Vacuum suction device and electronic device including the same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vacuum suction devices used to stabilize electronic devices like desktop computers and Bluetooth speakers make it inconvenient to relocate them, as the suction pads are difficult to remove and can be aesthetically unpleasing when protruding.
Innovation Solution
A vacuum suction device with a suction pad having a concave inner surface and a vent hole, equipped with a valve member that closes as internal pressure decreases, allowing easy detachment by raising or rotating the device, facilitating relocation while maintaining stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a vacuum suction device is used to stabilize electronic devices, then the positioning stability is improved, but the ease of relocation deteriorates
Solution Approach 1:
The suction pad incorporates a valve member that can dynamically change its state between open and closed positions. When the device is placed on a surface, the valve closes to maintain vacuum and stabilize the device. When relocation is needed, the valve opens to release the vacuum, allowing easy removal. This dynamic state change resolves the contradiction between stable positioning and ease of relocation.
Solution Approach 2:
The suction pad uses the weight of the electronic device itself to trigger the valve closure mechanism. As the device is placed on a surface, its weight automatically causes the valve to close and maintain the vacuum state, stabilizing the device without requiring external intervention. This self-service mechanism improves both stability and ease of operation.
2Stability of the object's composition
If the suction pad is designed for strong adhesion, then the positioning stability is improved, but the ease of removal deteriorates
Solution Approach 1:
The valve member dynamically controls the vacuum state within the suction pad. During normal operation, the valve remains closed to maintain strong adhesion for stable positioning. When removal is needed, the valve opens to equalize pressure, allowing easy detachment. This dynamic control resolves the contradiction between strong adhesion and ease of removal.
Solution Approach 2:
The valve member acts as an intermediary mechanism between the internal vacuum pressure and the external environment. It mediates the contradiction by selectively allowing or blocking pressure equalization, thereby controlling the adhesion strength. When closed, it maintains strong adhesion; when open, it enables easy removal.
3Ease of operation
If the suction pad edge protrudes outward from the device, then the ease of removal is improved, but the aesthetic appearance deteriorates
Solution Approach 1:
The suction pad is nested within a recess formed in the bottom surface of the electronic device. This nesting arrangement allows the suction pad to be concealed within the device body, improving aesthetic appearance. The valve member is positioned such that it can be accessed for operation while maintaining a clean external appearance, resolving the contradiction between ease of removal and aesthetic appearance.
4Shape
If the suction pad is completely concealed within the device, then the aesthetic appearance is improved, but the ease of removal deteriorates
Solution Approach 1:
The suction pad is nested within a recess in the device bottom surface, providing a clean aesthetic appearance. The valve member is strategically positioned within this nested structure, allowing it to be accessed and operated for removal purposes while maintaining the concealed design. This nested arrangement resolves the contradiction between aesthetic appearance and ease of removal.
Solution Approach 2:
The valve member serves as an intermediary element that bridges the concealed suction pad and the user's need to remove the device. It is positioned within the recess structure, allowing users to access and operate it without compromising the aesthetic appearance of the concealed design, while still enabling easy removal when needed.
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 stable positioning of electronic devices without the hassle of direct suction pad removal, enhancing usability and aesthetics by allowing seamless relocation and easy detachment.
Implementation Method 1
A vacuum suction device has a semi-spherical or conical suction pad of synthetic rubber or flexible plastic which is sucked to a tile wall or a glass surface. As the internal pressure of the suction pad decreases, the suction pad may be kept sucked to a plane

AI summary
A vacuum suction device including a suction pad having a concave inner surface. The vacuum suction device also includes a vent hole penetrating from the concave inner surface of the suction pad to an outer surface of the suction pad. The vacuum suction device also includes a valve member disposed on the outer surface of the suction pad. As a pressure of a space, formed by an inner space of the suction pad, decreases, the valve member closes the vent hole from the outer surface of the suction pad.
