Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If manual room type assignment by interior designers is used, then room type classification can be established, but the process is time-consuming and cannot adapt to dynamic space usage changes

Engineering Contradiction:
Improveautomated room type determinationVSAvoidsystem complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The system enables rooms to automatically determine their own type by collecting and analyzing motion sensor data from occupants. The motion signature generation and matching process occurs autonomously without requiring manual intervention from interior designers or building managers, allowing the system to self-adapt to changing space usage patterns

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system pre-collects motion sensor data during space usage and generates motion signatures before formal room type assignment is needed. By preparing the data and analysis in advance, the system can quickly determine room types when usage patterns change, eliminating the need for time-consuming manual reassessment

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If automated motion signature analysis is implemented, then room type determination becomes dynamic and adaptive, but data processing and computational requirements increase

Engineering Contradiction:
Improveadaptability to usage changesVSAvoidcomputational energy consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The system extracts only the essential motion characteristics from sensor data to create compact motion signatures. By focusing on key motion patterns rather than processing all raw sensor data, the system achieves high adaptability to usage changes while minimizing computational energy consumption through selective data extraction

Inventive Principle:
Principle #2Taking out (Extraction)

3Measurement precision

If motion sensors are deployed throughout the building, then accurate room type determination can be achieved, but installation and maintenance complexity increases

Engineering Contradiction:
Improvemotion detection accuracyVSAvoidsensor network complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system uses universal motion sensor devices that can be deployed in various room types throughout the building. These multi-functional sensors detect motion patterns applicable to different space configurations and usage types, achieving high measurement precision without requiring specialized sensors for each room type, thereby reducing overall system complexity

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