Earbuds Charging Case Display Through Protected Light-Transmitting Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing TWS earbuds charging cases lack comprehensive information display capabilities, making it difficult for users to accurately determine the battery level and charging status without opening the case, and they are prone to external damage due to limited protection mechanisms.
Innovation Solution
The earbuds charging case features a display module enclosed within a light-transmitting zone, allowing information display through transparent case components, and a touch assembly for intuitive control, enhancing user interaction and protection against external damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display module is directly exposed on the charging case, then the information display function is achieved, but the display is prone to external damage and wear
Solution Approach 1:
The display module is nested within the charging case body, specifically disposed in the mounting cavity formed by the bottom housing and middle housing. This nesting structure allows the display to be protected inside the case while still being viewable through the light-transmitting zone, resolving the contradiction between providing information display and protecting the display from damage.
Solution Approach 2:
The light-transmitting zone acts 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 from external sources of damage, enabling the display to function without being directly exposed to external scratches or friction.
2Reliability
If the case cover is made opaque for protection, then the display is protected, but users cannot view information without opening the case
Solution Approach 1:
The case cover is designed with local quality differentiation: most of the case cover remains opaque for protection and aesthetics, while a specific region (the light-transmitting zone) is made transparent. This allows the cover to provide overall protection while enabling information display at the specific location where the display module is positioned.
Solution Approach 2:
The case cover transitions from a symmetric, uniformly opaque design to an asymmetric design with a transparent light-transmitting zone. This asymmetric feature creates a functional distinction between the protective portions and the information display portion, allowing users to view charging status and battery level without opening the case.
3Measurement precision
If users frequently open the case to check battery status, then accurate information is obtained, but mechanical wear increases
Solution Approach 1:
The light-transmitting zone serves as an intermediary that enables information transfer without physical interaction. Users can obtain accurate battery status and charging information by viewing through the transparent zone, eliminating the need to open the case and thereby reducing mechanical wear on the hinge and connection parts.
Solution Approach 2:
The patent replaces the mechanical action of opening the case with an optical viewing method. Instead of mechanically opening the case to see the display, users can optically view the display through the light-transmitting zone, substituting a mechanical operation with a non-contact optical observation that does not cause wear.
4Reliability
If the display module is enclosed in the mounting cavity, then protection is improved, but the display cannot be viewed from outside
Solution Approach 1:
The display module is nested within the mounting cavity formed by the bottom housing and middle housing, providing physical protection. Simultaneously, the light-transmitting zone in the case cover creates an optical pathway that allows the nested display to be viewed from outside, resolving the contradiction between enclosure for protection and accessibility for viewing.
Solution Approach 2:
The solution moves the display viewing function to another dimension by creating a transparent optical pathway through the case cover. Instead of requiring direct line-of-sight access to the display, the light-transmitting zone enables viewing through the third dimension (through the cover material), allowing the display to be both enclosed and accessible.

AI summary
Disclosed is an earbuds charging case comprising a case body, a case cover and a display. The case body comprises 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 comprises an accommodating recess configured to accommodate earbuds, and a first light-transmitting zone. The case cover is movably connected to the case body, and the case cover comprises a second light-transmitting zone. The display is disposed in the mounting cavity or on the middle housing. 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 content of the display is transmitted through the first light-transmitting zone and the second light-transmitting zone to be displayed on the display.
