Solution Overview

Problem

Existing electronic devices lack intuitive control mechanisms for multimedia functions when earphones are connected, as many earphones do not provide volume keys or other control keys, requiring changes in the device's structure or software to manage these functions.

Innovation Solution

A rotatable earphone plug with conductive patterns on both the plug and the connecting member of the electronic device allows for intuitive control of functions like volume adjustment, screen brightness, and channel search by detecting the alignment and rotation of the plug, using a processor to control the device's functions accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional earphone interfaces are used without control keys, then the earphone structure remains simple, but the electronic device lacks intuitive control capability for multimedia functions

Engineering Contradiction:
Improvecontrol capabilityVSAvoidinterface structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The earphone plug itself serves as the control interface through its rotatable structure. The plug's rotation angle directly controls electronic device functions without requiring separate control keys or buttons on the earphone body, making the plug self-sufficient for control purposes

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The invention utilizes rotation angle as a variable parameter to control different functions. By detecting the angular position of the rotated plug, the system distinguishes between different control commands (volume up/down, playback control, etc.), transforming a simple mechanical rotation into multiple functional controls

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If additional control keys are added to earphones, then control functionality is improved, but manufacturing complexity and cost increase

Engineering Contradiction:
Improvecontrol functionalityVSAvoidmanufacturing complexity
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The existing earphone plug, originally designed solely for audio connection, is赋予 additional control functions through its rotatable capability. This single component serves dual purposes: audio transmission and control input, eliminating the need for separate control keys and simplifying manufacturing

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

Solution Approach 2:

The control functionality is extracted from the earphone body and concentrated in the plug itself. By moving the control interface to the plug, the design removes the need for additional control keys on the earphone housing, reducing manufacturing steps and assembly complexity

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of operation

If the electronic device requires software or structure changes to control functions, then control capability is enhanced, but device complexity increases

Engineering Contradiction:
Improvecontrol capabilityVSAvoidsoftware or structure changes
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The invention replaces complex software-based control schemes with a simple mechanical rotation detection system. The plug's physical rotation position is directly detected by contact points, providing intuitive control without requiring complex software interpretation or additional hardware modifications

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
