Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sleeper vehicles face challenges in finding a level surface to park on, leading to potential health issues due to uneven sleeping surfaces, with existing solutions being cumbersome, unsafe, or cost-prohibitive.
Innovation Solution
A self-leveling sleep surface frame with telescoping beams, bi-directional joints, and linear actuators, controlled by a controller unit, adjusts to create a level sleeping surface within the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire sleeper vehicle is leveled using traditional methods, then the sleeping surface becomes level, but the process becomes cumbersome and requires extensive user effort
Solution Approach 1:
The invention segments the leveling function from the entire vehicle to just the sleep surface frame. Instead of leveling the whole vehicle, only the sleep surface frame is equipped with adjustable legs that can be independently positioned to achieve leveling, significantly reducing the complexity and user effort required.
Solution Approach 2:
The sleep surface frame performs its own leveling function through integrated adjustable legs and level indicators, without requiring external equipment or extensive user intervention. The system is self-contained and can be adjusted by the user through simple operations.
2Reliability
If traditional leveling solutions are used, then leveling can be achieved, but the solutions are either not effective or too cumbersome for users
Solution Approach 1:
The leveling system is segmented into simple, discrete components: adjustable legs at each corner of the sleep surface frame and visual level indicators. This segmentation avoids complex mechanical or electronic systems while achieving effective leveling through simple height adjustments at each corner.
3Reliability
If cost-prohibitive solutions are implemented for vehicle leveling, then effective leveling is achieved, but the cost becomes prohibitive for many users
Solution Approach 1:
The invention uses simple, inexpensive components such as adjustable legs with basic height mechanisms and visual level indicators (like bubble levels or spirit levels). These components are far cheaper than electronic sensor systems or hydraulic leveling systems, making the solution accessible to a wide range of users.
4Manufacturing precision
If the sleep surface frame is made fully adjustable for leveling, then leveling precision is improved, but the structural stability may be compromised
Solution Approach 1:
The sleep surface frame incorporates dynamic adjustable legs that can be modified in height to compensate for uneven ground. The adjustability is implemented through simple mechanical means (such as threaded rods or telescopic sections) that maintain structural integrity while allowing precise height adjustments at each corner to achieve a level sleeping surface.

AI summary
A self-leveling sleep surface frame includes linear actuators at each corner of a sleep surface frame connected by bi-directional joints to a plurality of telescoping beams which allows for the length of the beams to change and the angle of the connections between the beams and joints to adjust while achieving a level position for the sleep surface frame when a sleeper vehicle is on an unlevel surface.
