Buffering Stop Structure for LCD Packing Case
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional packing cases for liquid crystal displays (LCDs) have high manufacturing costs and may cause environmental pollution due to material difficulties and decomposition issues, while also requiring effective buffering to protect the fragile LCDs from impact.
Innovation Solution
A buffering stop structure is introduced at the connecting corners of the packing case, comprising a fixing portion, a connecting portion, and a case buffering portion made of expanded polypropylene, which engages with a rib structure and contacts the LCD panel to absorb external impact, reducing the force transmitted to the LCD and case.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If EPP material is used for the case main body, then the buffering effect is improved, but the manufacturing cost increases and the shrinkage rate becomes larger making size control difficult
Solution Approach 1:
The case main body is divided into two parts: the frame structure made of recyclable plastic material and the buffering stop structures made of EPP material. This segmentation allows each component to use the most appropriate material for its function without the drawbacks of using EPP for the entire case.
Solution Approach 2:
EPP material is applied locally only at the buffering stop structures where impact protection is most needed, rather than using it for the entire case main body. This localized application reduces overall material cost while maintaining buffering effectiveness at critical corners.
2Ease of manufacture
If EPO material is used for the case main body, then the manufacturing cost is reduced, but the material is difficult to decompose causing environmental pollution
Solution Approach 1:
The packing case uses a composite material system: the frame structure uses recyclable plastic material while the buffering stop structures use EPP material. Both materials are environmentally friendly and recyclable, avoiding the pollution problems of traditional EPO while maintaining cost-effectiveness.
3Reliability
If traditional stuffing is used to fill unused spaces, then the buffering effect is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The buffering stop structures are pre-installed at the four corners of the case main body frame, providing impact protection before the LCD panel is even placed in the case. This preliminary protection eliminates the need for additional stuffing materials to fill spaces.
Solution Approach 2:
The invention extracts the buffering function from the general case body stuffing and concentrates it into specific buffering stop structures at the corners, where impact forces are most likely to occur. This simplifies the overall structure while maintaining protection effectiveness.
