Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems lack efficient and secure methods for managing the booting and operation of critical and noncritical components based on dependencies, leading to inefficiencies and potential delays in functionality.
Innovation Solution
A method and system that prioritizes the booting and operation of critical components first, followed by noncritical components based on dependencies, utilizing a decentralized database like blockchain for secure and efficient management of vehicle operations and data sharing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If all vehicle components are powered and operated simultaneously, then complete functionality is achieved, but energy consumption increases and boot time is extended
Solution Approach 1:
The vehicle system is segmented into critical and noncritical components. Critical components (powertrain, braking, steering) are powered and operated separately from noncritical components (infotainment, climate control). This segmentation enables selective activation based on operational necessity, reducing overall energy consumption while maintaining essential vehicle functionality.
Solution Approach 2:
Critical components are powered and initialized before noncritical components during system boot-up. This preliminary action ensures that essential vehicle functions are ready before optional features are activated, enabling faster operational readiness for critical systems while deferring energy-intensive noncritical operations.
2Loss of energy
If critical components are prioritized for booting, then energy efficiency improves, but system complexity increases due to dependency management
Solution Approach 1:
The system implements dynamic component activation based on real-time operational requirements. The controller continuously assesses which components are critical for current vehicle operations and activates only those components, rather than using a static all-or-nothing approach. This dynamic management reduces energy waste while the complexity is handled through automated controller logic.
Solution Approach 2:
A centralized controller acts as an intermediary between power sources and vehicle components. This controller manages the complexity of dependency relationships by automatically determining which components need power based on operational context, shielding the rest of the system from the complexity of manual dependency management.
3Reliability
If a decentralized database like blockchain is used, then data security and tamper-proofing are enhanced, but processing time and computational overhead increase
Solution Approach 1:
The system implements selective blockchain integration rather than using it for all data operations. Blockchain is applied only to critical data requiring maximum security and immutability (ownership records, service history, authorization tokens), while less critical data uses traditional storage methods. This partial application maintains security where needed without incurring blockchain processing overhead for all operations.
Solution Approach 2:
Different data types are stored with different security mechanisms based on their specific requirements. Sensitive data requiring tamper-proof storage is placed on the blockchain, while routine operational data uses conventional databases. This local quality approach applies the computationally intensive blockchain technology only where its security benefits are most valuable, optimizing the balance between security and processing time.
