Drive Motor End Position Programming via Automatic Learning Cycle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drive systems for blackout devices, such as roller shutters, face challenges in accurately determining control end positions due to settling phenomena, leading to 'floating' programmed positions and the need for time-consuming reprogramming.
Innovation Solution
An automatic learning cycle is implemented during installation, where the closure element is adjusted into end stops to complete settling, with tightening in the opening direction and unwinding in the closing direction, allowing for precise programming of end positions without user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If end positions are programmed immediately after installation, then programming time is reduced, but settling phenomena cause end positions to float and require reprogramming
Solution Approach 1:
The system performs a preliminary tightening action by detecting when the closure element is adjusted into the opening end stop, which completes a large part of the settling phenomena before end position programming begins. This preliminary action ensures that subsequent end position measurements are stable and accurate.
Solution Approach 2:
The detection means monitors the position of the closure element and provides feedback to the controller. When the closure element reaches the opening end stop, the system automatically detects this state and triggers the learning cycle, ensuring that end positions are only programmed after settling has occurred.
2Measurement precision
If the closure element is tightened before programming, then settling phenomena are reduced and end position accuracy is improved, but additional time is required for the tightening process
Solution Approach 1:
The system automatically performs the tightening action and detects when it is complete without requiring manual intervention. The detection means monitors the closure element position and automatically triggers the learning cycle, making the process self-service and eliminating the need for separate manual tightening steps.
Solution Approach 2:
The tightening process and end position programming are merged into a single automated learning cycle. The system combines the preliminary tightening action with the subsequent end position measurement in one continuous process, eliminating the need for separate operations.
3Adaptability or versatility
If manual adjustment is required for end position programming, then flexibility is maintained, but automation and ease of operation are reduced
Solution Approach 1:
The system automatically performs the entire end position programming process without requiring manual intervention. The detection means monitors the closure element position and the controller automatically executes the learning cycle, making the system self-sufficient and eliminating the need for user input during programming.
Solution Approach 2:
The system uses feedback from the detection means to automatically determine when the closure element has reached the appropriate position for programming. This feedback mechanism enables the system to autonomously complete the programming process while maintaining the flexibility to adapt to different installation scenarios.

AI summary
The drive (1) has a controller (5) attached to a drive motor (4). A closure element (2) e.g. roller shutter, sunblind, window shutter, awning, sliding gate and roller blind, is motorically adjustable between open- and closed positions (6, 7) during normal operation in an operating mode of the controller. An automatic programming cycle is provided for the closed- and open positions in an installation mode of the controller and activated or released by detection of user-controlled motoric adjustment of the closure element in the open position with corresponding tightening of the element.
