Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the premises management system relies on location indicators from mobile devices, then the system can provide automated control and location-based functionality, but the system becomes vulnerable to errors when location generation components malfunction

Engineering Contradiction:
Improvelocation-based control functionalityVSAvoidaccuracy of location determination
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system implements anomaly detection that monitors location indicators and provides feedback when deviations from expected patterns are detected. The anomaly detection component analyzes location data and compares it against established criteria, then triggers notifications or remedial actions when anomalies are identified, creating a closed-loop feedback mechanism that improves reliability

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent introduces an intermediary anomaly detection layer between the mobile device location generation components and the premises management system. This intermediary component acts as a mediator that validates location indicators before they are used for automated control decisions, filtering out erroneous data while allowing valid location-based functionality to operate

Inventive Principle:
Principle #24Intermediary (Mediator)

2Extent of automation

If the system automatically changes security modes based on location indicators, then operational automation is improved, but erroneous mode changes occur when location data is inaccurate

Engineering Contradiction:
Improveautomated security mode controlVSAvoidaccuracy of security mode settings
Core Design Contradiction:
Extent of automationVSReliability

Solution Approach 1:

The system performs preliminary anomaly detection and validation of location indicators before executing automated security mode changes. By detecting anomalies in advance and validating location data against established criteria before action is taken, the system prevents erroneous security mode transitions while maintaining automated operational control

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The anomaly detection mechanism provides feedback that validates or rejects location indicators before they trigger automated security mode changes, ensuring that only verified accurate location data results in mode transitions

Inventive Principle:
Principle #23Feedback
