Display Device Tilting Mechanism Friction Holding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices with tilting display bodies require stronger holding power to maintain the display body at an optional position, which can be burdensome for users, especially when the display body is heavier, as it necessitates a stronger load to initiate movement.
Innovation Solution
A display device equipped with a supporting mechanism, a pressing mechanism using elastic members to store and apply repulsive force, and a position holding mechanism with contact members to generate friction, allowing the display body to be held at any position between vertical and inclined positions with reduced holding force requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the holding power for holding the display body is strengthened, then the display body can be held stably at an optional position, but a stronger load is required to start the movement of the display body
Solution Approach 1:
The holding mechanism is divided into two independent contact members (first contact member and second contact member) that can be pressed against each other to generate friction force. This segmentation allows the holding function to be achieved through distributed friction rather than a single strong holding point, reducing the load required to initiate movement while maintaining holding stability.
Solution Approach 2:
The conventional mechanical holding system that relies on strong direct mechanical engagement is replaced with a friction-based holding system. The first and second contact members generate holding force through contact friction, which provides stable holding with lower activation force compared to traditional mechanical locking mechanisms.
2Area of moving object
If the display body is made heavier, then the display surface can be larger to display more information, but stronger holding power is required
Solution Approach 1:
The elastic member is pre-compressed between the display body and the first contact member to generate preliminary repulsive force. This preliminary action creates continuous contact pressure that generates friction force, enabling the heavier display body to be held stably without requiring additional strong holding mechanisms.
Solution Approach 2:
The weight support function is partially replaced by the friction force generated through the contact mechanism. Instead of relying solely on strong mechanical holding power to counteract the weight of a larger display body, the system uses friction between contact members to provide holding force, reducing the burden on the overall holding mechanism.
3Reliability
If the elastic member is compressed more to increase repulsive force, then the display body can be held more securely, but the load required to compress it further increases
Solution Approach 1:
The elastic member is compressed to a degree that generates sufficient repulsive force for stable holding, but not to excessive levels. The contact friction mechanism between the first and second contact members provides the necessary holding security without requiring excessive compression of the elastic member, thus avoiding unnecessarily high forces.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the display body to be moved by a relatively small load, reducing the burden on users while maintaining stability and positional control, even with heavier display bodies, by utilizing the repulsive force and friction generated by the elastic members and contact mechanisms.
Implementation Method 1
a pressing mechanism having an elastic member for storing repulsive force by being pressed by the display body as the display body moves from the vertical position to the inclined position, and for pressing the display body by the repulsive force of the elastic member
Implementation Method 2
a position holding mechanism having a first contact member for contacting the display body and a second contact member for pressing the first contact member in an axis direction of the supporting axis, and for holding the display body at an optional position between the vertical position and the inclined position by contact friction generated between the first contact member and the second contact member

AI summary
A supporting mechanism movably supports a display body, a display surface of which is in the vertical position and in an inclined position. A pressing mechanism has an elastic member which stores repulsive force by being pressed by the display body as the display body moves from the vertical position to the inclined position, and presses the display body by the repulsive force in the direction from the inclined position to the vertical position. A position holding mechanism holds the display body at an optional position anywhere between the vertical position and the inclined position.
