Solution Overview

Problem

In environments with multiple air conditioners installed closely together, overlapping detection areas can lead to simultaneous control actions on individuals, causing discomfort and energy wastage, as existing systems lack accurate position information for intelligent control.

Innovation Solution

The air conditioner control method involves detecting a positioning marker, such as a heat source, using sensors like infrared or radar, determining if other air conditioners also detect the marker, and calculating the position relation to ensure only one air conditioner takes control in overlapping areas.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If multiple air conditioners are installed closely together to cover overlapping areas, then the coverage area is improved, but simultaneous control actions cause discomfort and energy waste

Engineering Contradiction:
Improvedetection area coverageVSAvoidenergy waste from simultaneous operation
Core Design Contradiction:
Area of stationary objectVSLoss of energy

Solution Approach 1:

The system uses detection feedback from positioning markers to determine which air conditioner should control a person. When multiple air conditioners detect the same person, they exchange detection information and use feedback mechanisms to select one controller, preventing simultaneous operation and energy waste while maintaining overlapping coverage areas

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

A controller acts as an intermediary between multiple air conditioners and the person. The controller receives detection information from multiple air conditioners, processes the positioning data, and coordinates control actions to ensure only one air conditioner operates on each person, resolving the conflict between overlapping coverage and energy efficiency

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If multiple air conditioners simultaneously control a person in overlapping areas, then detection capability is improved, but control comfort deteriorates

Engineering Contradiction:
Improvedetection capabilityVSAvoidcontrol discomfort
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system implements feedback loops where air conditioners continuously exchange detection status information. When multiple air conditioners detect a person, the feedback mechanism allows them to identify overlapping detection areas and coordinate to provide control information to only one air conditioner, ensuring reliable detection while preventing uncomfortable simultaneous control actions

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent merges the control functions of multiple air conditioners through a coordinated control mechanism. By combining detection information from multiple units and consolidating control actions through a controller, the system maintains enhanced detection capability while ensuring that control effects are merged into a single action, improving comfort in overlapping areas

Inventive Principle:
Principle #5Merging (Combining)
