Solution Overview

Problem

Conventional earphones for joggers face issues such as wire interference during movement, the need to stop jogging to adjust music, and battery power limitations that render devices inoperable during charging.

Innovation Solution

An earphone set with a connector linking two earphones, a memory module for audio data, and a power management module to prevent short circuits, along with controllers for volume adjustment and sound manipulation, allowing for wireless operation and interchangeable components for continuous use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If wireless technology is used to eliminate wires connecting earphones to music player, then movement interference is reduced, but separate power supply is required for earphone set and music player

Engineering Contradiction:
Improvewire interferenceVSAvoidpower supply system
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent merges the power supply systems by integrating a power supply module into the earphone set that can charge from the music player's power output. This combines what would otherwise be separate power systems into a unified architecture where the earphones can be charged during connection to the music player, eliminating the need for completely independent power management.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The connector serves multiple functions: it provides audio signal transmission, power transmission for charging the earphone battery, and data communication. This multi-functionality reduces the need for separate dedicated power supply components in the wireless earphone system.

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

2Ease of operation

If earphones are integrated with controllers for volume and music control, then ease of operation is improved, but adaptability to different music players is restricted

Engineering Contradiction:
Improvemusic controlVSAvoidcompatibility
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The controller in the earphone set is designed with universal compatibility, supporting multiple control protocols and communication interfaces. This allows the same controller hardware to work with different music player devices while maintaining full control functionality for volume, track selection, and playback control.

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

Solution Approach 2:

The control functionality is segmented into the earphone unit itself rather than being integrated into the music player. This separation allows the controller to be designed independently with universal protocols, enabling it to adapt to different music players without restricting compatibility.

Inventive Principle:
Principle #1Segmentation

3Weight of moving object

If portable music player is integrated with rechargeable battery, then portability is improved, but productivity is reduced when battery needs charging

Engineering Contradiction:
ImproveportabilityVSAvoidusage continuity
Core Design Contradiction:
Weight of moving objectVSProductivity

Solution Approach 1:

The earphone set maintains continuous music playback capability even when the music player battery is depleted. The earphone's own power supply module ensures that music can continue playing during the player's charging period, eliminating interruptions and maintaining productivity.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

When the music player battery is exhausted, the system transitions to using the earphone's battery power. The earphone effectively becomes the primary power source during this period, allowing the user to continue using the system without interruption until the player battery is recharged.

Inventive Principle:
Principle #34Discarding and recovering

4Ease of operation

If memory module is placed in connector for audio data storage, then ease of operation is improved, but device complexity is increased

Engineering Contradiction:
Improvedata accessVSAvoidconnector structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The memory module is merged with the connector assembly rather than being a separate component in the earphone or music player. This integration allows the connector to serve dual purposes: physical/electrical connection and local audio data storage, simplifying the overall system architecture while maintaining ease of operation.

Inventive Principle:
Principle #5Merging (Combining)
