Solution Overview

Problem

Vehicle seat adjustment systems and air suspensions have complex structures that occupy significant space and increase costs.

Innovation Solution

An integrated adjustment system that shares an air storage apparatus between a first air-receiving apparatus for vehicle height adjustment and a second air-receiving apparatus for seat position adjustment, reducing the overall system volume and cost by integrating functions such as vehicle height and seat position adjustment, while utilizing a control apparatus for coordinated control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate air storage apparatus are used for suspension system and seat adjustment system, then each system can be independently controlled, but the total system volume and space occupation increase significantly

Engineering Contradiction:
Improveindependent control capabilityVSAvoidtotal system volume
Core Design Contradiction:
ReliabilityVSVolume of stationary object

Solution Approach 1:

The patent combines the air storage apparatus of the suspension system and seat adjustment system into a single shared unit. The control apparatus manages both systems by selectively controlling air supply to different air receiving components (air springs for suspension, airbags for seat adjustment), achieving space reduction while maintaining functional independence through intelligent resource allocation

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The shared air storage apparatus serves multiple functions: it supplies air to air springs for vehicle height adjustment and to airbags for seat position adjustment. The control apparatus acts as a universal controller that can direct compressed air to different destinations based on operational requirements, making the air storage system multi-functional

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If separate air storage apparatus are used for suspension system and seat adjustment system, then each system has dedicated air supply, but the manufacturing cost increases

Engineering Contradiction:
Improvededicated air supplyVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent merges the air storage apparatus into a single shared component for both suspension and seat adjustment systems. This consolidation reduces the total number of components that need to be manufactured and assembled, thereby reducing manufacturing costs while maintaining dedicated air supply paths through the control apparatus's selective valve control

Inventive Principle:
Principle #5Merging (Combining)

3Volume of stationary object

If integrated air storage apparatus is shared between suspension and seat adjustment systems, then system volume and cost are reduced, but system complexity increases

Engineering Contradiction:
Improvetotal system volumeVSAvoidsystem complexity
Core Design Contradiction:
Volume of stationary objectVSDevice complexity

Solution Approach 1:

The control apparatus acts as an intermediary between the shared air storage apparatus and the two different systems. It manages the complexity by selectively controlling air distribution to air springs or airbags based on operational needs, absorbing the control complexity while allowing the physical system to remain simple and compact

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Provided are an integrated adjustment system and a vehicle. The system is applied to a vehicle. The integrated adjustment system includes: a first air-receiving apparatus and a second air-receiving apparatus, where the first air-receiving apparatus is configured to achieve a first function, the second air-receiving apparatus is configured to achieve a second function, and the first function is different from the second function; and an air storage apparatus (8), where the air storage apparatus (8) is connected to the first air-receiving apparatus to supply air to the first air-receiving apparatus, and the air storage apparatus (8) is connected to the second air-receiving apparatus to supply air to the second air-receiving apparatus. This significantly reduces a total volume of the integrated adjustment system, saves interior space of the vehicle, and reduces costs of the vehicle.
