Sliding Door Air Conditioner for 2D Airflow and Safe Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioners lack efficient control over air currents and pose safety and noise concerns due to one-dimensional wind direction adjustment and operational mechanisms.
Innovation Solution
An air conditioner with a sliding door mechanism and sensors for user detection, allowing for two-dimensional air current control, noise reduction, and enhanced safety through automatic operation and voice recognition functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional one-dimensional wind direction adjustment mechanisms (perpendicular vane, horizontal vane) are used, then the structure is simple, but air current cannot be freely controlled and air current control efficiency is poor
Solution Approach 1:
The patent transitions from one-dimensional vane movement to two-dimensional air current control by introducing a linear motor that moves the discharge opening itself in vertical and horizontal directions, enabling freedom control of air current trajectory without relying on complex multi-axis vane systems
Solution Approach 2:
The patent replaces traditional mechanical vane-based wind direction adjustment with an electro-magnetic linear motor system that directly actuates the discharge opening, eliminating mechanical linkages and achieving more precise and flexible air current control
2Adaptability or versatility
If opening and closing structures (door) are provided in air conditioner, then functionality is improved, but noise and safety concerns (body part squeezing) occur during opening and closing operations
Solution Approach 1:
The patent implements automatic door opening/closing operation through sensor-based detection of user presence and system state, eliminating the need for manual intervention and reducing noise from user-induced operational errors or improper handling
Solution Approach 2:
The patent uses sensors to detect user presence and system conditions before executing door opening/closing operations, ensuring that doors only move when safe and appropriate, thereby preventing body part squeezing and reducing unnecessary noise
