Motorized Leaf Coordination via Learning Cycle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for managing the combined movement of motorized window or door leaves struggle with ensuring accurate role identification and coordination between leaves without relying on bilateral communication, often leading to potential collisions due to differing movement paths and dependency on radio link reliability.
Innovation Solution
A method involving independent drive devices with a parameter setting process that learns the respective roles of each leaf through a learning cycle initiated by specific signals and manual positioning, utilizing Hall effect sensors and radio frequency communication to synchronize movements without direct communication between modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If identical activation modules are used for both leaves to reduce cost, then manufacturing cost is reduced, but the system cannot distinguish between covering and covered leaves leading to potential collisions
Solution Approach 1:
The system performs preliminary positioning of leaves during a learning phase before normal operation begins. The electronic control unit stores the positions of both leaves and uses this pre-acquired information to automatically coordinate movements, preventing collisions without requiring different hardware modules for each leaf.
Solution Approach 2:
The electronic control unit receives feedback from both activation modules about their respective leaf positions and continuously adjusts control signals to coordinate movements. This feedback mechanism allows the system to distinguish between covering and covered leaves through software logic rather than hardware differentiation.
2Reliability
If bilateral communication between leaves is implemented to ensure correct operation, then coordination reliability is improved, but system complexity and dependency on radio link reliability increase
Solution Approach 1:
A central electronic control unit acts as an intermediary between the two activation modules. Instead of requiring direct communication between leaves, the control unit receives position information from both modules and coordinates their movements, simplifying the communication architecture to a centralised control model.
3Device complexity
If a single motor manages simultaneous movements of two leaves, then device complexity is reduced, but positioning accuracy decreases due to dependency on the other leaf's placement
Solution Approach 1:
The system uses two independent activation modules instead of a single motor, allowing each leaf to be controlled separately. This segmentation enables independent positioning of each leaf while the electronic control unit coordinates their movements to prevent collisions, achieving both simplicity and precision.

AI summary
The present invention relates to a method for configuring a system that manages the combined movement of two motorized leaves of hinged shutters or motorized doors, in order to teach them their respective roles as a covered leaf and a covering leaf. They are activated by a remote control between two stable open and closed positions for clearing and closing door or window openings, each leaf being connected via an arm to a module comprising drive means and an electronic control unit equipped with a radio frequency signal transmitter/receiver.According to the procedure: - activation of each module by communication of a first signal; - acknowledgment of the reception of the first signal by the activation module; - manual positioning of the leaves in a predefined preferential position depending on their role as a covering or covered leaf, and connection of the leaves to the modules by the arms in this preferential position; - communication to each module of a second trigger signal of the beginning of the parameterization phase; - triggering, by means of the remote control, of a learning cycle commanding the drive means to control a combined opening and closing of the leaves in the role which has been assigned to them.
