Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening systems for monuments and overhead storage bins in vehicles, such as aircraft, are not efficient in providing a stable and flexible attachment that allows for easy and reliable mounting, particularly in constrained spaces with varying tolerances and loads.
Innovation Solution
A modular fastening structure comprising modules with adjustable struts and spacer elements that allow for variable positioning and alignment, providing tolerance compensation and uniform load distribution, suitable for attaching both monuments and overhead storage bins to vehicle attachment structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed and rigid fastening structure is used to securely attach monuments and overhead storage bins, then the reliability and stability of attachment are improved, but the ability to accommodate varying tolerances and flexible arrangement is worsened
Solution Approach 1:
The fastening structure employs adjustable struts that can be varied in length and positioned at different angles, transforming a static rigid structure into a dynamic adaptable one. This allows the structure to accommodate varying tolerances while maintaining secure attachment through lockable positions.
Solution Approach 2:
The fastening structure is divided into modular components including first and second modules for different attachments, spacer modules, and adjustable struts. This segmentation allows independent adjustment of each component to achieve both stability and flexible arrangement configurations.
2Reliability
If multiple separate fastening systems are used for monuments and overhead storage bins, then the reliability of each attachment is improved, but the device complexity and space requirement are worsened
Solution Approach 1:
The patent combines the fastening systems for monuments and overhead storage bins into a single integrated modular structure. The first and second modules share common struts and spacing mechanisms, reducing overall complexity while maintaining reliable attachment for both components through unified design.
Solution Approach 2:
The modular fastening structure is designed with universal components that can serve multiple functions. The adjustable struts and spacer modules can accommodate different attachment types and configurations, allowing the same structural elements to reliably secure both monuments and overhead storage bins without requiring separate dedicated systems.
3Adaptability or versatility
If adjustable and variable positioning mechanisms are added to accommodate tolerances, then the adaptability and alignment are improved, but the device complexity is worsened
Solution Approach 1:
The fastening structure utilizes adjustable struts where key parameters such as length and angle can be changed to compensate for tolerances. By providing multiple possible positions and lockable configurations, the system achieves adaptability through parameter variation rather than complex mechanisms.
Solution Approach 2:
Adjustability and tolerance compensation features are applied locally at specific connection points rather than throughout the entire structure. The struts can be adjusted at their connection points to first and second positions, providing localized adaptation that simplifies the overall structure compared to making the entire system adjustable.

AI summary
In order to allow a monument and an overhead storage bin to be mounted on a vehicle the invention proposes a fastening structure (3) which is mountable on an attachment structure (2) of an interior of a vehicle (100) and which comprises at last one first module (10) for the monument, at least one second module (10) for the overhead storage bin and a spacer module (40) arranged between the first module (10) and the second module (10). The first module (10) and the second module (10) each comprise an elongate body (17), a first strut (19) detachably coupled between the elongate body (17) and a first fastening (20) for fastening the module (10) to the attachment structure (2) and a second strut (21) that is detachably coupled between the elongate body (17) and the first fastening (20) and that extends at an inclined angle to the elongate body (17). The spacer module (40) comprises an elongate spacer body (41), a first elongate interface strut (42) having a second fastening for fastening the spacer module (40) to the attachment structure (2) and a second interface strut (43) having a third fastening for fastening the spacer module (40) to the attachment structure (2). The elongate spacer body (41) is detachably coupled by a third strut (52) to the first interface strut (42) at a first joint (53) intermediate the length of the first interface strut (42) and is detachably coupled by a fourth strut (54) to the second interface strut (43) at a second joint (55) intermediate the length of the second interface strut (43).
