Semi-Open Earphone Case for Easier Access and Stable Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless earphone charging cases with profiled sink grooves have deep grooves that require a large traveled distance for earphone insertion and removal, and a flappable cover with a limited opening angle can hinder the process, restricting the earphone's degree of freedom and user experience.
Innovation Solution
The earphone case features a semi-open design with a lower housing having first and second accommodating grooves with top and side openings, and attraction members to stabilize the earphones, allowing for convenient insertion and removal from multiple directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a profiled sink groove is used to accommodate the earphone, then the earphone stability during charging is improved, but the traveled distance for insertion and removal increases and the degree of freedom is restricted
Solution Approach 1:
The accommodating groove is segmented into multiple opening directions (top opening and side opening) instead of a single deep groove, allowing earphones to be inserted or removed from different directions to reduce traveled distance and improve ease of operation while maintaining stability through the groove structure
Solution Approach 2:
The groove design transitions from a single-direction deep groove to a multi-dimensional structure with both top and side openings, enabling earphone access from multiple spatial dimensions and reducing the linear traveled distance required for insertion and removal
2Volume of moving object
If a flappable cover with limited opening angle is used, then the case structure is compact, but the earphone insertion and removal process is hindered
Solution Approach 1:
The cover structure is segmented to provide multiple access paths (top opening and side opening) rather than requiring full opening of a flappable cover, allowing earphone access with a smaller opening angle and maintaining compact case structure while improving ease of operation
3Stability of the object's composition
If attraction members are added to stabilize earphones, then the earphone positioning stability is improved, but the device complexity increases
Solution Approach 1:
Attraction members (magnetic elements) are integrated into the case structure to automatically attract and position earphones containing magnetic elements, achieving stable positioning through self-service magnetic attraction without requiring complex mechanical locking or adjustment mechanisms
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances user experience by simplifying the process of taking and placing earphones, reducing the traveled distance, and improving the stability of the earphones within the case, while maintaining a compact structure.
Implementation Method 1
The lower housing comprises a plurality of attraction members corresponding to each of the first accommodating groove and the second accommodating groove, the attraction members corresponding to the first accommodating groove are configured to attract a stem of the left earphone
