Detachable Flip Cover Hinge for Over-Torque Damage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flip cover devices are prone to damage or breakage due to excessive stress from improper and excessive pivotal movements, as the cover can interfere with the main body and suffer permanent structural damage when forced to unfold.
Innovation Solution
A flip cover device with a hinge featuring a notch structure that allows the cover to disengage from the hinge via a reaction force when excessive torque is applied, preventing damage by enabling detachment and easy reconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cover is pivotally connected to the main body with a fixed hinge structure, then the cover can maintain stable positioning at predetermined angles, but the cover is prone to permanent structural damage when excessive torque is applied
Solution Approach 1:
The hinge structure transitions from a fixed rigid connection to a dynamic detachable connection. The pivotal structure can automatically disengage from the hinge body when excessive torque is applied, allowing the connection state to change based on operational conditions. This resolves the contradiction by providing both stable positioning during normal use and damage prevention under excessive stress.
Solution Approach 2:
The pivotal structure acts as an intermediary element between the cover and the hinge body. It can selectively engage or disengage from the hinge body, mediating the force transmission. When normal torque is applied, it maintains stable connection for positioning; when excessive torque is applied, it disengages to protect the cover structure.
2Strength
If the cover is forced to unfold beyond its design limits, then the cover may be driven to disengage from the hinge to prevent damage, but this requires a complex detachable hinge structure
Solution Approach 1:
The hinge structure is designed to automatically detect and respond to excessive torque conditions without external intervention. The pivotal structure self-activates to disengage when the reaction force from the abutting portion exceeds the holding force, and can self-reengage when normal conditions are restored. This simplifies the overall system by eliminating the need for external sensors or control mechanisms.
Solution Approach 2:
The hinge structure utilizes changes in force parameters to control the engagement and disengagement states. The pivotal structure transitions between engaged and disengaged states based on the magnitude of applied torque, with the transition point determined by the geometric parameters of the abutting portion and the pivotal structure's positioning within the hinge body.
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
Prevents permanent structural damage to the cover by allowing disengagement from the hinge under excessive stress, facilitating easy recovery and maintenance while maintaining pivotal functionality.
Implementation Method 1
a resilient abutting portion is formed on an end portion of the at least one pivotal structure. The resilient abutting portion is resiliently deformed during a process that the at least one pivotal structure pivotally passes through the pivoting portion of the hinge body, and the resilient abutting portion resiliently recovers to abut against the pivoting portion after the at least one pivotal structure pivotally passes through the pivoting portion of the hinge body.

AI summary
A flip cover device is provided and includes a cover, a main body and a hinge. The hinge is disposed on the main body and pivotally connected to the cover in a detachable manner for allowing the cover to pivotally unfold relative to the main body. The hinge includes a hinge body and a notch structure formed on the hinge body. The cover abuts against the main body when the cover pivotally unfolds relative to the main body to an unfolded position along a first pivoting direction. When the cover is located at the unfolded position and forced by a torque along the first pivoting direction, the cover is driven by a reaction force provided by the main body to disengage from the hinge, which prevents a damage of the cover caused by an improper and excessive pivotal movement of the cover. Besides, a related hinge is further provided.
