Elastic Headphone Bracket Adapts to Head Contours
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional headphones often fail to provide comfortable fit due to mismatch between the earphones and the user's head contours, leading to gaps and discomfort, as they rely on hard connecting portions that cannot deform to accommodate different head shapes.
Innovation Solution
The design incorporates elastic portions with concave surfaces and adjustable head mount brackets, allowing the ear cushions to deform and fit various head shapes, ensuring a snug and comfortable fit by eliminating gaps between the ear cushions and the head.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If hard connecting portions are used to maintain structural stability, then the headphone structure remains stable, but the headphones cannot conform to different head shapes, creating gaps and reducing comfort
Solution Approach 1:
The patent applies the dynamics principle by replacing the static hard connecting portions with dynamic elastic portions that can deform and adapt to different head shapes. The elastic portions allow the headphone structure to change its configuration while maintaining connection, enabling both structural stability and adaptability to various user head contours.
Solution Approach 2:
The patent implements parameter changes by transitioning the connecting portions from rigid (hard material) to flexible (elastic material). This material parameter change enables the connecting portions to undergo deformation, allowing the headphones to conform to different head shapes while maintaining structural integrity through the elastic properties of the material.
2Object-affected harmful factors
If ear cushions are thickened to eliminate gaps between headphones and head, then gap reduction is achieved, but the headphone size increases and excessive oppression occurs, reducing comfort
Solution Approach 1:
The patent uses the dynamics principle by making the connecting portions elastic and deformable. This allows the ear cushions to dynamically adjust their position and shape to eliminate gaps between the headphones and head without requiring excessive cushion thickness, thereby avoiding over-oppression and maintaining wearing comfort.
Solution Approach 2:
The patent applies the flexible shells and thin films principle by using elastic connecting portions that can bend and conform to the head's contours. This flexibility enables the ear cushions to make intimate contact with the head surface, eliminating gaps without increasing overall cushion thickness and excessive pressure on the user's head.
3Adaptability or versatility
If ear cushions are thickened to ensure full ear coverage, then tightness is improved, but the overall headphone size becomes larger
Solution Approach 1:
The patent implements the dynamics principle by using elastic connecting portions that allow the ear cushions to adapt their shape and position. This dynamic adjustment capability ensures full ear coverage and tight fit without requiring increased cushion thickness, thereby avoiding an increase in overall headphone volume.

AI summary
A headphone includes two earphone bodies, a head mount bracket, two elastic portions and two ear cushions. The head mount bracket is connected to the two earphone bodies. The two elastic portions are respectively connected to the two earphone bodies, and respectively have a concave surface. The two ear cushions are respectively disposed on the concave surfaces of the two elastic portions and are used to contact a user's ears.
