Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If planar amortizing elements (flat plates with channels or slits) are used, then manufacturing is simple and cost is low, but they cannot compensate for assembly defects and stabilize parts with dimensional mismatches
Solution Approach 1:
The patent transitions from planar (2D) amortizing elements to three-dimensional L-shaped elements with horizontal and vertical walls. This dimensional change enables the elements to compensate for assembly defects and stabilize parts with dimensional mismatches while maintaining manufacturing simplicity through injection molding processes.
Solution Approach 2:
The patent introduces corrugations in the vertical wall and adjustable protrusions on the horizontal wall to modify the mechanical parameters of the amortizing element. These parameter changes enable the element to adapt to different assembly defects and provide reliable stabilization while remaining cost-effective.
2Strength
If rigid materials are used for parts, then structural strength is high, but dimensional mismatches and play tolerances cause oscillation and noise during assembly
Solution Approach 1:
The patent introduces a plastic or elastomer amortizing element as an intermediary between rigid parts. This intermediary material absorbs dimensional mismatches and play tolerances through its elastic properties, preventing oscillation and noise while maintaining the structural strength of the rigid components.
Solution Approach 2:
The patent changes the material parameter from rigid to elastic/plastic for the amortizing element. This parameter change allows the element to deform and compensate for dimensional mismatches between rigid parts, eliminating harmful oscillations and noise while preserving overall structural integrity.
3Reliability
If amortizing elements are designed for specific applications, then performance for that application is optimized, but adaptability to other sectors and components is limited
Solution Approach 1:
The patent designs the amortizing element with a universal L-shaped geometry that can function in multiple orientations and applications. The element can be used for both flat surface contact and orthogonal surface contact, making it adaptable to various sectors and components while maintaining optimized performance through its corrugated and protrusion features.

Function Achieved in This Case
Ensures stability and soundproofing by compensating for shape and dimensional mismatches, offering adaptability and compatibility across various sectors with reduced noise and vibration.
Implementation Method 1
A multifunctional plastic or elastomer amortizing element with customizable shapes and modular design, featuring corrugations, protrusions, and inserts to compensate for assembly defects, providing elastic tension and stability between overlapping parts
Implementation Method 2
The element 24 as shown in Fig. 1, has a horizontal flat wall 25, whereas the vertical wall 26 is corrugated in parallel to the horizontal wall... the corrugations, both horizontal and vertical, are provided to give each amortizing element a 'spring' effect that helps to compensate lateral play and transversal blocking of the joined parts

AI summary
The invention concerns an amortizing element to be placed between overlapping parts and/or inserted one into the other to ensure stability and soundproofing of the connection by eliminating the assembly defects and play, characterized by a bi or three-dimensional plastic material body, structured to form at least one horizontal supporting section and at least one section for the protection of at least some peripheral areas of the contact surfaces between said parts to be joined. Every element can also be equipped with a tongue or ribs or protrusions to increase the amortizing.
