Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The increasing thickness of electronic devices to accommodate larger screens and thinner designs creates a challenge in coordinating the layout of headset jacks, leading to space inefficiencies and aesthetic issues.

Innovation Solution

A connection member with a pin that communicates with a terminal near the end of a headset plug, reducing the insertion length and depth of the headset jack, thereby saving space by allowing the headset plug to be partially inserted and using pins to connect with contact points within the jack.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the electronic device is made thinner and the screen is made larger, then the user experience is improved, but the space for coordinating the headset jack layout becomes insufficient

Engineering Contradiction:

Improvedevice thicknessVSAvoidheadset jack layout space

Core Design Contradiction:

Volume of moving objectVSArea of stationary object

Solution Approach 1:

The headset plug is divided into two functional parts: the insulation-exposed section that contacts the connection member, and the remaining plug body. This segmentation allows the plug to make electrical contact without requiring full insertion depth, thereby reducing the space needed for the headset jack in the electronic device.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A connection member is introduced as an intermediary component between the headset plug and the headset jack. The connection member includes a contact portion that touches the exposed insulation of the plug and a connection portion that interfaces with the jack, effectively mediating the connection and reducing the required insertion depth.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the headset plug uses standard diameter (2.5mm or 3.5mm), then compatibility is improved, but the insertion depth required increases

Engineering Contradiction:

Improveplug compatibilityVSAvoidinsertion depth

Core Design Contradiction:

Adaptability or versatilityVSLength of moving object

Solution Approach 1:

Instead of requiring the entire headset plug to be inserted into the jack for connection, the invention uses only a partial insertion approach where the exposed insulation portion makes contact with the connection member. This partial action achieves the necessary electrical connection without the excessive insertion depth that would be required for standard plugs.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

The present disclosure relates to a connection member for connecting a headset plug with an electronic device, a headset jack of the electronic device and the electronic device. The connection member comprises a pin, wherein the pin communicates with a terminal positioned near an end portion of the headset plug when the connection member is connected with the headset plug. The connection member disclosed in the present disclosure can reduce the length of the headset to be inserted into the headset jack, and reduce the depth of the headset jack, thereby saving space in the electronic device configured with the headset jack.
