Helmet-Mounted Camera Authentication for Saddle-Type Vehicle Unlocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional saddle-type vehicle systems require riders to perform additional motions for face authentication, such as turning their face towards a camera, which is bothersome and lacks enhanced security, especially when unlocking the vehicle using a key or imaging elements attached to mobile terminals or vehicle bodies.
Innovation Solution
A saddle-type vehicle system with an occupant authentication device integrated into the helmet, featuring a small camera and authentication unit that performs authentication during normal riding motions, allowing the vehicle to be unlocked by the owner without needing to explicitly face a camera, enhancing security and simplifying the authentication process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If face authentication is performed using a camera on a mobile terminal or vehicle body, then authentication function is provided, but additional motion of turning face toward the camera is required which is bothersome
Solution Approach 1:
The helmet-mounted camera performs face authentication automatically without requiring the rider to perform additional actions. The rider simply needs to wear the helmet, and the system captures the face image and performs authentication autonomously, making the system serve itself rather than requiring active user participation in the authentication process
Solution Approach 2:
The face image is captured and authentication is performed in advance before the rider needs to operate the vehicle. By completing the authentication process while the rider is putting on or adjusting the helmet, the system ensures security is established before any vehicle operations begin, eliminating the need for additional authentication actions later
2Ease of operation
If normal locking with unlocking key is used, then simple unlocking operation is achieved, but security is compromised as lock can be released by anyone with the key or if key is lost
Solution Approach 1:
The mechanical key-based locking system is replaced with a biometric authentication system using face recognition. Instead of relying on a physical key that can be lost or copied, the system uses the rider's unique facial features captured by the helmet camera, substituting mechanical authentication with optical and biometric methods to enhance security while maintaining operational simplicity
3Adaptability or versatility
If multiple persons need to be identified for authentication, then comprehensive access control is provided, but authentication system complexity increases
Solution Approach 1:
The authentication system is segmented into distinct functional modules: a camera module for capturing face images, an authentication unit for processing and comparing images, and a lock control unit for executing unlocking actions. This modular segmentation allows the system to handle multiple authentication scenarios while keeping each component's complexity manageable and enabling independent optimization of each module

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution improves security by allowing prompt and easy unlocking during normal riding motions, enhances moral compliance by ensuring helmet usage, and simplifies authentication by identifying only the vehicle owner, reducing the need for multiple person identification and data management.
Implementation Method 1

AI summary
A saddle-type vehicle includes a helmet (32) and an occupant authentication device (50) configured to perform authentication of an occupant (12) by a small camera (38) (an imaging element) provided in the helmet (32). The occupant authentication device (50) releases lock on the vehicle (10) if the occupant (12) is authenticated.
