Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional turnstile is used, then the structure is simple, but it lacks operational modes to meet diverse user needs
Solution Approach 1:
The patent implements dynamic operational modes by enabling the barrier to switch between locked and unlocked states through electromagnetic locking mechanisms. The system can operate in multiple modes including single-direction passage, bidirectional passage, and locked states, allowing the turnstile to adapt to different user needs and access control requirements without requiring completely different device structures.
Solution Approach 2:
The turnstile device is designed with multi-functionality to serve various operational purposes. The electromagnetic locking mechanism allows the same physical structure to perform multiple functions: controlling access in single direction, allowing bidirectional passage, maintaining locked states for security, and providing automatic barrier return. This universal design meets diverse user needs while using a single integrated structure.
2Reliability
If electromagnetic locking is added for access control, then security is improved, but device complexity increases
Solution Approach 1:
The patent replaces traditional complex mechanical locking mechanisms with electromagnetic locking systems. Instead of using multiple mechanical latches, springs, and levers, the invention employs electromagnetic locks that can be controlled through electrical signals. This substitution simplifies the overall locking mechanism while improving reliability and enabling more sophisticated access control features such as timed locking, card-based authentication, and automatic barrier return.
3Object-affected harmful factors
If automatic barrier return is implemented, then user safety is improved, but additional components are required
Solution Approach 1:
The turnstile system implements self-service through automatic barrier return functionality. After a user passes through the turnstile, the system automatically returns the barrier to its initial position without requiring manual intervention. This is achieved through electromagnetic locking mechanisms that automatically engage and disengage, and through control systems that monitor user passage and trigger appropriate barrier movements. The system serves itself by automatically maintaining security and guiding users through the passage.

AI summary
A rotation device includes a base seat, an axle unit, a lower rotating module and an upper rotating module. The axle unit includes an upper axle and a lower axle. The lower rotating module includes a lock unit, and an outer barrel that is disposed in the base seat and that is penetrated by the lower axle. The lock unit includes a lock plate that is sleeved on the lower axle, and a lock member that is mounted to the base seat. The lock plate is formed with a first lock groove. The lock member has a lock portion that is operable to move into the first lock groove. The upper rotating module is disposed in the base seat and is co-rotatably sleeved on the upper axle. The upper rotating module is able to be driven by the upper axle to rotate relative to the lower rotating module.
