Solution Overview
Problem
Existing vehicles lack efficient systems for adjusting the chassis height to facilitate easy passenger ingress and egress, particularly for vehicles with adjustable suspension systems.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a vehicle includes adjustable suspension systems to raise and lower the chassis, then passenger accessibility is improved, but the device complexity increases
Solution Approach 1:
The suspension system is divided into multiple independent dampers, each controlled by its own actuation assembly. This segmentation allows individual control of each wheel's height, enabling precise chassis leveling and improved accessibility while maintaining manageable complexity through modular design.
Solution Approach 2:
The system employs rotatable arms that can dynamically adjust between raised and lowered positions, allowing the chassis height to be continuously varied. This dynamic adjustment capability provides real-time accessibility improvements while the controlled nature of the movement manages system complexity.
2Ease of operation
If a rotatable arm actuation assembly is used to raise and lower the chassis, then ease of operation is improved, but the device complexity increases
Solution Approach 1:
The rotatable arm actuation assembly serves multiple functions: it raises and lowers the chassis, levels the vehicle on uneven surfaces, and can be controlled through various input methods (manual, automatic, wireless). This multi-functionality improves ease of operation while the integrated design manages complexity by combining multiple capabilities in a single assembly.
Solution Approach 2:
The rotatable arm acts as an intermediary mechanism between the motor and the damper, translating rotational motion into vertical displacement. This intermediary component simplifies the overall actuation system by providing a mechanical advantage and smooth motion transition, reducing the complexity of direct actuation mechanisms.
3Adaptability or versatility
If multiple dampers with individual actuation assemblies are installed at each wheel, then vehicle leveling capability is improved, but the device complexity increases
Solution Approach 1:
The vehicle suspension system is segmented into four independent damper units, each with its own actuation assembly. This segmentation enables independent control of each wheel's height, providing superior vehicle leveling capability and adaptability to uneven surfaces, while the modular architecture manages complexity through standardization of components.
Solution Approach 2:
The control module receives feedback from sensors about the vehicle's position and orientation, then adjusts each damper's height accordingly to achieve level positioning. This feedback control system improves vehicle leveling capability while the automated control reduces the operational complexity for the user.

AI summary
A system configured to raise and lower a chassis of a vehicle. The system includes a damper with a first end connected to the chassis and a second end that is opposite to the first end. An actuation assembly includes a rotatable arm and a motor configured to rotate the rotatable arm, the rotatable arm is connected to both the second end of the damper and a control arm of the vehicle. Rotation of the rotatable arm by the motor moves the damper between a raised position to raise the chassis and a lowered position to lower the chassis.
