Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a dual-shaft hinge structure is used to enable larger-angle opening and closing, then the opening angle is improved, but the internal structure is exposed during operation, worsening the appearance integrity
Solution Approach 1:
A shielding sheet composed of flexible inner film and outer film is used to cover the hinge module. The films are arranged in layers with the inner film fixed to the hinge module, allowing the shielding sheet to conform to the moving hinge structure while maintaining appearance integrity during opening and closing operations.
Solution Approach 2:
The shielding sheet is designed with movable sections that can dynamically adjust their position and shape during the opening and closing process. The flexible film structure allows the shielding sheet to adapt to the changing geometry of the hinge module, ensuring continuous coverage while accommodating the required motion range.
2Shape
If a shielding sheet is added to cover the hinge module, then the appearance integrity is improved, but the device complexity increases
Solution Approach 1:
Instead of using rigid covering structures or complex mechanical shields, the patent employs flexible film structures that can be easily formed and attached. The inner film and outer film are arranged in layers, creating an effective shielding solution with minimal structural complexity.
Solution Approach 2:
The shielding sheet is constructed as a composite structure with an inner film and an outer film. This composite design allows each layer to serve specific functions (the inner film for structural integration, the outer film for aesthetic appearance) while together providing effective coverage of the hinge module.
3Shape
If the inner film has low ductility and the outer film has high ductility, then the appearance beauty is improved, but the manufacturing precision requirements increase
Solution Approach 1:
Different regions of the shielding sheet have different material properties tailored to their specific functions. The inner film uses low-ductility material for structural stability and precise positioning, while the outer film uses high-ductility material for aesthetic flexibility and visual appeal. This local differentiation of material properties optimizes both appearance and manufacturability.
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 shielding sheet effectively conceals the hinge module, maintaining the device's appearance and smooth operation as it transitions from a closed to an expanded state, enhancing both the integrity and beauty of the foldable electronic device.
Implementation Method 1
the inner film is a film of low ductility, the outer film is a film of high ductility, and the ductility of the inner film is smaller than the ductility of the outer film
