Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Silent electric motor vehicles pose a safety risk due to their quiet operation, which can be mitigated by acoustic warning systems, but these systems generate noise pollution for passengers through vibrations, and existing solutions are costly and complex to install.
Innovation Solution
A mounting support for an audio alarm device on the vehicle body that filters vibrations using a robust, space-saving design with a thin sheet structure and integrated fixing brackets, avoiding the need for additional damping materials and simplifying installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If acoustic warning systems are installed to signal the approach of silent motor vehicles, then safety alert functionality is improved, but noise pollution for passengers increases due to vibrations
Solution Approach 1:
The mounting support acts as an intermediary element between the audio alarm device and the vehicle body. It includes a plate with fixing brackets that mechanically couples the device to the body while isolating vibrations. The support structure filters vibrational energy before it reaches the vehicle body, thereby reducing noise pollution for passengers while maintaining the safety alert function.
2Object-affected harmful factors
If vibration damping means are added to reduce noise pollution, then noise pollution for passengers is reduced, but device complexity and cost increase
Solution Approach 1:
The mounting support is designed to be self-sufficient in filtering vibrations without requiring additional separate damping components. The plate structure with its specific geometry and fixing brackets inherently provides vibration filtering capability. This self-service approach eliminates the need for extra damping materials or complex vibration isolation systems, keeping the structure simple and cost-effective.
3Object-affected harmful factors
If the support structure is made robust to reduce vibrations, then noise pollution for passengers is reduced, but the space required for installation increases
Solution Approach 1:
The mounting support utilizes a thin plate structure with integrated fixing brackets that provides robust vibration filtering without requiring substantial volume. The plate acts as a flexible yet stiffening element that filters vibrations while maintaining a compact form factor suitable for congested installation environments on vehicle bodies.
4Volume of moving object
If the thickness of the plate is reduced to save space, then installation space is reduced, but structural strength decreases
Solution Approach 1:
The mounting support compensates for reduced plate thickness by utilizing the third dimension through vertically extending fixing brackets. These brackets provide additional structural strength and mounting capability without increasing the horizontal footprint. The brackets transfer loads to multiple attachment points on the vehicle body, maintaining structural integrity despite the thin plate design.

AI summary
The invention relates to a support (2) for mounting a sound alarm device of an AVAS on the body of a quiet motor vehicle. The support (2) comprises a mounting plate (4) extending longitudinally (L1) and transversely (T) in its extension plane. The mounting plate (4) forms in its plane a base (6) for receiving the sound alarm device and is provided with at least one lug (5a, 5b) for fastening the support (2) to the body of the vehicle, said lug extending vertically (V1) perpendicularly to the plane of the mounting plate (4).
