Adjustable Over-Ear Headphone Cushions for Eyewear
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing over-ear headphone cushions are uncomfortable to use with eyewear frames as they press the temples into the head, causing discomfort and compromising sound quality.
Innovation Solution
An adjustable over-ear headphone cushion with a ratcheting system allowing vertical adjustment of upper and lower cushions to accommodate eyewear frames without losing sound quality, featuring a pair of U-shaped cushions connected via a ratcheting mechanism and a click-in structure for compatibility with modern headphones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing over-ear headphone cushions are used, then sound quality is maintained, but comfort is compromised when wearing eyewear frames due to pressure on the temples
Solution Approach 1:
The headphone cushion incorporates a ratcheting mechanism that allows the upper cushion to be dynamically adjusted to multiple vertical positions relative to the lower cushion. This enables the cushion to adapt its configuration based on whether the user is wearing eyewear or not, resolving the contradiction between maintaining sound quality and ensuring comfort with eyewear.
Solution Approach 2:
The headphone cushion is divided into two separate cushions (upper and lower) that can be independently positioned. The upper cushion can be adjusted vertically relative to the lower cushion through the ratcheting mechanism, allowing the temple space to be segmented and accommodated when needed, while maintaining the complete seal when not wearing eyewear.
2Ease of operation
If the upper and lower cushions are spaced apart to accommodate eyewear temples, then comfort is improved, but sound quality may be compromised due to reduced seal
Solution Approach 1:
The ratcheting mechanism enables dynamic adjustment of the upper cushion position, allowing users to switch between a sealed configuration (for sound quality) and a spaced configuration (for comfort with eyewear). The system maintains reliability by providing the sealed configuration as an available state when needed.
Solution Approach 2:
The vertical position parameter of the upper cushion is made adjustable through the ratcheting mechanism. By changing this parameter between different discrete positions, the system can optimize both the seal quality and the accommodation of eyewear temples as needed.
3Ease of manufacture
If a fixed cushion design is used, then manufacturing is simple, but adaptability to different eyewear sizes is lost
Solution Approach 1:
The ratcheting mechanism provides a relatively simple mechanical solution that enables multiple adjustable positions. This maintains manufacturing simplicity while providing adaptability to different eyewear sizes through the adjustable vertical positioning of the upper cushion.
Solution Approach 2:
The adjustable mechanism serves multiple functions: it accommodates various eyewear sizes, maintains seal for sound quality, and provides comfort options. This multi-functionality is achieved through a single ratcheting system that handles all adjustment needs.

AI summary
An adjustable over-ear headphone cushion for comfortably accommodating eyewear frames without losing sound quality may include an upper cushion and a lower cushion attached to the upper cushion with a ratcheting system. The upper cushion and the lower cushion may be vertically adjusted with respect to one another from a mated configuration to a spaced apart configuration, and the upper cushion and the lower cushion together form a substantially O-shaped headphone cushion configured to be removably attached to a headphone.
