Packaging Limiter Segmentation for LCD Panel Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing packaging devices for liquid crystal panels are prone to deformation and limiter displacement during transportation, leading to potential damage due to the lack of a securing structure between the limiter and the box, causing the limiter to slide out and fail to hold the panel securely.
Innovation Solution
A packaging device with a modified limiter structure featuring a fixing portion and a limiting portion, where the fixing portion is clamped within the box and the limiting portion extends between the LCD and PCB, accompanied by an accommodation groove to secure the limiter, reducing the likelihood of deformation and displacement under stress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a limiter is used to hold the liquid crystal panel in the box, then the panel position is constrained, but the limiter may slide out when large stress is applied during transportation
Solution Approach 1:
The limiter is divided into two functional segments: a limiting portion that extends into the box to constrain the panel, and a fixing portion that remains outside the box for secure attachment. This segmentation allows each part to perform its specific function optimally while preventing the limiter from sliding out during transportation.
Solution Approach 2:
A fixing structure (such as a fixing plate or clip) is introduced as an intermediary element to connect the limiter to the box. This intermediary mechanism ensures that the limiter remains securely fixed to the box while still being able to extend into the box to hold the panel in place.
2Stability of the object's composition
If the limiter is inserted into the box to hold the panel, then the panel is constrained, but the box may be pressed and deformed under stress
Solution Approach 1:
The limiter is designed with different local characteristics: the limiting portion has specific dimensional features (length greater than thickness projection) that allow it to engage with the panel while distributing stress. This localized structural optimization enables the limiter to hold the panel securely without causing excessive deformation to the box.
3Device complexity
If no securing structure is provided between the limiter and the box, then the device complexity is reduced, but the limiter slides out when the box deforms
Solution Approach 1:
The limiter is pre-assembled with a fixing portion designed to engage with the box before the packaging process. This preliminary configuration ensures that when the box is subjected to stress during transportation, the limiter is already secured in position and cannot slide out, eliminating the need for complex real-time securing mechanisms.

AI summary
A packaging device is provided, comprising a box for accommodating object to be packaged. The packaging device further comprises a limiter located on the both sides of the inner surface of the box. The limiter includes a fixing department and a limiting department. The limiting department is connected to one side of the fixing department and extends in a direction that is far away from the fixing department. The length of the projection of the fixing department, which is projected on a vertical plane perpendicular to the limiting department, is larger than the thickness of the limiting department. The fixing department is clamped fixedly by the box, and the limiting department stretches into the box to clamp the object to be packaged. Implementing the present invention, the limiter can be prevented from sliding out and the damage to the packaged object can be avoided.
