Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hardware resources are fixed during software compilation stage, then driver can use specified hardware resource, but driver cannot be dynamically configured and modified during software operation
Solution Approach 1:
The patent implements dynamic configuration by introducing a configuration file that can be loaded at runtime, allowing hardware resource parameters to be modified without recompiling the driver. The driver reads configuration from external files (e.g., JSON, XML, YAML) enabling flexible adjustment of hardware resources during system operation.
Solution Approach 2:
The patent changes the state of hardware resource configuration from fixed at compile-time to variable at runtime. By externalizing configuration parameters into separate configuration files, the system allows parameter changes without modifying the driver code or recompiling, thus achieving flexible adaptation to different hardware scenarios.
2Adaptability or versatility
If different hardware resource configurations require different software versions, then each device configuration can have dedicated software, but the number of software versions increases and management and maintenance workload increases
Solution Approach 1:
The patent creates a universal driver that can support multiple device configurations through a single software version. The driver incorporates a configuration file interface that allows it to adapt to different hardware setups, eliminating the need for separate software versions for each device type.
Solution Approach 2:
The patent introduces a configuration file as an intermediary between the driver and hardware resources. This configuration file acts as a mediator that translates hardware-specific parameters into driver-compatible formats, allowing a single driver to work with multiple hardware configurations without requiring multiple software versions.
3Ease of manufacture
If hardware resource configuration is fixed at compilation stage, then software compilation is straightforward, but seamless hardware resource adjustments during operation cannot be achieved
Solution Approach 1:
The patent segments the software system into two independent parts: the driver code (compiled once) and the configuration file (modifiable at runtime). This segmentation allows the driver to remain simple and stable while the configuration file provides flexibility for hardware resource adjustments without affecting compilation complexity.
