Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of mounting and dismounting boxes in traditional LED display screens due to the need for tools like wrenches, resulting in low assembly efficiency.
Innovation Solution
A connecting structure comprising a first pressing plate, a second pressing plate, a connecting column, and a lifting mechanism, where the second pressing plate moves relative to the first pressing plate using a handle and spiral lifting groove, allowing for tool-free locking and unlocking of adjacent boxes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a threaded structure is used to connect boxes, then the connection is reliable, but the mounting and dismounting process becomes complicated and requires tools
Solution Approach 1:
The patent replaces the traditional threaded mechanical connection system with a lifting mechanism that uses vertical movement and elastic locking. The connecting column moves vertically within the mounting hole, and the lock sheet with elastic member automatically locks when the column reaches the bottom, eliminating the need for threading operations and tools.
Solution Approach 2:
The elastic member (lock sheet) automatically engages with the mounting hole structure to lock the connecting column in place without requiring additional fastening operations. The system self-locks through the elastic deformation and recovery of the lock sheet, making the connection process self-servicing and tool-free.
2Reliability
If a threaded structure is used to connect boxes, then the connection is secure, but assembly efficiency decreases due to complicated steps
Solution Approach 1:
The patent replaces the multi-step threaded fastening system with a single vertical insertion motion followed by automatic elastic locking. The connecting column is simply inserted into the mounting hole, and the lock sheet automatically secures it, reducing assembly operations to a single intuitive motion that significantly improves productivity.
Solution Approach 2:
The patent extracts the complex threading operation from the connection process, leaving only the essential vertical insertion motion. The locking function is separated and automated through the elastic member, which automatically engages without requiring the operator to perform additional fastening steps.
3Stability of the object's composition
If a traditional locking mechanism is used, then the connection is stable, but the device complexity increases due to additional components
Solution Approach 1:
The patent merges the locking function directly into the connecting column and mounting hole structure. The lock sheet is integrated as part of the column assembly, and the elastic member is positioned within the mounting hole itself, eliminating the need for separate locking components and reducing overall structural complexity.
Solution Approach 2:
The connecting column serves multiple functions: it provides the structural connection, guides the locking action, and works with the elastic member to achieve stable locking. The mounting hole similarly serves as both the insertion path and the locking engagement structure, reducing the need for additional specialized components.
