Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If noise levels are mapped using traditional sensor-based methods, then measurement precision is improved, but device complexity and data collection costs increase

Engineering Contradiction:
Improvenoise level measurement precisionVSAvoidsensor network complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces physical acoustic sensors with a machine learning model that processes visual images to predict noise levels. This substitutes the mechanical/sensor-based measurement system with an information-processing system that uses image analysis and trained algorithms to estimate decibel levels without requiring additional hardware sensors in each location.

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

Solution Approach 2:

The patent creates a virtual copy of noise level data by training a machine learning model on paired image-noise datasets. Once trained, the model can generate noise level predictions for new images, effectively copying the noise measurement capability from locations with sensors to locations without sensors through algorithmic inference rather than physical measurement replication.

Inventive Principle:
Principle #26Copying

2Reliability

If comprehensive noise data is collected across multiple areas, then reliability of noise level data is improved, but loss of time and data collection resources increase

Engineering Contradiction:
Improvenoise level data reliabilityVSAvoiddata collection time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent performs preliminary action by collecting and pairing images with their corresponding noise level measurements during periods when sensor data is available. This training phase stores the learned relationships between visual features and noise levels, enabling rapid prediction without real-time sensor deployment. The model is prepared in advance to handle future prediction requests immediately.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces time-consuming physical sensor deployment and continuous monitoring with a pre-trained machine learning model that can instantly predict noise levels from images. This substitution eliminates the need for ongoing sensor data collection while maintaining reliable noise level information across multiple areas.

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

3Ease of operation

If existing mapping technologies are used without noise layer integration, then ease of operation is maintained, but object-affected harmful factors increase due to noise impact on navigation systems

Engineering Contradiction:
Improvenavigation system operation simplicityVSAvoidnoise interference with sound-based navigation
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent merges the noise level prediction functionality with the existing mapping system by integrating the machine learning model into the map generation pipeline. Noise level data is combined with geographic and visual data to create a unified map layer that includes noise information, allowing navigation systems to access noise awareness without requiring separate operational procedures.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces a noise map layer as an intermediary between the physical noise environment and the navigation system. This intermediate representation translates complex acoustic conditions into usable map data that navigation algorithms can process, enabling noise-aware routing while maintaining the simplicity of existing navigation interfaces and operations.

Inventive Principle:
Principle #24Intermediary (Mediator)
