Motorized Drive Display with LED Status Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of motorized window and door drives are often unaware of the actual opening state and status of the sash due to a lack of clear indication.
Innovation Solution
A drive system comprising a motorized unit, electronic control unit, measuring device, and display device with light-emitting diodes that illuminates a field of view based on the opening state and additional information, allowing users to quickly and reliably determine the status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a motorized drive unit is installed to enable automatic operation of the sash, then convenience is improved, but the user remains unclear about the actual opening state and drive status
Solution Approach 1:
The display device uses different colors of light sources to indicate different states of the sash and drive. For example, green light indicates the sash is closed, yellow indicates partially open, and red indicates fully open or fault conditions. This color-coding system provides immediate visual feedback about the opening state without requiring complex displays.
Solution Approach 2:
The display device acts as an intermediary between the motorized drive unit and the user. It receives status information from the drive and translates it into visual signals that are easily understood by the user, bridging the information gap created by the automated system.
2Device complexity
If traditional display methods are used, then device complexity is minimized, but the user cannot quickly and reliably obtain an overview of the opening state
Solution Approach 1:
The display device segments the viewing area into multiple zones with light sources arranged in specific patterns. Different segments can be illuminated independently to indicate different states, allowing the user to quickly identify the current state without processing complex information.
Solution Approach 2:
The light sources can be activated in periodic sequences or patterns that correspond to different states. The rhythmic lighting patterns provide clear temporal and spatial cues about the sash state, making it easier to interpret at a glance.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to easily and accurately assess the opening state and status of the sash, as well as additional information like room conditions, through controlled lighting patterns and colors.
Implementation Method 1
The display device comprises a plurality of light sources, in particular light-emitting diodes (LEDs), which can be controlled via the electronic control unit such that a field of view of the display device can be illuminated in different areas and/or with different colors

AI summary
A drive for a window, door, or similar sash comprises a housing, a motorized drive unit, an electronic control unit, a measuring device connected to the electronic control unit for detecting the sash's opening state, and a display device controllable via the electronic control unit for indicating the sash's opening state and preferably at least one additional piece of information. The display device includes a plurality of light sources, in particular LEDs, which can be controlled via the electronic control unit such that a field of view of the display device can be illuminated in different areas and/or with different colors depending on the sash's opening state and, optionally, the at least one additional piece of information.
