Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suction devices are insufficient to support tablet computers, with limited suction force, potential air leakage leading to accidental drops, and lack of orientation adjustment, making them unsuitable for holding and displaying tablets effectively.
Innovation Solution
An omni-direction rotatable dual-cup suction device with two suction cups connected through adjustable evacuation structures and a collar-bar mechanism, allowing for secure attachment to surfaces and adjustable orientation of the tablet computer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple suction cup is used to hold a tablet computer, then the device structure is simple, but the suction force is insufficient to support the tablet computer
Solution Approach 1:
The patent combines two suction cups into a single integrated device, where one suction cup attaches to the tablet computer and the other attaches to a support surface. This merging approach doubles the total suction force available to hold the tablet, resolving the contradiction between structural simplicity and sufficient holding force.
2Force
If a depression-type suction device is used, then the suction force is slightly enlarged, but the stroke is limited making the suction force insufficient and air leakage cannot be easily identified
Solution Approach 1:
The patent incorporates color-changing indicators on the suction cups that change color when air leakage occurs or when the suction force is insufficient. This visual feedback mechanism enables easy detection of air leakage and maintains reliability while preserving the enlarged suction force from the depression-type design.
3Force
If a pumping-type suction device is used, then a large suction force is achieved with alarm mark, but adjustment of angular position is not possible and lacks suitable structure for holding an article
Solution Approach 1:
The patent incorporates a rotating joint mechanism that allows the suction cup assembly to rotate and adjust to various angular positions. This dynamic adjustment capability enables the device to adapt to different orientations and angles, resolving the contradiction between maintaining large suction force and enabling orientation adjustment for versatile use.
4Adaptability or versatility
If a clamp or rack is used to hold the tablet computer on a suction cup, then the tablet can be held, but the clamping force is insufficient for a tablet computer
Solution Approach 1:
Instead of using a separate clamp or rack with insufficient clamping force, the patent merges the holding function directly into the suction cup mechanism itself. The suction cup creates a vacuum seal that directly adheres to the tablet computer surface, providing sufficient holding force without requiring additional clamping structures.
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 device provides a stable and adjustable solution for holding and orienting tablet computers, enhancing their usability and display effectiveness by allowing optimal positioning for user comfort and exhibition purposes.
Implementation Method 1
two suction cups, which are respectively combined with and in communication with two evacuation structures, so that the two evacuation structures can evacuate air from the suction cups to induce vacuum suction forces

AI summary
An omni-direction rotatable dual-cup suction device includes two suction cups, which are respectively combined with and in communication with two evacuation structures, so that the two evacuation structures can evacuate air from the suction cups to induce vacuum suction forces. The two suction cups are respectively provided with a mounting seat and an attaching seat for securely coupling the two evacuation structures. The mounting seat includes a pillar fixed thereto. A collar receives a ball end of a bar therein and is attached to the pillar. The ball-ended bar is coupled to a threaded rod, which extends through an internally-threaded locking knob and received into the attaching seat to be secured by a nut. With such an arrangement, one of the suction cups can be attached to a planar fixture surface, while the other suction cup can be used to hold an article and is orientation adjustable in any direction.
