Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door actuation systems face design constraints and risk of damage due to exposed connecting means, which complicate assembly and reduce long-term stability.
Innovation Solution
A device with a drive and lever kinematics that includes a rotation compensation mechanism for the connecting means, allowing it to bend without rotating, compressing, or stretching, thereby reducing mechanical load and protecting it from environmental and mechanical influences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If connecting means are routed along the outside between the door leaf and the door frame, then assembly is simple and accessible, but the connecting means are exposed to damage and environmental influences
Solution Approach 1:
The connecting means is nested within the rotation space formed by the lever kinematics and drive, running through the apex point. This nesting protects the connecting means from external environmental influences and mechanical damage while maintaining functional connectivity between the door leaf and door frame.
Solution Approach 2:
The connecting means is routed through a third dimension (the rotation space apex) rather than along the traditional external path. By passing through the apex point in the rotational movement plane, the connecting means achieves a protected position that decouples it from relative rotations between components.
2Ease of repair
If connecting means are routed externally for easy access, then maintenance is easier, but the connecting means are subject to mechanical load and environmental damage
Solution Approach 1:
The connecting means is nested within the protected rotation space of the door actuation mechanism, shielding it from environmental factors such as moisture, dust, and UV radiation while reducing mechanical stress from external sources.
Solution Approach 2:
The rotation space apex acts as an intermediary point through which the connecting means passes. This intermediary position decouples the connecting means from relative rotations between the lever kinematics and drive, reducing mechanical load while maintaining electrical connectivity.
3Stability of the object's composition
If the connecting means is fixed rigidly between components, then connection stability is high, but it cannot accommodate relative rotation between the door leaf and frame
Solution Approach 1:
The connecting means is configured to dynamically adapt to the rotational movement between the door leaf and frame by passing through the rotation space apex. This dynamic routing allows the connecting means to maintain stability while accommodating changing relative positions of connected components.
Solution Approach 2:
The connecting means utilizes the rotation space dimension to pass through the apex point, creating a geometric configuration that decouples it from relative rotations. This dimensional approach allows rigid connection stability while accommodating rotational adaptability between components.
