Segmented Shield Can Liner for Display Device Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in protecting shield cans from external damage during transport and assembly while also ensuring that information markings on integrated circuits are accessible for operator convenience.
Innovation Solution
A liner system comprising a first and second liner with shield can protection portions, grip portions, and a connection portion, featuring a perforated line for easy separation, is attached to the shield can. The liners include a film layer and adhesive layer for secure attachment and protection, with information markings that can be displayed after the first liner is removed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a single liner is attached to the shield can to protect it during transport, then the shield can is protected from scratches and crushing, but the information markings on the integrated circuit become inaccessible
Solution Approach 1:
The liner is divided into two separate liners: a first liner that covers the central region where information markings are located, and a second liner that covers the edge region. The first liner can be removed to access information markings while the second liner remains to continue protecting the shield can during subsequent processes
Solution Approach 2:
The first liner is designed to be removable in advance to allow information markings to be accessed and read before the second liner is removed. This preliminary action enables operators to obtain necessary information while maintaining protection during transport and assembly
2Device complexity
If the liner is made as a single piece to simplify the structure, then the device complexity is reduced, but the ease of operation for accessing information and maintaining protection is worsened
Solution Approach 1:
The liner system is segmented into a first liner and a second liner with distinct functions. The first liner is designed for easy removal to access information, while the second liner provides continued protection. This segmentation simplifies the operational sequence despite having multiple components
Solution Approach 2:
The liner system transitions from a static single-piece structure to a dynamic multi-stage structure where the first liner can be selectively removed while the second liner remains. This dynamic approach allows the system to adapt to different operational requirements at different stages
3Object-affected harmful factors
If the liner completely covers the shield can to maximize protection, then the shield can is fully protected, but the information markings become inaccessible
Solution Approach 1:
The coverage is segmented spatially: the first liner covers the central region containing information markings, while the second liner covers the edge region. This allows selective removal of the first liner to access information while maintaining edge protection
Solution Approach 2:
Different regions of the shield can are protected by different liners with different properties. The first liner is designed for easy removal in the central region, while the second liner provides durable protection at the edges. Each region has the appropriate protection level for its specific needs

AI summary
Provided are a liner and a display device including the same. The liner includes a first liner including a first shield can protection portion, a first grip portion, and a connection portion coupling the first shield can protection portion to the first grip portion, a second liner including a second shield can protection portion and a second grip portion, and a perforated line formed along a boundary between the first liner and the second shield can protection portion.
