Over-Ear Headphone Rear Support With Adjustable Earcups
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional over-ear headphones press against the hair on the top portion of the head, making them unsuitable for users with flat head syndrome, and the support structure cannot be adjusted to fit different head shapes.
Innovation Solution
An arc-shaped support structure with a movable abutting assembly positioned at the back of the head, allowing the earcup assemblies to adjust their position relative to the user's head shape, ensuring the support structure does not press against the hair and fits various head shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the support structure is positioned to span the top portion of the head, then the headphones can be worn securely, but the support structure abuts and presses against the hair of the user
Solution Approach 1:
The support structure is inverted from its conventional position spanning the top of the head to a position at the back portion of the head. This inversion relocates the abutting assembly to contact the back of the head instead of the top, thereby eliminating hair pressing while maintaining wearing stability through the arc-shaped geometry that conforms to the head's contour.
Solution Approach 2:
The abutting function is extracted from the main support structure and implemented as a separate abutting assembly positioned at the back of the head. This allows the support structure to provide structural stability while the dedicated abutting assembly handles the contact with the head, preventing hair interference.
2Adaptability or versatility
If the support structure has a fixed arc-shaped configuration, then the headphones can be worn by users with standard head shapes, but users with flat head syndrome cannot wear the headphones
Solution Approach 1:
The earcup assemblies are made movable relative to the support structure through movable connections. This allows the earcups to dynamically adjust their positions to accommodate different head shapes, including flat head syndrome, while the arc-shaped support structure maintains overall stability. The system transitions from a static fixed configuration to a dynamic adjustable configuration.
Solution Approach 2:
The headphone system is segmented into a fixed arc-shaped support structure and movable earcup assemblies. The support structure provides the stable arc-shaped framework, while the separable and movable earcup assemblies can be independently positioned to fit various head shapes, enabling adaptability without compromising structural integrity.
3Adaptability or versatility
If the earcup assemblies are fixed to the support structure, then the structure remains simple, but the headphones cannot be adjusted to fit different head shapes
Solution Approach 1:
The connection between earcup assemblies and support structure is made movable rather than fixed. This dynamic connection enables adjustment for different head shapes while adding only minimal complexity through simple movable joints that allow positional flexibility without requiring complex mechanisms.

AI summary
An over-ear headphone is provided, which includes a support structure, an abutting assembly, two earcup assemblies, and two speaker modules. The support structure is an arc-shaped structure and has two free ends. The abutting assembly is disposed at an inner side of the support structure, and is used for abutting against a back portion of a head of a user. Each one of the earcup assemblies is movably connected to the support structure, and is operable to move toward or away from one of the free ends. Each one of the earcup assemblies includes an earcup that is used for covering an ear of the user. The two speaker modules are disposed in the two earcup assemblies, respectively. Through a configuration of the support structure, the over-ear headphone does not affect a hairstyle of the user.
