Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If static customization calculation is performed using script language with static deployment of codes to all edge nodes, then code consistency and reliability are improved, but research and development efficiency deteriorates due to rigorous testing requirements and code reload needs
Solution Approach 1:
The patent applies dynamics by transitioning from static code deployment to dynamic code loading and execution. The system loads customization calculation scripts dynamically during runtime based on actual requests, allowing code to be updated without reloading or redeploying to all edge nodes. This enables flexible modification of calculation logic while maintaining system reliability through controlled execution environments.
Solution Approach 2:
The patent implements preliminary action by pre-compiling and validating customization scripts before they are executed at edge nodes. The system performs syntax checking, semantic validation, and security verification in advance, so that when scripts are deployed dynamically, they are already proven to be reliable and safe, eliminating the need for rigorous post-deployment testing.
2Stability of the object's composition
If codes are statically deployed to all edge nodes, then system stability is improved, but adaptability deteriorates due to inability to dynamically update code at individual nodes
Solution Approach 1:
The system enables dynamic code adaptation at edge nodes while maintaining overall system stability. Each node can independently load and execute customized scripts based on local requirements, allowing different nodes to run different versions or types of customization logic without affecting other nodes. This dynamic approach provides both adaptability and stability simultaneously.
Solution Approach 2:
The patent segments the code deployment system into independent, modular units that can be loaded and executed separately at each edge node. This segmentation allows individual nodes to adopt different code configurations without requiring system-wide updates, enhancing adaptability while maintaining stability through isolated execution environments.
3Adaptability or versatility
If dynamic code is executed at CDN edge nodes, then flexibility and customizability are improved, but resource occupancy increases
Solution Approach 1:
The patent uses copying by compiling customization scripts into executable bytecode or intermediate representation that can be efficiently cached and reused. Instead of interpreting scripts repeatedly, the system compiles them once into optimized copies that consume fewer computational resources during execution, reducing the resource overhead of dynamic code while maintaining flexibility.
Solution Approach 2:
The system optimizes resource usage by changing the parameter representation of code from high-level script language to optimized executable form. This parameter transformation reduces memory consumption and processing requirements, allowing dynamic code execution with minimal resource impact.
