Solution Overview

Problem

Conventional audio headsets lack flexibility and durability, often compromising comfort, assembly ease, and compatibility with internally routed cords due to limited adjustable components.

Innovation Solution

The headset incorporates a rotatable yoke and arm with a plug that restricts rotation to a suitable range, ensuring secure interlocking and ease of assembly, while maintaining durability and compactness, with a bearing facilitating smooth operation and adhesive or welding for secure fixation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional headsets use fixed connections between headpiece and earpieces, then durability and compactness are maintained, but flexibility and adjustability for comfortable fit are compromised

Engineering Contradiction:

Improveadjustability for comfortable fitVSAvoidstructural complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The headset is divided into separate modular components: headpiece, earpieces, arms, and yokes that can be independently adjusted and connected. This segmentation allows each component to be optimized for specific functions while providing overall adjustability without excessive complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces dynamic elements including rotatable yokes that can pivot to accommodate different head shapes, adjustable arms with multiple degrees of freedom, and movable connection points. These dynamic features enable the headset to adapt to various users while maintaining a relatively simple overall structure through standardized mechanical joints.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If adjustable components are added to conventional headsets, then flexibility and comfort are improved, but durability, compactness, and ease of assembly are compromised

Engineering Contradiction:

ImproveflexibilityVSAvoiddurability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent incorporates pre-engineered stress distribution features in the adjustable components, including reinforced pivot points, distributed load paths through the yoke structure, and predetermined flex zones. These design elements anticipate and compensate for wear and stress concentrations that would otherwise reduce durability in adjustable mechanisms.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The adjustable components utilize controlled parameter changes within specific ranges rather than unlimited adjustment. The yoke rotation is limited to optimized angles, arm adjustments are constrained to ergonomic positions, and connection points are restricted to predetermined locations. This approach provides sufficient flexibility for comfort while maintaining structural integrity and durability.

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If complex adjustable mechanisms are implemented, then comfort and versatility are improved, but ease of assembly and manufacturing simplicity are compromised

Engineering Contradiction:

ImproveversatilityVSAvoidease of assembly

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The adjustable mechanisms are designed with self-aligning features and intuitive connection interfaces that allow assembly without specialized tools or complex procedures. The rotatable yokes and adjustable arms incorporate guide features that automatically position components correctly during assembly, reducing manufacturing complexity while maintaining versatility.

Inventive Principle:

Principle #25Self-service

AI summary

A headset in accordance with an embodiment of the present technology includes a headpiece, an earpiece, a yoke rotatably connected to the earpiece, and an arm extending between the yoke and the headpiece. The yoke at least partially defines a channel including a constriction at which a transverse cross-sectional area of the channel is non-circular. The arm includes a foot at least partially disposed within the channel. The foot is shaped to move through the constriction or be blocked from moving through the constriction depending on a rotational position of the arm relative to the yoke. The headset further includes a plug at least partially disposed within the channel. The plug restricts rotation of the arm relative to the yoke and thereby prevents movement of the foot out of the channel and corresponding separation of the arm from the yoke.
