Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening systems for components in vehicle cabins face challenges in compensating for component-related and manufacturing-related tolerances, leading to complex assembly processes.
Innovation Solution
A fastening system comprising a first longitudinal beam with adjustable support elements forming a triangular shape, allowing for tolerance compensation through adjustable mounting positions and lengths, forming a rigid truss-like structure with multiple beams for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If fixed-length connecting rods are used to attach components in the cabin, then the structural stability is improved, but the ability to compensate for tolerances deteriorates
Solution Approach 1:
The connecting rod incorporates an adjustable length mechanism that allows the rod to be modified during assembly or operation. This dynamic adjustment capability enables the rod to accommodate tolerance variations in the cabin structure while maintaining structural stability, resolving the contradiction between fixed geometry and adaptability.
Solution Approach 2:
The length parameter of the connecting rod is made variable through adjustment mechanisms such as threaded sections, telescopic design, or interchangeable inserts. By changing the length parameter, the system can compensate for manufacturing and installation tolerances without compromising the structural integrity provided by the rigid rod design.
2Adaptability or versatility
If adjustable support elements are used to compensate for tolerances, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The connecting rod is divided into modular segments that can be independently adjusted or replaced. This segmentation allows for simple length adjustments by adding or removing standardised sections, reducing assembly complexity while maintaining high adaptability to tolerance variations.
Solution Approach 2:
A simple intermediary mechanism such as a threaded adjuster, telescopic section, or standardized insert is introduced into the connecting rod. This intermediary element provides the adjustment functionality with minimal complexity, enabling tolerance compensation through straightforward mechanical means without requiring complex systems.

AI summary
A fastening system for securing a component in a cabin is proposed, comprising a first longitudinal beam (12), at least two pairs (14, 16) of two support elements (20), and several structural connectors (18), wherein the pairs of support elements can be connected to the longitudinal beam and the structure such that they extend triangularly between the first longitudinal beam and the structure, wherein two ends (22) of the support elements of each pair are spaced apart from each other and the support elements converge from these ends, wherein the longitudinal beam has at least one first fastening unit for connecting each support element to the longitudinal beam, wherein the support elements of each pair can be connected to the structure by means of at least one of the structural connectors.and wherein the length of at least one of the support elements of each pair is adjustable and/or at least one first fastening element is arranged on the longitudinal beam at an adjustable fastening position, such that the pair of support elements in question can assume an adjustable triangular shape to bridge a tolerance gap formed between the longitudinal beam in question and the structure.
