Thin Suction Stand With Slide Valve for Stable Device Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stands for electronic devices are thick due to the protruding suction mechanism, which affects the device's overall thickness and design.
Innovation Solution
An electronic device stand with a suction member and a slide valve that generates negative pressure by deforming elastically when under external force, allowing the stand to adhere to the surface without protruding mechanisms, thus reducing the stand's thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional suction mechanism is used, then the stand can adhere to the placement surface, but the suction mechanism protrudes vertically upward increasing the stand's thickness
Solution Approach 1:
The invention inverts the conventional suction mechanism design by placing the suction cup in the base rather than having it protrude upward. The slide valve mechanism is integrated into the base structure, with the valve body sliding within the base to control air intake. This inversion allows the suction function to be achieved without increasing the stand's vertical thickness, as all components are contained within the base's horizontal footprint.
Solution Approach 2:
The invention nests the slide valve mechanism within the base structure. The valve body is positioned inside the base, sliding along an guide groove formed in the base. The ventilation hole passes through the base, and the valve body covers this hole when in the closed position. This nesting arrangement integrates multiple functions (suction control, air intake regulation) within the existing base volume, eliminating the need for external protruding components.
2Reliability
If the suction mechanism protrudes from the base, then the suction function is achieved, but the device complexity increases due to additional components
Solution Approach 1:
The invention merges the suction mechanism with the base structure. The suction cup is integrated into the base, and the slide valve mechanism is combined with the base's internal geometry. The guide groove for the valve body is formed directly in the base, and the ventilation hole is a through-hole in the base. This merging reduces the number of separate components and simplifies the overall structure while maintaining the suction function.
Solution Approach 2:
The base serves multiple functions: it provides structural support, houses the suction cup, contains the slide valve mechanism, and includes the ventilation hole. The slide valve body simultaneously controls air intake and moves along the guide groove within the base. This multi-functionality reduces the need for separate dedicated components, thereby reducing overall device complexity.

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 solution enables a reduction in the thickness of the stand while maintaining effective adhesion to the surface, enhancing the device's design and stability.
Implementation Method 1
the suction member generates the negative pressure in the gap by elastically deforming in a direction away from the placement surface when the stand is under an external force acting in the direction away from the placement surface
Implementation Method 2
includes a suction surface that adheres to the placement surface by negative pressure generated in a gap between the placement surface and the suction surface

AI summary
An electronic device includes a device body and a stand supporting the device body. The stand includes: a base; a suction member facing the lower surface of base, including a suction surface that adheres to the placement surface by negative pressure generated in a gap between the placement surface and the suction surface, and including a ventilation hole in fluid communication with the gap; and a slide valve, located between the base and the suction member, that slides along the lower surface of the base between opened and closed positions where the ventilation hole is opened and closed to let and interrupt air into the gap, respectively.
