Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If user-specific parameters are calculated using external equations and resources, then calculation accuracy is improved, but user convenience and time efficiency deteriorate

Engineering Contradiction:
Improvecalculation accuracyVSAvoiduser convenience
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent combines the equation library, calculation algorithms, and user interface into a single integrated device. The processor internally stores multiple equations for calculating user-specific parameters and automatically selects and executes the appropriate equation based on user inputs, eliminating the need for users to separately access external resources or perform manual calculations.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The device performs self-service by automatically determining user-specific parameters through internal processing. When a user initiates a calculation, the processor automatically retrieves relevant equations from memory, inputs user-provided data, performs the calculation, and outputs the result without requiring external assistance or manual computation.

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If manual calculation methods are used, then flexibility in calculation approaches is improved, but time consumption and error probability increase

Engineering Contradiction:
Improvecalculation flexibilityVSAvoidtime consumption
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system dynamically adapts its calculation approach based on user inputs and device settings. The processor can select from multiple stored equations and calculation methods, adjusting the computational pathway in real-time based on the specific parameters provided by the user, thereby maintaining flexibility while automating the process.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If multiple calculation equations are stored internally, then calculation versatility is improved, but device complexity increases

Engineering Contradiction:
Improvecalculation versatilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The processor is designed as a universal computing unit capable of executing multiple different calculation equations and algorithms. Rather than requiring separate hardware components for each calculation type, a single multi-functional processor handles all calculation tasks by loading and executing appropriate software routines from memory, thereby achieving versatility without proportionally increasing hardware complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)
