Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional pushing-down operations and hooking constructions are used for locking mechanisms, then the structure is simple, but the relative movement between bodies is limited and form factor versatility is restricted
Solution Approach 1:
The patent replaces traditional mechanical pushing-down operations and hooking constructions with a magnetic field-based locking mechanism. The magnet assembly generates magnetic attraction forces to lock the second body at specific angles relative to the first body, eliminating the need for complex mechanical hooks and pushing-down operations while enabling versatile relative movement and adjustable form factors
Solution Approach 2:
The patent changes the locking mechanism from fixed mechanical engagement to adjustable magnetic field-based engagement. By controlling the magnetic attraction force and positioning the magnet assembly at different locations, the system achieves multiple locking positions and angles, transforming a single-state mechanical lock into a multi-state adjustable locking system
2Adaptability or versatility
If magnet and metallic member are used for fixing, then the locking mechanism becomes more versatile with adjustable angles, but the device complexity increases
Solution Approach 1:
The magnet assembly serves multiple functions: it provides locking force through magnetic attraction, enables angle adjustment by repositioning along the rotation axis, and can be controlled to lock or unlock positions. This single component replaces what would traditionally require separate locking mechanisms, positioning systems, and control elements, achieving multi-functionality that reduces overall system complexity despite the advanced physics involved

Function Achieved in This Case
The solution enhances the versatility of relative movement and locking mechanisms, enabling more flexible form factors and user interfaces, improving usability and functionality by allowing adjustable angles and smooth transitions between different operational modes.
Implementation Method 1
a magnet that is provided to one of the second body and the second frame, and a metallic member that is provided to the other of the second body and the second frame, and that is formed in such a manner that a magnetic force of the magnet is exerted to the metallic member
Implementation Method 2
an elastic member that exerts an elastic force to the manipulating member in order that the moving member, moved by the pushing-down operation of the manipulating member, returns to its previous position

AI summary
A portable terminal having a first body, a second body and a hinge module connecting the second body to the first body such that the second body is movable relative to the first body is provided. The hinge module includes a first frame rotatably connected to the first body and a second frame connected to the first frame to support at least one portion of the second body in a supporting state, the second frame being connected to the second body such that the second frame is rotatable relative to the second body in order to allow the second body to rotate in the supporting state.
