Wireless Earbud Charging Case Detachable Hinge for Dust Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rotating-type charging cases for wireless earbuds suffer from dust and contamination entry due to a rotation gap, leading to maintenance issues and poor user experience.
Innovation Solution
A detachable mechanism with an elastic snap-fit member and rotating shaft allows the outer and inner housings to detach or snap-fit, enabling easy cleaning and maintenance, while a bushing mechanism enhances stability and noise reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a rotating-type charging case is used to accommodate wireless earbuds, then the charging case can charge the wireless earbuds and be easy to carry, but dust or contamination easily enters the rotation gap between the outer housing and inner housing, causing maintenance issues and poor user experience
Solution Approach 1:
The charging case is divided into separable components: an outer housing and an inner housing that can be detached from each other. The detachable mechanism includes a rotating base with snap-fit members that engage with corresponding slots in the outer housing, allowing the case to be opened into separate parts for cleaning while maintaining a compact closed form for portability.
2Volume of moving object
If a rotating-type charging case is used, then the charging case provides compact accommodation, but rotation stunning and adverse effects on appearance are easily caused after long-term use
Solution Approach 1:
The charging case employs a dynamic detachable mechanism with a rotating base that can rotate relative to the outer housing. The rotating base includes snap-fit members that engage with slots in the outer housing, providing stable connection during normal use while allowing easy detachment when needed. This dynamic structure maintains compactness during rotation while ensuring reliability through the snap-fit engagement system.
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
Facilitates cleaning and maintenance, improves user experience by preventing dust entry and reducing rotation noise, and ensures stable operation.
Implementation Method 1
an elastic snap-fit member is disposed on the rotating base. when the rotating base rotates by a first angle, the elastic snap-fit member rotates out of the slot, and the outer housing assembly and the inner housing are detachable; or when the rotating base rotates by a second angle, the elastic snap-fit member and the slot are snap-fitted

AI summary
Provided are a charging case for wireless earbuds and a wireless earbud assembly. The charging case for wireless earbuds includes an outer housing assembly, an inner housing, and a detachable mechanism. The outer housing assembly and the inner housing are configured to rotate relative to each other, and a slot is disposed in the outer housing assembly. The detachable mechanism includes a rotating base, an elastic snap-fit member, and a rotating shaft. The rotating base is at least partially exposed outside the outer housing assembly, the rotating shaft is connected to the rotating base and is rotatably connected to the inner housing, and the elastic snap-fit member is disposed on the rotating base.
