Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing toys with the same size as the toy model are unable to act, pose in different shapes, or make different postures independently, lacking fun and a sense of technology, and lack the ability to interact with the user, lacking fun and a sense of technology.
Innovation Solution
A mechanical transmission device base that supports installation, playing, replacement, and disassembly of various toy models, driving internal mechanisms to act independently through servo motion, enabling actions such as turning head, turning waist, raising hands, blinking, and posing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manually bending joints is used to operate toys, then the toy can be operated, but the toy cannot act, pose in different shapes, or make different postures independently
Solution Approach 1:
The transmission device is divided into multiple independent transmission units, each corresponding to a joint of the toy model. Each transmission unit includes a transmission rod, connecting rod, and limiting assembly that can independently control the motion of its associated joint, enabling the toy to perform multiple actions simultaneously
Solution Approach 2:
The base is designed with a universal interface that can accommodate different types of toy models (animals, characters, vehicles) through standardized connection structures. The same base with multiple transmission units can control various toy models to perform different actions, making the system multi-functional and adaptable
2Adaptability or versatility
If a fixed transmission rod is used, then the structure is simple, but the toy model cannot be replaced with different types
Solution Approach 1:
The connection between the base and toy model uses a quick-dismantling assembly with movable components including a T-shaped block that can slide within a T-shaped groove and a movable connecting rod. This dynamic connection allows the toy model to be easily attached and detached while maintaining stable fixation during operation
Solution Approach 2:
The quick-dismantling assembly uses a nested structure where the T-shaped block fits within the T-shaped groove, and the movable connecting rod connects to both the base and toy model. This nested design allows for compact assembly and easy disassembly while maintaining structural integrity
3Ease of operation
If limited motion control is used, then the device is simple, but the toy model cannot perform multiple actions independently
Solution Approach 1:
The motion control system is segmented into multiple independent transmission units, each responsible for controlling a specific joint or body part of the toy model. Each unit includes its own transmission rod, connecting rod, and limiting assembly, allowing precise independent control of each body part's motion
Solution Approach 2:
The limiting assembly acts as an intermediary mechanism between the transmission rod and the toy model joint. It includes a limiting block that can slide along the transmission rod and a limiting arm that connects to the joint, providing precise control and limitation of the joint's motion range while transmitting force efficiently

AI summary
A mechanical transmission device base used for replaceable toy model is provided, where a toy model is placed on the base, the base includes an upper shell assembly and a lower shell assembly, a pair of quick-dismantling assemblies, a servo assembly, and a PCB of base are set between the upper shell assembly and the lower shell assembly; the toy model is set on the mechanical transmission device base by male snaps of the quick-dismantling assemblies. When the toy model is installed, it is locked by the male snaps to keep stable fixation on the base; top bars equipped with mushroom male snaps are set on the top of the servo assembly, male snaps are matched with female snaps, so as to realize action of toy model. The mechanical transmission device base supports installation, play, replacement and disassembly of various types of toy models which match with the base.
