Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed structure is used for the parking lock, then the structure is simple and easy to manufacture, but it cannot adapt to different models and sizes of electric bicycles
Solution Approach 1:
The parking lock employs a movable rod that can shift position along the width of the mounting base, allowing the lock rod to dynamically adjust its locking position. This dynamic adjustment mechanism enables the same parking lock structure to accommodate different electric bicycle models and sizes without requiring multiple fixed designs, thereby resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The parking lock is divided into independent functional modules: a mounting base, a movable rod, and lock rods with guide posts. This segmentation allows each component to perform its specific function while maintaining overall system flexibility. The movable rod can be independently positioned, and the lock rods can be independently adjusted, enabling adaptation to various bicycle configurations without increasing overall structural complexity.
2Reliability
If a fixed locking structure is used, then the device complexity is low, but the locking security and reliability are insufficient
Solution Approach 1:
The guide post acts as an intermediary element between the movable rod and the lock rod. It guides the lock rod's movement and ensures proper alignment during locking and unlocking operations. This intermediary component enhances locking reliability by preventing misalignment and ensuring consistent engagement, while adding minimal complexity to the overall mechanism.
Solution Approach 2:
The reset spring provides automatic return functionality, causing the lock rod to automatically return to its initial position after locking or unlocking operations. This self-service mechanism ensures reliable resetting without requiring manual intervention or complex control systems, thereby improving reliability while maintaining low device complexity.
3Adaptability or versatility
If the lock rod is made movable to adjust positioning, then adaptability improves, but the device complexity increases
Solution Approach 1:
The guide post creates a guided path that allows the lock rod to move smoothly along a predetermined trajectory. This equipotential guidance ensures that the lock rod can be positioned at different locations along the guide post without requiring additional actuators or complex positioning mechanisms, thereby achieving adaptability while minimizing the increase in device complexity.
Solution Approach 2:
The patent replaces complex electronic or actuated positioning systems with a simple mechanical guide post structure. The guide post uses basic mechanical guidance principles to enable smooth movement and positioning of the lock rod, achieving adaptability through purely mechanical means rather than complex automated systems, thus limiting the increase in device complexity.

Function Achieved in This Case
The solution enhances the adaptability and intelligence of the parking lock, ensuring secure locking and efficient unlocking of electric bicycles, improving the overall functionality and user experience of the parking pile.
Implementation Method 1
There is a first reset spring on the outer surfaces of the first guide post and the second guide post. The first reset spring is held between the first base plate and the movable rod.
Implementation Method 2
The outer surface of the push rod is also equipped with a second reset spring. Both ends of the second reset spring are respectively abutted against the second side plate and the inner wall of the first lock rod shroud.

AI summary
Disclosed are an electric bicycle parking pile and a parking lock structure thereof, including a mounting base, a movable rod and at least one lock rod extending outward along the width of the mounting base. The mounting base includes a first base plate and two first side plates extending upward from two opposite sides of the first base plate. The middle of each first side plate includes a chute extending along the height. A first reset spring on the outer surfaces of the first guide post and the second guide post can enlarge the adjustment range of the lock rod and the application range of the parking lock, and make the lock rod automatically return to the initial position. The lock lever includes a locking groove. There is a preset angle of inclination between the axis of the lock lever and the first base plate.
