Solution Overview
Problem
Existing passage barriers lack a simple and flexible adjustment mechanism for the pivoting range of the barrier element, which is both cost-effective and easy to manufacture.
Innovation Solution
A passage barrier design featuring guiding elements with a drive unit and a hollow shaft, where the drive unit is operatively connected to a blocking element, allowing for easy locking and unlocking via a torque transmission toothing system with a stop disk and stop lug mechanism, enabling flexible adjustment of the barrier's opening width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional locking mechanism is used for the passage barrier, then the structure is simple, but the adjustment of pivoting range is inflexible and requires complex mechanisms
Solution Approach 1:
The patent applies the dynamics principle by making the stop disk rotatable relative to the hollow shaft, allowing the stop lug to engage with different positions on the hollow shaft's outer lateral surface. This dynamic adjustment mechanism enables flexible pivoting range regulation without requiring complex locking mechanisms, as the stop disk can be easily rotated to different angular positions and locked in place using the existing torque transmission toothing.
2Adaptability or versatility
If a complex adjustment mechanism is used for the pivoting range, then the adaptability is improved, but the manufacturing cost and difficulty increase
Solution Approach 1:
The patent applies the universality principle by designing the stop disk and stop lug mechanism to serve multiple functions: it acts as both a locking mechanism and an adjustment mechanism for the pivoting range. The torque transmission toothing on the hollow shaft serves dual purposes for both driving the blocking element and locking the stop disk at different positions. This multi-functionality eliminates the need for separate adjustment mechanisms, reducing manufacturing complexity and cost.
Solution Approach 2:
The patent applies the nested doll principle by placing the stop disk inside the hollow shaft, with the stop lug engaging the outer lateral surface of the hollow shaft. The locking device is nested within the stop disk mechanism. This nested arrangement compactly integrates multiple functions within the existing structural space, avoiding additional external components and simplifying manufacturing.
3Productivity
If the blocking element is moved quickly, then the productivity is improved, but the risk of damage from torque peaks increases
Solution Approach 1:
The patent applies the beforehand cushioning principle by designing the torque transmission toothing engagement between the hollow shaft and locking device to gradually transmit torque during the movement of the blocking element. The interlocking toothing profiles are designed to distribute torque transmission over an extended engagement period, cushioning against sudden torque peaks that could cause damage, while still allowing relatively quick movement of the blocking element.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design provides a cost-effective and easy-to-produce passage barrier with a simple and flexible mechanical rotation lock, allowing for efficient regulation of pedestrian flow while reducing mechanical stress and the risk of damage from torque peaks.
Implementation Method 1
The locking device has a torque transmission toothing which engages in a complementary torque absorption toothing of the hollow shaft
Implementation Method 2
the stop disk has a stop lug formed on its peripheral surface of the stop disk, which protrudes radially from the peripheral surface of the stop disk and interacts with a stop element arranged on the vertically running profile in such a way that rotation of the stop disk by the stop of the stop lug counteracts the stop element is limited

AI summary
The invention relates to a passage barrier, the passage barrier (1) comprising guiding elements (2a, 2b). The guiding elements (2a, 2b) comprise a first guiding element (2a) and a second guiding element (2b). The first guiding element (2a) and the second guiding element (2b) cooperate in such a way that the first and second guiding elements define a lock region (3), through which people pass from an access region (4) into a passage region (5). At least one guiding element (2a, 2b) comprises a profiled element (39) running vertically, on which a locking device (19) is arranged. The locking device (19) comprises torque-transmitting teeth (35), which mesh with complementary torque-receiving teeth (15) of the hollow shaft (10). Furthermore, a circular stop disk (56) is also provided, which has a tooth engagement element (57), which engages with the torque-transmitting teeth (35) of the locking device (19). A stop protrusion (58) is formed on the stop disk peripheral surface (59) of the stop disk (56), which stop protrusion radially protrudes from the stop disk peripheral surface (59) and cooperates with a stop element (32) arranged on the profiled element (39) running vertically in such a way that rotation of the stop disk (56) is limited by the stopping of the stop protrusion (58) against the stop element (32).
