Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing earphones often suffer from discomfort and instability due to inadequate fitting and pressure distribution when worn, affecting user experience.
Innovation Solution
The earphone design includes adjustable components such as speaker assemblies, function assemblies, and ear hooks that allow for customizable angles and connections, along with features like elastic hooks and adhesive layers to enhance fit and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If fixed structure (ear hook or rear hook) is used to fix earphones on the ear circumference, then stability is improved, but comfort deteriorates due to excessive pressure and inadequate fitting
Solution Approach 1:
The patent applies dynamics by making the connection between speaker assembly and function assembly adjustable rather than fixed. The speaker assembly can rotate relative to the function assembly around a rotation axis, allowing the attitude angle to be dynamically adjusted to fit different ear shapes and sizes, thereby maintaining stability while improving comfort
Solution Approach 2:
The patent changes the parameter of the attitude angle between the speaker assembly and function assembly. By adjusting this angle within a specific range, the earphone can adapt to different ear geometries, distributing pressure more evenly and improving both stability and comfort simultaneously
2Object-affected harmful factors
If adjustable components are added to allow customizable angles and connections, then comfort is improved, but device complexity increases
Solution Approach 1:
The patent segments the earphone into distinct functional modules: speaker assembly, function assembly, and ear hook, connected through a rotation mechanism. This segmentation allows independent adjustment of each module while maintaining overall simplicity, improving comfort without excessive complexity
Solution Approach 2:
The rotation mechanism provides a single degree of freedom for adjustment, making the system dynamically adaptable without requiring complex multi-axis adjustment mechanisms. This keeps the device relatively simple while achieving improved comfort through attitude angle adjustment
