Nested Suction Cap with Pressing Element for Laptop Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional suction caps require a larger working space and are inconvenient for fixing laptop computers due to the need for applying force to change pressure or contact area, making them unsuitable for size-limited devices like laptops.
Innovation Solution
A fixing device integrated into an electronic device, comprising a suction cap, elastic element, cover portion, and pressing element, where the pressing element, typically a button and spherical ball, controls the suction cap's contact with a plane by blocking airflow to maintain adhesion, allowing stable fixation without the need for extensive space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional suction caps are used to fix electronic devices, then the suction cap can adhere to the plane, but it requires a larger working space and needs force application to change pressure or contact area
Solution Approach 1:
The suction cap is nested within the electronic device case, with the pressing element housed inside the suction cap body. This nested structure allows the fixing device to be integrated into the limited space of the electronic device without requiring external working space for operation.
Solution Approach 2:
The elastic element automatically restores the pressing element to its initial position after pressing, and the suction cap automatically maintains its adhesion without requiring continuous force application. The system serves itself by using elastic recovery and atmospheric pressure to maintain fixation.
2Reliability
If conventional suction caps require force application to change pressure, then adhesion can be achieved, but it becomes inconvenient and user unfriendly
Solution Approach 1:
The elastic element automatically restores the pressing element to its initial position after pressing, and the suction cap automatically maintains its adhesion without requiring continuous force application. The system serves itself by using elastic recovery and atmospheric pressure to maintain fixation.
Solution Approach 2:
The pressing element is designed to be movable during pressing operation but automatically returns to its initial position through elastic restoration. This dynamic behavior allows easy operation while maintaining stable adhesion during use.
3Reliability
If the pressing element blocks air flow to the accommodating area, then adhesion is maintained, but the structure becomes more complex
Solution Approach 1:
The pressing element combines multiple functions: it presses the suction surface against the plane, blocks air flow to the accommodating area to maintain adhesion, and serves as the operational interface for the user. This merging of functions reduces the need for separate components.
Solution Approach 2:
The pressing element serves multiple purposes: it transmits pressing force to the suction surface, acts as an air flow barrier, and provides the user interface for activation. This multi-functionality simplifies the overall structure while maintaining adhesion reliability.

AI summary
A fixing device and an electronic device using the same are disclosed, wherein the fixing device is mounted in the electronic device's case for fixing the electronic device on a plane. The fixing device includes a suction cap, a cap cover, an elastic element, and a pressing element. The suction cap includes a suction section and a suction cap main body. The suction section has a suction surface and the body contains an accommodating area for accommodating the elastic element. The cover portion has a bottom part which is connected to a cover portion main body of the cap cover. The pressing element includes a pressing part and of which the shape matches the accommodating area. When the pressing element is pressed, the air flow within the accommodating area is blocked by the pressing part substantially.
