Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a predetermined sampling schedule is used for remote water quality monitoring, then the system is simple to operate and install, but the system cannot dynamically adjust to changing environmental conditions and requires costly on-site access for modifications

Engineering Contradiction:
Improvedynamic adjustment of sampling scheduleVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic call intervals that automatically adjust the sampling schedule based on environmental conditions. The system transitions from static predetermined schedules to dynamic schedules where the call interval modifying module changes sampling frequency in response to threshold-based environmental parameters, enabling adaptability without requiring complex manual intervention

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system incorporates feedback mechanisms where environmental data is continuously monitored and compared against threshold values. When thresholds are exceeded or met, the call interval modifying module automatically adjusts the sampling schedule, creating a closed-loop feedback system that adapts to changing conditions without requiring on-site personnel

Inventive Principle:
Principle #23Feedback

2Ease of operation

If authorized personnel are deployed to remote locations for on-site modifications, then sampling parameters can be adjusted, but access costs increase and response time is delayed

Engineering Contradiction:
Improveparameter modification capabilityVSAvoidresponse time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system enables self-service operation where the monitoring apparatus automatically modifies its own sampling parameters based on environmental conditions. The call interval modifying module allows the system to adjust its operation autonomously without requiring authorized personnel to physically access remote locations, eliminating travel time and enabling immediate parameter modifications

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent introduces a communication server as an intermediary between the remote monitoring apparatus and authorized personnel. This intermediary enables remote parameter modifications to be transmitted electronically to the field device, allowing sampling parameters to be adjusted without physical presence at the remote site while maintaining authorization controls

Inventive Principle:
Principle #24Intermediary (Mediator)

3Measurement precision

If frequent sampling is performed to capture environmental changes, then data quality improves, but energy consumption and operational costs increase

Engineering Contradiction:
Improvedata qualityVSAvoidenergy consumption
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The system dynamically changes the sampling interval parameter based on environmental conditions. During periods of environmental stability, the call interval increases (reducing sampling frequency and energy consumption). When environmental thresholds are exceeded or met, the call interval decreases (increasing sampling frequency to capture changes), thereby maintaining data quality while optimizing energy usage

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The sampling frequency transitions from static to dynamic, allowing the system to concentrate sampling efforts during periods of environmental change while reducing frequency during stable periods. This dynamic approach ensures measurement precision is maintained when needed while minimizing energy consumption during normal operation

Inventive Principle:
Principle #15Dynamics
