Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If optical or ultrasonic measuring methods are used to measure wall thicknesses, then measurement can be performed, but measurement accuracy is impaired by non-uniform container geometries and varying absorption/transmission coefficients

Engineering Contradiction:
Improvewall thickness measurement accuracyVSAvoidinterference from container geometry and material properties
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

A numerical model acts as an intermediary between the raw measurement data and the final performance parameter determination. The model incorporates container geometry, material properties, and measurement conditions to correct measured values and compensate for interference factors, thereby restoring measurement accuracy without changing the physical measurement process itself.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system changes the parameters used for quality assessment from direct raw measurements to corrected values that account for geometric and material variations. By transforming the measurement data through a numerical model that considers absorption coefficients, transmission properties, and container geometry, the system achieves accurate performance parameter determination despite the interfering factors.

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If performance parameters are determined based on raw measured container parameters, then production optimization can be attempted, but the determination is unreliable due to measurement inaccuracies

Engineering Contradiction:
Improveperformance parameter determination accuracyVSAvoidreliability of performance parameter values
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The numerical model serves as a reliable intermediary that processes raw measurement data into corrected values. By incorporating knowledge of container geometry, material properties, and measurement physics, the model reliably transforms unreliable raw measurements into accurate performance parameter determinations, enabling trustworthy production optimization.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system establishes a feedback loop where measured container parameters are continuously corrected using the numerical model, and the determined performance parameters feed back into production parameter optimization. This closed-loop approach ensures that production decisions are based on reliable, corrected data rather than unreliable raw measurements.

Inventive Principle:
Principle #23Feedback

3Measurement precision

If measurement systems are designed to account for all interference factors, then measurement accuracy improves, but device complexity increases

Engineering Contradiction:
Improvecontainer parameter measurement accuracyVSAvoidcomplexity of measurement and correction system
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

Rather than complicating the physical measurement system to account for all interference factors, the patent introduces a numerical model as a computational intermediary. This software-based approach handles the complexity of correcting for geometry and material variations without requiring additional or more complex physical measurement hardware, thus improving accuracy while minimizing device complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)
