Rotating Earphone Compartment in Charging Box
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional charging boxes make it difficult to remove earphones due to their design, which can be hindered by sweat on the user's fingers, affecting the user experience.
Innovation Solution
A charging box design featuring a lower housing with a rotatable inner compartment that protrudes upward when the upper housing is opened, facilitated by a connecting rod structure and elastic components, allowing the earphone to be easily extracted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the lower housing has a certain depth to accommodate the earphone, then the earphone can be securely stored, but it becomes difficult to take out the earphone when there is sweat on the user's fingers
Solution Approach 1:
The patent applies the dynamics principle by making the lower inner housing rotatable rather than fixed. When the upper housing is opened, the transmission structure drives the lower inner housing to rotate, causing the earphone slot to protrude upward. This dynamic transformation allows the earphone to be easily accessed without requiring deep manual insertion into the deep lower housing, solving the contradiction between secure storage and easy removal.
2Reliability
If the earphone slot is positioned deep in the lower housing, then the earphone is securely held, but the user experience deteriorates when fingers are sweaty
Solution Approach 1:
The rotatable lower inner housing transforms the static deep earphone slot into a dynamically accessible position. Upon opening the upper housing, the rotation mechanism brings the earphone slot upward, allowing users to easily grasp the earphone without dealing with sweat on their fingers, thus maintaining security while improving user experience.
Solution Approach 2:
The transmission structure performs the preliminary action of rotating the lower inner housing automatically when the upper housing is opened. This preliminary movement positions the earphone slot in an accessible location before the user attempts to remove the earphone, preventing the need for fingers to dig into the deep housing.
3Device complexity
If a traditional fixed lower housing is used, then the structure is simple, but the earphone cannot be easily removed due to the deep housing design
Solution Approach 1:
The patent introduces a rotatable lower inner housing connected via a transmission structure, transforming the simple fixed housing into a dynamic system. This adds complexity to the housing structure but significantly improves earphone removal ease by automatically bringing the earphone slot to an accessible position when the upper housing is opened.
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
The design enables smooth and easy removal of the earphone by rotating the inner compartment, reducing the risk of getting stuck and improving user experience.
Implementation Method 1
an upper housing elastic component is disposed between the lower housing and the upper housing, such that the upper housing has a tendency of closing movement
Implementation Method 2
a lower inner housing elastic component is disposed between the lower inner housing and the lower housing, such that the lower inner housing has a movement tendency to retract to an inner of the lower housing
