Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual sampling and analysis methods are used, then human crews can collect and analyze samples, but this leads to increased human health and safety risks, higher costs, and longer time consumption

Engineering Contradiction:
ImprovesafetyVSAvoidsampling efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The robotic platform performs sampling and analysis autonomously without requiring human crews to physically traverse hazardous terrain. The system serves itself by integrating both sampling mechanisms and analytical instruments, eliminating the need for human intervention while maintaining continuous operational capability.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical sampling operations with an automated robotic system equipped with sensors and analytical instruments. This substitution eliminates human exposure to hazardous environments while enabling continuous, high-density sampling at accelerated rates.

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

2Measurement precision

If high sampling density is used to reduce uncertainty, then better delineation of COPC distribution is achieved, but this increases the time and cost required for multiple rounds of follow-up sampling

Engineering Contradiction:
Improvedelineation accuracyVSAvoidsampling time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent merges sample collection and analytical measurement into a single integrated robotic operation. By combining the sampling mechanism with on-board analytical instruments, the system performs both functions simultaneously, eliminating the sequential time loss associated with transporting samples to external laboratories and enabling immediate feedback for subsequent sampling decisions.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The robotic platform performs preliminary analytical measurements at the time of sampling, providing immediate data that guides subsequent sampling decisions. This preliminary action eliminates the waiting period traditionally required for laboratory analysis, allowing the system to adaptively plan and execute follow-up sampling rounds without time loss.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If portable analytical devices are used, then field analysis capability is improved, but these devices are cumbersome, time-consuming, and not intrinsically safe for sites with flammable vapors

Engineering Contradiction:
Improvefield analysis capabilityVSAvoiddevice usability
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The robotic platform integrates multiple analytical instruments and sampling capabilities into a single universal system. Rather than deploying separate portable devices for each function, the system combines sample collection, preparation, and multiple types of analytical measurements in one integrated platform, eliminating the need for multiple specialized devices while maintaining field adaptability.

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

Solution Approach 2:

The robotic system acts as an intermediary between the hazardous environment and human operators. By placing analytical instruments on the robot rather than having humans directly handle samples and operate portable devices in hazardous conditions, the system enables field analysis capability while eliminating safety concerns related to flammable vapors and improving ease of operation through remote, automated control.

Inventive Principle:
Principle #24Intermediary (Mediator)
