Solution Overview

Problem

Existing smart home and building management systems lack the ability to accurately define and manage spatial zones based on environmental data, leading to inefficient operation of systems like HVAC, lighting, and security, as they often rely on blanket settings rather than zone-specific customization.

Innovation Solution

A zoning system that uses network-connected sensors to capture and analyze data, automatically identifying trends and patterns to define spatial zones, which are then used to customize the operation of other systems, such as HVAC, lighting, and security, by configuring them based on zone definitions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If blanket settings are used for system operation, then device complexity is reduced, but measurement precision of spatial zones deteriorates

Engineering Contradiction:
Improvesystem configurationVSAvoidspatial zone definition
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The system divides the premises into multiple spatial zones based on sensor data analysis, allowing each zone to have independent operational settings. This segmentation enables precise spatial zone definition without requiring complex manual configuration of each individual zone, as the zones are automatically created and managed by the system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system automatically defines spatial zones and configures system operations based on sensor data patterns without requiring manual user intervention. The processor autonomously analyzes sensor data, identifies trends, creates zone definitions, and adjusts HVAC, lighting, and security settings, eliminating the need for complex user setup while maintaining high measurement precision.

Inventive Principle:
Principle #25Self-service

2Productivity

If zone-specific customization is implemented, then productivity of system operation is improved, but device complexity increases

Engineering Contradiction:
Improvesystem operation efficiencyVSAvoidsystem configuration
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system automatically performs zone definition and configuration tasks without manual user input. The processor analyzes sensor data, identifies occupancy patterns, and autonomously creates and manages zone-specific settings for HVAC, lighting, and security systems, achieving high operational efficiency while keeping the user interface simple.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system pre-configures zone definitions and operational parameters based on historical sensor data and occupancy patterns before user needs arise. By continuously learning and updating zone configurations in advance, the system is ready to optimize operations immediately when conditions change, improving productivity without requiring complex real-time user configuration.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If manual zone configuration is used, then ease of operation is maintained, but adaptability to changing zone usage deteriorates

Engineering Contradiction:
Improvesystem setupVSAvoidzone usage changes
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The system automatically adapts to changing zone usage by continuously analyzing sensor data and updating zone definitions without requiring manual reconfiguration. When occupancy patterns change, the processor detects these changes and automatically adjusts zone boundaries and operational settings, maintaining ease of operation while achieving high adaptability.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements dynamic zone definitions that automatically adjust based on real-time and historical sensor data. Zone boundaries, occupancy patterns, and operational parameters are continuously updated to reflect changing usage conditions, allowing the system to adapt seamlessly to new situations without manual intervention while keeping the user interface simple and static.

Inventive Principle:
Principle #15Dynamics

4Measurement precision

If sensor data analysis is performed to define zones, then measurement precision of spatial zones is improved, but use of energy increases

Engineering Contradiction:
Improvespatial zone definitionVSAvoiddata processing
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The system performs sensor data analysis at optimized intervals and only processes data necessary for zone definition and validation. Rather than continuously analyzing all sensor data, the processor focuses on key occupancy patterns and environmental changes, achieving high measurement precision while minimizing energy consumption through selective and interval-based data processing.

Inventive Principle:
Principle #16Partial or excessive action
