Direct Swing Leaf Actuator Height Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing direct swing leaf actuators require precise alignment and installation to ensure proper rotational engagement between the driven shaft and the swing leaf, which can be challenging due to floor unevenness and the need for precise planning and design.
Innovation Solution
The direct swing leaf actuator incorporates an adjusting frame with a height-adjusting unit that allows for movable adjustment of the driven shaft relative to the receiving box, enabling secure rotational engagement with the swing leaf even after assembly, and allowing for fine adjustments and replacement of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driven shaft is precisely aligned with the swing leaf during assembly, then rotational engagement is secure, but the actuator cannot be adjusted after assembly and requires complete disassembly for any adjustments
Solution Approach 1:
The actuator is divided into separable modules: the actuator unit, the receiving box, and the adjusting device. This segmentation allows the adjusting device to be independently adjusted or replaced without disassembling the entire actuator or the swing leaf connection, resolving the contradiction between secure engagement and adjustability.
Solution Approach 2:
The adjusting device provides dynamic adjustability of the driven shaft position after assembly. The driven shaft can be finely adjusted in position while maintaining secure rotational engagement with the swing leaf, allowing post-assembly adjustments without complete disassembly.
2Measurement precision
If the entire actuator unit is moved for fine adjustment of the driven shaft, then alignment can be corrected, but the adjustment process becomes complex and time-consuming
Solution Approach 1:
The adjusting device is extracted as a separate functional component from the actuator unit. This allows the adjusting device to be independently adjusted to fine-tune the driven shaft position without moving or disassembling the entire actuator unit, simplifying the adjustment process while maintaining alignment precision.
3Stability of the object's composition
If the driven shaft bearing is fixed after swing leaf placement, then the structure is stable, but vertical and planar position adjustments become impossible
Solution Approach 1:
The adjusting device introduces dynamic adjustability to the driven shaft bearing position. The bearing can be adjusted in vertical and planar positions while maintaining structural stability during operation, allowing adaptation to different installation conditions without compromising stability.

AI summary
A direct swing leaf actuator for actuating a swing leaf of a door includes a receiving box for arrangement in or on a stationary part of the leaf system or of a building having the leaf system, and includes a driven shaft, which interacts with an actuator unit, wherein a swing leaf can be placed on the driven shaft in a torque-transmitting manner. A device is present for adjusting the spatial position of the driven shaft relative to the receiving box. The device has an adjusting frame with a height-adjusting unit, wherein the adjusting frame is arranged in the receiving box and the driven shaft is received on the adjusting frame so as to be height-adjustable using the height-adjusting unit.
