Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If magnets are used to maintain the folded state, then the stability of the folded state is improved, but magnetic interference with the electromagnetic induction panel increases
Solution Approach 1:
A shielding member is introduced as an intermediary component between the magnets and the electromagnetic induction panel. This shielding member blocks or reduces the magnetic field from reaching the panel, thereby maintaining the folded state stability while preventing magnetic interference with the display functionality.
2Adaptability or versatility
If the flexible display is made bendable to enable folding, then the portability and adaptability are improved, but the durability and protection against moisture ingress deteriorate
Solution Approach 1:
A waterproof member is introduced as a protective film or barrier layer that accompanies the flexible display structure. This waterproof member prevents moisture ingress while maintaining the bendable nature of the display, allowing the device to fold without compromising the display's durability or protection against environmental factors.
3Reliability
If multiple protective layers are added to protect internal components, then the reliability and protection are improved, but the device complexity increases
Solution Approach 1:
The shielding member and waterproof member are integrated into a unified multi-layer protective structure that combines magnetic shielding and moisture protection functions. By merging these protective functions into a coordinated layer system rather than separate independent components, the design achieves comprehensive protection while minimizing overall structural complexity.
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
