Solution Overview

Problem

Conventional air conditioners face issues with temperature accuracy, as the difference between the user's position and the remote controller's position increases, leading to a larger error between the actual and target temperatures.

Innovation Solution

A controller system that includes a floor-map-information storing unit, user-registration-information storing unit, user information acquiring unit, and air-conditioning control unit, which uses floor map information, user registration information, and user information to control the air conditioner, ensuring the temperature at the user's position approaches the target temperature detected by nearby sensor terminals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the temperature is detected by the sensor attached to the remote controller, then the air conditioning can be performed, but the error between the actual temperature at the user position and the target temperature becomes large when the distance between user and remote is large

Engineering Contradiction:
Improvetemperature measurement accuracyVSAvoidsystem configuration complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The room is divided into multiple zones with sensor terminals strategically positioned in each zone. Instead of using a single remote controller sensor, multiple sensor terminals are distributed throughout the room to detect temperatures at different locations, enabling more accurate representation of the actual temperature environment.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Sensor terminals act as intermediaries between the user and the air conditioner. These terminals are positioned near users and transmit temperature data to the controller, which then controls the air conditioner to maintain the target temperature at the user's position, eliminating the need for users to carry remote controllers with sensors.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If multiple sensor terminals are installed to improve temperature measurement accuracy, then the temperature control precision improves, but the device complexity and installation cost increase

Engineering Contradiction:
Improvetemperature measurement accuracyVSAvoidnumber of sensor terminals
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The sensor terminals are designed to serve multiple functions: they detect temperature, identify user presence, and provide location information. This multi-functionality reduces the need for separate devices and justifies their deployment throughout the room, as each terminal contributes to multiple aspects of the air conditioning control.

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

Solution Approach 2:

The system automatically selects the appropriate sensor terminal based on user position information without requiring manual intervention. The controller acquires user position data, automatically determines which sensor terminal is nearest to the user, and uses that terminal's temperature data for control, making the system self-configuring and reducing operational complexity.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If the air conditioner controls based on remote controller position, then the system is simple to operate, but the temperature control accuracy at user position deteriorates

Engineering Contradiction:
Improveoperation simplicityVSAvoidtemperature control accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The system automatically determines the user's position and selects the appropriate sensor terminal without requiring the user to manually operate the remote controller or indicate their position. The controller autonomously acquires user information, identifies the nearest sensor terminal, and controls the air conditioner accordingly, maintaining simplicity while improving accuracy.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system continuously monitors user position information and dynamically selects the most appropriate sensor terminal based on real-time data. This feedback mechanism ensures that the temperature control is always based on the most relevant temperature measurement, adapting to changes in user position without requiring user intervention.

Inventive Principle:
Principle #23Feedback

AI summary

A controller includes: a processor and a memory. The memory stores floor map information indicating a position of each sensor terminal in a room air-conditioned by an air conditioner. The memory also stores user registration information including first identification information indicating a user who may be in the room and positional information indicating a position occupied by the user when the user is in the room. The processor periodically acquires, from a user terminal, user information including second identification information indicating the user using the user terminal and target temperature information. The processor controls, when the user using the user terminal is in the room, the air conditioner such that temperature detected by one of the sensor terminals at a position near the user in the room approaches target temperature indicated in the target temperature information based on floor map information, user registration information, and user information.
