Mobile Airbag Bracket with Elastic Cover and Magnetic Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile airbag brackets with rigid plastic ends cause discomfort during long-term use and have fixed decorative covers that are difficult to remove and increase product size, making them less portable.
Innovation Solution
A mobile airbag bracket structure featuring a protruding circular base on the airbag that fits into a groove with a card slot on an elastic decorative cover, allowing for easy assembly and quick removal or replacement of the cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a decorative cover is added to the airbag bracket, then the contact area with fingers increases and comfort improves, but the overall size of the product increases and portability decreases
Solution Approach 1:
The airbag is folded and stored inside the decorative cover when not in use, similar to a nested doll structure. This allows the decorative cover to serve dual purposes: as a protective case and as a storage container for the airbag, thereby not increasing the overall product volume while still providing grip comfort when deployed.
Solution Approach 2:
The airbag transitions from a folded state inside the cover to an expanded state during use. This dynamic transformation allows the product to maintain a compact size when stored while providing the necessary functional expansion when needed, resolving the contradiction between size and functionality.
2Stability of the object's composition
If adhesive is used to fix the decorative cover to the airbag bracket, then the cover remains securely attached, but it cannot be removed or replaced during use
Solution Approach 1:
The connection between the airbag and decorative cover is segmented into discrete magnetic components: a magnetic component in the airbag and another in the cover. This segmentation allows the cover to be easily attached and detached without adhesive, enabling replacement while maintaining secure attachment during use through magnetic force.
Solution Approach 2:
The adhesive bonding mechanism is replaced with a magnetic field-based attachment system. This substitution eliminates the permanent bonding of adhesive while providing sufficient holding force through magnetic attraction, allowing the cover to be securely attached yet easily removed and replaced.
3Reliability
If the decorative cover is fixed with adhesive, then it remains attached during use, but it cannot be removed for storage or replacement
Solution Approach 1:
Adhesive bonding is replaced with magnetic attachment, providing reliable holding force during use while enabling easy removal. The magnetic force maintains secure attachment under normal conditions but allows simple detachment when needed, satisfying both reliability and ease of operation requirements.
Solution Approach 2:
The attachment mechanism transitions from a permanent chemical bond (adhesive) to a controllable physical force (magnetic field). This parameter change allows the attachment strength to be easily overridden by applying slight manual force for removal, while maintaining strong attachment during normal use, thus achieving both reliability and removability.

AI summary
A mobile airbag bracket structure includes a main part including an airbag and a decorative cover. One end of the airbag is provided with a circular base protruding from the bottom of the airbag. The surface of the decorative cover is equipped with a groove having a sidewall of the groove provided with a card slot. The diameter of the base is greater than the opening diameter of the groove. The thickness of the base is smaller than or equal to the depth of the card slot. The airbag is installed in the groove of the decorative cover through the base. The base is inserted into the card slot on the sidewall of the groove to fasten the airbag.
