Angled Wall Hanging Slot for Stable Display Panel Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall hanging pieces for display devices, such as electronic picture frames, lack stability due to the ability of the frames to easily slide along stripe-shaped holes when subjected to horizontal forces, leading to poor hanging stability.
Innovation Solution
A wall hanging piece with a plate-shaped hanging portion featuring a stripe-shaped hole where the included angle between the hole's directions is greater than 0 degrees and less than 90 degrees, combined with a fixation portion and connection elements that allow for secure attachment to the wall, ensuring the hanging piece is fixed perpendicular to the gravity direction, thereby preventing lateral sliding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a stripe-shaped hole is used in the wall hanging piece, then the display device can be easily installed, but the display device easily slides along the hole when subjected to horizontal forces, reducing hanging stability
Solution Approach 1:
The patent introduces an asymmetric angle α between the stripe-shaped hole's length direction and the vertical direction. This asymmetric angular configuration creates different friction characteristics in different directions, allowing easy installation while preventing lateral sliding through increased friction resistance in the horizontal direction.
Solution Approach 2:
The patent changes the angular parameter α of the stripe-shaped hole from the conventional vertical alignment (α=0°) to a specific range (5°≤α≤10°). This parameter modification optimizes the balance between installation ease and hanging stability by creating optimal friction conditions that resist lateral forces while maintaining vertical suspension.
2Device complexity
If the wall hanging piece is designed with a simple stripe-shaped hole, then the structure remains simple, but it provides insufficient support against horizontal forces
Solution Approach 1:
The asymmetric angular configuration of the stripe-shaped hole creates directional friction characteristics that provide enhanced resistance to horizontal forces without adding structural complexity. The simple geometric modification of the hole's orientation achieves improved load-bearing capacity while maintaining structural simplicity.
Solution Approach 2:
By modifying the angular parameter α within the optimal range of 5° to 10°, the patent enhances the hole's ability to resist horizontal forces through optimized friction mechanics, achieving improved strength characteristics without increasing device complexity or structural complexity.
3Ease of operation
If the stripe-shaped hole is oriented vertically (perpendicular to wall), then installation is straightforward, but the display device lacks stability against lateral forces
Solution Approach 1:
The patent deviates from the symmetric vertical orientation (α=0°) by introducing an asymmetric angle α between 5° and 10° relative to the vertical direction. This asymmetric orientation creates differential friction resistance that maintains installation straightforwardness while significantly improving anti-sliding reliability through enhanced lateral force resistance.
Solution Approach 2:
The patent optimizes the angular parameter α from the conventional vertical alignment to a specific range (5°≤α≤10°), creating optimal friction conditions that simultaneously maintain ease of installation and provide reliable resistance against lateral sliding forces, thereby improving overall hanging reliability.
