Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If environmental variables are not measured, then the device complexity is reduced, but the measurement precision deteriorates due to incorrect and non-reproducible results

Engineering Contradiction:
Improvemeasurement precisionVSAvoiddevice complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent introduces an environmental information system as an intermediary component that measures environmental variables (temperature, humidity, air composition) in the working chamber. This mediator system provides data about the measurement environment, enabling correction of measurement results without fundamentally changing the core measurement function, thus improving precision while adding only necessary complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The environmental information system continuously monitors environmental parameters and feeds this information back to the control system. This feedback mechanism allows the system to adjust measurements based on actual environmental conditions, ensuring reproducible results across different locations and times while maintaining a manageable device architecture.

Inventive Principle:
Principle #23Feedback

2Reliability

If environmental parameters are measured and recorded, then the reliability of measurement results is improved, but the device complexity increases due to additional sensors and computer systems

Engineering Contradiction:
ImprovereliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The computer system in the patent serves multiple functions: it controls the measurement process, stores measurement data, processes environmental parameter data, and generates corrected measurement results. By making the computer system multi-functional, the patent improves reliability through comprehensive data management without proportionally increasing device complexity.

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

Solution Approach 2:

The patent combines the environmental information system with the existing measurement device, integrating temperature, humidity, and air composition sensors into the working chamber environment. This merging approach allows the system to gather both measurement data and environmental data through a unified platform, improving reliability while minimizing the increase in device complexity.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If environmental information is collected and processed, then the comparability of measurements across different locations is improved, but the loss of time increases due to additional data collection and processing steps

Engineering Contradiction:
ImprovecomparabilityVSAvoidloss of time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The environmental information system continuously monitors and records environmental parameters before measurements are taken. By having environmental data ready in advance and continuously available, the system eliminates the need for time-consuming environmental assessments during the measurement process, thus improving comparability without significant time loss.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces manual environmental assessment and correction methods with an automated computer system that continuously collects, processes, and applies environmental corrections to measurement data. This substitution of automated digital processing for manual mechanical processes significantly reduces the time required while improving the accuracy and comparability of measurements across different locations.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
