Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a worm and worm gear rotating arm is used, then the structure is simpler than electrically controlled linkage mechanisms, but the meshing gap causes the rotating arm to shake and the output torque is limited
Solution Approach 1:
The locking mechanism is divided into two independent parts: a locking drive apparatus that drives the first rotating member, and a second locking mechanism that cooperates with the second rotating member. This segmentation allows each component to perform its specific function optimally without interfering with the other, resolving the contradiction between structural simplicity and operational stability.
Solution Approach 2:
The patent introduces a third rotating member as an intermediary element that cooperates with the first rotating member to drive the second rotating arm to rotate. This intermediary component ensures stable power transmission and docking between rotating arms, eliminating the shaking problem caused by direct worm-worm gear meshing gaps.
2Extent of automation
If an electrically controlled linkage mechanism is used, then the locking operation is automated, but the structure becomes complex, bulky, and the motor power output is unstable
Solution Approach 1:
The patent extracts the essential locking function from a complex electrically controlled linkage mechanism and implements it through a simplified mechanical system. The locking drive apparatus and dual locking mechanisms work together to achieve automated locking without requiring complex linkages, bulky components, or unstable motor power outputs.
Solution Approach 2:
The patent replaces complex electrically controlled linkage mechanisms with a more efficient mechanical system based on worm-screw and nut mechanisms. This substitution maintains automation while reducing structural complexity, eliminating bulky components, and providing more stable power output through pure mechanical advantage.
3Device complexity
If manual operation is used for locking, then the structure can be simpler, but the operation is inefficient and time-consuming
Solution Approach 1:
The locking mechanism is designed to be self-operating through the cooperation of the locking drive apparatus and dual locking mechanisms. The system automatically performs locking and unlocking operations without requiring manual intervention, achieving both structural simplicity and operational efficiency simultaneously.

AI summary
In the present invention, through the cooperation of the first rotating member provided in the first rotating arm and the third rotating member provided in the second rotating arm, the port docking of the first rotating arm and the second rotating arm are achieved. Then, the second rotating member of the first rotating arm cooperates with the second locking mechanism in the second rotating arm to perform the locking action. As the locking process of the rotating arm is divided into two steps of docking and locking, which are executed by corresponding structures, the locking stability between the locking arms and the unlocking flexibility can be ensured.
