Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional power units or complex linkage mechanisms are used to achieve coordinated motion of multiple components, then the coordinated motion requirement is met, but product costs increase and structural flexibility decreases
Solution Approach 1:
The patent merges multiple transmission functions into a single planetary gear system. The sun gear, planetary gears, and ring gear work together as an integrated mechanism to simultaneously drive multiple execution components, eliminating the need for separate transmission structures for each component while ensuring synchronized motion.
Solution Approach 2:
The planetary gear system serves multiple functions: it provides synchronized motion to multiple execution components, achieves different speed ratios through various engagement configurations, and maintains structural compactness. This multi-functional design replaces what would traditionally require multiple specialized transmission mechanisms.
2Reliability
If additional power units are used to drive multiple components simultaneously, then coordinated motion is achieved, but manufacturing costs increase
Solution Approach 1:
The patent combines multiple driving functions into a single motor coupled with the planetary gear system. This single power unit replaces what would traditionally require multiple motors, significantly reducing manufacturing costs while maintaining the capability to synchronize multiple execution components through the gear mechanism's inherent mechanical coupling.
3Reliability
If complex linkage mechanisms are used to coordinate multiple components, then motion coordination is achieved, but structural flexibility decreases
Solution Approach 1:
The planetary gear system provides dynamic adaptability through different engagement configurations. By selectively engaging planetary gears with the sun gear or ring gear, the system can achieve different motion patterns and speed ratios, allowing the same basic structure to adapt to various coordinated motion requirements without sacrificing structural flexibility.

AI summary
A multi-stage synchronous driving mechanism and an electric toy are provided. The electric toy includes a multi-stage synchronous driving mechanism. In terms of the multi-stage synchronous driving mechanism, on one hand, by means of engagement between a sun gear and a planetary gear, all execution units are ensured to rotate synchronously based on a preset proportion, thereby greatly improving consistency and accuracy of motion among execution units. Further, torque of a motor can be transferred to the sun gear by using the gear transmission component, and a single sun gear can drive a plurality of planetary gears to rotate at the same time, so that the plurality of execution units rotate relative to a support without using a plurality of transmission structures or a plurality of transmission shafts. In this way, the present disclosure may have excellent structural flexibility and lower manufacturing costs.
