Solution Overview

Problem

Wall-mounted air conditioners are often installed out of reach, necessitating the use of a remote controller for operation, which can be inconvenient and less efficient compared to voice control.

Innovation Solution

Integration of a speech recognizer within the air conditioner, including a microphone and speaker positioned for optimal sound reception and isolation, along with a wireless communication module and vibration-reducing components, allowing users to control the device via voice commands.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a remote controller is used to operate the air conditioner, then the air conditioner can be controlled from a distance, but the operation becomes less efficient and convenient compared to voice control

Engineering Contradiction:
Improveoperation convenienceVSAvoidcontrol system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical remote controller system with an acoustic voice recognition system. The microphone receives voice commands, the speech recognizer processes them, and the controller executes the commands, substituting the need for physical remote control devices with a hands-free voice-based interface that is more convenient and efficient

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If the microphone and speaker are disposed to direct to the lower part of the housing, then sound reception and output are optimized, but vibration from the speaker may be transmitted to the housing

Engineering Contradiction:
Improvesound reception qualityVSAvoidvibration transmission
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a vibration reducing member as an intermediary component positioned between the speaker and the housing. This intermediary element absorbs or dampens the vibrations generated by the speaker, preventing them from being transmitted to the housing structure while allowing the speaker to maintain its optimal positioning for sound output

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If the case includes a partition wall to isolate the speaker and microphone, then noise interference is reduced, but the device complexity increases

Engineering Contradiction:
Improvenoise isolationVSAvoidcase structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent divides the case into separate compartments using partition walls, creating distinct spaces for the speaker and microphone. This segmentation physically isolates the two components, preventing noise interference between them while maintaining a relatively simple overall case structure through the use of straightforward partitioning elements

Inventive Principle:
Principle #1Segmentation
