Modular Liquid Crystal Panel Case With Interchangeable Base Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid crystal panel packaging cases are heavy, inconvenient to carry, and costly to maintain due to their integral and thick structures, requiring replacement of the entire case when damaged.
Innovation Solution
A modular packaging case design featuring a frame body and interchangeable base plate with cut-out structures and reinforcement ribs, allowing for selective replacement of damaged parts and reducing weight and material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the packaging case is formed integrally with increased bottom thickness to improve structural strength, then the strength is improved, but the weight increases and maintenance cost increases
Solution Approach 1:
The packaging case is divided into separate components: a frame body and a base plate that can be independently processed and assembled. The base plate is inserted into the frame body to form the complete packaging case, allowing individual parts to be replaced if damaged rather than replacing the entire integral structure.
Solution Approach 2:
Instead of uniformly increasing the thickness of the entire base plate, the invention locally reinforces only the areas that require additional strength. Reinforcement ribs are added specifically at the four corners of the base plate where structural strength is most needed, while other areas maintain reduced thickness to minimize weight.
2Strength
If the packaging case is formed integrally with increased bottom thickness to improve structural strength, then the strength is improved, but the maintenance cost increases
Solution Approach 1:
The packaging case is divided into separate components: a frame body and a base plate that can be independently processed and assembled. The base plate is inserted into the frame body to form the complete packaging case, allowing individual parts to be replaced if damaged rather than replacing the entire integral structure.
Solution Approach 2:
The modular design allows the base plate to be easily removed and replaced when damaged, while the frame body can be retained and reused. This selective replacement approach reduces maintenance costs compared to replacing entire integral packaging cases.
3Weight of moving object
If the base plate thickness is reduced to decrease weight and material usage, then the weight is reduced, but the structural strength may be compromised
Solution Approach 1:
Instead of uniformly increasing the thickness of the entire base plate, the invention locally reinforces only the areas that require additional strength. Reinforcement ribs are added specifically at the four corners of the base plate where structural strength is most needed, while other areas maintain reduced thickness to minimize weight.
Solution Approach 2:
The base plate combines regions of different thicknesses to create a composite structure. Thinner regions reduce weight while thicker reinforced regions at the corners provide necessary structural strength, achieving an optimal balance between weight reduction and strength maintenance.

AI summary
A liquid crystal panel packaging case, including a frame body and a base plate, wherein an inside of the frame body is provided with a stepped part, and at least two opposite ends of the base plate are lapped on an upper surface of the stepped part. The packaging case the frame body and the base plate of the liquid crystal panel packaging case individually manufactured in combination. The base plate is used by being lapped on the step of the frame body. The frame body and the base plate in different packaging bases are interchangeable, so that only the damaged structure needs to be replaced when only a part is damaged, which decreases repair cost.
