Connecting apparatus for detachably connecting two assemblies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connecting devices for attaching electronic devices, such as cameras or mobile phones, to assemblies like helmets or vehicles struggle to balance ease of attachment and detachment while withstanding impact forces, and often require complex designs or additional components.
Innovation Solution
A connecting device featuring a first and second connection part that allow relative movement perpendicular to the attachment direction, utilizing a vacuum element and magnetic elements to create a secure hold that can be easily released by adjusting the vacuum element's position or magnetic alignment, allowing for simple detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a vacuum element is used to secure an electronic device to an assembly, then the holding force is improved, but the device becomes difficult to detach suddenly due to negative pressure forces
Solution Approach 1:
The connecting parts are designed to be movable relative to each other in the closed position, allowing dynamic adjustment that automatically releases the vacuum seal during movement, enabling easy detachment without sudden tearing forces
Solution Approach 2:
The movable mounting preliminarily positions the connecting parts such that any unintended movement automatically breaks the vacuum seal before significant detachment force can build up, preventing sudden tearing
2Reliability
If magnetic elements are added to improve the hold, then the holding force is improved, but the device complexity increases
Solution Approach 1:
The magnetic elements are integrated into the existing connecting parts structure, combining the holding function with the existing vacuum mechanism rather than adding separate magnetic components, thereby improving hold without significantly increasing device complexity
3Reliability
If a connecting device is designed to be robust against impact forces, then the reliability is improved, but the installation space required increases
Solution Approach 1:
The connecting parts utilize flexible vacuum elements that can absorb impact forces through elastic deformation rather than requiring rigid structural components, achieving impact resistance with minimal installation space
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 attachment that absorbs impact forces while being easy to open and close, with a space-saving design that does not significantly contribute to the installation space, using fewer components and ensuring easy detachment without force.
Implementation Method 1
a vacuum element that can be connected to the surface section of the first connecting part along an application direction, rests against the surface section in a connected position and is held against the surface section when subjected to vacuum pressure
Implementation Method 2
a magnetic element is arranged on the suction cup that can interact with a magnetic element on the windshield to improve the hold

AI summary
The invention relates to a connecting apparatus for detachably connecting two assemblies (1, 2), said connecting apparatus comprising: a first connecting part (10) which is associated with a first of the assemblies (1, 2) and forms a surface portion (100); and a second connecting part (20) which is associated with a second of the assemblies (1, 2) and has a vacuum element (23) which can be connected to the surface portion (100) of the first connecting part (10) along an attachment direction (A) and, in a connected position, bears against the surface portion (100) with a vacuum effect. In the connected position, the first connecting part (10) is mounted so as to be movable relative to the second connecting part (20) along a plane perpendicular to the attachment direction (A), it being possible to change the position of the vacuum element (23) relative to the surface portion (100) by moving the first connecting part (10) relative to the second connecting part (20) and thereby to remove the vacuum effect in order to detach the first connecting part (10) and the second connecting part (20) from one another.
