Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional swing gates or turnstiles are used, then passage control is achieved, but it becomes difficult for people with luggage or strollers to pass through
Solution Approach 1:
The blocking element is divided into multiple segments (first blocking element and second blocking element) that can move independently. This segmentation allows the barrier to adapt its configuration - forming a closed barrier for normal control or an open passage for accessibility needs, resolving the contradiction between control reliability and ease of passage.
Solution Approach 2:
The blocking elements are designed to be dynamically reconfigurable between different positions (blocking position and passage position). The first blocking element can rotate between blocking and passage positions, while the second blocking element can rotate between blocking and retracted positions. This dynamic capability enables the system to switch between strict control mode and accessible passage mode, simultaneously achieving both control reliability and ease of operation.
2Reliability
If complex barrier systems with multiple components are used, then passage control reliability is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple blocking functions into a unified barrier system where the first and second blocking elements work together. The drive unit integrates the driving mechanism for both elements, and the control unit coordinates their operations. This merging approach achieves reliable passage control through coordinated action of integrated components rather than separate complex systems.
Solution Approach 2:
The first blocking element serves multiple functions: it can rotate to the blocking position for normal control, rotate to the passage position for accessibility, and be driven by a universal drive unit. The second blocking element similarly provides both blocking and retraction functions. This multi-functionality reduces the need for separate specialized components, thereby reducing overall device complexity while maintaining control reliability.
3Productivity
If automated access control with sensors and motors is implemented, then productivity and access control efficiency are improved, but device complexity and cost increase
Solution Approach 1:
The control unit is configured to automatically control the drive unit based on detected passage events. The system can autonomously determine when to move blocking elements based on sensor inputs or control signals, reducing the need for complex manual intervention systems while maintaining high access control efficiency.
Solution Approach 2:
The patent employs a drive unit with friction wheels that utilize friction-based driving instead of complex mechanical gear systems. The friction wheels can drive the blocking elements through frictional contact, simplifying the mechanical transmission system while maintaining effective control. This substitution of traditional mechanical gear systems with friction-based driving reduces device complexity while preserving automated control functionality.

Implementation Method 1
the ring segment is driven by a frictional connection between its contour and the drive element, especially when the drive is realized by opposing, electric-motor-driven friction wheels, between which the contour is received and the ring segment is moved by frictional engagement
