Display Tray Corner Buffers for OLED Edge Impact Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices, particularly those with organic light-emitting diode (OLED) displays, are vulnerable to damage from impact forces during handling and transportation due to the use of hard guides that do not adequately protect the edge areas.
Innovation Solution
A tray design featuring corner buffer members that compress and deform during collisions, reducing impact forces by extending the duration of collision and protecting the edge areas of display devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If hard guides made of the same material as the tray are used to support display devices, then the guides can provide structural support and stability, but the hard material cannot adequately absorb impact forces, making edge areas of display devices vulnerable to damage during shipping and transport
Solution Approach 1:
The patent applies local quality by differentiating the material properties of different tray components. While the main tray body remains hard for structural support, the corner buffer members are made of soft, compressible material specifically at the corner locations where impact damage is most likely to occur. This localized material differentiation allows the tray to simultaneously provide structural strength and impact protection at critical areas.
Solution Approach 2:
The corner buffer members are pre-installed at the corner positions of the tray before display devices are loaded. These soft buffer members are positioned in advance to cushion and absorb impact forces that may occur during shipping and transport, protecting the edge areas of display devices from damage before any impact event occurs.
2Productivity
If multiple display devices are loaded and transported together in stacked trays to improve loading efficiency, then productivity increases, but the risk of impact and vibration damage to individual devices increases due to reduced protection per device
Solution Approach 1:
The patent segments the protection function by providing individual corner buffer members at each corner of the tray, rather than relying on a single continuous protective structure. This segmentation allows each corner to independently absorb impact forces, ensuring that even when multiple trays are stacked and transported, each display device receives dedicated protection at its vulnerable edge areas, maintaining protection effectiveness while enabling high-density loading.
3Object-affected harmful factors
If soft buffer material is used for corner protection, then impact forces can be absorbed, but the buffer material may compress too much under normal loading conditions, causing instability during transport
Solution Approach 1:
The patent applies parameter changes by carefully selecting and designing the corner buffer members with specific physical properties - using soft, compressible material that has appropriate elasticity and recovery characteristics. The buffer members are designed to compress sufficiently during impact events to absorb energy, yet maintain enough structural integrity and elastic recovery to prevent excessive compression under normal loading conditions, thus maintaining transport stability while providing impact protection.
