Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drive devices for window or door assemblies are limited to a pushing motion, lacking a sequence of driven and manually operable displacement sections, restricting their functionality.
Innovation Solution
Incorporation of a switch and/or sensor system, such as a metal detector, to detect a partially open position, enabling the drive device to be activated or deactivated accordingly, allowing for efficient use and energy savings by only activating when necessary, and facilitating automated or manual displacement sequences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the drive device is continuously active to ensure smooth operation, then the displacement function is reliable, but energy consumption increases
Solution Approach 1:
The drive device operates periodically rather than continuously. The control unit activates the drive device only when displacement is required (e.g., when the sensor detects the component is not in the desired position), and deactivates it when the component is properly positioned. This periodic operation maintains reliability while significantly reducing energy consumption compared to continuous operation.
Solution Approach 2:
The system employs a sensor to detect the position of the component and provides feedback to the control unit. The control unit uses this feedback information to determine when to activate or deactivate the drive device, ensuring operation only when necessary. This feedback mechanism enables reliable position control while avoiding unnecessary energy consumption during steady states.
2Measurement precision
If the drive device is activated frequently to maintain positioning, then positioning accuracy is improved, but energy consumption increases
Solution Approach 1:
The sensor continuously monitors the component position and provides feedback to the control unit. The control unit analyzes this feedback to determine whether the component is within the acceptable position range. Only when the component deviates from the desired position does the control unit activate the drive device to correct the positioning. This feedback-based approach maintains positioning accuracy while avoiding frequent unnecessary activations that would waste energy.
Solution Approach 2:
The system uses partial action by activating the drive device only when necessary to correct positioning deviations, rather than continuously or excessively activating it. The control unit determines the exact moment when correction is needed based on sensor feedback, applying the minimum necessary action to achieve accurate positioning without energy waste from over-action.
3Ease of operation
If the drive device performs all displacement operations automatically, then operational convenience is improved, but device complexity increases
Solution Approach 1:
The system implements self-service functionality where the control unit automatically monitors the component position via the sensor and activates the drive device as needed without requiring manual intervention. The system detects when displacement is required and executes the correction automatically, providing operational convenience. The complexity is managed by using simple sensor-driven logic rather than complex control algorithms.
Solution Approach 2:
The patent replaces manual mechanical operation with an automated control system that uses electronic sensors and a control unit to manage the drive device. This substitution of mechanical manual control with electronic automation improves operational convenience. The complexity is kept manageable by using straightforward sensor-actuator control rather than complex multi-variable control systems.

AI summary
An assembly includes a drive device, a component to be displaced relative to a wall element for closing an opening of the wall element, and a guide device with which the component can be displaced relative to the wall element. A switch and/or a sensor system, preferably a metal detector, allows a partially open position of the component to be detected and/or allows the drive device to be activated, preferably based on a detection of the partially open position starting from a fully open position, and/or allows the drive device to be deactivated, preferably based on a detection of the partially open position starting from a closed position.
