Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display screen unloading methods often damage lamp beads due to the use of strong magnetic tools and are cumbersome, requiring heavy and inconvenient tools for disassembly.
Innovation Solution
An unloading device with a driving mechanism and telescopic dowel bars with inclined surfaces that separate the display screen from its frame, reducing the need for magnetic tools and facilitating easy disassembly by creating a gap between components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a magnetic auxiliary screen disassembly tool is used to disassemble the display screen, then the magnet adsorption force between the display screen and the frame can be offset, but the lamp beads of the display screen are damaged by the magnetic auxiliary screen disassembly tool
Solution Approach 1:
The patent extracts the magnetic components from the disassembly tool and places them only on the display screen and frame. The disassembly tool itself becomes non-magnetic, eliminating the harmful magnetic field effect on lamp beads while maintaining the magnetic adsorption mechanism for holding components during assembly and disassembly
Solution Approach 2:
The patent introduces a non-magnetic disassembly tool as an intermediary that interfaces with the magnetic components on the display screen and frame. This mediator allows mechanical disassembly operations without introducing additional magnetic fields that could damage the lamp beads
2Ease of operation
If a magnetic auxiliary screen disassembly tool is used to disassemble the display screen, then the display screen can be disassembled from the frame, but the magnetic auxiliary screen disassembly tool has a heavier weight and is not convenient to operate
Solution Approach 1:
The patent extracts the magnetic components from the disassembly tool, leaving only the structural framework. This reduces the weight of the disassembly tool by removing the heavy magnetic elements, making it more convenient to operate while the magnetic function is provided by the components already present on the display screen and frame
Solution Approach 2:
The magnetic components on the display screen and frame serve their dual purpose: providing magnetic adsorption during assembly and creating the magnetic field interaction during disassembly. This eliminates the need for a heavy magnetic tool, as the system's own components perform the disassembly function

Implementation Method 1
the inclined surface of the dowel bar abuts with and moves along the second component, so as to separate the first component from the second component
Implementation Method 2
both the frame and the display screen are provided with a magnet, and the two are adsorbed by the magnets
