Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a microphone accommodating groove is provided in the smart speaker, then the microphone can be accommodated, but the microphone cannot be charged
Solution Approach 1:
The microphone accommodating groove is enhanced to serve dual functions: accommodation and charging. Charging rings are integrated into the groove structure, allowing the same space to provide both mechanical support and electrical charging capability when the microphone is placed within the groove.
Solution Approach 2:
The charging function is merged with the accommodating groove by integrating charging rings directly into the groove structure. This combines what were previously separate functions (accommodation and charging) into a unified component system.
2Adaptability or versatility
If charging rings are added to the microphone, then charging function is enabled, but contact reliability deteriorates during transportation
Solution Approach 1:
The charging probe assembly is pre-positioned and extended toward the charging rings before the microphone is fully inserted. This preliminary positioning ensures that electrical contact is established early in the insertion process and maintained throughout transportation, preventing contact loss.
Solution Approach 2:
The charging probe assembly is designed to be movable rather than fixed, allowing it to dynamically adjust its position to maintain continuous contact with the charging rings during microphone insertion and transportation movements.
3Reliability
If magnetic assemblies are used for attachment, then secure attachment is achieved, but manufacturing complexity increases
Solution Approach 1:
The magnetic assemblies automatically attract and secure the microphone to the speaker without requiring additional mechanical fasteners or complex assembly steps. The magnetic force self-aligns and holds the components together, simplifying the manufacturing and assembly process despite the added magnetic components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures effective charging of the microphone while preventing poor contact during transportation, enhancing user experience by maintaining a secure electrical connection and compact design.
Implementation Method 1
since the microphone internal magnetic assembly and the speaker internal magnetic assembly are magnetically attracted to each other, the magnetic microphone is tightly attached in the microphone accommodating groove
Implementation Method 2
the charging probe assembly is in a conductive connection with each charging ring to locate the magnetic microphone

AI summary
A horizontally-charging smart acoustic system includes a magnetic microphone, an interior of the magnetic microphone is provided with a microphone internal magnetic assembly and a flip speaker assembly. An exterior of the magnetic microphone is provided with multiple charging rings arranged along an axial direction of the magnetic microphone. The flip speaker assembly includes a speaker base provided with a microphone accommodating groove, a speaker internal magnetic assembly mounted under the microphone accommodating groove and arranged in correspondence to the microphone internal magnetic assembly, a charging probe assembly protruding into the microphone accommodating groove and in an electrical connection with each charging ring, and an upper cover assembly in a hinged connection with the speaker base. The horizontally-charging smart acoustic system provided in the present application can effectively solve the problem that the existing smart speaker cannot charge the microphone and causes a bad user experience.
