Pivotable Cantilever Fastening for Vehicle Cabin Fitments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening systems for vehicle cabin fitments are inflexible, requiring alignment with a predetermined grid on the floor, limiting the ability to change seat spacings and relocate fitments without adapting the fitment's dimensions.
Innovation Solution
A fastening system featuring a pivotable cantilever with a first fastening element and multiple second fastening elements, allowing for variable positioning and secure locking, enabling flexible fastening of fitments without being constrained by the grid layout.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a grid-based fastening system is used in the vehicle cabin floor, then fastening elements can be positioned at regular intervals, but the fitment location and orientation are constrained by the grid layout
Solution Approach 1:
The patent employs a dynamic cantilever mechanism that can be manually positioned and locked at various angles relative to the vehicle floor. This dynamic positioning capability allows the fitment to be oriented in multiple directions and locations without being constrained by a fixed grid pattern, thereby resolving the contradiction between ease of installation and flexibility of positioning
Solution Approach 2:
The system allows changing the orientation parameter of the cantilever from fixed to variable, enabling it to assume multiple angular positions. This parameter change transforms the fastening system from a rigid grid-based structure to a flexible positioning system that can adapt to different fitment requirements while maintaining simple installation procedures
2Ease of operation
If the fitment is fixed to align with the grid pattern, then installation is simplified, but the ability to change seat spacings and relocate fitments is limited
Solution Approach 1:
The cantilever's manual positioning and locking mechanism provides dynamic adaptability, allowing the fitment to be relocated to different positions and orientations along the vehicle floor without requiring changes to the underlying fastening infrastructure. This maintains installation simplicity while enabling flexible relocatability
Solution Approach 2:
The fastening system serves multiple functions: it provides both fixed grid-based attachment points and flexible variable-position attachment through the cantilever mechanism. This multi-functionality allows the same system to accommodate both simplified installation procedures and flexible fitment relocation requirements
3Stability of the object's composition
If a rigid fastening system is used, then structural stability is ensured, but flexibility in positioning and orienting fitments is reduced
Solution Approach 1:
The system combines rigid structural elements (the cantilever and locking mechanism) with dynamic positioning capability. The rigid components ensure structural stability when locked, while the ability to manually reposition and relock provides positioning flexibility, resolving the contradiction between stability and adaptability

AI summary
A fastening system for fastening fitments to a floor of a cabin of a vehicle has a receiving frame, a cantilever mounted on the receiving frame so as to be pivotable on a pivoting plane defined by the receiving frame, and having a mounting end and a fastening end, a first fastening element, and a multiplicity of second fastening elements. The first fastening element is arranged at the fastening end of the cantilever. The second fastening elements are positionable on the floor. The first fastening element is configured in a manner corresponding to the second fastening elements such that the first fastening element is mechanically connectable selectively to a second fastening element. A pivoting position of the cantilever is lockable relative to the receiving frame.
