Bag Cable Channel with Accessible Ports for Safe Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing luggage and bags with integrated charging functions face inconvenience due to fixed and wear-prone power cables, which are difficult to replace, leading to potential damage and safety issues during charging.
Innovation Solution
A luggage or bag design featuring a cable laying channel with accessible ports on the shoulder strap and body, allowing for easy replacement of the power cable, combined with a waterproof and dust-proof female connector, ensuring safe and reliable charging without opening the bag.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the power cable is fixed and installed in the luggage or bag, then the charging function is integrated and convenient, but the cable becomes wear-prone and difficult to replace
Solution Approach 1:
The cable laying channel is divided into two separate ports: port I on the shoulder strap and port II on the bag body. This segmentation allows the cable to be accessed and replaced at either end independently, facilitating easy replacement while maintaining integrated charging functionality.
Solution Approach 2:
The cable ends are extracted from the interior of the bag to the exterior through the cable laying channel. The male connector is exposed outside port II and the female connector is exposed outside port I, allowing users to replace damaged cable sections without opening the bag or disassembling internal structures.
2Reliability
If the cable laying channel is sealed, then waterproof and dust-proof protection is achieved, but cable replacement becomes difficult
Solution Approach 1:
The cable laying channel is pre-configured with fastening mechanisms at port I that can be opened when cable replacement is needed. This preliminary preparation allows users to access the cable for replacement without compromising the sealed structure during normal use, maintaining both protection and repairability.
3Device complexity
If the power storage space is placed near the joint between shoulder strap and bag body, then cable routing is simplified, but safety risks increase due to heat contact with user
Solution Approach 1:
The cable laying channel extends in three-dimensional space from port I on the shoulder strap, through the joint region, to port II on the bag body. This spatial routing allows the cable to pass near the joint without placing the power storage space in direct contact with the user's body, separating the heat-generating components from the user contact area while maintaining routing efficiency.

AI summary
A case or bag facilitating charging cable change comprises a case or bag body (1), a power cable passage (3), and a power cable (2) arranged in the power cable passage (3). The power cable (2) has a male connector (2.1) and a female connector (2.2). The power cable passage (3) has a port one (3.1) provided on the external surface of the case or bag body (1) and a port two (3.2) provided in the case or bag body (1). The male connector (2.1) of the power cable is provided outside the port two (3.2) of the power cable passage (3) in an exposed manner, and the female connector (2.2) of the power cable is provided outside the port one (3.1) of the power cable passage (3) in an exposed manner. A switchable component (4, 9, 10, 11) enabling the power cable passage (3) to be on or off is provided on the side edge of the port one (3.1) of the power cable passage (3), and a power storage space (6) is provided in the case or bag body (1). Therefore, the power cable (2) in the power cable passage (3) can be conveniently changed, personal injuries caused by power-supply heating due to charging are avoided, and an adequate response time is provided for the user when a combustion accident occurs during charging.
