Resilient Water Tank Push Button for Easy Ventilator Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ventilation therapy devices face difficulties in the convenient mounting and detachment of water tanks, which are used for humidifying respiratory gas, due to inconvenient mechanisms.
Innovation Solution
A press button with a resilient structure is integrated into the water tank, allowing it to be pressed towards the tank housing to mount or detach from the main unit, utilizing elastic deformation to facilitate easy connection and disconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional mounting mechanism is used for the water tank, then the connection is stable, but the mounting and detachment process becomes complex and inconvenient
Solution Approach 1:
The mounting mechanism is segmented into a press button component and a corresponding pressing receptacle on the main body. The press button is integrated into the water tank as a separate operable element, allowing independent actuation for mounting/detachment operations while keeping the overall structure simple
Solution Approach 2:
The press button is designed with resilient properties, allowing it to dynamically change state between pressed and unpressed positions. This dynamic characteristic enables the button to automatically return to its original position after actuation, providing a simple yet effective mounting/detachment mechanism without complex control systems
2Ease of operation
If the water tank is made detachable for easy removal, then the ease of operation improves, but the stability during connection may be compromised
Solution Approach 1:
The press button is integrated directly into the water tank structure, making the mounting/detachment operation self-contained within the water tank assembly. The button's resilient nature allows it to self-return to its original position, providing automatic reset functionality without requiring external mechanisms
Solution Approach 2:
The press button is nested within the water tank housing structure, with the button's pressing trajectory confined within the tank's internal space. The corresponding pressing receptacle is nested on the main body, creating a compact integrated mounting mechanism that maintains connection stability while enabling easy detachment
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
The press button enables a stable and flexible connection process, reducing operation difficulty and ensuring the water tank remains stable during detachment, enhancing the ease of mounting and detachment.
Implementation Method 1
the resilient structure being configured such that: when the press button is pressed toward the interior of the water tank housing, the free end moves from a first position to a second position, and the resilient structure elastically deforms

AI summary
Embodiments of this specification provide a press button for mounting and detachment of a water tank from a main unit of a ventilation therapy device. The press button is arranged on the water tank, and is configured to be pressed toward the interior of a water tank housing of the water tank under the action of an external force such that the water tank is mounted to or detached from the main unit. The press button includes a pressing body, the pressing body including a resilient structure, the resilient structure including a fixed end and a free end arranged opposite each other, and the resilient structure being configured such that: when the press button is pressed toward the interior of the water tank housing, the free end moves from a first position to a second position, and the resilient structure elastically deforms; and after the external force is released, the free end moves from the second position to the first position, and the resilient structure restores its shape to drive the press button to resiliently return to its original position away from the interior of the water tank housing such that the water tank is connected to the main unit or returns to its original position after detachment. The embodiments of this specification further provide a water tank including a press button, and a ventilation therapy device including the above water tank.
