Air Conditioner Pressure-Based Wind Control for User Location Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioners struggle to create a comfortable indoor environment when the sensor is not placed at the intended location by the user, leading to ineffective control based on sensor measurements rather than user-defined preferences.
Innovation Solution
An air conditioner system that communicates with a portable terminal equipped with an air pressure measurement unit, allowing it to calculate wind velocity and determine the presence direction, enabling the air conditioner to adjust wind direction and airflow volume to optimize comfort at the user's desired location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the air conditioner is controlled based on values measured by a sensor mounted on the indoor unit, then the control system is simple and reliable, but the air conditioner cannot set a comfortable environment at the user's intended location when the sensor is not placed there
Solution Approach 1:
The patent introduces a portable terminal as an intermediary device that measures air pressure and communicates with the air conditioner. This mediator enables the air conditioner to obtain environmental data from the user's intended location without requiring direct sensor installation at that location, thus improving adaptability while maintaining system simplicity
Solution Approach 2:
The portable terminal serves multiple functions: it acts as a mobile sensor for air pressure measurement, a communication device for data transmission, and a user interface for controlling the air conditioner. This multi-functionality allows the system to adapt to different user locations without adding dedicated sensors at each position
2Measurement precision
If the air conditioner uses a fixed sensor placement for environmental measurement, then the device complexity is low, but the measurement accuracy at the user's intended location deteriorates when the sensor is not placed there
Solution Approach 1:
The system transitions from a static sensor placement to a dynamic measurement approach where the portable terminal can be moved to different locations. The air conditioner dynamically adjusts its operation based on real-time air pressure measurements from the user's current location, improving measurement precision without requiring fixed sensor installation at multiple positions
Solution Approach 2:
The portable terminal acts as a mobile intermediary that brings the measurement capability to the user's intended location rather than requiring the location to have a fixed sensor. This mediator enables accurate environmental measurement at any user position while keeping the overall system simple
3Ease of operation
If the air conditioner adjusts wind direction and airflow volume based on real-time air pressure data from the portable terminal, then the comfort at the user's location is improved, but the device complexity and control complexity increase
Solution Approach 1:
The system implements a feedback loop where the portable terminal continuously measures air pressure at the user's location and communicates this data to the air conditioner. The air conditioner uses this feedback to automatically adjust wind direction and airflow volume, improving user comfort through real-time adaptation without requiring complex manual controls
Solution Approach 2:
The air conditioner performs self-adjustment of its operation based on air pressure data from the portable terminal. The system automatically determines the user's location and adjusts its output accordingly, eliminating the need for complex user intervention while improving comfort at the intended location
