Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a hinge structure is used to enable folding, then the device achieves lightness and thinness, but the hinge structure is exposed to air and cannot prevent foreign matter and dust from entering
Solution Approach 1:
A dustproof membrane is introduced to cover the hinge structure, forming a flexible sealing film that prevents dust and foreign matter from entering while allowing the hinge to fold. The membrane is configured to deform with the hinge's movement, maintaining sealing effectiveness throughout the folding range.
Solution Approach 2:
The dustproof membrane is designed to dynamically deform along with the hinge structure during folding and unfolding. The elastic member enables the membrane to adapt its shape to the hinge's changing configuration, ensuring continuous dustproof protection without restricting the folding motion.
2Object-affected harmful factors
If a dustproof membrane is added to seal the hinge structure, then dust and foreign matter are prevented from entering, but the membrane may separate or expose during folding
Solution Approach 1:
An elastic member is introduced as an intermediary component between the dustproof membrane and the hinge structure. This elastic member securely connects the membrane to the hinge, preventing separation during folding while allowing the membrane to deform with the hinge's motion, thus maintaining continuous sealing.
Solution Approach 2:
The elastic member is pre-configured to engage with the hinge structure before folding occurs. This preliminary connection ensures that the dustproof membrane is securely attached and will not separate during the folding process, maintaining sealing integrity from the start of the folding motion.
3Reliability
If the dustproof membrane is rigidly fixed to prevent separation, then sealing is maintained, but stress is transmitted to the flexible screen during folding
Solution Approach 1:
The dustproof membrane is designed as a flexible film that can deform during folding. This flexibility allows the membrane to maintain sealing contact with the hinge structure while accommodating the motion without transmitting excessive stress to the flexible screen, thus protecting the screen from damage.
Solution Approach 2:
The elastic member is designed with specific elastic properties that allow it to deform under stress. When the hinge folds, the elastic member absorbs and distributes the mechanical stress, preventing concentrated forces from being transmitted to the flexible screen while maintaining the dustproof seal.
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 dustproof assembly effectively seals the hinge structure throughout the folding process, protecting the device from dust and foreign matter, while adapting to the flexible screen's deformation without causing stress, thus ensuring reliable operation and user safety.
Implementation Method 1
an elastic member connected to the bracket through the first convex portion, wherein the elastic member has a first state and a second state, when the elastic member is in the first state, the elastic member is unfolded, and when the elastic member is in the second state, two ends of the elastic member are relatively folded around the first protrusion

AI summary
A dustproof assembly and a foldable electronic device are provided. The dustproof assembly includes a bracket and an elastic member connected with the bracket. The elastic member has a first and a second state. When the elastic member is in the first state, the elastic member is unfolded. When the elastic member is in the second state, the elastic element is relatively folded around a first convex portion. The dustproof assembly also includes a dustproof membrane. One end of the dustproof membrane is fixed on a second convex portion, and another end of the dustproof membrane is fixed on the elastic member. The elastic member drives the dustproof membrane to deform and switch between the first state and the second state.
