Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a torque module is added to generate enough torque, then the supporting effect is improved, but the overall size is enlarged
Solution Approach 1:
The patent merges the torque generation function with the hinge structure itself. The tabs are integrated into the hinge module, and their elastic deformation provides the necessary torque without requiring a separate torque module. This combination eliminates the need for additional components that would increase the overall size.
Solution Approach 2:
The hinge module generates its own torque through the elastic deformation of the tabs. The tabs act as elastic elements that automatically provide the required torque during the opening and closing operations, eliminating the need for external torque-generating components.
2Adaptability or versatility
If a torque module is added to generate adjustable torque, then the torque adjustment capability is improved, but the structural complexity increases
Solution Approach 1:
The patent achieves torque adjustment by changing the physical parameters of the tabs, specifically their thickness. By providing tabs with different thicknesses, the hinge module can offer different torque characteristics. This simple parameter change approach avoids complex adjustment mechanisms while maintaining adaptability.
Solution Approach 2:
The hinge module incorporates a dynamic adjustment mechanism where the torque adjustment member can move between different positions (first position and second position) to change the torque characteristics. This allows the system to adapt to different operational requirements without significant structural complexity.
3Force
If accommodating space is preset for the torque module, then the torque generation function is improved, but the overall design is enlarged
Solution Approach 1:
The torque generation function is merged into the existing hinge structure. The tabs are formed as integral parts of the hinge module, eliminating the need for separate accommodating spaces for torque modules. The hinge module itself serves as both the structural connection and the torque-generating element.
4Force
If a valve is used to generate a second torque, then the torque generation is improved, but the torque adjustability is lost
Solution Approach 1:
The patent replaces the fixed-torque valve mechanism with tabs of varying thicknesses. By selecting tabs with different thickness parameters, the system can adjust the torque characteristics to suit different operational requirements, providing adaptability that the conventional valve mechanism lacks.
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
Enables adjustable torque and convenient lifting/lowering of buttons, maintaining a compact design while allowing users to set desired angles, without the need for additional mechanical or electronic activation mechanisms.
Implementation Method 1
The torque adjustment member inserts into the corresponding first through holes of the brackets and the corresponding second sliding slots of the tabs
Implementation Method 2
with the lock of the torque adjustment member, the torque of the tabs relative to the brackets may be easily adjusted
Implementation Method 3
In the moving process of the hinge module, the tabs move on a linear direction
Implementation Method 4
the sliding rod connected correspondingly between the tabs and the sliding sheet moves along with the tabs and the buttons are thus lifted and lowered during the moving process

AI summary
A hinge module and an electronic device are provided. The hinge module includes a pair of brackets, a plurality of tabs, a torque providing assembly, and a torque adjustment member. Each bracket has at least one first sliding slot extending along a first direction and a first through hole extending along a second direction, wherein the first direction and the second direction are perpendicular to each other. The tabs pass through the corresponding ones of the first sliding slots, and the tabs have second sliding slots extending along the second direction. The torque providing assembly has a first end connected to one of the brackets and one of the tabs and a second end connected to the other one of the brackets and the other one of the tabs. The torque adjusting member inserts into the first through holes of the brackets and the second sliding slots of the tabs.
