Nested Dual Suction Cup Mount for Leak-Resistant Vehicle Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional single-suction-cup vehicle-mounted supports are prone to air leakage and loss of suction due to bumping or aging, leading to potential accidents when the support falls off during driving.
Innovation Solution
A two-suction-cup vehicle-mounted support fixing device with a pressure valve switch, pull handle, and reset spring, where the outer and inner suction cups work together to maintain stability and facilitate quick suction and release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single suction cup is used to fix the support, then the device structure is simple, but the suction cup softens and leaks air due to bumping or aging, causing the support to fall off
Solution Approach 1:
The single suction cup is divided into multiple independent suction cups (outer suction cup and inner suction cup). Each suction cup can independently maintain suction, so if one fails due to bumping or aging, the other can still hold the support in place, significantly improving reliability.
Solution Approach 2:
The patent designs a system where the inner suction cup is positioned inside the outer suction cup, creating a redundant structure that anticipates potential failures. This beforehand cushioning ensures that even if the outer suction cup fails, the inner suction cup provides backup support to prevent the support from falling off.
2Reliability
If a traditional single suction cup is used, then the device is easy to operate, but it is easy for the support to fall off during driving due to air leakage
Solution Approach 1:
The pressure valve switch automatically responds to pressure changes caused by bumping or aging. When the outer suction cup loses suction, the pressure change triggers the valve to automatically adjust, maintaining the suction force without requiring manual intervention, thus preserving both reliability and ease of operation.
Solution Approach 2:
The system incorporates a pressure valve switch that provides feedback on the suction status. When the suction force changes due to bumping or aging, the valve detects the pressure change and automatically adjusts to maintain proper suction, ensuring continuous reliable fixation during driving.
3Reliability
If a two-suction-cup structure is implemented, then the suction effect is firmer and more stable, but the device complexity increases with additional components
Solution Approach 1:
The inner suction cup is nested within the outer suction cup, with the inner suction cup positioned inside the cavity of the outer suction cup. This nested arrangement allows two suction cups to function together in a compact configuration, providing firmer and more stable suction while minimizing the increase in overall device complexity.
Solution Approach 2:
The patent combines the outer suction cup and inner suction cup into a single integrated fixing device, with both suction cups working together to provide enhanced suction stability. The merged structure allows the benefits of multiple suction cups to be achieved while maintaining a unified and manageable device design.
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 two-suction-cup structure provides a more stable and reliable fixing mechanism, preventing accidental falls and ensuring the support remains securely attached to the vehicle surface.
Implementation Method 1
A suction cup type fixing support uses power of a suction cup to suck a support main body to a smooth surface in a vehicle
Implementation Method 2
a reset spring is arranged between the suction cup main body and the mounting seat
