Sealed Fastening Member for Removable Accessory Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for fixing sheets to structures compromise air and water tightness and structural integrity when attempting to attach accessories, as they require additional screws or modifications that disrupt the sealing and strength of the sheet's attachment.
Innovation Solution
A fastening member with a threaded rod and collar system allows for a sealed, definitive attachment of the sheet to a structure while enabling the removable attachment of accessories without interfering with the sheet's sealing or structural integrity, using a self-drilling tip and a sealed bearing collar for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bearing and sealing washer is used to fix the sheet to the structure, then the sheet is securely attached to the structure, but it becomes impossible to attach an accessory to the sheet without drilling additional holes that compromise tightness and structural integrity
Solution Approach 1:
The invention divides the fastening function into two separate components: the bearing and sealing washer remain fixed on the sheet to maintain structural attachment, while a separate threaded rod is inserted through the washer to provide accessory mounting capability. This segmentation allows each component to fulfill its specific function without interfering with the other.
Solution Approach 2:
The threaded rod acts as an intermediary element that passes through the bearing and sealing washer assembly. It provides a threaded surface for accessory attachment while not interfering with the washer's sealing function against the sheet, thus mediating between structural fixation and accessory mounting requirements.
2Ease of operation
If another screw is installed to attach an accessory to the sheet, then the accessory can be fixed, but the sheet's tightness and structural integrity are compromised due to additional drilling
Solution Approach 1:
The bearing and sealing washer assembly is designed to serve multiple functions simultaneously: it provides structural attachment to the sheet, maintains sealing integrity, and incorporates a threaded rod that enables accessory mounting. This multi-functionality eliminates the need for separate fastening operations.
Solution Approach 2:
The threaded rod is预先 installed as part of the bearing and sealing washer assembly during the initial sheet attachment process. This preliminary action ensures that the accessory mounting capability is already in place before accessory installation, avoiding subsequent drilling operations that would compromise sheet integrity.
3Reliability
If the sheet is fixed definitively to the structure, then air and water tightness is ensured, but the ability to modify or adjust the setup is reduced
Solution Approach 1:
The invention creates a dynamic fastening system where the bearing and sealing washer provide definitive structural attachment for tightness, while the threaded rod and accessory assembly can be independently adjusted, removed, or modified. This dynamic design allows the system to maintain sealing integrity while accommodating future modifications or repairs.

AI summary
The invention relates to an attachment member (1) including a first threaded portion (3) suitable for ensuring the attachment of a mounting (19) onto a structure, a means (5, 15) for sealing the attachment of the mounting onto the structure, and a second portion (6) suitable for moving the first portion (3) while locking the sealing means in engagement with the mounting (19). The sealing means includes a bearing flange (5) in the shape of a flattened ring, which is at least translatably immobile in a direction parallel to a longitudinal axis (D) of the first portion (3), which is suitable for maintaining the accessory, by means of clamping, between a clamping member (10) and the second portion (6), which is positioned on one end of the first portion (3), which causes the separation between the first portion (3) and the second portion (6), and from a surface (50) of which the second portion extends toward a free end (7) of the member. A radial groove (8) for receiving and holding an accessory (24) is provided on one end (70) of the second portion, said groove adjoining said surface of the bearing flange.
