Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple signal processing devices are used for multiple displays, then display functionality and versatility are improved, but resource management efficiency deteriorates due to lack of data sharing
Solution Approach 1:
The patent merges multiple signal processing devices into a unified system through a data sharing platform. The first and second signal processing devices share data through defined interfaces, allowing resources to be pooled and managed collectively rather than in isolation, thus improving resource management efficiency while maintaining multiple display functionalities
Solution Approach 2:
The data sharing platform provides universal access to signal processing resources across multiple displays. The system enables any signal processing device to access and utilize data from other devices through standardized interfaces, making the resource management system versatile and applicable to various display configurations
2Loss of information
If data is transmitted between multiple signal processing devices, then comprehensive data availability is improved, but transmission efficiency deteriorates without optimized methods
Solution Approach 1:
The patent implements local quality optimization by categorizing data into different types (first type and second type) and applying different transmission methods accordingly. Important data receives prioritized handling while less critical data uses standard transmission, improving overall transmission efficiency while ensuring comprehensive data availability
Solution Approach 2:
The system dynamically adjusts transmission methods based on data type categorization. The data sharing platform selectively applies different transmission protocols and priority levels depending on the specific data being transmitted, enabling adaptive optimization of transmission efficiency across various data scenarios
3Adaptability or versatility
If virtual machines are executed on hypervisors for data transmission, then system adaptability is improved, but processing complexity increases
Solution Approach 1:
The patent introduces a data sharing platform as an intermediary layer between virtual machines and the underlying hardware. This mediator manages the complexity of data transmission between signal processing devices, allowing virtual machines to operate with simplified interfaces while the intermediary handles the complex coordination and protocol management
