Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air-conditioning systems with voice control functions suffer from low recognition rates of voice control instructions due to the distance and position of voice modules from users, leading to ineffective responses from indoor units.
Innovation Solution
An air-conditioning instruction detection method that acquires the position information of a user relative to an indoor unit and a line control device, determines detection parameters for a voice module based on this information, and controls the voice module to detect voice control instructions accurately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If voice modules are installed in indoor units at high positions, then the air-conditioning system structure is simplified, but the recognition rate of voice control instructions decreases due to increased distance from users
Solution Approach 1:
The patent divides the voice control function into two parts: the infrared sensor for position detection remains in the indoor unit, while the voice module is relocated to the line control device. This segmentation allows each component to be optimally positioned for its specific function, resolving the contradiction between structural simplicity and recognition accuracy.
Solution Approach 2:
The patent introduces a line control device as an intermediary between the indoor unit and the user. This intermediary hosts the voice module closer to the user's position, improving voice recognition while the indoor unit maintains its simplified structure. The line control device mediates the control signals between the voice module and indoor unit.
2Ease of manufacture
If voice modules are positioned far from users in indoor units, then installation is simplified, but the effectiveness of responding to user instructions decreases
Solution Approach 1:
The patent segments the control system functions by placing the voice recognition function in the line control device while keeping the indoor unit structure simple. This allows the voice module to be positioned optimally for user interaction without complicating the indoor unit installation.
Solution Approach 2:
The patent changes the spatial dimension of voice module placement from the vertical high position (indoor unit) to a lower, more accessible position (line control device). This dimensional change improves accessibility and response effectiveness while maintaining installation simplicity through standardized line control device placement.
3Device complexity
If the detection system does not account for user position changes, then the system structure remains simple, but the voice control recognition rate becomes low
Solution Approach 1:
The patent implements a feedback mechanism where the infrared sensor continuously detects user position, and this position information is used to dynamically adjust the voice module's detection parameters. This closed-loop feedback system maintains high recognition rates despite user movement without requiring complex system restructuring.
Solution Approach 2:
The patent makes the detection parameters dynamic by adjusting them based on real-time user position information from the infrared sensor. This dynamic adaptation allows the system to maintain optimal recognition performance as users move, without requiring a fundamentally more complex detection system structure.
