Display Unit Locking Structure for Flat Splicing Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ensuring the flatness of the display surface of flexibly detachable display units in display devices is crucial for improving display performance, but existing technologies lack effective mechanisms to maintain this flatness during installation and use.
Innovation Solution
A locking device comprising a bracket and a support plate with pins and switches that lock into place, resisting movement to maintain the flatness of the display surface, allowing for splicing of multiple display units by adjusting pin heights to fit a common platform.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If display units are made flexibly detachable to meet various display requirements, then adaptability is improved, but maintaining the flatness of the display surface becomes difficult
Solution Approach 1:
The locking device is segmented into multiple independent components: a bracket, a support plate, a first pin assembly, and a second pin assembly. Each component performs a specific function - the first pin assembly maintains the minimum distance to ensure flatness, while the second pin assembly prevents excessive insertion. This segmentation allows the system to be detachable yet maintain precise positioning when assembled.
Solution Approach 2:
The locking device utilizes parameter changes through the elastic component in the first pin assembly. The elastic component allows the first pin to change its position parameter dynamically - it can be compressed during assembly and then maintains a fixed position when locked, enabling the transition from a flexible assembly process to a rigid fixed state that ensures flatness.
2Manufacturing precision
If a locking mechanism is added to maintain flatness, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The locking device merges multiple functions into a compact structure. The bracket and support plate are connected through both pin assemblies simultaneously, combining the functions of positioning, locking, and spacing maintenance in a single integrated mechanism. This merging reduces the number of separate components needed compared to using independent locking mechanisms for each function.
Solution Approach 2:
The first pin assembly incorporates an elastic component that provides automatic resetting functionality. When the first pin is compressed during assembly, the elastic component stores energy and automatically pushes the pin back to its original position after locking, eliminating the need for additional mechanisms to reset the positioning element. This self-service feature simplifies the overall device structure.

AI summary
A locking device includes a bracket and a support plate arranged opposite to each other, a side of the support plate facing away from the bracket being used for carrying a display unit. One of the bracket and the support plate includes a first pin, and the other one of the bracket and the support plate includes a first switch. When the first switch is in a locked state, the first pin is inserted into the first switch, and the first switch resists the first pin from being pulled out. One of the bracket and the support plate includes a second pin, and the other one of the bracket and the support plate includes a second switch. When the second switch is in the locked state, the second pin is inserted into the second switch, and the second switch resists further insertion of the second pin.
