Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air-conditioning systems with voice control modules installed at high positions suffer from low recognition rates due to the influence of changing user positions, leading to ineffective responses to voice instructions.
Innovation Solution
An air-conditioning instruction detection method that determines the position of a user relative to a line control device, adjusts detection parameters of the voice module based on this position, and controls the voice module to accurately detect voice instructions, ensuring timely and effective responses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the voice module is installed in the indoor unit at high position, then the device structure is simplified, but the voice instruction recognition accuracy deteriorates due to distance from users
Solution Approach 1:
The system divides the voice detection function into two parts: the indoor unit (high position) handles infrared detection and position tracking, while the line control device (low position near user) handles voice module detection. This segmentation allows each component to operate from its optimal position without compromising overall system performance.
Solution Approach 2:
The line control device acts as an intermediary between the user and the indoor unit. It receives voice instructions from users at ground level, processes them locally with the voice module, and transmits control signals to the indoor unit, thereby bridging the distance gap between user and high-mounted equipment.
2Device complexity
If the voice module detects instructions without considering user position changes, then the detection process is simple, but the recognition rate deteriorates
Solution Approach 1:
The infrared sensor continuously tracks user position and provides feedback to the controller. The controller dynamically adjusts the voice module's detection parameters based on real-time position information, ensuring optimal recognition accuracy regardless of user movement within the room.
Solution Approach 2:
The system transitions from static detection parameters to dynamic adjustment. The voice module's detection sensitivity, direction, and other parameters are continuously adapted based on the user's real-time position, allowing the system to maintain high recognition rates as users move around the room.
3Ease of manufacture
If the indoor unit is installed at high position for easy installation, then installation ease is improved, but the distance from users causes ineffective response to voice instructions
Solution Approach 1:
The line control device serves as an intermediary that bridges the gap between the high-mounted indoor unit and ground-level users. It houses the voice module at an accessible position for effective voice detection while maintaining connection to the indoor unit, thus preserving both installation advantages and operational effectiveness.
