Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If complete software configuration scheme is used with programmable hardware like FPGA, then adaptability to different communication standards is improved, but cost, power consumption, and device bulk increase significantly

Engineering Contradiction:

Improveadaptability to different communication standardsVSAvoidpower consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent segments the radio device into fixed hardware modules for basic functions and software-configurable modules for standard-specific functions. This segmentation allows the device to maintain adaptability through software while using energy-efficient fixed hardware for common operations, resolving the contradiction between adaptability and power consumption.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by making only the necessary portions of the device software-configurable rather than the entire device. Specifically, certain modules are implemented as software to provide adaptability where needed, while other modules use fixed hardware implementation for energy efficiency, thus resolving the contradiction between adaptability and power consumption.

Inventive Principle:

Principle #3Local quality

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent extracts commonly used functions from software configuration and implements them as fixed hardware modules. This extraction reduces the volume of configuration information needed while maintaining functional flexibility, as the fixed hardware modules provide basic functionality without requiring software configuration.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent performs preliminary action by pre-configuring certain modules as fixed hardware with built-in functionality. This preliminary configuration eliminates the need to load and process large amounts of configuration data for these functions, reducing memory requirements and loading time while maintaining adaptability through software-configurable modules.
