Solution Overview

Problem

Conventional air suspension systems in vehicles are preset to a specific weight accommodation level, resulting in nonsmooth and uncomfortable rides, particularly for elderly, overweight, or female riders, and combining air suspension with liquid damping leads to reliability issues due to leakage and contamination.

Innovation Solution

An adjustable air suspension shock system with a built-in rotatable damper device that allows for adjustable suspension height and stiffness, using an inflatable air spring or rubber/elastomeric airbag, a shock absorber, and a hydraulic damper, enabling the user to customize the ride based on weight, height, and preference, with the ability to raise or lower the rear shocks through full suspension travel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If conventional air suspension systems are preset to a specific weight accommodation level, then the suspension structure is simple and easy to manufacture, but the ride comfort deteriorates for different riders (elderly, overweight, women)

Engineering Contradiction:
Improvepreset suspension structureVSAvoidride comfort
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The patent applies dynamics by making the suspension system adjustable rather than fixed. The air spring allows the suspension to dynamically adapt to different weight conditions and rider preferences, enabling transformation between soft and firm ride characteristics while maintaining a relatively simple overall structure.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of air pressure in the air spring to achieve different suspension characteristics. By adjusting the amount of air in the elastomeric tube, the system can accommodate different weight levels and ride preferences without changing the fundamental suspension structure, thus maintaining ease of manufacture while improving ride comfort.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If conventional air suspension systems use fixed air pressure, then the system is simple and reliable, but the ride becomes nonsmooth and uncomfortable

Engineering Contradiction:
Improvesuspension system reliabilityVSAvoidride smoothness
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system transitions from fixed to dynamic air pressure adjustment. The adjustable air spring allows riders to change the air pressure according to their weight and comfort preferences, creating a smooth and comfortable ride while maintaining system reliability through the robust elastomeric tube design and simple adjustment mechanism.

Inventive Principle:
Principle #15Dynamics

3Device complexity

If air suspension is combined with liquid damping in the same housing, then the device complexity is reduced, but reliability deteriorates due to leakage and contamination

Engineering Contradiction:
Improvecombined air suspension and dampingVSAvoidleakage and contamination resistance
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent segments the air suspension system and liquid damping system into separate housings. The air spring operates in one housing while the shock absorber with liquid damping operates in another housing, eliminating the risk of leakage and contamination between the two systems while maintaining reasonable device complexity through coordinated design.

Inventive Principle:
Principle #1Segmentation

4Adaptability or versatility

If preset suspension is used for maximum weight accommodation, then the suspension can handle all weight levels, but the ride is harsh for lighter riders

Engineering Contradiction:
Improveweight accommodation rangeVSAvoidride comfort for individual riders
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent uses parameter changes by adjusting the air pressure in the elastomeric tube to match different weight levels. Lighter riders can reduce the air pressure for a softer ride, while heavier riders can increase it for maximum weight accommodation, thus achieving both versatility and individualized comfort.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system becomes dynamic and adaptable to different riders through adjustable air pressure. Rather than being fixed for maximum weight, the suspension can be tuned in real-time to match the actual load and rider preferences, ensuring comfort across the full weight range.

Inventive Principle:
Principle #15Dynamics

AI summary

Adjustable air suspension shocks with rotatable damper assemblies, apparatus, systems and method for motor vehicles, such as automobiles, vans, trucks, off the road vehicles, motorcycles, the like. Deflating interior air springs/airbags (bladders) allows for pistons on shock absorbers to expand outward separating lower front and rear frame portions which effectively lowers the motor vehicle to the ground surface and for the driver to have a firmer ride. Inflating the airbags (bladders) allows for the pistons on the shock absorbers in the devices to retract so that devices have a more shock absorbing effect giving the driver and passenger(s) a smoother ride, which also raises the motor vehicles above the ground surface. A sleeve attached to the air shock allows for a damper assembly to rotate relative to the air shock so that it can be installed within mounting brackets where the axial mounting openings need not be perpendicular to one another.
