Adjustable Display Support With Sliding-Rotation Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing supporting apparatuses for drawing boards have fixed installation positions, making it inconvenient for painters to adjust the horizontal and vertical positions, limiting flexibility in painting angles.
Innovation Solution
A supporting apparatus with a bracket and rotating member, allowing sliding and rotational movement within a waist-shaped hole, along with slide rails and rolling members, enables adjustable placement of the drawing board, allowing it to be positioned horizontally, vertically, or at various angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fixed installation positions are used on the bracket, then the structure is simple and stable, but the drawing board cannot be adjusted in horizontal and vertical directions
Solution Approach 1:
The patent applies the dynamics principle by transforming the static fixed installation position into a dynamic adjustable position. The rotating member is introduced to enable the drawing board to rotate and adjust its position dynamically within the waist-shaped hole, while the bracket remains relatively simple in structure. This resolves the contradiction by making the position adjustable without significantly complicating the overall device structure.
2Ease of operation
If the rotating member can slide and rotate freely in the waist-shaped hole, then the drawing board can be positioned at any angle, but the drawing board may not remain stationary without external force
Solution Approach 1:
The patent applies the self-service principle by designing the interaction between the rotating member and the waist-shaped hole such that the rotating member automatically remains stationary at any position it is adjusted to, without requiring external force. The geometric constraint of the waist-shaped hole and the rotating member's shape work together to provide self-locking functionality, allowing the drawing board to maintain its position autonomously.

Function Achieved in This Case
Facilitates convenient adjustment of the drawing board's position, allowing it to be securely stopped at any desired angle, enhancing user experience and usability.
Implementation Method 1
a rolling member 140, the rolling member 140 is connected to the rotating member 120 in a direction perpendicular to an axial direction of the rotating member 120, and is capable of rolling relative to the motion trail surface
Data Source
AI summary
A supporting apparatus and a display device are disclosed. The supporting apparatus is configured for supporting an external apparatus, and includes: a bracket supported on a supporting surface and having a waist-shaped hole; and a rotating member with one end passing through the waist-shaped hole and the other end connected to the external apparatus. Under action of an external force, the rotating member is slidable and rotatable relative to the bracket in the waist-shaped hole. When the external force disappears, the rotating member remains stationary relative to the bracket.
