Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If virtual sound is transmitted through OTA from blockchain platform server, then sound customization and updates are enabled, but security risks from malicious attacks and abnormal transactions increase
Solution Approach 1:
The system performs preliminary security checks including abnormal transaction request detection, iterative attack signal detection, and OTA state tests before allowing virtual sound transmission. The blockchain platform server checks for malicious patterns in advance, and the vehicle communication control device performs additional verification, preventing security issues before they can affect the system.
Solution Approach 2:
The patent introduces an intermediary verification layer between the blockchain platform server and the vehicle sound system. This includes the OTA server that manages transmission, the vehicle communication control device that performs OTA state tests, and the sound processing device that conducts final similarity checks, creating multiple intermediate security checkpoints.
2Reliability
If virtual sound similarity check is performed against vehicle regulation sounds, then safety is improved, but system complexity and processing time increase
Solution Approach 1:
The system extracts only the critical safety function of comparing virtual sounds against regulated vehicle sounds (horn, warning, emergency sounds). This selective extraction focuses computational resources on the most important safety checks while avoiding unnecessary complexity in analyzing all possible sound parameters.
Solution Approach 2:
The similarity check is applied selectively to specific types of sounds that pose safety risks (vehicle regulation sounds and warning sounds) rather than all virtual sounds uniformly. This local application of quality control reduces overall system complexity while maintaining safety where it matters most.
3Reliability
If multiple OTA state tests are performed on virtual sound, then transmission reliability is improved, but transmission time and processing overhead increase
Solution Approach 1:
Multiple security checks and OTA state tests are performed in advance before the actual sound transmission is completed. The blockchain platform server conducts abnormal transaction detection, the OTA server performs transmission checks, and the vehicle communication control device executes OTA state tests, ensuring reliability is established before delivery.
Solution Approach 2:
The verification process operates continuously in the background during normal system operations. The blockchain network continuously monitors transactions, and the vehicle system continuously checks for OTA state compliance, allowing multiple tests to be performed without creating discrete time delays in the user experience.

AI summary
In a sound system that uses over-the-air (OTA), a blockchain platform server is configured to support performance of a virtual sound transaction in a virtual environment. An OTA server is configured to manage a virtual sound transmitted from the blockchain platform server. A vehicle communication control device is configured to perform wireless communication with the OTA server. The vehicle communication control device is configured to download the virtual sound from the OTA server, determine whether the virtual sound is similar to a predetermined specific sound, perform an OTA state test of the virtual sound when the virtual sound is not similar to the predetermined specific sound, and control a sound processing device to play the virtual sound when the virtual sound passes the OTA state test.
