Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a modular back plate design with detachable components is used, then the adaptability and individualization of the phone case is improved, but the device complexity increases
Solution Approach 1:
The back plate is divided into multiple detachable modeling modules that can be independently selected and combined. Each module can be separately manufactured and then assembled on the ferromagnetic back plate, allowing users to create customized designs while maintaining a relatively simple base structure.
Solution Approach 2:
The ferromagnetic back plate serves multiple functions: it provides structural support, enables magnetic attachment of modeling modules, and offers a standardized interface for modular components. This universal base plate can accommodate various types of modeling modules for different design preferences.
2Ease of operation
If magnetic attraction structures are added to facilitate easy opening and closing, then the ease of operation is improved, but the device complexity and aesthetic appearance deteriorate
Solution Approach 1:
The mechanical snap-fit or button-based closure system is replaced with a magnetic attraction system. The magnetic strip and iron strip provide automatic alignment and secure closure through magnetic force, eliminating the need for complex mechanical latches or buttons while maintaining ease of operation.
Solution Approach 2:
A thin magnetic strip is integrated into the case structure, providing the closing mechanism without adding significant bulk or complexity. The magnetic strip can be concealed within the case design, minimizing impact on aesthetic appearance.
3Reliability
If elastic pressing columns are used to fix the back plate, then the stability of fixation is improved, but the device complexity increases
Solution Approach 1:
The elastic pressing columns are integrated directly into the case body structure, allowing the case to automatically adjust and adapt to different back plate thicknesses. The elastic material provides self-regulating pressure to ensure stable fixation without requiring additional adjustment mechanisms.
Solution Approach 2:
The elastic pressing columns utilize material elasticity to change their physical state between compressed and relaxed conditions. This parameter change allows the same structure to provide consistent fixation force across varying back plate thicknesses while maintaining a simple overall design.

Function Achieved in This Case
Enables users to create diverse and personalized designs, facilitating easy replacement and showcasing individuality while providing protection and convenience.
Implementation Method 1
A pair of magnetic attraction structures is arranged on a side of the outer case and a side of the inner case opposite to the rotating shaft, so that the outer case can be opened and closed more conveniently
Implementation Method 2
A front side of a bottom plate of the outer case is provided with an elastic pressing column. The back plate is arranged in an interlayer between the outer case and the inner case and is pressed against a rear side of the inner case by the pressing column

AI summary
A modular individualized phone case includes a case body, a back plate and a modular modeling component. The back plate is detachably arranged in the case body, the back plate is a ferromagnetic metal plate, and the modular modeling component is attracted and fixed onto a rear side surface of the back plate. The modular modeling component includes multiple modeling modules which can be combined to form different looks. The modeling modules are magnetic attraction sheets. The modeling modules are attracted on the rear side of the back plate and combined to form individualized designs, and then the back plate is put into the case body. The modeling modules of the individualized design can be exhibited through the transparent case body. As such, various different rear-view looks (depending on the number of modeling modules, the more the number is, the more diverse the overall look is) can be obtained.
