Vacuum Mount Connection for Impact-Resistant Quick Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connecting devices for attaching electronic devices, such as cameras or mobile phones, to helmets or vehicles lack ease of use and reliability under impact loads, as they often require precise operation to secure and release the attachment, and may not effectively absorb impulse forces without loosening.
Innovation Solution
A connecting device featuring a closure module with a housing assembly, an adjustable tilting adjusting element, and a vacuum element that creates a negative pressure effect for secure attachment, allowing easy closure and intuitive release through various tilting movements, and optionally enhanced with magnetic elements for additional holding force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a vacuum element is used to secure attachment, then holding force is improved, but ease of operation deteriorates due to difficulty in release
Solution Approach 1:
The patent extracts the vacuum sealing function from the entire connecting device by introducing a detachable sealing element that can be independently removed. This allows the vacuum effect to be maintained during attachment while enabling easy release by simply detaching the sealing element, resolving the contradiction between strong holding force and ease of release.
Solution Approach 2:
The patent implements dynamic operation by allowing the sealing element to transition between attached and detached states. The sealing element can be dynamically removed to release the vacuum effect for easy detachment, then reattached to restore the vacuum holding force, enabling flexible control between strong attachment and easy release.
2Strength
If magnetic elements are added for additional holding force, then strength is improved, but device complexity increases
Solution Approach 1:
The patent merges the vacuum holding mechanism with magnetic elements in a integrated connecting device. The magnetic elements work synergistically with the vacuum effect to provide enhanced holding force, while the overall structure remains unified and manageable, balancing improved strength with acceptable device complexity.
3Manufacturing precision
If the adjusting element requires precise operation, then manufacturing precision is improved, but ease of operation deteriorates
Solution Approach 1:
The patent implements self-alignment functionality where the sealing element automatically positions itself relative to the connecting device during attachment. This self-service mechanism eliminates the need for precise manual alignment operations while maintaining manufacturing precision, resolving the contradiction between precision and ease of operation.
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 secure and resilient attachment under impact loads, allowing easy operation to attach and detach electronic devices without requiring precise movements, while effectively absorbing and dissipating impulse forces.
Implementation Method 1
the vacuum element and the attachment assembly are held together by a vacuum effect between the vacuum element and the attachment assembly
Implementation Method 2
The closure module has a first magnetic element and the attachment assembly a second magnetic element, wherein the first and second magnetic elements are magnetically attracted to each other in the connected position
