Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a separate capacity expansion module is added to the mobile phone case, then storage capacity is expanded, but the structure becomes complex and operation becomes inconvenient
Solution Approach 1:
The patent combines the capacity expansion module with the mobile phone case into a single integrated structure. The case body (1) incorporates a cavity that directly receives the mobile phone, while the combined male-female connector (2) is embedded within the case structure itself. This merging eliminates the need for separate expansion modules and reduces operational complexity.
Solution Approach 2:
The mobile phone case is designed to perform multiple functions simultaneously: it protects the mobile phone, provides storage expansion capability, and enables charging through the integrated combined connector. The case body serves both as a protective enclosure and as a housing for the storage expansion device, while the combined connector integrates both charging and data transfer functions.
2Quantity of substance
If additional interfaces are added to the mobile phone case for storage expansion, then storage capacity is expanded, but structural strength is reduced and operation convenience is affected
Solution Approach 1:
The combined male-female connector (2) integrates both male and female connector components into a single unified structure that is embedded within the case body (1). This merging reduces the number of separate interfaces and components, thereby maintaining structural strength while providing storage expansion capability.
3Quantity of substance
If a separate expansion module is used for storage expansion, then storage capacity is increased, but charging and data transfer functions are interfered with
Solution Approach 1:
The combined male-female connector (2) integrates both charging and storage expansion functions into a single unified interface structure. The male connector portion connects to the mobile phone's charging port, while the female connector portion provides the interface for the capacity expansion module. This integration ensures that charging and data transfer functions operate reliably without interference from separate expansion modules.
Solution Approach 2:
The combined male-female connector (2) serves as an intermediary structure that mediates between the mobile phone's charging port and the capacity expansion module. It provides a stable connection interface that ensures reliable charging and data transfer while enabling storage expansion functionality.
4Ease of manufacture
If ordinary storage technology (eMMC) is used in the storage module, then manufacturing cost is reduced, but transfer rate is low and power consumption is high
Solution Approach 1:
The patent specifies using UFS (Universal Flash Storage) memory chips instead of ordinary eMMC storage technology. This parameter change in storage technology provides significantly higher data transfer rates and lower power consumption while maintaining reasonable manufacturing costs. The UFS memory chip (3) is integrated into the capacity expansion module, providing fast read and write speeds.

AI summary
An integrated storage expansion mobile phone case includes a mobile phone case body and a combined male-female connector, where a cavity for accommodating a mobile phone is provided at an interior of the mobile phone case body, a through hole is provided in a side wall of the mobile phone case body, and the position of the through hole is aligned with the position of a mobile phone charging port. The combined male-female connector passes through and is fixedly arranged in the through hole, with a male connector of the combined male-female connector being located at the interior of the mobile phone case body, and a female connector of the combined male-female connector being flush with an outer wall of the mobile phone case body. A memory chip, a current controller, and a circuit connector are embedded in the mobile phone case body close to the through hole.
