Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices, such as laptops, face challenges in maintaining structural strength and user operation as they become thinner and lighter, particularly when equipped with touch screens, due to reduced torsion in hinges and gaps formed during folding.
Innovation Solution
A hinge module incorporating a guiding rod, an elastic member, and a linking rod mechanism that deforms the elastic member during relative rotation of brackets, providing the necessary torsion and supporting force to maintain the device's state, offering a 'light opening and heavy closing' feel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the device is made thinner and lighter, then the portability is improved, but the structural strength is impaired
Solution Approach 1:
The hinge module employs a dynamic mechanism where the guiding rod moves relative to the first bracket during rotation, transforming the static hinge structure into a dynamic system. This allows the hinge to generate sufficient torsion force through the elastic member deformation while maintaining a compact, lightweight design suitable for thin portable devices.
Solution Approach 2:
The invention changes the physical state and parameters of the elastic member during operation. As the guiding rod moves relative to the first bracket, the elastic member deforms and stores elastic potential energy, then releases it to provide the necessary torsion force. This parameter change enables the lightweight hinge to achieve the required structural strength.
2Length of moving object
If the hinge size is reduced, then the device thickness is decreased, but the torsion is insufficient causing gaps during folding
Solution Approach 1:
The hinge module employs a dynamic mechanism where the guiding rod moves relative to the first bracket during rotation, transforming the static hinge structure into a dynamic system. This allows the hinge to generate sufficient torsion force through the elastic member deformation while maintaining a compact, lightweight design suitable for thin portable devices.
Solution Approach 2:
The guiding rod serves as an intermediary element between the first bracket and the second bracket. It transmits the rotation motion and transforms it into linear movement that deforms the elastic member, which then provides the necessary torsion force to maintain folding stability and prevent gaps.
3Stability of the object's composition
If additional engagement mechanisms are added, then the folding stability is improved, but the device complexity is increased
Solution Approach 1:
The guiding rod performs multiple functions: it guides the rotation motion, transforms rotational movement into linear displacement, and transmits force to deform the elastic member. This multi-functionality eliminates the need for separate engagement mechanisms, maintaining folding stability while avoiding increased complexity.
Solution Approach 2:
The invention merges the functions of guidance, force transmission, and elastic energy storage into a single integrated mechanism. The guiding rod and elastic member work together as a unified system, combining multiple functions that would traditionally require separate components, thus maintaining simplicity while achieving stable folding.
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
The solution ensures sufficient torsion and supporting force are maintained even in thinner and lighter designs, providing a stable and intuitive folding/unfolding experience without impairing the structural integrity or user operation.
Implementation Method 1
the elastic member is deformed while a first bracket and a second bracket rotate relative to each other, and the torsion required by the bodies is provided according to the state of the elastic member

AI summary
A hinge module is provided, including a first bracket, a guiding rod movably assembled to the first bracket, an elastic member connected between the first bracket and the guiding rod, a second bracket pivotally connected to the guiding rod, and a linking rod pivotally connected between the first and the second brackets. In a process of the first and the second brackets rotating relative to each other, the guiding rod moves relative to the first bracket to deform the elastic member. A portable electronic device is also provided.
