Solution Overview
Problem
Conventional display apparatuses are limited in providing various viewing modes as they typically output images in a fixed landscape mode, lacking the ability to easily switch between landscape and portrait orientations.
Innovation Solution
A display apparatus featuring a linearly-movable assembly with a connector assembly and guide mechanism that allows the display module to rotate between landscape and portrait modes, with automatic vertical adjustment, facilitated by a driver assembly, gears, and elastic members for smooth movement and secure locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display module is fixed in landscape mode, then the structure is simple and stable, but the viewing modes are limited
Solution Approach 1:
The display module is transformed from a fixed static structure to a dynamic one that can rotate between landscape and portrait modes. The rotation assembly enables the display module to change its orientation dynamically, providing multiple viewing modes while maintaining a relatively simple overall structure through standardized mechanical components.
2Ease of operation
If the display module is rotated manually, then the structure is simple, but the operation is inconvenient and time-consuming
Solution Approach 1:
The manual mechanical rotation operation is replaced with an automated driving mechanism. The driving assembly uses a motor to automatically rotate the display module between landscape and portrait modes, eliminating the need for manual operation while keeping the rotation mechanism relatively simple through direct motor-driven rotation.
3Ease of operation
If the display module is rotated without vertical adjustment, then the structure is simple, but the viewing comfort is poor
Solution Approach 1:
The rotation function and vertical adjustment function are merged into a single integrated assembly. When the display module rotates between landscape and portrait modes, the supporting structure automatically adjusts the vertical position to maintain optimal viewing height, providing viewing comfort without requiring separate adjustment mechanisms.
4Reliability
If heavy components are used for stable rotation, then the rotation is stable, but the overall weight increases
Solution Approach 1:
The rotation mechanism uses friction-based friction pads and friction wheels instead of heavy mechanical gears or belts. By optimizing the friction parameters and contact surfaces, the system achieves stable rotation and positioning without requiring heavy components, thereby maintaining low overall weight while ensuring rotation reliability.
