Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Echo Dot devices require close proximity and clear line of sight for effective voice recognition, especially in noisy environments, leading to inconvenient user experiences.
Innovation Solution
A portable intelligent voice interactive device with an earphone detachably connected to a body housing, featuring a microphone array and wireless communication, allowing for flexible voice recognition and interaction without distance constraints, even in noisy conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If Echo Dot uses a built-in microphone array, then voice recognition can be performed, but the device requires close proximity and clear line of sight for effective recognition, especially in noisy environments
Solution Approach 1:
The patent introduces an earphone as an intermediary device between the user and the Echo Dot. The earphone contains a microphone that captures voice commands close to the user's mouth, serving as a mediator that overcomes the limitation of the Echo Dot's built-in microphone array requiring close proximity and clear line of sight.
Solution Approach 2:
The patent transitions from a single-point voice recognition approach (Echo Dot's fixed microphone array) to a distributed approach where the earphone's microphone captures voice in a different spatial dimension - directly near the user's mouth rather than from a distance through air transmission, thereby improving recognition accuracy in noisy environments.
2Ease of operation
If Echo Dot is designed as a portable device, then mobility is improved, but additional features like speakers, jacks, and cables are needed for full functionality
Solution Approach 1:
The earphone is designed to perform multiple functions: it serves as a voice command input device with its own microphone, a wireless communication device connecting to the Echo Dot, and a power source through its built-in battery. This multi-functionality reduces the need for additional components in the portable Echo Dot system.
Solution Approach 2:
The patent merges the functions of the earphone and Echo Dot into an integrated system. The earphone's microphone, wireless communication module, and power source are combined with the Echo Dot's voice recognition and processing capabilities, creating a unified portable system that eliminates the need for separate speakers, jacks, and cables.
3Adaptability or versatility
If Echo Dot relies on wireless communication with earphones, then distance constraints are removed, but the system requires both wireless communication modules in earphone and body
Solution Approach 1:
The patent replaces the mechanical connection (physical cable between earphone and Echo Dot) with a wireless communication system. Both the earphone and Echo Dot are equipped with wireless communication modules that use electromagnetic waves to transmit data and control signals, eliminating the need for physical cables and providing distance flexibility.

AI summary
Disclosed is a portable intelligent voice interactive control device including a body and an earphone detachably connected with the body. The body includes a body casing and a rotating cover. An earphone slot is embedded on a surface of the body casing and configured to accommodate the earphone. The earphone is configured to be accommodated in the earphone slot and electrically connected with the body for charging. Horizontal rotation of the rotating cover allows the earphone to be taken out from a taking hole, and after the earphone is taken out, the body communicates with the body through wireless communication.
