Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a flexible foldable screen is used to achieve a large portable display area, then the device can be compact when folded and large when unfolded, but wrinkles appear on the screen surface in the flat state which affects appearance and product life
Solution Approach 1:
The patent introduces a dynamic support mechanism with sliding members and rotating shafts that adapt to the flexible display panel during state transitions. The support component moves from a first position (folded state) to a second position (flat state) through sliding and rotating motions, dynamically adjusting to maintain screen flatness while preserving the flexibility needed for folding and unfolding operations
Solution Approach 2:
The support component acts as an intermediary between the flexible display panel and the device housing. This intermediary mechanism includes sliding members that move along guide rails and rotating shafts that facilitate controlled motion, mediating the transition between folded and flat states while preventing direct contact that would cause wrinkles on the display surface
2Adaptability or versatility
If the flexible display panel is allowed to bend freely for folding and unfolding, then the device achieves portability and structural diversity, but the bending motion causes wrinkles and reduces service life
Solution Approach 1:
The support mechanism employs dynamic sliding and rotating components that adapt during state transitions. The sliding members move along guide rails while rotating shafts enable controlled angular motion, creating a dynamic system that preserves folding capability while preventing harmful wrinkle formation through coordinated motion control
Solution Approach 2:
The support component provides beforehand cushioning by positioning itself to support the flexible display panel before complete flattening occurs. The sliding members and rotating shafts are designed to engage and provide support during the transition process, cushioning against abrupt movements that would cause wrinkles and extend service life
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 prevents wrinkles in the flat state, enhancing the appearance and service life of foldable display devices by allowing for proper bending and stretching of the flexible panel.
Implementation Method 1
at least one driving component including a first magnetic member and a second magnetic member, wherein a magnetic force between the first magnetic member and the second magnetic member provides a driving force for the first sliding member to move along a direction away from the at least one rotating shaft
