Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking device is integrated into the door opener structure, then operational reliability is improved, but device complexity and difficulty of retrofitting increase
Solution Approach 1:
The locking device is divided into separate functional components: a locking body with a locking pin at one end and a pressure bolt at the other end, both independently displaceable axially. This segmentation allows each component to perform its specific function while simplifying the overall structure and enabling easy retrofitting without modifying the door opener structure.
Solution Approach 2:
The locking device is designed as a universal component that can be retrofitted onto existing door openers without structural modifications. The combination of the locking pin and pressure bolt provides multiple functions: mechanical locking, force transmission, and position holding, making it adaptable to various door configurations while maintaining operational reliability.
2Device complexity
If the locking device uses fixed components, then structural simplicity is maintained, but adaptability to different door configurations is reduced
Solution Approach 1:
Both the locking pin and pressure bolt are designed to be independently displaceable in the axial direction relative to the locking body. This dynamic design allows the components to move and adjust during operation, enabling the locking device to adapt to different door configurations and latch positions while maintaining a simple overall structure.
Solution Approach 2:
The independent axial displacement capability of the locking pin and pressure bolt allows the locking device to change its operational parameters dynamically. The locking pin can extend to engage with the latch, while the pressure bolt can be positioned to apply force at different points, providing versatility across various door types without increasing structural complexity.
3Ease of manufacture
If the locking pin is permanently fixed, then manufacturing simplicity is maintained, but ease of repair and replacement is reduced
Solution Approach 1:
The locking pin is designed as a separate, replaceable component that can be independently removed and replaced. This segmentation maintains manufacturing simplicity as each component can be produced using standard processes, while simultaneously enabling easy repair and replacement of the locking pin without replacing the entire locking device or modifying the door opener structure.

AI summary
The proposed invention relates to a locking device (1) for a door opener (2) with a door opener latch (22), wherein the locking device mechanically holds the door opener (2) in a release position after the door opener latch (22) is released until either the door opener latch (22) pivots or a lock latch (81) disengages from the locking device. To ensure flexible application and high operational reliability, it is proposed that the locking device (1) be designed in multiple parts and include a locking body (11) which axially displaces a locking pin (12) and a pressure bolt (13).
