Movable Display Fulcrum Switching Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional movable display devices that tilt in both forward and backward directions require additional space in the chassis for the display body's lower end to retract and accommodate separate driving mechanisms, leading to space constraints.
Innovation Solution
A movable display device with a fulcrum switching mechanism that allows the display body to switch between two pivoting states, enabling tilting in both upward and downward directions without narrowing the chassis space, using an upper and lower pivoting part engageable with corresponding bearing parts and a sliding member linked to an intermediate point between these parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display body is tilted to forward tilted orientation with the lower end retracting, then the display can be viewed from below, but the chassis space is narrowed due to the retraction space requirement
Solution Approach 1:
The patent applies dynamics by making the pivoting point of the display body switchable between upper and lower positions. This allows the system to adapt its mechanical configuration dynamically: when the lower pivoting point is selected, the display body tilts forward with the upper end retracting instead of the lower end, thereby avoiding the space consumption problem while maintaining forward tilting capability
Solution Approach 2:
The patent inverts the traditional tilting mechanism by switching which end of the display body pivots. Instead of the lower end pivoting forward (which requires retraction space), the upper end pivots forward, causing the upper end to retract instead. This inversion of the pivoting point eliminates the chassis space problem while achieving the same functional goal of forward tilting
2Adaptability or versatility
If separate driving mechanisms are provided for upper and lower sliding members, then dual-directional tilting is achieved, but the device complexity increases
Solution Approach 1:
The patent applies universality by designing a single driving mechanism that can control both the upper and lower sliding members. This single mechanism performs multiple functions: it can advance or retract either sliding member independently, and can also coordinate their movements. This multi-functionality reduces the number of separate driving mechanisms from two to one, thereby reducing device complexity while maintaining dual-directional tilting capability
Solution Approach 2:
The patent merges the control of upper and lower sliding members into a single driving mechanism. Instead of having separate motors or actuators for each sliding member, one driving mechanism is designed to control both, consolidating the driving functions and reducing overall system complexity while achieving the same operational versatility

AI summary
An upper guide and a lower guide are provided on an escutcheon integrally attached to the chassis. An upper movable pin engageable with and disengageable from the upper guide, a lower movable pin engageable with and disengageable from the lower guide, and a fulcrum switching mechanism that reciprocates the upper movable pin and lower movable pin in the left-right direction are attached to a display body disposed in front of the escutcheon. The fulcrum switching mechanism makes the rotational fulcrum of the display body switchable between a first pivoting state, in which the upper movable pin is engaged with the upper guide and the lower movable pin is disengaged from the lower guide, and a second pivoting state, in which the lower movable pin is engaged with the lower guide and the upper movable pin is disengaged from the upper guide.
