Smartphone Holder Dual Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smartphone holders for shopping carts lack effective mechanisms to securely fasten and lock smartphones, allowing for unauthorized removal and requiring complex handling processes.
Innovation Solution
A smartphone holder with a dual locking system, including a form-locking mechanism and an authorization check using a token with a transponder, which ensures secure fastening to the shopping cart handle, allowing simultaneous locking and unlocking of both mechanisms with a slider or switch, facilitating easy handling and preventing unauthorized removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dual locking system with authorization check is implemented, then security against unauthorized removal is improved, but device complexity increases
Solution Approach 1:
The patent combines the smartphone locking mechanism and the holder fastening mechanism into a unified dual locking system. Both functions share common components including the slider actuator, authorization check mechanism, and locking geometry. The first locking mechanism uses the slider to move a locking element between locked and unlocked positions for the smartphone, while the second locking mechanism uses the same slider movement to engage or disengage the holder from the shopping cart handle, thereby securing both functions through a single integrated system.
Solution Approach 2:
The slider mechanism serves multiple functions simultaneously: it acts as an authorization interface, a release actuator for the smartphone locking mechanism, and a fastening actuator for the holder mounting mechanism. The authorization check system also serves dual purposes by verifying user credentials and controlling access to both locking mechanisms. This multi-functionality reduces the number of separate components needed while maintaining security.
2Ease of operation
If simultaneous locking of smartphone and holder is enabled, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent merges the control functions for smartphone locking and holder fastening into a single slider mechanism. When the user moves the slider from the first position to the second position, both the first locking mechanism (smartphone lock) and the second locking mechanism (holder fasten) are activated simultaneously through shared mechanical linkages and common actuation points.
Solution Approach 2:
The authorization check is performed in advance before the locking action is executed. The system verifies the user's credentials through the slider interface before enabling the locking mechanisms, ensuring that only authorized users can lock the smartphone or fasten the holder. This preliminary verification simplifies the user interaction flow by combining authentication and locking into a single atomic operation.
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 dual locking system provides enhanced security by ensuring the smartphone and holder are locked only after authorization, allowing flexible locking options and preventing unauthorized removal, while simplifying the handling process for users.
Implementation Method 1
it preferably has a transponder, by means of which an electronic authorization check is executed in the holder

AI summary
A method for detachably fastening a smartphone holder to a shopping cart includes a first and a second step. In the first step, a smartphone is placed on a seating of the holder. In a second step, the smartphone is locked in the seating. The locking of the smartphone in the seating activates a locking mechanism which automatically locks the holder, which is inserted in a seating provided for that purpose on the shopping cart, in the seating.
