Mobile Phone Holder with Bistable Spring Loop for Air Vent Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile phone holders for car dashboards are prone to wear and tear from extreme temperatures, are not portable, and can cause sudden ejection of the phone due to lack of a secure attachment mechanism, leading to driver distraction and potential accidents.
Innovation Solution
A mobile phone holder that creates a closed loop around air vent bars using a bistable spring or strap attached to the phone, providing a secure and portable mounting solution that is not exposed to extreme temperatures and includes a handle and stand for easy use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnetic phone holders are used, then the phone can be mounted to the dashboard, but the strong shakes in the car can cause the phone to be detached from the magnet
Solution Approach 1:
The phone holder is divided into two separate components: a clamp mechanism that attaches to the air vent and provides stable mechanical support, and a magnetic component that attaches the phone to the clamp. This segmentation allows each component to perform its specialized function optimally.
Solution Approach 2:
The invention combines two different attachment mechanisms (clamp and magnet) into a single integrated system. The clamp provides stable mounting to the air vent while the magnet provides secure attachment to the phone, merging the advantages of both mechanisms.
2Reliability
If clamp-like phone holders are used, then the phone can be held firmly, but if protective covers or card wallets are used on the phone, the thickness increases and the holder won't be able to hold the phone firmly
Solution Approach 1:
The invention replaces the direct mechanical clamping system with a magnetic attachment system. The magnet can attract and hold the phone (or its protective cover/wallet) without requiring direct contact with the phone's edges, thus accommodating variations in phone thickness while maintaining secure holding.
3Ease of manufacture
If rubber or plastic parts are used in the phone holder, then the holder can be attached to the dashboard, but the extreme temperature in the car causes damage to these parts
Solution Approach 1:
The invention changes the material parameters of the clamp from temperature-sensitive rubber or plastic to temperature-resistant metal. This parameter change allows the holder to maintain its mechanical properties and attachment capability under extreme temperature conditions while the magnetic component handles the phone attachment function.
4Reliability
If the phone holder is not portable and stays in the car, then it provides stable mounting, but when the user has a temporary or rental car, it will not be possible to mount the phone unless the user carries all parts of the holder
Solution Approach 1:
The phone holder is segmented into a permanent clamp component that remains in the car for stable mounting, and a removable magnetic component that attaches to the phone and can be easily carried by the user. This segmentation enables both stable mounting when in use and easy portability when transferring between vehicles.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution prevents sudden phone detachment and reduces wear and tear, ensuring the phone remains securely attached during car movements, is easily portable between vehicles, and reduces the risk of accidents by maintaining phone visibility and accessibility.

AI summary
A mobile phone holder is disclosed for mounting a mobile phone to the dashboard of a car. This mobile phone holder is integrated into the back of a mobile phone or is attached to the back surface of the mobile phone through adhesive pads, or suction cups, or is incorporated into accessories of mobile phones such as attachable card holding wallets, and etc. One embodiment of this mobile phone holder creates a closed loop around the air vent bars. Hence, shakes of the car will not cause sudden detachment and falling of the phone. In Addition, this mobile phone holder is portable and is carried by the mobile phone. Hence, the user can readily have it upon using a temporary car. Moreover, since this mobile phone holder is not permanently stayed in the car, it is not exposed to extreme temperatures and thus its wear and tear is lower than conventional phone holders. The loop that is formed by this apparatus can also be used for mounting a mobile phone to the handlebar of a shopping cart, the handlebar of a bike, safety belt of a car, a belt loop, belt of a user, strap of a bag, or other accessories of a user. This apparatus can also be used as a general purpose fastener for fastening two or more objects together, hanging objects from a bar. Such general purpose fastener can be used as a toy, strap of a watch, or bracelet as well.
