Cell Box Protruding Portions Prevent Protective Sheet Lift
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cell box designs require separate installation of protective sheet removing devices, which is costly and can lead to the protective sheet being lifted up along with the display panel during removal, causing interruptions in the display panel removal process.
Innovation Solution
A cell box design featuring a bottom portion with protruding portions that extend into secondary spaces within the housing, preventing the protective sheet from being lifted up by catching it when the display panel is removed, thus ensuring the protective sheet remains within the cell box.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective sheet removing device is separately installed to prevent the protective sheet from being lifted up, then the reliability of the removal process is improved, but the device complexity and cost increase
Solution Approach 1:
The patent merges the protective sheet removal function with the display panel removal device by integrating a protective sheet removing portion into the removal device. This allows both the protective sheet and display panel to be removed using a single integrated device, eliminating the need for separate devices and reducing overall system complexity while maintaining reliable removal functionality
Solution Approach 2:
The removal device is designed with multi-functionality, where a single device performs both protective sheet removal and display panel removal operations. The protective sheet removing portion and display panel removing portion work together in one integrated system, making the device versatile and eliminating the need for multiple specialized devices
2Reliability
If a separate protective sheet removing device is installed to prevent the protective sheet from being lifted up, then the removal process reliability is improved, but the cost increases
Solution Approach 1:
By combining the protective sheet removing portion and display panel removing portion into a single integrated device, the patent reduces the total number of components that need to be manufactured and assembled. This merging approach lowers manufacturing costs while ensuring reliable removal of both the protective sheet and display panel
3Ease of operation
If the protective sheet is allowed to be removed freely with the display panel, then the ease of operation is improved, but the protective sheet may be lifted up causing process interruptions
Solution Approach 1:
The removal device is segmented into distinct functional portions: a protective sheet removing portion and a display panel removing portion. This segmentation allows each portion to be optimized for its specific function while working together in a coordinated manner, ensuring simple operation without compromising reliability
Solution Approach 2:
The protective sheet removing portion is designed to remove the protective sheet in advance before the display panel removal. This preliminary action prevents the protective sheet from being lifted up during the subsequent display panel removal process, ensuring smooth and reliable operation throughout the entire removal sequence

AI summary
A cell box includes a bottom portion defining a bottom surface of a housing space in which a display panel and a protective sheet are housed in an overlapping manner, and a side wall portion defining a side surface of the housing space. The housing space includes a first space in which the display panel is disposed and a second space in which the display panel is not disposed and a part of the protective sheet is disposed, one or more protruding portions protruding into the second space are provided in the bottom portion, the protruding portions include a first portion extending in a normal direction of the bottom surface and a second portion more distant from the bottom surface than the first portion is, and the second portion includes an overhanging portion more overhanging than the first portion when viewed from the normal direction of the bottom surface.
