Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws and welding are used to fix structural parts, then the structural strength and stability are improved, but the ease of repair and disassembly deteriorates
Solution Approach 1:
The hinge module is divided into separable components including a first body, second body, latch, shaft member, and screw member. This segmentation allows the structural parts to be divided into modular units that can be easily disassembled and reassembled while maintaining structural integrity during use.
Solution Approach 2:
The hinge module transitions from a fixed state (when screw member locks latch and shaft member) to a movable state (when unlocked). The dynamic design allows the connection between first body and second body to be changeable between locked and unlocked states, enabling easy disassembly while maintaining strength during operation.
2Stability of the object's composition
If traditional fixed connection methods are used, then the device stability is improved, but the adaptability for maintenance and regeneration deteriorates
Solution Approach 1:
The hinge module serves multiple functions: it provides stable connection during normal use, enables easy disassembly for maintenance, and allows regeneration of components. The universal design of the latch and screw member mechanism can be applied to various foldable electronic devices, improving adaptability for different maintenance scenarios.
3Ease of operation
If exposed screw member design is used, then the ease of operation for disassembly is improved, but the device complexity increases
Solution Approach 1:
The screw member is extracted from the internal structure and exposed on the side surface of the second body. This extraction allows users to directly access and operate the screw member for disassembly without needing to disassemble other components first, improving ease of operation while the modular design keeps the overall complexity manageable.

AI summary
A foldable electronic device including a first body, a second body, and a hinge module is provided. The hinge module connects the first body and the second body along a pivoting axis such that the first body and the second body relatively rotate to each other to be folded or unfolded via the hinge module. The hinge module includes a latch disposed in the second body, a shaft member positioned in the latch, a torsion member disposed in the first body to move along with the first body and pivotally connected to the shaft member, and a screw member penetrating through a side surface of the second body from outside the second body and extending inside the second body to lock the latch and the shaft member together. A friction force generated by a relative pivoting of the torsion member and the shaft member forms a torsion force of the hinge module. Part of the screw member is exposed on the side surface of the second body.
