Incubator Side Pane Vertical Actuation for Noise and Contamination Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing incubators and open patient care units face issues with side flaps that can be contaminated, noisy, and disruptive due to gravity-induced movement, and interfere with visibility and therapy devices, while manual solutions are cumbersome and lack safety features.
Innovation Solution
The implementation of automatically moving side panes up or down on a vertical line, driven by motors or manual mechanisms, with integrated sensors and a locking mechanism for safe and controlled operation, ensuring minimal disruption and easy access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If side flaps are folded down manually, then accessibility to the patient is improved, but the inner sides of the side flaps become contaminated and microorganisms may reach the patient
Solution Approach 1:
The side flaps are extracted from the manual operation zone and placed under automatic control. The system detects when a care provider approaches and automatically opens the side flaps, then automatically closes them after a predetermined time, removing the flaps from the contaminated zone during manual handling.
Solution Approach 2:
The side flaps perform self-service by automatically opening and closing without manual intervention. The control unit monitors the situation and autonomously manages the side flap positions, eliminating the need for care providers to manually handle the flaps and preventing contamination.
2Ease of operation
If side flaps are pulled downward by gravity, then closing is simplified, but noise and vibrations are generated that affect the patient
Solution Approach 1:
The gravity-based mechanical closing system is replaced with an automated control system. The control unit receives signals from sensors (motion sensors, weight sensors) and actively controls the side flap closing mechanism, replacing passive gravitational action with active, controlled movement that eliminates noise and vibrations.
Solution Approach 2:
The system incorporates feedback through sensors that detect the position and movement of side flaps. The control unit uses this feedback information to control the closing mechanism, ensuring smooth, quiet operation and preventing the noisy, vibrating movements caused by gravity-driven collapse.
3Ease of operation
If side flaps are pivoted upward about a horizontal axis, then closing is achieved, but the side flaps interfere with the visible area and therapy devices
Solution Approach 1:
The side flaps transition from horizontal pivoting (which interferes with visibility) to vertical movement along guide rails. This dimensional change allows the side flaps to open and close without obstructing the visible area or therapy devices, as they move parallel to the front surface rather than pivoting horizontally.
Solution Approach 2:
The side flaps are segmented from the traditional hinged structure and moved independently along vertical guide rails. This segmentation allows each side flap to move vertically without interfering with the horizontal workspace or visible area, resolving the spatial conflict.
4Object-generated harmful factors
If automatic opening and closing is implemented, then noise and contamination are reduced, but device complexity increases
Solution Approach 1:
The control unit serves multiple functions: it processes signals from various sensors (motion sensors, weight sensors), controls the side flap actuation, and manages the timing of opening and closing operations. This multi-functionality consolidates complexity into a single integrated system rather than requiring separate control mechanisms for each function.
Solution Approach 2:
The control unit acts as an intermediary between the sensors and the side flap actuation mechanism. It receives input from multiple sensor types, processes the information, and translates it into appropriate actuator commands, simplifying the overall system architecture by centralizing the control logic.

AI summary
An incubator or open patient care unit (1) is provided, which can be opened and closed by one or more side panes (2). The side pane (2) or each side pane (2) is equipped with essentially vertical guide elements (3, 4). A drive (10) may be provided with an associated analysis unit (11) for the drive (10), wherein the analysis unit (11) receives sensor and/or switching signals, so that the side pane (2) can be automatically opened and/or closed by a preset time or sensor signal.
