Solution Overview

Problem

The existing tray devices in electronic devices require additional space for eject pins, which hinders the slimming of devices and complicates antenna design due to the side-mounted eject bars.

Innovation Solution

The tray device design includes an eject bar positioned at least partially overlapping the tray body, reducing the tray's mounting space and improving peripheral electrical structure performance by integrating the eject bar within the tray socket, allowing for a more compact design and enhanced antenna functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If eject bars are disposed side by side outside the tray socket, then the ejecting operation can be performed, but the tray cover requires additional space for pin insertion hole, increasing the mounting space and hindering device slimming

Engineering Contradiction:
Improveejecting operationVSAvoidmounting space of tray
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The eject bar is repositioned from a lateral arrangement (side by side outside tray socket) to a vertical/stacked arrangement (overlapping tray body when viewed from above). This dimensional change allows the eject bar to be located in the depth direction rather than occupying lateral space, enabling the pin insertion hole to be positioned without increasing the overall mounting area of the tray.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If eject bars are disposed side by side outside the tray socket, then the ejecting structure can be implemented, but the mounting space occupied by tray causes difficulty in designing antenna radiator

Engineering Contradiction:
Improveejecting structureVSAvoidmounting space of tray
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

By changing the spatial arrangement of the eject bar from lateral to vertical stacking, the tray's footprint area is reduced. This creates more available space in the lateral direction for antenna radiator design, allowing the antenna to be properly configured without being constrained by the eject bar's mounting space requirements.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of operation

If tray cover provides additional space for pin insertion hole, then the ejecting pin can be guided, but the width of tray cover increases, contributing to larger device dimensions

Engineering Contradiction:
Improvepin insertion hole guidanceVSAvoidwidth of tray cover
Core Design Contradiction:
Ease of operationVSLength of moving object

Solution Approach 1:

The pin insertion hole is repositioned from a lateral location (requiring additional width) to a vertical location (within the depth dimension). This allows the ejecting pin to be guided through the tray cover in the depth direction rather than requiring extra lateral space, maintaining a compact tray cover width while preserving the ejecting function.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
