Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking devices for LED display screens are complex, costly, and require large installation spaces, making them difficult to install and increasing the overall thickness of the screen due to their large size and complex structure.
Innovation Solution
A locking device comprising a first lock body with an angle rotating disc and a second lock body with a spring lock, featuring bevels on the angle rotating disc that can adjust the connection angle between LED display screens, allowing for precise arc splicing with improved locating accuracy and reduced splicing difficulty, featuring a compact design that minimizes installation space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If existing locking devices use multiple components to achieve basic strength, then the locking strength is sufficient, but the device complexity increases and the overall size becomes large
Solution Approach 1:
The patent integrates multiple locking components into a single integrated locking body structure. The locking body incorporates the locking head, positioning features, and connecting mechanisms in one unified component, eliminating the need for separate rotary lock heads, fixed heads, and multiple adjusting pieces. This merging maintains the required locking strength while significantly reducing structural complexity and the number of parts.
Solution Approach 2:
The locking body is designed as a multi-functional component that simultaneously provides locking, positioning, and angle adjustment capabilities. The integrated structure performs multiple functions that previously required separate components, including surface-to-surface contact for locking, bevel engagement for positioning, and rotational movement for angle adjustment, all within a single compact unit.
2Reliability
If existing locking devices use multiple components, then the locking function is reliable, but the installation process becomes complicated
Solution Approach 1:
By consolidating multiple locking components into one integrated locking body, the installation process is simplified from assembling multiple separate parts to installing a single pre-integrated unit. The locking body arrives as a complete assembly with all locking, positioning, and adjustment features already combined, reducing installation steps and potential assembly errors while maintaining reliable locking function.
3Adaptability or versatility
If existing locking devices are designed in arc shape to accommodate curved LED screens, then the adaptability improves, but the installation space requirement increases and the overall thickness increases
Solution Approach 1:
The locking body incorporates a rotatable locking head that can dynamically adjust its orientation and position. This rotational capability allows the locking mechanism to adapt to different arc radii and angles without requiring a fixed arc-shaped structure. The locking head can be rotated to match the specific curvature requirements of the LED screen, providing adaptability while maintaining a compact, space-efficient design.
Solution Approach 2:
The locking device uses adjustable parameters including the rotation angle of the locking head and the engagement depth of the bevels to accommodate different arc configurations. By changing these parameters rather than requiring different physical shapes for different arcs, the device achieves versatility while maintaining a consistent compact form factor that minimizes installation space and thickness.
4Volume of stationary object
If existing locking devices position the locking mechanism far from the display surface to accommodate large size, then the internal space is sufficient, but the overall thickness of the LED screen increases
Solution Approach 1:
The locking body is designed with a nested structure where the locking head rotates within the confines of the main body, and the bevels are integrated into the locking head itself. This nesting allows the locking mechanism to achieve its full functional range of motion and locking capacity within a compact envelope, positioning the locking mechanism close to the display surface without requiring excessive internal space or increasing overall screen thickness.
