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

VSEngineering 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

Engineering Contradiction:
ImproveIndependent usabilityVSAvoidInstallation complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #5Merging (Combining)

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Engineering Contradiction:
ImproveInstallation effortVSAvoidSafety risks from protruding components
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

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.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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

Engineering Contradiction:
ImprovePortable independent useVSAvoidComponent integration
Core Design Contradiction:
Adaptability or versatilityVSDevice 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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #5Merging (Combining)

4Reliability

If the microphone receptacle uses a secure locking mechanism, then the microphone is firmly mounted, but it complicates the removal process

Engineering Contradiction:
ImproveMicrophone mounting securityVSAvoidMicrophone removal
Core Design Contradiction:
ReliabilityVSEase of operation

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.

Inventive Principle:
Principle #15Dynamics
