Air Conditioner Voice Control with Adaptive Data Format Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioning systems lack efficient and cost-effective methods for voice-activated operation, particularly in scenarios where devices need to be controlled remotely or in environments with varying traffic conditions, leading to potential communication failures and user inconvenience.
Innovation Solution
An air conditioner system with a voice acceptance unit that converts voice instructions into text data for transmission, allowing for flexible and cost-effective voice-activated control, and a communication system that switches between voice and text data formats based on traffic conditions to reduce communication failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If voice data is transmitted in voice format, then communication quality is improved, but communication failure rate increases under high traffic conditions
Solution Approach 1:
The communication system dynamically switches between voice data format and text data format based on traffic conditions. When traffic is light, voice format is used for high quality; when traffic is heavy, text format is used for high efficiency. This dynamic adaptation resolves the contradiction between communication reliability and efficiency.
Solution Approach 2:
The system changes the data format parameter (voice vs. text) according to traffic conditions. Voice data provides better quality but consumes more bandwidth, while text data provides better efficiency but less quality. By changing this parameter based on network status, the system optimizes both reliability and productivity.
2Reliability
If voice acceptance function is integrated into the air conditioner main body, then operation reliability is improved, but device complexity and cost increase
Solution Approach 1:
The voice acceptance function is separated from the air conditioner main body and placed in an external operation unit. This segmentation allows the air conditioner to maintain simple structure while still achieving reliable voice-activated operation through the externally attached voice acceptance unit.
Solution Approach 2:
An external operation unit serves as an intermediary between the user's voice and the air conditioner. This intermediary contains the voice acceptance section and communicates with the air conditioner via cable, enabling voice control without integrating complex voice processing components into the air conditioner itself.
3Adaptability or versatility
If operation unit is externally attached, then adaptability and ease of installation are improved, but signal transmission reliability may decrease
Solution Approach 1:
A cable unit serves as a reliable intermediary connection between the operation unit and the air conditioner main body. This wired connection ensures stable signal transmission while allowing the operation unit to be externally attached for installation flexibility.

AI summary
Provided is an air conditioner including an indoor unit provided with a microphone element for receiving voice instructions, such that a voice instruction spoken by an operator is acquired with high quality and control based on the voice instruction spoken by the operator is likely to be ensured. The air conditioner includes an indoor unit, a transmission unit, and a reception unit. The indoor unit has a main body and a microphone element. The main body has formed therein a blow-out port through which air-conditioned air is blown out toward a space to be air-conditioned. The microphone element accepts a voice instruction captured from a voice capturing portion arranged at a position that deviates from a ventilation space through which the air blown out from the blow-out port flows, in such a manner as to face the space to be air-conditioned. The transmission unit transmits the voice instruction accepted by the microphone element to an outside as a signal. The acceptance unit receives a command corresponding to the signal transmitted from the transmission unit from the outside.
