Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current assembly systems for superimposed supports in vehicles fail to effectively isolate environments from mechanical vibrations, requiring complex and costly solutions to achieve both good insulation and reduced vibration transmission.
Innovation Solution
An assembly device with an obturation body, a spacer, and a bonding system that includes an elastically deformable link system to absorb mechanical vibrations, allowing the shutter body and spacer to move closer along a main axis, thereby reducing vibration transmission while maintaining the superimposed configuration of the supports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional assembly devices are used to join two supports, then the supports can be securely assembled with good rigidity and insulation, but mechanical vibrations are transmitted from one environment to another
Solution Approach 1:
The patent incorporates a damping element in advance within the assembly device, positioned between the first and second supports. This element is designed to absorb mechanical vibrations before they can be transmitted from the engine compartment to the passenger compartment, thereby resolving the contradiction between maintaining assembly rigidity and preventing vibration transmission.
Solution Approach 2:
The damping element acts as an intermediary component between the first support (structural wall) and the second support (insulating panel). This mediator absorbs and dissipates mechanical vibrations while allowing the supports to remain securely connected, thus preventing harmful vibration transmission while maintaining assembly reliability.
2Object-affected harmful factors
If damping devices are added to reduce vibration transmission, then mechanical vibrations can be reduced, but the solution becomes complex and expensive in terms of manufacturing and implementation
Solution Approach 1:
The patent merges the damping function with the assembly device itself by integrating a damping element into the existing structure. The damping element is incorporated as part of the assembly mechanism that joins the first and second supports, eliminating the need for separate damping devices and reducing manufacturing complexity while still achieving vibration reduction.
Solution Approach 2:
The assembly device is designed to perform multiple functions simultaneously: it provides structural support, ensures thermal and acoustic insulation, and dampens mechanical vibrations. By making the assembly device multi-functional, the patent avoids the need for additional specialized damping components, thereby reducing device complexity and manufacturing costs while effectively reducing vibration transmission.

AI summary
An assembly device (10) for first and second superimposed supports (100, 200) includes a plug body (20) fixed by insertion to plug an opening (102) in the first support (100), and a spacer (30) axially offset from the body (20) and comprising bearing elements against the second support (200) to hold the second support (200) in position. A linkage system (40) mechanically connects the plug body (20) and the spacer (30) and can axially deform elastically in such a way as to provide an elastically deformable and damping mechanical connection between the plug body (20) and the spacer (30).
