Embedded Charging Cable Layout for Compact Mobile Power Packs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile power supply devices face challenges in compact design and convenient usage, particularly in accommodating flexible data lines and latch connections for various electrical tools, which limits their usability and portability.
Innovation Solution
A mobile power supply device with a housing that includes a cell, circuit board, and a data line embedded in a U-shaped or S-shaped configuration on a flat surface, along with latch slots and tool discharge terminals, allowing for flexible bending and embedding to fit within limited spaces and facilitate connections to electrical tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the data line is made flexible and embedded in a U-shaped or S-shaped configuration, then the device becomes more compact and easier to carry, but the data line arrangement becomes more complex
Solution Approach 1:
The data line is configured in a U-shaped or S-shaped curved arrangement embedded in the housing, allowing flexible bending while maintaining a compact form factor. This curved configuration enables the data line to fit within limited space without requiring additional external routing.
Solution Approach 2:
The data line is embedded within the housing structure, nesting the flexible cable inside the device body. This nesting approach conceals the complex arrangement within the housing, presenting a clean external appearance while accommodating the flexible internal configuration.
2Adaptability or versatility
If multiple interface types are integrated into the housing, then the device becomes more versatile, but the housing structure becomes more complex
Solution Approach 1:
The housing integrates multiple discharge interfaces including USB Type-C and Lightning interfaces, allowing the mobile power supply to charge various types of portable electronic devices. This multi-functional design enables a single device to serve multiple charging purposes.
Solution Approach 2:
Multiple interface types are merged into a single housing structure, with the data line connecting to different interface endpoints within the same device. This combining approach consolidates multiple functions into one integrated unit rather than requiring separate devices.
3Reliability
If the data line is fixedly connected to the housing, then the connection becomes more reliable, but the flexibility for bending is reduced
Solution Approach 1:
The data line has different properties in different sections: one end is fixedly connected to the circuit board for reliable electrical connection, while the embedded portion in the housing allows flexible bending. This local differentiation of connection rigidity versus flexibility resolves the contradiction between stable connection and bending capability.

AI summary
A mobile power supply device includes a housing; a cell and a circuit board that are arranged in the housing; and a data line. One end of the data line is electrically connected to the circuit board and is fixedly connected to the housing. The housing has at least one flat surface. The data line is suitable for being flexibly bent and is at least partially embedded in the flat surface in a U-shape or an S-shape. The mobile power supply device with the structural design is convenient to use and carry.
