Removable Payment Element in Mobile ID Transmitter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile ID transmitters for motor vehicles lack enhanced functionality and convenience, particularly in integrating payment features while ensuring secure keyless activation and protection against unauthorized use.
Innovation Solution
A mobile ID transmitter with a removable payment element and emergency key handle, featuring a communication interface for both vehicle and payment systems, allowing cashless transactions and secure keyless vehicle access, while ensuring the payment element can be easily removed for security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mobile ID transmitter is designed with only vehicle access functionality, then the device remains simple, but the functionality and versatility are limited
Solution Approach 1:
The mobile ID transmitter is designed to perform multiple functions: vehicle access control (keyless entry/exit and trunk release) and electronic payment transactions. The single device integrates both a data unit for vehicle authentication and a removable payment element for cashless payments, eliminating the need for separate key fob and payment card
Solution Approach 2:
The patent combines two previously separate devices (vehicle key fob and payment card) into a single integrated mobile ID transmitter. The housing contains both the fixed data unit for vehicle access and the removable payment element, merging vehicle control and payment functions into one portable device
2Reliability
If payment element is permanently integrated in the housing, then the device structure is simplified, but the security against unauthorized use is reduced
Solution Approach 1:
The mobile ID transmitter is divided into distinct segments: a fixed housing with data unit and a removable payment element. The payment element can be detached from the housing, allowing the user to separate the payment function from the vehicle access function, thereby enhancing security control
Solution Approach 2:
The payment element's connection to the housing is designed to be dynamically changeable - it can be inserted into and removed from the receptacle in the housing. This dynamic configuration allows the user to adapt the device setup based on security requirements and usage scenarios
3Ease of operation
If multiple functions are integrated in one device, then convenience is improved, but the risk of unauthorized access increases
Solution Approach 1:
By segmenting the device into a fixed housing (with vehicle access data unit) and a removable payment element, the user can physically separate the payment function from the vehicle control function. This prevents unauthorized persons from using the entire device for both functions if they only obtain one part
Solution Approach 2:
The payment element is extracted as a removable component from the housing, allowing it to be taken out when not needed. This extraction capability enables the user to maintain the convenience of an integrated device while mitigating the risk of unauthorized use by only carrying the necessary component
