Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Physical car keys can be stolen or lost, allowing unauthorized access to vehicles, posing a security risk.
Innovation Solution
A portable or wearable electronic device with a physiological feature detection module and processing circuit is used to authenticate authorized users by detecting unique physiological features, such as fingerprints or heart rate patterns, to control vehicle access and adjust in-car settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a physical car key is used to open/start a vehicle, then the vehicle can be accessed and started, but the key may be stolen or lost, allowing unauthorized access
Solution Approach 1:
The patent replaces the mechanical physical key system with a biological authentication system using physiological feature detection (fingerprint, facial recognition, iris scanning). This substitution eliminates the risk of physical key theft or loss while maintaining reliable vehicle access control, directly resolving the security vulnerability of mechanical keys.
Solution Approach 2:
The patent introduces an electronic intermediary device (mobile phone, wearable device, or vehicle-mounted system) that mediates between the user and the vehicle. This intermediary contains the physiological feature database and authentication logic, acting as a secure bridge that verifies user identity before granting vehicle access, thereby preventing unauthorized access without requiring physical key exchange.
2Reliability
If physiological feature detection is implemented for user authentication, then unauthorized access is prevented, but device complexity increases
Solution Approach 1:
The patent leverages existing multi-functional devices (smartphones, wearable electronics, vehicle infotainment systems) that already possess processing power, display capabilities, and communication functions. By integrating physiological feature detection into these existing devices rather than creating dedicated authentication hardware, the system achieves high security while minimizing additional complexity, as the host device handles multiple functions including authentication.

AI summary
A portable electronic device to be used as a keyless device of a vehicle includes a controlling circuit which includes a physiological feature detection module and a processing circuit. The physiological feature detection module is used for detecting a physiological feature of a person. The processing circuit is coupled to the physiological feature detection module and used for determining whether the person is an authorized user of the vehicle according to the detected physiological feature of the person, and for opening a car door of the vehicle or starting the vehicle when the person is identified by the processing circuit as the authorized user.
