Earphone Storage Case Positioning Cavity for Stable Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bluetooth earphones in earphone cases are prone to shifting during frequent vibrations, leading to collisions and incomplete charging contacts, which affect user experience.
Innovation Solution
A storage case with an upper and lower housing that define an accommodating cavity, featuring first and second positioning portions to securely hold the earphone, including a first positioning region and a second positioning region that cooperatively form a positioning cavity to prevent shifting and improve charging stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the earphone is placed in the earphone case without positioning structures, then the case structure is simple, but the earphone shifts during vibrations causing collisions and incomplete charging contacts
Solution Approach 1:
The positioning structure is divided into two independent positioning portions: a first positioning portion that limits the battery portion of the earphone, and a second positioning portion that limits the body portion. This segmentation allows each portion to be optimized independently while working together to prevent earphone shifting during vibrations, ensuring stable charging contacts without excessive structural complexity.
Solution Approach 2:
Different positioning portions are designed with different structural characteristics tailored to their specific functions. The first positioning portion features a curved surface that conforms to the cylindrical battery portion, while the second positioning portion has a flat or curved surface for the body portion. This local quality optimization ensures effective limitation of each earphone component without requiring a uniformly complex structure throughout the entire case.
2Manufacturing precision
If positioning portions are added to the earphone case, then the earphone positioning stability is improved, but the manufacturing complexity increases
Solution Approach 1:
The first and second positioning portions are integrated into a single earphone case structure, forming a unified positioning system. This merging approach allows the positioning functions to work cooperatively to achieve high positioning precision while avoiding the need for separate detachable positioning components, thereby simplifying the manufacturing process and reducing assembly steps.
Solution Approach 2:
Instead of adding complex external positioning mechanisms to the case, the invention inverts the approach by creating positioning portions that are formed directly within the case structure itself. The positioning portions are molded as integral parts of the case housing, which simplifies manufacturing compared to attaching separate positioning components, while still achieving precise earphone limitation.

AI summary
A storage case includes an upper housing and a lower housing. They cooperatively define an accommodating cavity for an object. The lower housing defines a mounting recess. The storage case further includes a first positioning portion and a second positioning portion. The first positioning portion is on an inner surface of the upper housing facing towards the lower housing and protrudes towards the lower housing, and is adjacent to a first part of the mounting recess. The first positioning portion and the first part of the mounting recess constitute a first positioning region. The second positioning portion is on the inner surface of the upper housing facing towards the accommodating cavity. The second positioning portion and a second part of the mounting recess constitute a second positioning region. The first positioning region and the second positioning region cooperatively define a positioning cavity for the object.
