Infant Incubator Door Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing infant incubators, the end-side treatment door is not effectively locked in the closed state, and there is a risk of it being opened or closed improperly, which can disrupt the environmental conditions within the infant chamber.
Innovation Solution
The infant incubator incorporates a door-locking device that uses an open-close knob with a hook end and a knob bracket to lock the left and right-side treatment doors with the end-side treatment door, ensuring it remains closed, and a canopy gasket with a vertical-wall portion and protruded ridge to maintain sealing and prevent improper opening or closing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the end-side treatment door is made independently operable, then medical treatments can be performed from any side, but the door may be opened or closed carelessly disrupting the enclosed environment
Solution Approach 1:
The door-locking device merges the control of the end-side treatment door with the left and right-side treatment doors. When the side doors are closed, the locking device automatically engages to secure the end door, ensuring environmental integrity while preserving independent operability for treatment access.
Solution Approach 2:
The locking device acts as an intermediary mechanism between the treatment doors and the enclosed environment. It mediates between the need for door operability and the need for environmental stability by engaging only when side doors are closed, thus preventing careless opening while allowing controlled access.
2Reliability
If a locking device is added to secure the end-side treatment door, then the door can be locked reliably, but the device complexity increases
Solution Approach 1:
The door-locking device is designed to operate automatically based on the state of the left and right-side treatment doors. When the side doors are closed, the locking mechanism engages automatically without requiring separate manual operation, thereby providing reliable locking while minimizing operational complexity.
Solution Approach 2:
The locking function is extracted as a separate, dedicated device that operates independently from the door opening/closing mechanism. This modular approach allows the locking function to be implemented with simple mechanical components (knob and bracket) rather than integrating it into a complex unified system.
3Reliability
If the canopy and end-side treatment door are tightly sealed, then the enclosed environment is maintained, but the door becomes difficult to open
Solution Approach 1:
The gasket is pre-compressed between the canopy and the end-side treatment door to create the seal. This preliminary compression action maintains the sealed environment during operation, while the locking device ensures the door remains securely positioned without requiring excessive force for opening.
Solution Approach 2:
A flexible gasket material is used to create the seal between the canopy and the end-side treatment door. The flexibility of the gasket allows it to conform to slight variations in surface geometry, maintaining effective sealing while accommodating the natural movement and positioning of the door during opening and closing operations.

AI summary
An infant incubator including: a left-side treatment door, a right-side treatment door, and an end-side treatment door which are rotatably held, and door-locking devices which fixes the left-side and right-side treatment doors on the end-side treatment door; the door-locking devices are formed from: open-close knobs each mounted rotatably on the left-side and right-side treatment doors and each having a hook-shaped distal end, and knob brackets each mounted on side of the end-side treatment doors having a hollow-shape, the infant incubator in which the treatment doors are fixed in a stand state by inserting the open-close knob into the knob bracket.
