Rotatable Module Torsion Hinge Mechanism for One-Handed Keypad Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sliding-type electronic devices are cumbersome and not user-friendly, requiring users to manually push and hold them to expose keypad modules, which complicates operation, especially in critical situations.
Innovation Solution
An electronic device featuring a first module, a second module, a control module, and a torsion hinge, where the second module is rotatably disposed between two positions and the control module is slidably positioned between third and fourth positions, allowing the second module to be automatically rotated 180 degrees by the torsion hinge when the control module is actuated, thereby exposing the keypad.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electronic device uses a conventional sliding-type mechanism, then the keypad module can be exposed, but the device becomes cumbersome and requires two hands to operate
Solution Approach 1:
The patent applies the dynamics principle by implementing a rotatable second module that can automatically rotate between a first position (covering the keypad) and a second position (exposing the keypad) through a torsion hinge mechanism. This dynamic rotation eliminates the need for manual sliding operations, allowing one-handed operation while maintaining the keypad exposure function.
Solution Approach 2:
The patent applies the self-service principle through the torsion hinge mechanism that automatically rotates the second module when the control module is actuated. The system performs the module rotation automatically without requiring the user to manually push or hold the device, enabling convenient one-handed operation.
2Productivity
If the electronic device requires manual pushing to expose the keypad, then the mechanism is simple, but operation becomes complicated in critical circumstances
Solution Approach 1:
The patent applies the preliminary action principle by positioning the control module to directly actuate the torsion hinge mechanism. When the control module is actuated, it immediately triggers the automatic rotation of the second module, eliminating intermediate manual pushing steps and enabling rapid one-handed operation in critical circumstances.
3Ease of operation
If the second module is fixed in position, then the structure is stable, but the keypad cannot be exposed for viewing
Solution Approach 1:
The patent applies the dynamics principle by implementing a rotatable second module connected through a torsion hinge, allowing the module to dynamically transition between a first position (stable, covering keypad) and a second position (exposing keypad). This maintains structural stability when closed while enabling keypad accessibility when needed.
Solution Approach 2:
The patent applies the parameter changes principle by changing the angular position parameter of the second module between two discrete states: covered position (first position) and exposed position (second position). This allows the module to maintain stability in each state while enabling transition for keypad accessibility.

AI summary
An electronic device is provided, including a first module (11,21), a second module (12,22), a control module (13,23), and a torsion hinge (14,24). The second module (12,22) is rotatably disposed on the first module (11,21) between a first position (I) and a second position (II). The control module (13,23) is slidably disposed on the first module (11,21) between a third position (III) and a fourth position (IV). When the control module (13,23) is in the third position (III), the second module (12,22) is restricted to rotate with respect to the first module (11,21). When the control module (13,23) is in the fourth position (IV), the second module (12,22) is released by the control module (13,23) and rotatable with respect to the first module (11,21).
