Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for managing the combined movement of swing shutters or motorized doors face challenges in coordinating the movement of two leaves to prevent collisions and ensure complete closure, particularly when encountering unforeseen obstacles, leading to potential system damage and operational rigidity due to reliance on single motorization and complex electronic control systems.
Innovation Solution
A method involving a master and auxiliary drive system controlled by an electronic processing unit that detects obstacles, maintains movement of one leaf while stopping the other, and initiates a reinitialization procedure to return to stable positions, using current measurement and stored travel data to manage movements and prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single motor is used to manage simultaneous movements of two leaves, then device complexity is reduced, but operating flexibility and reliability deteriorate due to mechanical dependence and rigidity
Solution Approach 1:
The system divides the motorization into two independent parts: a master motor and an auxiliary motor, each capable of independently driving a leaf. This segmentation allows each motor to operate autonomously, improving flexibility and reliability while maintaining manageable complexity through hierarchical control architecture.
Solution Approach 2:
An electronic processing unit acts as an intermediary between the two motors, coordinating their operations through wireless communication. This mediator enables flexible control strategies (sequential, simultaneous, or independent operation) while keeping the overall system complexity manageable through centralized intelligence.
2Adaptability or versatility
If separate motorization of leaves is implemented, then operating flexibility improves, but device complexity increases due to doubled drive equipment and communication management
Solution Approach 1:
The system merges the control functions of two independent motors into a unified hierarchical structure with a master motor and auxiliary motor. The master motor's electronic processing unit assumes control responsibilities for both motors, reducing the need for separate control systems and simplifying communication architecture.
Solution Approach 2:
The master motor and its electronic processing unit serve multiple functions: driving the master leaf, controlling the auxiliary motor, managing obstacle detection, and coordinating overall system operation. This multi-functionality reduces the need for dedicated components for each function, thereby reducing overall complexity.
3Manufacturing precision
If complex electronic control systems with multiple units are used, then coordination precision improves, but system reliability deteriorates due to communication links and potential failures
Solution Approach 1:
The system extracts and eliminates unnecessary communication links by having the master electronic processing unit directly control both motors without requiring complex inter-motor communication. This reduces the number of potential failure points while maintaining precise coordination through centralized control.
Solution Approach 2:
The system implements feedback mechanisms where the master electronic processing unit continuously monitors the position and status of both leaves, automatically adjusting control signals to maintain precise coordination. This feedback loop ensures accurate operation while simplifying the control architecture through intelligent regulation.
4Productivity
If automated movement management is implemented, then productivity improves, but reliability deteriorates when obstacles are encountered due to inability to detect and respond to abnormal conditions
Solution Approach 1:
The system incorporates obstacle detection feedback mechanisms that monitor motor current, movement resistance, and position deviations. When an obstacle is detected, the electronic processing unit automatically responds by stopping the affected motor and coordinating appropriate actions for the other motor, maintaining both productivity and reliability.
Solution Approach 2:
The control system dynamically adapts its behavior based on real-time conditions: under normal conditions it operates in automated mode for high productivity, while upon detecting obstacles it transitions to a responsive mode that prioritizes safety and reliability, demonstrating dynamic adjustment of operational characteristics.

AI summary
The invention relates to a method for managing the encounter of unforeseen obstacles during the combined movement of two leaves which includes: - detection of an obstacle which stops the movement of one of the two leaves; - if the movement of the leaves is in the direction of opening or closing, not stopping the command for the complete opening or closing of the unstopped leaf; - detection of the arrival at the stop of said leaf; - sending a signal for the complete closing or opening of both leaves; and - command to initiate a normal opening or closing cycle.
