ABS Tray with Groove-Protrusion Lock for Panel Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional trays for liquid crystal display panels have low impact resistance, are difficult to manufacture in various sizes, and lack effective fixation, leading to potential faults during panel transfer.
Innovation Solution
A tray design featuring a tray mold frame made of acrylonitrile-butadiene-styrene (ABS) resin with extrusion bars, molding members, a receiving member, and a slot member, which includes a groove and protruding parts to prevent movement, along with an absorption member like silica gel to prevent moisture-related faults, and a supporting member for enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the tray is formed in styrofoam (EPS or EPP), then the tray is easy to manufacture, but the impact resistance is low
Solution Approach 1:
The tray is constructed using composite materials: the frame is made of ABS resin (a strong, impact-resistant plastic) while the bottom panel uses corrugated cardboard (providing cushioning and structural support). This combination maintains ease of manufacture through modular assembly while significantly improving impact resistance compared to pure styrofoam construction.
2Strength
If the tray is formed in injection molding method, then the tray structure is strong, but it is difficult to apply with various sizes of display panel and manufacture cost increases
Solution Approach 1:
The tray is divided into separate modular components: a frame structure made of ABS resin and a bottom panel made of corrugated cardboard. This segmentation allows the same frame design to accommodate different panel sizes by simply changing the bottom panel dimensions, maintaining structural strength while improving adaptability to various display panel sizes.
3Device complexity
If the slot member is not fixed on the tray, then the tray structure is simple, but the panel movement is not prevented and the tray may be easily broken
Solution Approach 1:
The slot member is pre-fixed to the bottom panel of the tray during manufacturing. This preliminary action ensures that the slot member is securely attached before the tray is used to hold display panels, preventing panel movement and tray breakage while maintaining relatively simple overall structure.

AI summary
A tray for transferring a panel is disclosed. The tray includes a tray mold frame including acrylonitrile-butadiene-styrene (“ABS”) resin, a receiving member, a supporting member and a slot member. The tray mold frame includes four extrusion bars and four molding members. The molding members combine with the extrusion bars. Each of the molding members include a first protruding part on a side surface. The receiving member is disposed inside of the tray mold frame. The supporting member is disposed on a lower surface of the receiving member. The supporting member combines with the extrusion bars configured to support the receiving member. The slot member includes a first groove combining with the first protruding part. The slot member is disposed on the receiving member. Thus, when the panel is transferred by the tray, a fault of the panel during transferring may decrease.
