Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices with adjustable displays often lack a seamless and effortless adjustment mechanism, resulting in a cumbersome user experience due to inadequate counter-balancing of the display's weight, leading to torque issues and limited mobility.
Innovation Solution
The implementation of a hinge system with multiple biasing elements, including springs and crankshafts, that counter-balance the display's weight, allowing for effortless rotation and adjustment of the display's angle while maintaining a compact footprint, by translating the arm assembly's angle into specific display orientations through a non-linear motion path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hinge system with multiple biasing elements is implemented to counter-balance the display's weight, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent implements a hinge system with multiple biasing elements (springs) that counter-balance the display's weight. The first spring counter-balances the display at a first set of display angles, while the second spring counter-balances the display at a second set of display angles. This anti-weight mechanism allows the display to be adjusted effortlessly across different positions without requiring excessive force from the user.
Solution Approach 2:
The patent divides the counter-balancing function into multiple independent springs, each responsible for specific angular ranges. The first spring operates effectively at certain display angles while the second spring operates at other angles. This segmentation allows each spring to be optimized for its specific range, reducing the overall complexity compared to a single spring trying to handle all angles.
2Force
If springs are used to counter-balance the display weight, then the force required for rotation is reduced, but the device size increases
Solution Approach 1:
The biasing elements (springs) are configured to counter-balance the weight of the display at different angles. The first spring counter-balances the display when it is at the first set of display angles, and the second spring counter-balances the display when it is at the second set of display angles. This reduces the force required for rotation throughout the full range of motion.
Solution Approach 2:
The patent employs a dynamic counter-balancing system where the effectiveness of each spring varies with the display angle. The first spring is more effective at certain angles while the second spring takes over at other angles, creating a continuously adaptive force distribution that minimizes the required device volume while maintaining low rotation force across all positions.
3Adaptability or versatility
If the hinge system translates arm assembly angle to specific display orientations through non-linear motion path, then the adaptability is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The hinge system implements a non-linear motion path that dynamically translates arm assembly angles to specific display orientations. The relationship between arm angle and display orientation is not linear, allowing for greater adaptability and versatility in achieving various display positions. The dual-spring configuration helps manage the complexity of this non-linear relationship.
Solution Approach 2:
The patent changes the motion parameters from a simple linear relationship to a non-linear motion path. This allows the display to achieve a wider range of orientations and positions for the same arm assembly rotation, improving adaptability. The parameter change is managed through the combined effect of multiple springs with different characteristics.
