Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional actuating mechanisms are used for the flip assembly, then the flip can be opened and closed, but the control precision is insufficient and machining complexity increases
Solution Approach 1:
The actuating assembly is segmented into distinct functional components: a driving gear integrated with the locking device, and a transmission gear separate from the flip. This segmentation allows each component to be optimized independently, improving control precision while simplifying manufacturing of individual parts.
Solution Approach 2:
The locking device and driving gear are merged into a single integrated component. This combination eliminates the need for separate locking mechanisms, reducing the number of parts and machining operations required, thereby reducing overall device complexity while maintaining precise control.
2Manufacturing precision
If traditional gear engagement structures are used, then power transmission is achieved, but alignment precision is poor and engagement is not smooth
Solution Approach 1:
The driving gear features a localized abutting portion on its outer periphery that engages with a corresponding abutting tooth on the transmission gear. This localized engagement structure concentrates the force transmission at specific points, ensuring precise alignment and smooth engagement without requiring high precision across the entire gear interface.
Solution Approach 2:
The abutting tooth on the transmission gear acts as an intermediary element between the driving gear's abutting portion and the transmission gear's main body. This intermediary structure facilitates smooth power transmission and alignment, reducing the direct mechanical stress and improving engagement quality.
3Device complexity
If the flip is left uncontrolled in the closed position, then the structure is simpler, but undesired opening occurs
Solution Approach 1:
The locking device integrates a self-locking mechanism where the driving gear's abutting portion automatically engages with the transmission gear's abutting tooth when the flip is in the closed position. This self-service locking action maintains position stability without requiring additional active control systems, keeping the structure simple while preventing undesired opening.
Solution Approach 2:
The locking device provides preliminary anti-action by pre-engaging the abutting portion and abutting tooth to prevent the flip from opening before any actuation command is given. This preventive locking mechanism ensures position stability from the outset, eliminating the need for complex continuous control systems.

Implementation Method 1
a driving gear and a transmission gear, wherein an outer periphery of the driving gear is provided with a first outer periphery portion and a second outer periphery portion, the first outer periphery portion is provided on one side of the second outer periphery portion in a circumferential direction
Implementation Method 2
when the flip is closed and the driving gear remains stationary, the abutting tooth is capable of abutting the driving gear abutting portion, thereby blocking rotation of the transmission gear in the first direction
