VSEngineering Contradiction Analysis

1Measurement precision

If conventional sensor systems are used for building management, then the system structure is simple, but the measurement precision and reliability of state monitoring are inaccurate and unreliable

Engineering Contradiction:
Improvestate monitoring accuracyVSAvoidsystem structure
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system divides the building into multiple room units, each equipped with independent sensor modules that detect local states (temperature, humidity, occupancy, micro-movements). This segmentation enables precise localized measurements while maintaining overall system manageability through modular architecture.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple sensor modules are merged into a networked system with a central processing unit that integrates data from all sensors. This combination enables cross-room-unit evaluation and comprehensive building management, achieving high measurement precision through data fusion and correlated analysis.

Inventive Principle:
Principle #5Merging (Combining)

2Productivity

If isolated sensor detection is used, then the device complexity is low, but the building management effectiveness is insufficient due to lack of interconnectivity

Engineering Contradiction:
Improvebuilding management effectivenessVSAvoidnetwork interconnectivity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The sensor system is designed with multi-functionality to serve various building management applications including occupancy detection, environmental monitoring, energy optimization, and security. The same sensor network supports multiple management functions, achieving high productivity without proportionally increasing complexity.

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

Solution Approach 2:

The central processing unit continuously receives sensor data, analyzes building states, and generates control signals that feed back to building systems (lighting, HVAC, security). This closed-loop feedback mechanism enables dynamic optimization of building management, improving effectiveness through real-time adjustments.

Inventive Principle:
Principle #23Feedback

3Loss of energy
