Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote controller and security card-based vehicle control systems are inconvenient for users, as they require carrying additional devices and may result in unauthorized access if lost.
Innovation Solution
A steering wheel with a cover layer incorporating touch and pressure sensors, which generates authentication information based on user interactions, including fingerprint recognition, to securely control vehicle access and functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a remote controller or security card is used for vehicle access control, then vehicle security is maintained, but user convenience deteriorates due to the need to carry additional devices
Solution Approach 1:
The patent combines the vehicle access control function with the steering wheel, integrating the authentication sensor into the steering wheel cover layer. This merging eliminates the need for separate remote controllers or security cards, as the steering wheel itself becomes the authentication device through fingerprint recognition.
Solution Approach 2:
The steering wheel is given multiple functions: it serves both as the traditional steering control device and as an authentication device for vehicle access. The cover layer with integrated sensor enables the steering wheel to perform both mechanical steering and biometric verification functions.
2Reliability
If a remote controller or security card is used for vehicle access control, then unauthorized access is prevented, but user convenience deteriorates when the device is lost
Solution Approach 1:
The authentication system uses the user's own fingerprint, which is always available on their body, rather than requiring an external device like a card or remote. The biometric data is inherently tied to the user, eliminating the problem of losing the authentication device.
3Ease of operation
If fingerprint recognition is integrated into the steering wheel cover layer, then authentication convenience is improved, but device complexity increases
Solution Approach 1:
The patent uses a flexible cover layer made of thin film material that can be integrated into the steering wheel structure. This thin film contains the sensor and allows fingerprint authentication while maintaining the steering wheel's mechanical properties and aesthetic appearance.
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
Enhances security and convenience by allowing secure vehicle access through biometric authentication and enabling control of vehicle functions directly through the steering wheel, reducing the need for separate remote controllers or cards.
Implementation Method 1
the touch sensor includes a plurality of sensor pixels which senses a capacitance change corresponding to the touch
Implementation Method 2
the cover layer may further include a pressure sensor which generates pressure information based on a pressure change by the touch of the user
Data Source
AI summary
A steering wheel includes a wheel frame, and a cover layer covering the wheel frame. The cover layer includes a touch sensor which generates touch information based on a touch of a user, and the touch sensor includes a plurality of sensor pixels which senses a capacitance change corresponding to the touch.
