Earbud Charging Case Display Through a Closed Protective Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing earbud charging cases lack comprehensive information display capabilities, making it difficult for users to accurately determine the battery level and charging status of TWS earbuds, and they are prone to damage due to frequent opening and closing.
Innovation Solution
An earbud charging case with a display module and light-transmitting zones that allow information display without opening the case, combined with a touch assembly for personalized settings, enhancing user interaction and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display module is exposed outside the case body, then the user can easily view information, but the display module is prone to damage from external scratches and friction
Solution Approach 1:
The display module is nested inside the case body within the mounting cavity, protected by the case structure. The light-transmitting zone acts as a window that allows viewing without direct exposure, effectively nesting the vulnerable component within a protective shell while maintaining functionality.
Solution Approach 2:
The light-transmitting zone serves as an intermediary element between the display module and the external environment. It allows light and information to pass through while physically separating the display module from external damaging factors such as scratches and friction.
2Loss of information
If the case cover is frequently opened and closed to view information, then the user can access detailed data, but the earbud charging case is prone to damage and wear
Solution Approach 1:
The system performs preliminary action by displaying essential status information (battery level, charging status) through the light-transmitting zone before the user needs to open the case. This allows users to obtain critical information without performing the action of opening the case, thereby preventing unnecessary mechanical wear.
Solution Approach 2:
The display module provides real-time feedback about earbud and case status through the light-transmitting zone. Users can monitor battery levels and charging states without opening the case, reducing the frequency of opening/closing operations and extending the mechanical life of the hinge and case structure.
3Loss of information
If comprehensive status information is displayed, then the user's understanding of device status is improved, but the device complexity increases
Solution Approach 1:
The display module serves multiple functions: displaying battery level, charging status, and potentially other device states. This single multi-functional component replaces what would otherwise require multiple separate indicators or display elements, providing comprehensive information while maintaining relatively simple system architecture.

AI summary
Disclosed is an earbud charging case including a case body, a case cover and a display module. The case body includes a bottom housing and a middle housing connected to the bottom housing. The middle housing and the bottom housing enclose a mounting cavity. The middle housing is provided with an accommodating recess configured to accommodate earbuds; and a first light-transmitting zone. The case cover is movably connected to the case body to close and open the case body, and the case cover is provided with a second light-transmitting zone. The display module is disposed in the mounting cavity or on the middle housing, and corresponds to a position of the first light-transmitting zone. When the case body is closed by the case cover, a position of the second light-transmitting zone corresponds to the position of the first light-transmitting zone, and display content of the display module is able to transmit through the first light-transmitting zone and the second light-transmitting zone to be displayed outside. This enables the user to view the information displayed on the display module without opening the case cover, which improves the user's experience, so that the user can quickly obtain the information displayed on the display module without frequently opening and closing the earbud charging case.
