External Display Module Rotating Screen Gap Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional external display modules experience visual discontinuity due to a gap between the screen unit and the module base during rotation, which interferes with the operation of notebook computers when used in conjunction with an external display.
Innovation Solution
The external display module incorporates a module base with tracks and slots, along with guiding members and blocks, allowing the screen unit to rotate while its edge is moved towards the base side, reducing interference and minimizing the gap between screens, thereby enhancing user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the edge of the screen unit is kept far away from the side of the module base to prevent interference during rotation, then the screen unit can rotate smoothly without interference, but a gap is formed between the screen of the external display module and the screen of the notebook computer causing visual discontinuity
Solution Approach 1:
The patent applies the dynamics principle by implementing a dynamic adjustment mechanism where the screen unit's edge position changes during rotation. The guiding members (curved guides or slots) enable the screen unit edge to move closer to the module base side dynamically during the rotation process, rather than maintaining a fixed distance. This dynamic positioning allows the edge to be far from the base when folded (preventing interference) and close to the base when unfolded (reducing gap and improving visual continuity).
Solution Approach 2:
The patent utilizes dimensional change by introducing a movement path that combines rotation with lateral displacement. Instead of pure rotation around a fixed axis, the screen unit follows a complex trajectory where the guiding members constrain the motion to a path that includes both rotational and translational components. This multi-dimensional movement allows the screen edge to approach the module base during rotation, reducing the visual gap while maintaining rotation functionality.
2Shape
If the screen unit is positioned close to the module base to reduce the gap between screens, then visual continuity is improved, but the screen unit interferes with the module base during rotation
Solution Approach 1:
The patent introduces guiding members (curved guides or slots) as intermediary elements that mediate between the screen unit and the module base. These guiding members constrain and guide the movement of the screen unit during rotation, allowing it to approach the module base without direct interference. The guiding members act as intermediaries that enable close positioning while maintaining smooth rotation by providing a controlled movement path.
Solution Approach 2:
The patent extracts the interference problem by separating the rotation function from the positioning function. Instead of rotating around a fixed axis attached to the module base, the rotation mechanism is extracted and repositioned such that the screen unit rotates while being guided by external guiding members. This extraction allows the screen unit to maintain close proximity to the module base during rotation without the rotating parts directly interfering with the base structure.
3Device complexity
If conventional rotation mechanism is used without guiding members, then the structure is simple, but the screen unit cannot move toward the base side during rotation causing visual discontinuity
Solution Approach 1:
The patent applies parameter changes by modifying the movement parameters of the screen unit during rotation. The guiding members (curved guides or slots) change the trajectory parameters, allowing the screen unit to follow a path where its edge moves closer to the module base side. This parameter change in the movement trajectory enables visual continuity improvement while maintaining relatively simple structure through the use of straightforward guiding elements.
