Grooved Shock-Absorbing Packing for Thin Display Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Thin display devices, such as liquid crystal display devices, face deformation and damage due to external forces like drop impacts and vibrations during transportation, as their thinner structures and narrower frames reduce their strength, leading to potential display panel dislodgment and image quality degradation.
Innovation Solution
A packing structure featuring a shock-absorbing case with a first shock-absorbing member having a groove with varying gaps between its side walls and the display panel, and a second shock-absorbing member positioned centrally, both made of elastic materials like foaming polystyrene, to absorb and distribute external forces effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the display device structure is made thinner and frames are narrowed to improve design, then the aesthetic appearance and design quality are improved, but the strength of the product decreases leading to deformation and damage during transportation
Solution Approach 1:
The patent applies beforehand cushioning by placing shock-absorbing members between the display device and packing box before transportation. The shock-absorbing members include a first member with a groove that receives the peripheral portion of the display device, and a second member disposed on the inner side of the display panel. This pre-positioned cushioning structure protects the thin display device from deformation and damage during transportation while maintaining the thin design aesthetic.
2Shape
If the frames are narrowed to improve design, then the aesthetic appearance is improved, but the overlapping portions between peripheral areas of the display panel and frame are reduced causing display panels to be dropped off during transportation
Solution Approach 1:
The patent applies segmentation by dividing the shock-absorbing structure into multiple components: a first shock-absorbing member with a groove that receives the peripheral portion of the display device, and a second shock-absorbing member disposed on the inner side of the display panel. This segmented approach provides multi-point support to the display panel, preventing it from being dropped off during transportation while maintaining the narrow frame design aesthetic.
3Reliability
If shock-absorbing members are added to protect the thin display device during transportation, then the protection against external forces is improved, but the device complexity increases
Solution Approach 1:
The patent applies universality by designing shock-absorbing members that perform multiple functions simultaneously. The first shock-absorbing member with the groove both cushions the peripheral portion of the display device and provides structural support. The second shock-absorbing member on the inner side both protects the display panel from impact and maintains its position. This multi-functional design provides comprehensive protection while minimizing the number of separate components needed.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The packing structure effectively reduces deformation and damage to the display panels by distributing impact forces through a step-wise contact with shock-absorbing surfaces, preventing panel dislodgment and maintaining image quality during transportation.
Implementation Method 1
a shock-absorbing structure stored in the packing case together with the thin display device so as to be interposed between the thin display device and the packing case
Implementation Method 2
The side wall of the groove formed in the first shock-absorbing member includes a plurality of shock-absorbing surfaces with different gaps with the display panel

AI summary
A packing structure for a liquid crystal display device includes a packing box for storing the liquid crystal display device and shock-absorbing members. The shock-absorbing members are stored in the packing box together with the liquid crystal display device so as to be interposed between the liquid crystal display device and the packing box. A side wall of a groove of the shock-absorbing member has a plurality of shock-absorbing surfaces with the gap with the display panel larger in the inside of the display panel than in the outside of the display panel. A central shock-absorbing member is disposed on the inside of the display panel deeper than the shock-absorbing face. The gap between the central shock-absorbing member and the display panel is larger than that between the shock-absorbing face and the display panel.
