Display Module Locking Mechanism for Low-Height Pivot Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display modules risk collision with floors during pivot rotation due to insufficient height adjustment and locking mechanisms, especially when positioned low, which can lead to instability and damage.
Innovation Solution
A display apparatus with a support device that allows pivot rotation and includes a locking mechanism to prevent rotation when the module is at a specific low height, using a locking member that moves into a locking groove to secure the display module in place, preventing floor collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display module is positioned at a low height to save space, then space utilization is improved, but the risk of collision with the floor during pivot rotation increases
Solution Approach 1:
The locking member is positioned in advance to engage with the locking groove before pivot rotation occurs. When the display module is at a low height, the locking member is pre-positioned to automatically engage with the locking groove on the display case, preventing the module from rotating down to collide with the floor. This preliminary locking action eliminates the need for user intervention and ensures safety before the harmful event can occur.
2Reliability
If a locking mechanism is added to prevent collision during pivot rotation, then safety is improved, but device complexity increases
Solution Approach 1:
The locking mechanism operates automatically without requiring user action. The locking member is spring-loaded or gravity-assisted to automatically engage with the locking groove when the display module is positioned at a low height, and automatically disengage when the module is raised. This self-service operation eliminates the need for motors, sensors, or control systems, maintaining structural simplicity while ensuring safety.
Solution Approach 2:
The locking function is extracted as a separate, simple mechanical component (locking member and locking groove) independent from the main support arm mechanism. This modular approach allows the locking feature to be added without complicating the primary height adjustment and pivot rotation mechanisms, keeping the overall device complexity low.
3Object-affected harmful factors
If the locking member is always engaged to prevent rotation, then collision prevention is improved, but ease of operation deteriorates
Solution Approach 1:
The locking mechanism transitions from a static always-engaged state to a dynamic conditional state. The locking member is designed to automatically engage only when the display module is at a low height (where collision risk exists) and automatically disengage when the module is raised above a certain height. This dynamic behavior provides collision prevention exactly when needed while maintaining full rotational freedom during normal operation, thus preserving ease of use.
Solution Approach 2:
The locking member applies a preliminary restraining force only when the display module is in the dangerous low-position range. When the module is properly positioned at a higher height, the locking member is designed to automatically retract or disengage, eliminating any restraining force and allowing free pivot rotation. This conditional anti-action prevents harm only when necessary without interfering with normal operation.

AI summary
A display apparatus includes: a display module including a display panel and a display case supporting the display panel and including a locking portion; and a support device supporting a rear of the display module and configured to enable pivot rotation of the display module, wherein the support device includes: a support arm configured to be rotatably coupled to a support object and enable the display module to move between a first position and a second position at a lower height than the first position, and a locking member inserted into the locking portion and configured to lock the pivot rotation of the display module when the display module is in the second position.
