Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door operators often have connecting means that affect the design of the door and are prone to damage, as they are exposed and not well-protected.
Innovation Solution
A device with a twisted connecting means that is routed through a twisting section, providing rotational compensation and protection against damage, allowing for automatic actuation of a door leaf while maintaining a compact design and reducing mechanical stress on the connecting elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If connecting elements are routed externally between the door leaf and frame, then installation is simple and cost-effective, but the connecting elements are exposed to damage and detract from the door's appearance
Solution Approach 1:
The connecting element is nested within the lever kinematic mechanism, specifically routed through the lever element. This protects the connecting element from external damage while maintaining installation simplicity, as the connecting element is integrated into the existing mechanical structure rather than requiring separate external routing.
Solution Approach 2:
The lever element serves as an intermediary structure that carries and protects the connecting element. By routing the connecting element through the lever element, the mechanism provides both mechanical function and protection, eliminating the need for separate external cable routing.
2Ease of manufacture
If connecting elements are routed externally between the door leaf and frame, then installation is simple and cost-effective, but the connecting elements detract from the door's appearance
Solution Approach 1:
The connecting element is nested within the lever kinematic mechanism, specifically through the lever element. This conceals the connecting element from external view, improving aesthetic appearance while maintaining installation simplicity as the routing is integrated into the existing mechanical components.
3Reliability
If the connecting element is routed through a twisting section, then rotational compensation is achieved and mechanical stress is reduced, but the device complexity increases
Solution Approach 1:
The lever element serves multiple functions: it provides the mechanical lever arm for the kinematic mechanism and simultaneously serves as a protective conduit for the connecting element with its twisting section. This multi-functionality achieves rotational compensation without adding separate dedicated structures, thus avoiding increased device complexity.
