Integral Fastening Section for Sterile Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing steril container attachment solutions require multiple components and steps, often damaging the container shell and allowing contamination, and are complex to install or replace.
Innovation Solution
A container system with an integral fastening section formed from the container wall, using deformable fastening members that create a secure, tool-free connection without additional components, ensuring the sterile barrier remains intact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If attachments are riveted to the container body, then the attachment is securely fixed, but the container shell is damaged and requires permanent sealing
Solution Approach 1:
The fastening section is formed integrally with the container wall as a single piece, eliminating the need for separate attachment components like rivets. This merging of the fastening function into the container wall itself provides secure attachment while avoiding shell damage from penetration or perforation.
Solution Approach 2:
The fastening section acts as an intermediary element between the container wall and the attachment. It provides a dedicated interface for attachment while maintaining the integrity of the container wall, serving as a mediator that enables secure fastening without direct damage to the shell.
2Reliability
If multiple components are used for fastening, then the attachment can be securely fixed, but the device complexity increases and sterilizability decreases
Solution Approach 1:
The fastening section is integrated directly into the container wall as an integral part, eliminating the need for separate brackets, clips, or other intermediate fastening components. This single-piece design reduces complexity while maintaining secure attachment capability through the integral fastening geometry.
3Ease of operation
If holes are created in the container wall for attachment, then the attachment can be installed, but the sterile barrier integrity is compromised
Solution Approach 1:
The fastening section creates a localized feature on the container wall surface that provides attachment capability without penetrating through the wall. The local modification is confined to the outer surface layer, preserving the integrity of the sterile barrier while enabling attachment installation.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Simplifies attachment and removal processes, reduces contamination risk, and maintains the integrity of the sterile barrier by eliminating the need for additional components and complex installation steps.
Implementation Method 1
a fastening member (22) which can be transferred from a fastening position, in which it is designed to exert a securing engagement with the corresponding fastening section (12), into a deflected position, in which the fastening member (22) is deflected and/or deformed for transfer into or out of the securing engagement with the fastening section (12)
