Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a pair of magnetic elements are used to maintain the folded state through mutual attractive force, then the folded state stability is improved, but the user experience deteriorates due to sharp increase in attractive force causing hand grip
Solution Approach 1:
The magnetic module is designed to move relative to the display panel, transitioning between a first position (during folding) and a second position (in folded state). This dynamic positioning allows the magnetic attraction force to be modulated: when the module is in the first position, the attraction force is limited to prevent hand grip; when in the second position, the attraction force is maximized to ensure folded state stability.
Solution Approach 2:
The magnetic maintenance function is segmented into two distinct operational phases: (1) during the folding process where the magnetic module is positioned to provide limited attraction, and (2) in the folded state where the magnetic module is positioned to provide maximum attraction. This segmentation allows different magnetic force levels to be applied at different stages, resolving the contradiction between ease of operation and stability.
2Stability of the object's composition
If the distance between magnetic elements is shortened to increase attractive force, then the folded state stability is improved, but the harmful effect increases due to excessive attractive force gripping user hands
Solution Approach 1:
The distance between magnetic elements is dynamically adjusted through the magnetic module's movement. During folding, the module is positioned at a distance that limits attractive force to below harmful levels. In the folded state, the module moves to a position that maximizes attraction force for stability, thus eliminating the harmful effect while maintaining the benefit.
Solution Approach 2:
The magnetic module is preliminarily positioned in a first position during the folding process that prevents excessive attractive force from acting on the user's hands. This preliminary positioning ensures that when the user completes the folding action, the magnetic force does not interfere with the operation. After folding is complete, the module then moves to the second position to provide maximum stability.
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 effectively reduces initial user discomfort by minimizing the initial attractive force and ensures a stable folded state by gradually increasing the attractive force to its maximum value, enhancing user experience and device stability.

AI summary
Provided display device includes at least one magnetic component, first display segment and second display segment connected to each other and foldable towards each other. The magnetic component includes first magnetic module located in non-display region of first display segment and second magnetic module located in non-display region of second display segment. The display device includes first folded state in which contact ends come into contact and second folded state in which the contact ends in contact for period of time. The attractive force A of the first magnetic module to the second magnetic module in the first folded state is smaller than the attractive force B thereof in the second folded state. The preceding solution can prevent the user's hands from being gripped when the user folds the display device and can ensure that the display device maintains stable folded state.
