Symmetric Wedge-Pin Box Latch for Multi-Box Self-Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing box latches require multiple units and steps to connect and lock multiple LED boxes, leading to resource wastage and inefficiency.
Innovation Solution
A box latch with a wedge-shaped pin that moves into a wedge-shaped notch on adjacent boxes, allowing for self-locking and reducing the number of latches and steps required, featuring symmetrically arranged pins and receiving cavities for stable and flexible connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple latches are used to connect and lock multiple LED boxes, then the connection reliability is improved, but the device complexity and resource consumption increase
Solution Approach 1:
The patent combines multiple latch functions into a single latch by using a wedge-shaped pin that can simultaneously engage with wedge-shaped notches on multiple adjacent LED boxes. The wedge-shaped pin acts as a universal locking element that merges the functionality of what would traditionally require multiple separate latches, thereby reducing device complexity while maintaining connection reliability across multiple boxes.
Solution Approach 2:
The latch is designed with universal applicability through the wedge-shaped pin and notch configuration that can connect and lock multiple LED boxes of different orientations (horizontal or vertical splicing). The same latch structure serves multiple functions: connecting adjacent boxes, providing self-locking capability, and adapting to different splicing configurations without requiring additional specialized components.
2Reliability
If multiple steps are used to connect and lock adjacent display boxes, then the connection reliability is improved, but the operation time and productivity decrease
Solution Approach 1:
The wedge-shaped pin is pre-configured within the latch body, and the wedge-shaped notches are pre-formed on the LED boxes. When the latch is inserted, the wedge-shaped pin automatically engages with the notches in a single motion, eliminating the need for multiple sequential steps. The self-locking feature further ensures that the connection is securely established without requiring additional tightening or adjustment steps.
3Stability of the object's composition
If traditional latches are used to connect LED boxes, then the connection stability is maintained, but the resource consumption and cost increase
Solution Approach 1:
The patent reduces material consumption by merging multiple latch components into a single integrated latch structure. The wedge-shaped pin and latch body are designed as unified components that can secure multiple LED boxes, thereby reducing the total amount of latch material required compared to using multiple separate traditional latches for the same number of boxes.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables efficient and cost-effective connection of multiple boxes with reduced resource usage, providing a stable and flexible locking mechanism that can lock 2-4 adjacent boxes with a single latch.
Implementation Method 1
a box latch, provided with a wedge-shaped pin arranged in the box latch, wherein the wedge-shaped pin is movable into a wedge-shaped notch formed by mating parts of two spliced adjacent boxes and mating with the wedge-shaped pin to lock the two adjacent boxes

AI summary
The present invention provides a box latch. The box latch is provided with two wedge-shaped pins symmetrically arranged around its center, and the two wedge-shaped pins are movable into a wedge-shaped notch formed by mating parts of two spliced adjacent boxes and mating with the wedge-shaped pin to lock the two adjacent boxes. The two wedge-shaped pins are symmetrically arranged around its center such that only one box latch is required to lock two adjacent boxes together, reducing the number of splicing steps and box latches, further saving manpower and material resources. In addition, the wedge-shaped pin and the wedge-shaped notch are shaped and configured to mate with each other such that self-locking occurs when they are locked, thus providing a stable connection of the boxes.
