Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional multi-wheeled vehicles experience disorientation during turns, leading to gravitational forces pulling the driver away from the controls, as they do not lean in conjunction with the turning forces, potentially causing loss of control.
Innovation Solution
A suspension system with a frame, control arm, actuator, proportional control valve, and pendulum that adjusts the angular orientation of the control arms relative to the frame using pressurized fluid, allowing the vehicle to lean into turns and maintain driver orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional suspension is used to cushion force inputs, then the vehicle body remains level with the road, but the operator experiences gravitational forces pulling away from controls during turns
Solution Approach 1:
The suspension system transitions from a static level position to a dynamic leaned position during turns. The actuator actively adjusts the control arm angle relative to the road surface, allowing the vehicle body to lean into turns while maintaining driver control stability, thus resolving the contradiction between control reliability and driver orientation
2Ease of operation
If the vehicle body remains level during turns, then suspension cushions force inputs, but the operator becomes disassociated from controls in extreme situations
Solution Approach 1:
The system changes the orientation parameter of the vehicle body from level (0 degrees) to leaned (angled relative to road). By adjusting the control arm angle through the actuator, the vehicle body leans into turns to match gravitational forces, improving driver orientation while maintaining control stability through active parameter adjustment
3Adaptability or versatility
If traditional suspension design is used, then the vehicle structure is simple, but the vehicle cannot lean into turns to correlate with forces experienced by driver
Solution Approach 1:
The suspension system is segmented into distinct functional components: control arm, actuator, and vehicle body. This segmentation allows the control arm to independently adjust its angle relative to the road surface, enabling the vehicle body to lean into turns while keeping the overall system complexity manageable through modular design

Function Achieved in This Case
Enables multi-wheeled vehicles to perform turns while maintaining driver control by simulating the leaning motion of two-wheeled vehicles, reducing the risk of losing control due to gravitational forces.
Implementation Method 1
a pendulum coupled to the valve core having a neutral position and an offset position, wherein, when the pendulum is in the neutral position, the valve core is in the first position and when the pendulum is in the offset position the valve core is in the second position
Implementation Method 2
altering the angular orientation of the first and second control arm relative to the frame by selectively providing a pressurized fluid to the first and second actuator

AI summary
A suspension system with a frame pivotally coupled to a control arm, an actuator pivotally coupled between the frame and the control arm, a control valve fluidly coupled to the actuator, a valve core positioned within the control valve and being slidable between a first position and a second position, and a pendulum coupled to the valve core having a neutral position and an offset position. Further, when the pendulum is in the neutral position, the valve core is in the first position and when the pendulum is in the offset position the valve core is in the second position.
