Portable Karaoke Module With Vehicle Audio Auto-Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing karaoke microphones for vehicles lack dedicated storage compartments and cannot be used independently outside the vehicle, requiring complex installation and potentially protruding components that pose safety risks.
Innovation Solution
A portable karaoke module with a housing containing a microphone, loudspeaker, control unit, and rechargeable energy storage, designed to be inserted into a vehicle's module receptacle, automatically pairing with the vehicle's audio system for seamless operation, and featuring a push-push locking mechanism for secure microphone mounting and energy transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If karaoke microphones are designed as separate external components, then they can be used independently outside the vehicle, but they lack dedicated storage compartments and require complex installation
Solution Approach 1:
The patent combines the microphone, housing, loudspeaker, control unit, and energy storage device into a single integrated karaoke module that can be inserted into a vehicle's module receptacle. This merging eliminates the need for separate storage compartments and simplifies installation while maintaining the ability to use the module independently outside the vehicle.
Solution Approach 2:
The karaoke module is designed with multi-functionality to serve dual purposes: it can be installed in the vehicle's module receptacle for in-vehicle use, or used independently outside the vehicle as a portable karaoke system. The integrated design provides both storage and functionality in a single unit.
2Ease of manufacture
If the housing is designed to be inserted into the vehicle's module receptacle, then installation effort is minimized and space is saved, but the components may protrude and pose safety risks
Solution Approach 1:
The housing is designed with dimensional considerations to ensure it fits properly within the vehicle's module receptacle without protruding harmful components. The shape and size of the housing are optimized to accommodate all components (microphone, loudspeaker, control unit, energy storage device) within the receptacle's boundaries, eliminating safety risks while maintaining easy installation.
3Adaptability or versatility
If the karaoke module includes all components (microphone, loudspeaker, control unit, energy storage) in one housing, then it can be used independently outside the vehicle, but it increases the device complexity
Solution Approach 1:
The karaoke module is segmented into distinct functional components (microphone, housing, loudspeaker, control unit, energy storage device) that are integrated within a single housing. This segmentation allows each component to perform its specific function while being part of a unified portable system that can operate independently outside the vehicle.
Solution Approach 2:
All necessary karaoke components are merged into a single integrated module that functions both as a vehicle-installed system and a portable device. The merging of microphone, loudspeaker, control unit, and energy storage device into one housing creates a self-contained unit that eliminates the need for separate storage compartments.
4Reliability
If the microphone receptacle uses a secure locking mechanism, then the microphone is firmly mounted, but it complicates the removal process
Solution Approach 1:
The microphone receptacle employs a dynamic locking mechanism that adapts its state based on the desired operation. During normal use, the locking mechanism provides secure mounting with high reliability. When removal is needed, the mechanism transitions to an easy-release state, allowing the microphone to be removed without excessive complexity while maintaining firm mounting during operation.
