Solution Overview

Problem

Display panels in small or miniature electronic devices are vulnerable to damage during manufacturing processes due to direct contact with the tray edges, leading to rubbing and potential damage.

Innovation Solution

A tray design featuring a base surface with guides and avoidance grooves that prevent line contact, ensuring surface contact and supporting the loading target element to minimize rubbing and damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the loading target element is vertically accommodated in the tray to efficiently use loading space, then space utilization is improved, but the edge surface of the loading target element directly contacts the bottom of the tray causing rubbing and damage

Engineering Contradiction:

Improvetray loading space utilizationVSAvoidrubbing damage to loading target element

Core Design Contradiction:

Volume of moving objectVSObject-affected harmful factors

Solution Approach 1:

The patent introduces guides as intermediary structures that protrude from the tray bottom. These guides act as mediators between the loading target element and the tray bottom, supporting the element at specific locations (edges or corners) rather than allowing direct contact between the element's edge surface and the tray bottom. This intermediary structure enables vertical accommodation while preventing rubbing damage.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The tray bottom is segmented into multiple contact points through the guides, which protrude at specific locations. Instead of continuous contact between the loading target element and the tray bottom, the support is divided into discrete points (edges or corners), allowing vertical positioning while minimizing contact area and preventing rubbing.

Inventive Principle:

Principle #1Segmentation

2Productivity

If multiple display devices are loaded and transported in stacked trays to improve process efficiency, then productivity is improved, but the vulnerability to damage during handling increases

Engineering Contradiction:

Improveloading efficiencyVSAvoidprotection against damage

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The guides serve as intermediary support structures that enable safe stacking of multiple trays. By supporting the loading target element at specific points (edges or corners) rather than allowing full contact, the guides prevent damage during stacking and handling. This allows multiple trays to be stacked vertically for efficient transport while maintaining protection of the display devices.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

The present disclosure relates to a tray. According to an embodiment, a tray includes: a tray bottom portion including a base surface, a guide protruding from the base surface, and an avoidance groove recessed from the base surface; and a tray sidewall portion disposed on at least one edge of the tray bottom portion. At least a partial area of the avoidance groove is disposed between the guide and the base surface.
