Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fastening clip made of elastic material is used to connect two components, then the connection can be established with material adjustment, but the damping ability with respect to component vibrations is insufficient
Solution Approach 1:
The connecting element is divided into two distinct parts: a fastening clip for establishing the connection and a separate damping element for vibration absorption. This segmentation allows each component to be optimized for its specific function - the clip provides adaptability through material adjustment while the damping element specifically addresses vibration harmful factors
Solution Approach 2:
A dedicated damping element is introduced as an intermediary component between the fastening clip and the connected components. This mediator specifically addresses the harmful vibration transmission by absorbing and dissipating vibrational energy, while the fastening clip maintains the connection with its material adjustment capability
2Reliability
If a springing construction is used to establish connection between components, then the connection can be secured against releasing moments, but no damping properties are developed
Solution Approach 1:
The invention merges two previously separate functions into a single integrated connecting element: the fastening function (securing against releasing moments) and the damping function (absorbing vibrations). The connecting element combines a springing construction for reliability with a damping element for vibration absorption, achieving both objectives simultaneously
3Stability of the object's composition
If a connecting sleeve with blocking pin is used to lock component openings, then the connection stability is improved, but the damping behavior is reduced due to limited radial deformability
Solution Approach 1:
The connecting element maintains dynamic capability through its springing construction that allows controlled deformation. Unlike rigid blocking pin solutions that completely restrict movement, this design permits limited radial deformability to absorb vibrations while still providing sufficient stability to maintain the connection between components

AI summary
An elastic connecting block with which, by receiving a connecting pin, at least two components can be connected together via a respective component opening. The connecting block, which is formed as a single piece, comprises a central bearing block with two mutually opposing bearing surfaces for the components to be connected. A locking flange, which can be engaged in a component opening, is provided on the first bearing surface. On the other bearing surface, a widening flange is provided, which can be expanded by a spherical head of the connecting pin such that the widening flange is held via an axial undercut in the second component opening of the second component.
