Telescopic Vehicle Cabin Sliding Segment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing building and vehicle structural designs for expanding interior space suffer from high friction losses and inadequate stability, while also lacking effective sealing mechanisms.
Innovation Solution
The structural design incorporates guides aligned at right angles on the walls of sliding segments with alternating edge lengths, forming intermediate sealing lips for low friction and high stability, along with a guide rail and carriage system for minimal friction loss, and allows sliding segments to telescope for maximum usable space creation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sliding segments are mounted to be displaceable in multiple directions to expand interior space, then the usable space is increased, but friction losses increase and stability decreases
Solution Approach 1:
The patent implements a nested telescopic structure where sliding segments are arranged in three groups (first group slides in second group, second group slides in third group). This nesting allows multiple segments to displace relative to each other in multiple directions while maintaining compact configuration when retracted, expanding usable space without proportionally increasing friction losses since only outer segments need active driving mechanisms.
Solution Approach 2:
The structure is divided into three distinct groups of sliding segments, each with specific displacement capabilities. The first group slides in a first direction, the second group slides in a second direction perpendicular to the first, and the third group provides engagement between the other two groups. This segmentation distributes the displacement functions across separate components, reducing the friction burden on any single segment while achieving multi-directional expansion.
2Adaptability or versatility
If sliding segments are mounted to be displaceable in multiple directions to expand interior space, then the usable space is increased, but stability decreases
Solution Approach 1:
Different groups of sliding segments are assigned different functional qualities: the first group provides displacement in the first direction, the second group provides displacement in the perpendicular second direction, and the third group specifically provides engagement and stabilization between the first and second groups. This local differentiation of functions ensures that stability is maintained in areas where multi-directional movement occurs.
Solution Approach 2:
The third group of sliding segments acts as an intermediary engagement mechanism between the first and second groups. These segments physically connect and coordinate the movements of the first and second groups, ensuring that displacements in multiple directions occur in a coordinated manner that maintains overall structural stability rather than creating conflicting forces.
3Adaptability or versatility
If sliding segments are mounted to be displaceable in multiple directions to expand interior space, then the usable space is increased, but sealing becomes inadequate
Solution Approach 1:
Sealing lips are pre-formed on the sliding segments before operation. These sealing lips are integrated into the structure of each sliding segment and are positioned to automatically engage with adjacent segments during displacement. The preliminary formation of sealing surfaces ensures that sealing action occurs continuously throughout the displacement range, maintaining reliability even as the structure expands and contracts.

AI summary
In a building structure ideally suited for connection to a vehicle (103), for example in the form of a living cabin (115), the sliding segments include a number of horizontal sliding segments (201) movable in an expansion direction, vertical sliding segments (136) movable in an extension direction perpendicular to the expansion direction, and double sliding segments (139) movable in both the expansion and extension directions, all connected to a central fixed segment (403). This allows the interior space of the building structure (115) to be significantly increased by one usable space when the sliding segments (136, 139, 201) are moved from a retracted compact position to an extended expansion position, compared to the minimum volume in the compact position.
