Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional noise testing methods are used in real-world environments, then noise level measurement is achieved, but the complexity of the testing environment and difficulty of accurate simulation increase

Engineering Contradiction:
Improvenoise level measurement accuracyVSAvoidtesting environment complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent creates a virtual copy of the physical testing environment using 3D modeling and acoustic simulation. Instead of conducting complex physical measurements in real-world conditions, the system generates a digital replica that can be repeatedly tested without the complexities of the original environment, maintaining measurement accuracy while eliminating environmental variables.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent introduces acoustic simulation software as an intermediary between the physical product and the measurement process. This intermediary layer processes acoustic data through virtual environment simulations, allowing accurate noise level prediction without direct physical testing in complex real-world settings.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If on-site modifications are made to meet noise standards, then noise compliance is achieved, but the time and cost of product development increase

Engineering Contradiction:
Improvenoise complianceVSAvoidproduct development time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent performs noise compliance evaluation in advance through virtual environment simulations before physical prototyping or on-site modifications. By predicting noise levels in the virtual model, designers can identify and resolve compliance issues during the design phase, eliminating the need for time-consuming on-site modifications later.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces physical trial-and-error modification processes with computational acoustic simulations. Instead of physically modifying products on-site to meet noise standards, the system uses software-based acoustic modeling to predict and optimize noise performance, significantly reducing development time and iterations.

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

3Adaptability or versatility

If multiple testing scenarios are evaluated in physical environments, then comprehensive noise assessment is achieved, but the resource requirements and testing complexity increase

Engineering Contradiction:
Improvetesting scenario flexibilityVSAvoidtesting system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent creates a universal virtual testing platform that can simulate multiple different environments and scenarios within a single system. The 3D virtual environment can be configured to represent various real-world conditions (different locations, structures, materials) without requiring physical reconfiguration, allowing comprehensive noise assessment across multiple scenarios using the same computational infrastructure.

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

AI summary

A method of product visualization and acoustic noise source localization includes receiving acoustic data that is associated with a first product, mapping a sound field around the first product based on the acoustic data, and generating a 3D surface of the sound data for the first product based on the mapping by at least one of interpolating or extrapolating the sound field. The method further includes generating a simulation of the first product by combining the 3D surface with a visual representation of the first product, and providing, via an emitter, an audio output based on the position of an avatar within the simulation with respect to a position of the first product.
