Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mechanical connection structures are used to protect foldable mobile phones, then protection reliability is improved, but device complexity and production costs increase
Solution Approach 1:
The patent replaces complex mechanical connection structures with a magnetic connection system. The magnetic connection component includes a magnetic sheet integrated into the protector cover that magnetically attracts to the phone case, eliminating the need for buttons, latches, or other mechanical fastening mechanisms while maintaining secure attachment and protection reliability.
Solution Approach 2:
The patent uses magnetic field strength as the connection parameter instead of mechanical engagement forces. By controlling the magnetic attraction force through the magnetic sheet design, the system achieves reliable protection without the structural complexity of mechanical connections, reducing both device complexity and production costs.
2Manufacturing precision
If precise design for specific phone models is implemented, then protection precision is improved, but adaptability decreases
Solution Approach 1:
The patent designs the protector with universal adaptability by using a magnetic connection system that can accommodate different phone models and cases. The magnetic sheet can be positioned and adjusted to work with various phone configurations, allowing a single protector design to serve multiple models while maintaining precise protection through magnetic alignment rather than model-specific mechanical features.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design achieves high production efficiency and low costs by simplifying the production process, while providing adaptable protection for diverse foldable mobile phones, effectively covering folding seams and reducing wear or damage, enhancing user experience and market competitiveness.
Implementation Method 1
The connecting part includes an elastic band and a flexible protective layer... one end of the elastic band is sewn to the edge of the main cover by stitches, the other end of the elastic band and one end of the flexible protective layer are sewn by stitches... When the foldable mobile phone is installed in the mobile phone protector and is in a folded state, the secondary cover and the main cover are arranged opposite to each other up and down, the elastic band is in a stretched state... When the foldable mobile phone is installed in the mobile phone protector and is in an unfolded state, the secondary cover and the main cover are arranged opposite to each other on the left and right, the flexible protective layer is retracted into the main cover through the opening, and the elastic band is in a reset state.
