Rotating Passenger Compartment for Dynamic Seating Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicles do not provide adequate comfort for occupants in varying positions within the passenger compartment, as they lack the ability to adjust orientation and seating configurations dynamically to accommodate different user preferences and needs.
Innovation Solution
A motor vehicle design featuring a chassis with a single vehicle axle that allows the vehicle body and passenger compartment to rotate relative to the seat device, enabling the passenger compartment to be positioned in multiple orientations based on the occupant's preference, with a control device detecting the occupant's position to adjust the compartment's configuration, and transparent wheel rims for enhanced visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the vehicle body and passenger compartment are made rotatable relative to the chassis and seat device, then the adaptability and versatility of seating positions are improved, but the device complexity increases due to multiple rotation mechanisms
Solution Approach 1:
The patent combines multiple rotation functions into a unified mechanism where the passenger compartment rotates relative to the seat device, and the seat device rotates relative to the chassis about the same vehicle axle axis. This merging of rotation centers simplifies the overall mechanism compared to having separate rotation joints, while still achieving the capability for multiple seating configurations including standing, sitting, and zero-gravity positions.
Solution Approach 2:
The rotation mechanism serves multiple functions: it enables the passenger compartment to be oriented in different basic positions (horizontal for sitting, vertical for standing), allows the seat device to independently rotate for seating adjustments, and facilitates transitions between various occupant positions. This multi-functionality reduces the need for separate mechanisms for each adjustment type.
2Ease of operation
If the passenger compartment is made rotatable about the vehicle axle, then the ease of operation for position adjustment is improved, but the stability of the vehicle body composition worsens due to additional moving joints
Solution Approach 1:
The patent implements dynamic adjustability where the passenger compartment and seat device can rotate relative to each other and the chassis, allowing the vehicle to adapt its configuration based on operational needs. The system transitions from a static rigid structure to a dynamic reconfigurable structure, enabling easy position adjustments while maintaining stability through controlled rotation about the vehicle axle.

AI summary
A motor vehicle having a vehicle body with a passenger compartment, a chassis supporting the vehicle body, a vehicle axle which can be driven by a drive device, and a seat device which is arranged inside the passenger compartment and is rotatable relative to the passenger compartment about an axis of rotation. The chassis supporting the vehicle body has only one vehicle axle, about the axis of which, the vehicle body with the passenger compartment and the seat device arranged inside the passenger compartment are rotatable relative to each other.
