Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sound data is transferred through recording media (CD, USB, etc.), then data can be securely transferred between devices, but the process requires multiple manual steps and significant user time
Solution Approach 1:
The patent introduces a server as an intermediary between the electronic musical instrument and the sound data source. The server stores sound data and provides authorized access to multiple devices, eliminating the need for physical recording media transfer while maintaining security through authorization management. This resolves the contradiction by automating the data transfer process through a centralized platform.
Solution Approach 2:
The patent replaces the mechanical system of physical recording media (CDs, USB drives) with an electronic network-based system. Instead of manually copying data to physical media and transferring it between devices, the system uses network communication to deliver sound data directly to the electronic musical instrument, significantly reducing user time while maintaining security through digital authorization.
2Ease of operation
If direct network connection is established between electronic musical instrument and server, then data access becomes faster and easier, but network configuration and security management become more complex
Solution Approach 1:
The patent makes the server a universal access point for multiple electronic musical instruments and other devices. The server handles network communication, authentication, and data delivery for various devices with different capabilities, simplifying the client devices while centralizing the complexity in the server. This allows fast and easy data access without requiring complex network configuration in each device.
Solution Approach 2:
The server acts as an intermediary that manages all network communication and security aspects. Client devices only need simple connectivity to the server, while the server handles complex authentication, authorization, and data transmission protocols. This resolves the contradiction by isolating network complexity in the server while keeping client devices simple.
3Reliability
If authorization information is stored locally in each device, then access control is maintained, but device storage is consumed and security management becomes difficult
Solution Approach 1:
The server serves as a centralized intermediary for storing and managing authorization information. Instead of duplicating authorization data in each device's storage, the server maintains the master authorization database and verifies credentials during access requests. This preserves security while eliminating local storage requirements for authorization data.
Solution Approach 2:
The patent uses lightweight copies of authorization credentials (such as tokens or session identifiers) that are much smaller than full authorization databases. These minimal copies are stored temporarily in devices for verification purposes, significantly reducing storage consumption while maintaining access control security through the server's ability to validate these credentials.
4Adaptability or versatility
If multiple devices access the same server simultaneously, then resource sharing is improved, but authorization management becomes more complex
Solution Approach 1:
The server is designed as a universal platform that handles authorization and data delivery for multiple diverse devices simultaneously. It implements a unified authorization framework that works across different device types, user accounts, and data requests, simplifying multi-device access while maintaining security through centralized control.
Solution Approach 2:
The patent implements feedback mechanisms where the server continuously monitors device connections, authorization status, and data access patterns. Based on this feedback, the server dynamically manages authorization tokens, updates device permissions, and coordinates data delivery to multiple devices. This feedback loop simplifies multi-device authorization management by making the system responsive to actual usage conditions.
