Solution Overview

Problem

Existing vehicle seat stabilization systems for commercial vehicles are ineffective in directly reacting to deflections, as they rely on detecting and compensating for volume changes in pneumatic springs, which is a slow and inefficient process.

Innovation Solution

A vehicle seat stabilization apparatus featuring a rotary element mounted to rotate about a first axis, generating a torque to counteract rotational movements caused by uneven terrain, with adjustable rotational frequency and moment of inertia to adapt to terrain and driver comfort, and optionally using a cardanic suspension for multi-directional movement detection and actuation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If pneumatic spring volume change detection and compensation is used, then seat stabilization is achieved, but the response time is slow and the system complexity increases

Engineering Contradiction:
Improveseat stabilization effectivenessVSAvoidresponse time to deflection
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces the pneumatic spring volume detection and control system with a mechanical gyroscopic stabilization system. The rotary element generates a rotational pulse that directly counteracts seat deflection through mechanical torque, eliminating the need for sensors, control units, and air supply systems, thereby achieving immediate response without time loss.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The gyroscopic stabilization system is self-regulating through the physical properties of the rotating element. When the seat deflects, the rotational pulse automatically generates a counteracting torque without requiring external detection or control intervention, enabling instantaneous self-correcting stabilization.

Inventive Principle:
Principle #25Self-service

2Reliability

If pneumatic spring volume change detection and compensation is used, then seat stabilization is achieved, but the device complexity increases

Engineering Contradiction:

Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces the complex pneumatic control system with a simple mechanical gyroscopic device. The rotational element mounted on the vehicle seat generates stabilization torque through its rotation about a first rotational axis, eliminating sensors, control units, valves, and air supply infrastructure, thereby dramatically reducing device complexity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The invention extracts and removes the complex control apparatus and air supply system from the stabilization mechanism, retaining only the essential rotational element that provides stabilization through pure mechanical gyroscopic effects, thereby simplifying the overall system architecture.

Inventive Principle:
Principle #2Taking out (Extraction)

3Adaptability or versatility

If rotary element with adjustable rotational frequency is used, then adaptability to different terrains and comfort levels is improved, but the device complexity increases

Engineering Contradiction:

Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements adjustability of the rotational frequency of the rotary element, allowing the stabilization characteristics to be dynamically changed according to different operating conditions such as terrain roughness and driver comfort requirements, while maintaining a relatively simple mechanical adjustment mechanism.

Inventive Principle:
Principle #15Dynamics

AI summary

Vehicle seat which is arranged on a vehicle body, is movable relative to the vehicle body and comprises at least one spring apparatus and/or at least one damping apparatus for displacing and for absorbing oscillations in the vertical and/or horizontal direction, and at least one seat stabilization apparatus arranged on the vehicle seat for stabilizing the vehicle seat in the vertical and/or horizontal direction, wherein the seat stabilization apparatus comprises at least one rotary element which is mounted so as to rotate about a first rotational axis, can rotate at a rotational frequency and by means of which a torque can be generated by a force acting from outside on the vehicle seat and on the rotational pulse generated by the rotary element, which torque counteracts a rotational movement of the vehicle seat and/or the vehicle body generated by the force about an actual and/or imaginary second rotational axis.
