Segmented Spherical Component Connection with Blocking Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component connections requiring high disassembly forces after assembly with clip elements, which are difficult to detach due to their construction, necessitate a solution for a form-fitting, releasable connection that can be assembled and disassembled with low forces while maintaining high strength.
Innovation Solution
A component connection featuring a male securing element with coaxial interconnected spheres and a second component with a blocking clearance, where a blocking element engages form-fittingly with the spheres to resist detachment, allowing for low-force assembly and disassembly, and providing high retention forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a clip element is used to clamp the two components together on the male securing element, then the component connection achieves high retention strength, but very high disassembly forces are required to detach the clip element
Solution Approach 1:
The securing element is segmented into multiple spherical sections (first spherical section and second spherical section) that can independently interact with the blocking element. This segmentation allows the blocking element to engage with individual spheres rather than the entire securing element, reducing the force required to disengage while maintaining retention strength through the cumulative effect of multiple engagement points.
Solution Approach 2:
The blocking element serves as an intermediary component between the male securing element and the second component. It mediates the connection by engaging with the spherical sections and providing a controlled disengagement mechanism, allowing the connection to be assembled and disassembled with low forces while maintaining high retention during operation.
2Strength
If a male securing element with multiple interconnected spheres is used, then the form-fitting connection provides high retention forces, but the complexity of the securing element structure increases
Solution Approach 1:
The securing element uses spherical sections instead of complex geometric shapes. The spherical geometry provides inherent rotational symmetry and smooth surfaces that simplify manufacturing while enabling the form-fitting engagement with the blocking element. The curved surface of the spheres naturally guides the blocking element into the correct engagement position, reducing the need for additional alignment features.

AI summary
A form-fitting, detachable component connection includes a first component and a male securing element that has at least two spheres which are arranged coaxially to one another and interconnected, or two spherical sections which are arranged coaxially to one another and interconnected. The male element protrudes from the first component. A second component is arranged such that the male securing element projects into a recess of the second component. The second component includes at least one blocking recess through which or into which a blocking element extends which bears against the male securing element from outside and form-fittingly engages between the spheres or the spherical sections thus opposing removal of the second component from the male securing element.
