Sliding Mechanism Supporting Device for Multi-Angle Tablet Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable electronic devices, such as tablet computers, often lack adjustable angles, leading to instability when used in environments without a desk, as the weight of the screen can cause the device to fall backward, failing to accommodate diverse user environments and operating habits.
Innovation Solution
A supporting device with a sliding mechanism between a back cover and a bracket, allowing for the formation of three adjustable angles by using a guiding slot, sliding portion, and stopper, enabling users to adjust the device to suit their needs and maintain stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a tablet computer is integrated with a docking station with only two unfolding angles, then the structure is simple, but it cannot meet the requirements of all users in different environments and conditions
Solution Approach 1:
The patent applies the dynamics principle by implementing a sliding mechanism that allows the back cover to move dynamically between multiple fixed positions (first end, second end, and intermediate position with stopper). This enables three distinct unfolding angles (first, second, and third angles) to be achieved, transforming a static two-angle structure into a dynamic multi-angle system that adapts to different usage scenarios while maintaining structural integrity
Solution Approach 2:
The guiding slot is segmented into distinct regions with the stopper creating an intermediate positioning point. This segmentation divides the continuous sliding path into three discrete stable positions, allowing the device to offer multiple fixed angles rather than continuous adjustment, thus balancing adaptability with structural simplicity
2Ease of operation
If a notebook computer is placed on legs without a desk, then portability is improved, but the weight of the screen end causes the device to be unstable and fall backward
Solution Approach 1:
The supporting device acts as a counterweight mechanism that offsets the weight of the screen end. By providing an extended bracket structure with adjustable angles, it creates a balancing support that prevents the device from falling backward when placed on legs, effectively counteracting the destabilizing effect of the screen weight while maintaining portability
3Adaptability or versatility
If conventional devices provide only two unfolding angles, then manufacturing is simpler, but they cannot provide excellent convenience in different environments and conditions
Solution Approach 1:
The patent implements a dynamic sliding mechanism within the back cover assembly that enables three distinct unfolding angles. This dynamic structure allows the device to adapt to various environmental conditions and usage scenarios (e.g., on legs, on desk, different viewing angles) while maintaining a relatively compact and manufacturable design through the use of guiding slots and stoppers rather than complex articulated mechanisms

AI summary
A supporting device includes a first bracket, a back cover, and a sliding mechanism. The sliding mechanism is located between the back cover and the first bracket. The sliding mechanism includes a guiding portion, a sliding portion, and a stopper. The guiding portion is disposed at the first bracket and has a guiding slot, where the guiding slot has a first end and a second end opposite to each other. The sliding portion is disposed at the back cover, and adapted to slide in the guiding slot along a sliding direction. The stopper is located between the first end and the second end of the guiding slot and is adapted to move out of the guiding slot in a moving direction perpendicular to the sliding direction.
