Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking devices for LED display screens are complex, costly, and require large installation spaces due to their large size and complex structure, making them difficult to install and reducing the accuracy of arc splicing.
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 of varying angles that allow for adjustable connection angles between LED display screens, simplifying the structure and facilitating precise splicing with reduced installation space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the locking device uses a complex structure with multiple components to achieve basic strength, then the strength is sufficient, but the device complexity increases and cost rises
Solution Approach 1:
The patent combines multiple components into an integrated locking mechanism where the lock body, locking pin, and positioning features are merged into a single unified structure. This integration maintains the required basic strength while eliminating the complexity of assembling and coordinating multiple separate components, directly resolving the contradiction between strength and structural complexity.
Solution Approach 2:
The locking device is designed with universal features that allow it to perform multiple functions: securing LED screens, enabling arc splicing, and providing adjustable connection angles. By incorporating these multi-functional capabilities into a single device structure, the patent achieves basic strength requirements without adding unnecessary complexity, as the same structure serves multiple purposes.
2Strength
If the locking device is made large in size to accommodate necessary components, then the components can reach basic strength, but the installation space requirement increases
Solution Approach 1:
The patent employs a nested design where the locking pin and positioning features are integrated within the lock body structure itself. This nesting allows the components to achieve basic strength through their integrated configuration rather than requiring separate, space-consuming elements, thereby reducing the overall installation space while maintaining structural integrity.
3Ease of operation
If the locking device is positioned far from the display surface to accommodate its size, then the structure can function, but the overall thickness of the LED screen increases
Solution Approach 1:
The patent incorporates a rotatable angle adjusting mechanism that allows the locking device to dynamically adapt its connection angle. This dynamic capability enables the device to maintain functionality with reduced thickness, as the adjustable mechanism allows for compact positioning closer to the display surface while still achieving the required locking function through angular adjustment rather than fixed positioning.
4Device complexity
If the locking device uses a simple structure, then the cost and installation complexity are reduced, but the accuracy of arc splicing decreases
Solution Approach 1:
The patent incorporates pre-configured positioning features and angle markings on the locking device that guide the installation process. These preliminary positioning elements ensure accurate arc splicing by providing predetermined alignment references, allowing the simple structure to achieve high precision without requiring complex adjustment mechanisms during installation.
