Elevated RV Driving Compartment Visibility Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional recreational vehicles have limited visibility for rear passengers, increased risk of unsecured objects causing injury during crashes, and poor navigation due to the same-level driving and living compartments, which complicates parking and collision avoidance.
Innovation Solution
The recreational vehicle design features a driving compartment elevated above the living compartment, with all seats in the driving area equipped with safety belts, providing an unobstructed view for occupants and ensuring that unsecured objects are projected below the driving compartment during collisions, thus enhancing safety and visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the driving compartment is at the same level as the living compartment, then the structure is simple and easy to manufacture, but unsecured objects may be projected from the living area into the driving area during a crash, causing danger to occupants
Solution Approach 1:
The patent applies vertical dimensionality change by elevating the driving compartment above the living compartment. This creates a height difference that prevents unsecured objects in the living area from being projected into the driving area during crashes, thereby improving occupant safety without significantly complicating the overall vehicle structure.
2Volume of moving object
If the roofline is far above the driver's head, then the vehicle has sufficient headroom for living space, but the driver has poor visibility and difficulty estimating vehicle height, making navigation and parking difficult
Solution Approach 1:
The patent resolves this contradiction by utilizing the vertical dimension to separate the driving compartment elevation from the overall vehicle roof height. The driving compartment is positioned at an elevated level with its own roof, providing both sufficient headroom for the living space below and optimal visibility for the driver at the elevated position, while maintaining accurate height estimation for navigation.
Solution Approach 2:
The vehicle structure is segmented into distinct elevation levels: the living compartment at a lower level and the driving compartment at an elevated level. This segmentation allows each zone to be optimized independently - the lower level provides headroom volume while the elevated driving position provides visibility and navigation control.
3Adaptability or versatility
If rear passenger seats are located in the living area, then the living space can serve multiple functions, but rear passengers are distant from the driver and front passenger, making conversation difficult
Solution Approach 1:
The patent merges the rear passenger seating function with the driving compartment by positioning rear passenger seats in the elevated driving area rather than in the living compartment. This combines the social/communication function with the driving function, allowing all occupants to be in close proximity for conversation while the living area maintains its multifunctional capabilities.

AI summary
A recreational vehicle is described, which comprises a living department and a driving department. The driving department is elevated above the living department, providing windows to all sides for driver and passengers to enjoy surround view while travelling. The driving compartment comprises sufficient seats for all occupants of the recreational vehicle while travelling. Seats in the living compartment are not used while driving.
