structures, leading to unstable rotation and compatibility issues with various egg types.
Innovation Solution
An egg-drawing toy with an adjustable support spacing featuring a vertical design, elastic supports, and a motor-driven rotating shaft with adjustable positioning, allowing for secure fixation and rotation of eggs of varying sizes through a torsion spring and compression spring mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If horizontal egg-drawing toys with fixed support wheels are used, then the structure is simple, but the stability is poor and rotation effects are inconsistent
Solution Approach 1:
The patent implements adjustable support spacing that can be dynamically modified to accommodate different egg sizes. The support distance adjustment mechanism allows the device to adapt its configuration, transforming from a static fixed-structure to a dynamic adjustable-structure, thereby improving stability while maintaining reasonable complexity
Solution Approach 2:
The patent changes the key parameter of support distance between upper and lower supports. By allowing this parameter to be adjusted rather than fixed, the device can optimize its stability for different egg dimensions, resolving the contradiction between simple structure and stable performance
2Device complexity
If fixed support spacing is used, then the structure is simple, but the adaptability to different egg sizes is poor
Solution Approach 1:
The adjustable support spacing mechanism enables the device to dynamically adapt to different egg sizes by modifying the distance between supports, transforming a static simple structure into a dynamic adaptable system
Solution Approach 2:
The patent designs the egg-drawing toy with universal adaptability to accommodate various egg sizes through adjustable support spacing, allowing one device to serve multiple functions for different egg dimensions without requiring multiple specialized devices
3Strength
If screw connection bosses are required on toy eggs, then the connection is secure, but the limitations and device complexity increase
Solution Approach 1:
The patent employs a universal magnetic connection mechanism that can securely attach to various toy egg types without requiring specific screw connection bosses. This magnetic attachment system provides both secure connection strength and broad compatibility, eliminating the need for egg-specific mounting features
Solution Approach 2:
The patent replaces the mechanical screw connection system with a magnetic field-based attachment system. This substitution eliminates the need for physical screw bosses on eggs while maintaining secure connection, thereby improving versatility without sacrificing connection strength
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 vertical structure with adjustable supports ensures stability and universality, enabling secure rotation and drawing of eggs of different sizes, enhancing the toy's usability and aesthetic appeal.
Implementation Method 1
a compression spring for supporting the input gear is sleeved outside the guidepost
Implementation Method 2
the shell and the cover are rotationally connected and elastically reset by the action of a torsion spring and a bolt

AI summary
An egg-drawing toy with an adjustable support spacing, which adopts a vertical structure with two supports, is stable in support, and is suitable for fixing eggs or toy eggs. In addition, the lower support is designed to have an elastic support structure, and the spacing between the upper support and the lower support is adjustable, which is automatically achieved by a compression spring, thereby realizing the support and positioning of eggs with different sizes between the upper support and the lower support, and thus having better universality.
