Pop-Up Tractor Trailer Sleeper with Dynamic Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tractor-trailer trucks often lack spacious and luxurious living quarters, making them unsuitable for long haul travel, and their large berthing areas complicate maneuverability in tight spaces.
Innovation Solution
A pop-up living area for tractor-trailer trucks featuring a lower housing with a bed, kitchenette, self-contained toilet, and emergency escape hatch, supported by vertical beams and operated by linear actuators, allowing for easy access and emergency egress, and designed to be compact enough to pass under standard overpasses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a large berthing area is provided in the tractor trailer truck, then the living comfort is improved, but the wheelbase becomes longer making maneuverability more difficult
Solution Approach 1:
The living quarters are designed as a dynamic structure that can be raised and lowered. When lowered, the wheelbase remains short for easy maneuverability. When raised, the living quarters expand to provide a spacious berthing area. This dynamic configuration allows the same structure to satisfy both contradictory requirements at different operational states.
Solution Approach 2:
Instead of expanding the living quarters horizontally (which would increase wheelbase), the invention utilizes the vertical dimension by raising and lowering the living quarters relative to the truck body. This dimensional transition allows spacious accommodation without increasing the horizontal footprint or wheelbase length.
2Volume of moving object
If a large berthing area is provided in the tractor trailer truck, then the living comfort is improved, but the device complexity increases
Solution Approach 1:
The living quarters are divided into separate modular components: an upper housing containing the berthing area, a lower housing containing amenities, and a support structure. This segmentation allows each module to be independently manufactured, assembled, and maintained, reducing overall system complexity while providing a large total volume.
Solution Approach 2:
The support beams serve multiple functions: they structurally support the upper housing, provide mounting points for linear operators, and act as structural connectors between the floor and front bumper area. This multi-functionality reduces the number of separate components needed, thereby reducing device complexity.
3Length of moving object
If the upper housing is made compact to pass under overpasses, then the maneuverability is improved, but the living space is reduced
Solution Approach 1:
The upper housing dynamically changes its vertical position. When passing under overpasses, it is lowered to a compact profile. When parked, it is raised to provide full living space volume. This dynamic adjustment allows the same structure to satisfy both compact transit requirements and spacious living requirements at different times.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Provides a comfortable, luxurious, and functional living space that is easily accessible and maneuverable, incorporating essential amenities like a full-size bed, kitchen, and toilet, while maintaining a compact profile to facilitate easy movement.
Implementation Method 1
at least four linear operators raising and lowering the upper housing from the lower housing
Implementation Method 2
The piping may include a plurality of electric heat tracing to avoid freezing in cold climate operation
