Solution Overview

Problem

Existing air conditioning control systems require complex user input for specifying the area to be air-conditioned and the position of each air conditioner, making it difficult to maintain comfort and save energy, especially in small rooms with a single air conditioner.

Innovation Solution

An air conditioning control device that uses a storage unit to store a floorplan, an area specifying unit to identify areas based on a drawing's hue, and a number specifying unit to determine the number of air conditioners within those areas, allowing for automatic specification and control of air conditioner operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual input setting is used for area and air conditioner position, then control precision is improved, but device complexity and ease of operation deteriorate

Engineering Contradiction:
Improveposition specification accuracyVSAvoidsetting complexity
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The system automatically detects air conditioner positions and areas by processing uploaded floor plan images. The image processing unit extracts positional information and area boundaries without requiring manual input, allowing the system to serve itself in the information gathering process.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Manual mechanical input methods (typing, clicking to define positions) are replaced with automated image processing techniques. The system uses optical recognition and algorithmic analysis of floor plan images to automatically determine positions and areas, substituting manual operations with automated computational processes.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If automated position detection is used, then ease of operation is improved, but measurement precision deteriorates

Engineering Contradiction:
Improvesetting simplicityVSAvoidposition specification accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The system provides feedback by displaying the detected air conditioner positions and area boundaries on the processed floor plan image. Users can review the automatic detection results and correct any errors, ensuring both ease of operation and measurement precision are maintained.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary automated detection to provide initial position and area information. This preliminary action simplifies the user's task by providing a starting point that requires minimal adjustment, combining automation with precision requirements.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If air conditioners operate simultaneously, then comfort is improved, but energy consumption increases

Engineering Contradiction:
Improvecomfort maintenanceVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The control unit operates air conditioners in periodic cycles rather than continuously. By controlling operating time and creating operational sequences, the system maintains comfort through periodic cooling while reducing overall energy consumption compared to simultaneous continuous operation.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system segments the operation of multiple air conditioners by controlling them individually based on their positions and areas. Instead of operating all air conditioners simultaneously, the control unit manages them in divided time periods or sequences, maintaining comfort while reducing total power consumption.

Inventive Principle:
Principle #1Segmentation
