Solution Overview

Problem

In vehicles, technical devices mounted under seats cause vibrations and noise due to direct transmission of oscillations and vibrations to the seat substructure paneling, compromising passenger comfort.

Innovation Solution

The seat substructure paneling is decoupled from the vehicle's basic structure using decoupling elements, ensuring no direct non-positive connection between the base support, seat support, and seat substructure paneling, which are independently attached, with the seat substructure paneling attached solely to the vehicle's floor, reducing vibration transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If technical devices are accommodated in boxes used as seat substructures, then passenger capacity is increased, but vibrations and noise are transmitted to the seat substructure paneling, adversely affecting passenger comfort

Engineering Contradiction:
Improvepassenger capacityVSAvoidvibrations and noise
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a damping element as an intermediary component between the base support and the seat substructure paneling. This damping element absorbs and dissipates vibrations before they reach the paneling, thereby reducing noise and improving passenger comfort while maintaining the space-efficient box design for increased passenger capacity

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent extracts the damping function from the structural components by introducing a separate damping element. This allows the base support to maintain its structural integrity while the damping element specifically addresses vibration transmission, separating the structural support function from the vibration isolation function

Inventive Principle:
Principle #2Taking out (Extraction)

2Stability of the object's composition

If the seat substructure paneling is directly connected to the base support and seat support, then structural stability is improved, but vibration transmission to the paneling increases

Engineering Contradiction:
Improvestructural stabilityVSAvoidvibration transmission
Core Design Contradiction:
Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The damping element serves as a mediator between the rigid base support and the seat substructure paneling. It maintains the necessary structural connection while introducing vibration-damping properties that prevent direct transmission of oscillations to the paneling, thus preserving structural stability while reducing harmful vibrations

Inventive Principle:
Principle #24Intermediary (Mediator)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

This configuration significantly reduces vibrations and noise transmitted to the seat substructure paneling, enhancing passenger comfort by mechanically decoupling the floor from the vehicle's supporting framework.

Implementation Method 1

the floor being decoupled from the basic structure of the vehicle and neither between the base support and the seat substructure paneling nor between the seat support and there is a direct non-positive connection between the supporting framework of the vehicle, to which the base support is attached, and the floor of the vehicle, to which the seat sub-panel is attached
