Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle slide-out systems are bulky, complex to install, and costly, occupying substantial space and requiring dismantling of the vehicle chassis for installation.
Innovation Solution
A spiral vehicle box slide-out system with a slide-out box, spiral movement component, driving device, and support frame integrally mounted on the vehicle's lower part, allowing easy installation and removal without dismantling the chassis, and reducing space occupation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If traditional slide-out mechanisms are used, then the slide-out box can extend outward to increase usable space, but the mechanism occupies substantial space and is complex to install
Solution Approach 1:
The patent integrates the driving device, support frame, and slide-out box into a unified structure where the driving device is mounted directly on the support frame, which is integrally connected to the box. This merging eliminates the need for separate mounting components and simplifies installation to merely fixing the support frame's bottom plate to the vehicle body.
Solution Approach 2:
The support frame serves multiple functions: it supports the driving device, provides structural connection to the slide-out box, and its bottom plate serves as the mounting interface to the vehicle body. This multi-functionality reduces the number of separate components needed and simplifies the overall installation process.
2Length of moving object
If complex high extension drive devices are used, then the slide-out box can extend, but the device occupies considerable space and increases maintenance cost
Solution Approach 1:
The system is segmented into distinct functional modules: the driving device with motor and transmission, the support frame providing structural support, and the slide-out box. This segmentation allows for easier maintenance as components can be accessed and replaced independently, reducing maintenance costs and complexity.
Solution Approach 2:
The bearing box serves as an intermediary structure that houses and protects the driving device components, providing a maintenance-friendly enclosure that allows access to internal components while protecting them from external elements.
3Force
If slide-out mechanism is located beneath the vehicle body, then it can support the box, but it lacks integrated design and occupies substantial space
Solution Approach 1:
The support frame is integrally connected to the slide-out box, merging the support function with the box structure itself. This integration eliminates the need for separate underlying support structures, reducing space occupation while maintaining support capacity.
Solution Approach 2:
The support function is achieved through vertical integration (the support frame extending downward from the box) rather than horizontal expansion, allowing the mechanism to be compact in the horizontal plane while providing adequate support structure vertically.
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
Facilitates easy installation and removal, enhances interior space utilization, and reduces maintenance costs by integrating components within the bearing box, providing an aesthetically pleasing appearance and reliable operation.
Implementation Method 1
a spiral movement component (30), a driving device (34)... The spiral movement component (30) is fixed on the support frame (3)... The large gear (12) is provided at the end of the ball screw (5) near the first bearing (18a), and the ball screw (5) moves spirally within the ball nut (6)

AI summary
The present application relates to a spiral vehicle compartment slide-out system, which includes a spiral movement component, a drive device, support frame, and a bearing box. These components are integrally arranged inside the bearing boxes located on the lower part of the box on both sides. There is no need to disassemble the vehicle's chassis; instead, by simply fixing the support frame to the vehicle body, the slide-out compartment can be positioned at the opening of the vehicle body. This application enables the sliding out of the vehicle compartment, increasing usable space, and offers convenient installation and removal, as well as neatness and aesthetic appeal.
