Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If display devices are loaded into packaging trays for transportation, then transportation efficiency is improved, but display devices may move within the packaging box due to vibration or impact causing damage
Solution Approach 1:
Cushion pads are pre-positioned between and on display devices before transportation occurs. These pads create a cushioning effect that absorbs vibration and impact forces, preventing device movement and damage while maintaining efficient packaging tray loading for transportation.
Solution Approach 2:
Cushion pads serve as intermediary elements between display devices and the packaging tray environment. These pads mediate the interaction between devices and external forces (vibration, impact), isolating the devices from harmful effects while allowing efficient transportation.
2Reliability
If cushion pads are added between display devices, then device movement is prevented, but packaging assembly complexity increases
Solution Approach 1:
Multiple cushion pads are combined within the packaging assembly, with each pad having integrated wing structures that can engage with protrusions on multiple sides. This merging of cushioning and positioning functions into single components provides effective device stabilization without proportionally increasing assembly complexity.
Solution Approach 2:
The cushion pads feature asymmetric wing structures where the first wing has different sub-wing configurations (first, second, and third sub-wings with varying widths) to match the asymmetric positioning requirements of display devices. This asymmetric design enables precise device positioning while maintaining reasonable structural simplicity.
3Manufacturing precision
If cushion pads with wing structures are used, then device positioning precision is improved, but cushion pad manufacturing complexity increases
Solution Approach 1:
Each cushion pad is segmented into a body and multiple wings (first wing with first, second, and third sub-wings; second wing; third wing). This segmentation allows the cushion pad to achieve complex positioning geometries for high positioning precision while potentially simplifying manufacturing through modular design and injection molding processes.

AI summary
A display device packaging assembly includes: a packaging tray including a wall defining an accommodating space, and cushion pads disposed between and on display devices loaded in the accommodating space. Each of the cushion pads includes a body and a first wing disposed on one side of said body, and the first wing includes a first sub-wing, a second sub-wing, and a third sub-wing disposed between the first sub-wing and the second sub-wing. In a first direction, a width of the third sub-wing is smaller than each of a width of the first sub-wing and a width of the second sub-wing.
