Display Pivot Constraint Mechanism for Angle Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional large-scaled displays with heavy weights and large volumes require increased friction in pivot mechanisms, making adjustments inconvenient and prone to shaking or swaying, and existing solutions complicate the operation with lock mechanisms.
Innovation Solution
A display with a constraint mechanism that includes a T-shaped body protruding from the panel, connected to a resilient component, which contacts bridging components to constrain rotation, allowing easy adjustment and steady immovability by unlocking and locking the pivot mechanism without additional steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If friction of the pivot mechanism is increased to support the large-scaled display, then the supporting force is improved, but the ease of operation deteriorates as the user must exert violent force to adjust the display
Solution Approach 1:
The constraint mechanism transitions from a locked state to an unlocked state dynamically, allowing the pivot mechanism to switch between high friction (locked) and low friction (unlocked) conditions. This enables easy adjustment when unlocked while maintaining strong supporting force when locked.
Solution Approach 2:
The constraint mechanism acts as an intermediary between the user and the pivot mechanism. It provides the necessary locking force to support the display weight without requiring the user to directly apply violent force during adjustment operations.
2Reliability
If a lock mechanism is added to constrain the rotation of the pivot mechanism, then the supporting force is improved, but the device complexity increases due to additional releasing and relocking steps
Solution Approach 1:
The constraint mechanism merges the locking and unlocking functions into a single integrated structure that works in conjunction with the pivot mechanism. The contacting portion simultaneously contacts both bridging components, providing constraint without requiring separate lock and unlock operations.
Solution Approach 2:
The constraint mechanism automatically engages and disengages based on the pivot angle. When the display is adjusted to a desired angle, the constraint mechanism self-locks without requiring additional user intervention, and self-unlocks when the display is moved, eliminating the need for manual releasing and relocking steps.
3Stability of the object's composition
If torsional friction is increased to support the large-scaled display, then the stability is improved, but the responsiveness to user input deteriorates causing the display to shake or sway when clicked
Solution Approach 1:
The system dynamically adjusts its friction characteristics through the constraint mechanism. When locked, high friction provides stability; when unlocked, low friction allows responsive movement. This dynamic transition resolves the contradiction between stability and responsiveness.
Solution Approach 2:
The constraint mechanism applies preliminary constraint force to prevent shaking and swaying caused by insufficient supporting force. By preemptively locking the pivot mechanism at the desired angle, it counteracts the harmful effects of increased torsional friction before they can manifest as instability.

Enables convenient and efficient adjustment of the display's view angle with reduced operation steps, providing necessary torque and effective immovability without the need for independent lock and unlock steps, suitable for large-scaled displays.
Implementation Method 1
The constraint mechanism further includes a resilient component. Two ends of the resilient component are respectively connected to the body and the panel
Implementation Method 2
the constraint mechanism further includes a plurality of friction gaskets disposed on the contacting portion for contacting surfaces of the first bridging component and the second bridging component, so as to increase static friction between contacting portion, the first bridging component and the second bridging component

AI summary
A display having pivot constraint function is disclosed in the present invention. The display includes a panel, a supporter, a pivot mechanism and a constraint mechanism. The pivot mechanism is disposed between a first bridging component of the panel and a second bridging component of the supporter. A rotation angle of the panel relative to the supporter can be adjusted via the pivot mechanism, and the constraint mechanism can constrain the rotation of the panel relative to the supporter. The constraint mechanism includes a body and a contacting portion. The body is movably disposed on the panel, and partly protrudes from a boundary of the panel. The contacting portion is connected to the body for simultaneously contacting the first bridging component and the second bridging component, so as to constrain rotation between the first bridging component and the second bridging component, and to fix a view angle of the panel.
