Driverless Vehicle Digital Key System for Simultaneous Door Unlocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driverless vehicles face security risks due to the potential theft of digital keys and require complex maintenance to update authorized keys, and they lack efficient mechanisms for simultaneously unlocking multiple compartments.
Innovation Solution
A driverless vehicle equipped with an electronic lock and control module that generates a unique digital key upon closure detection, allowing only authorized users to access compartments, and includes a method for simultaneously unlocking multiple compartments by generating a single digital key when all closure signals are received, enhancing security and reducing maintenance needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a digital key transmitted via mobile telephone is used for unlocking, then ease of operation is improved, but security deteriorates due to potential theft of used digital keys
Solution Approach 1:
The digital key is made dynamic by regenerating it each time the opening element is closed. This dynamic regeneration ensures that previously captured or stolen keys become invalid, maintaining security while preserving ease of operation through automatic key creation without manual intervention.
Solution Approach 2:
A new digital key is generated in advance upon closure of the opening element, before any potential unauthorized access attempt. This preliminary generation of a fresh key prevents replay attacks and ensures that only the most recent key is valid, resolving the security vulnerability of static keys.
2Ease of operation
If a list of predetermined digital keys is stored in memory, then ease of operation is improved, but device complexity increases due to maintenance requirements for updating the key list
Solution Approach 1:
The need for storing and maintaining a list of predetermined keys in memory is eliminated by extracting this requirement and replacing it with on-demand key generation. The system no longer needs to retain historical keys, significantly reducing memory requirements and maintenance complexity while maintaining ease of operation.
Solution Approach 2:
The system performs self-service by automatically generating new digital keys upon closure detection without requiring external intervention for key updates. This eliminates the maintenance burden of manually updating key lists in memory, reducing device complexity while preserving ease of operation through automatic key management.
3Reliability
If multiple opening elements are locked individually, then security is improved, but ease of operation deteriorates due to manual input requirements for each door
Solution Approach 1:
Multiple opening elements are merged into a single unified locking system controlled by one digital key. When a single digital key is authenticated, it simultaneously unlocks all associated opening elements, eliminating the need for separate manual input for each door while maintaining security through centralized digital authentication.
Solution Approach 2:
The digital key system achieves multi-functionality by serving as a universal key for multiple opening elements. A single authenticated digital key can unlock any or all associated doors, providing versatile access control that improves ease of operation while maintaining security through the same authentication mechanism.
