Wearable USB Sheath with Dust Cap for Convenient Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of portable digital devices face inconvenience when batteries run low, as existing solutions require opening bags or luggage to charge devices, lacking convenience and protection from environmental factors.
Innovation Solution
A sheath integrated into wearable or carried items, such as bags, clothing, and accessories, featuring a USB charging interface with waterproof and dust-proof design, allowing charging without opening the item and incorporating Bluetooth anti-lost and GPS features for location tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the USB charging interface is integrated inside the bag or luggage, then the device is protected from environmental factors, but the user must open the bag to charge the device, reducing convenience
Solution Approach 1:
The USB charging interface is extracted from the interior of the bag and extended outward through an opening in the bag body. This allows the charging interface to remain protected within the bag structure while being accessible from the outside, eliminating the need to open the bag for charging.
Solution Approach 2:
A USB extension cable serves as an intermediary element, with its male connector inside the bag connected to the power storage device and its female connector extending outside the bag through an opening. This intermediary allows external devices to be charged without compromising the protective enclosure of the bag.
2Ease of operation
If the USB cable is extended outside the bag, then charging convenience is improved, but the cable may be exposed to dust and water, reducing reliability
Solution Approach 1:
The opening in the bag body where the USB extension cable passes through is equipped with a dust cap that can be opened or closed. This allows the opening to have different properties (open for charging access, closed for dust and water protection) based on operational needs, maintaining local quality adaptation.
Solution Approach 2:
The dust cap on the opening is designed to be dynamically adjustable - it can be opened when charging is needed and closed when protection is needed. This dynamic element allows the system to adapt between convenience and protection modes, preventing dust and water ingress while maintaining charging accessibility.
3Object-affected harmful factors
If the female connector is covered inside the bag, then protection is improved, but charging operation becomes complex requiring opening the bag
Solution Approach 1:
The female connector of the USB extension cable is extracted from the bag interior and positioned outside through an opening. This extraction allows the connector to remain protected within the bag structure while being externally accessible, reducing charging operation complexity to a simple plug-and-play action without requiring bag opening.
4Ease of operation
If the USB extension cable is permanently exposed outside the bag, then charging accessibility is improved, but the bag structure becomes more complex
Solution Approach 1:
Instead of permanently exposing the USB extension cable, a dust cap is added to the opening that allows selective access. This local modification maintains the bag's protective structure while providing charging accessibility when needed, avoiding the need for complex permanent openings or exposed cable structures.

AI summary
A sheath for convenient charging having a left side, a right side and a top side, a first closed end, a second open end and a surrounding bottom portion surrounding at least a portion of the sides and ends of the sheath. At least a portion of the sheath extends above an outer surface of a body, wherein the body has an inner surface, an outer surface and an opening between the inner surface and the outer surface. The sheath is at the opening and the sheath receives a female end of a USB cable having four sides, an operative end, a cord end and a cord. The operative end of the female end of the USB cable is retained in the second open end of the sheath and the cord end of the female end of the USB cable is retained in the first closed end of the sheath to provide the female end of the UBS cable in a flat position with the operative end of the female connector being uncovered and above the outer surface of the body and the cord of the female end goes through the opening between the inner surface and the outer surface and the surrounding bottom portion is attached to a portion of the body.
