Solution Overview

Problem

In foldable electronic devices, static electricity introduced through separation spaces between components can cause damage to the display, and existing protection members that prevent interference may increase the device's volume or reduce the display area.

Innovation Solution

A foldable electronic device with a housing that includes a protection member with non-conductive and conductive portions, and a side surface member with conductive and insulating portions, providing an electrostatic discharge path without increasing the device's size or reducing the display area.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a protection member is used to prevent static electricity damage, then display protection is improved, but device volume increases

Engineering Contradiction:
Improvedisplay protectionVSAvoiddevice volume
Core Design Contradiction:
ReliabilityVSVolume of stationary object

Solution Approach 1:

The protection member is divided into multiple conductive portions (first conductive portion, second conductive portion, third conductive portion) that are spatially separated and functionally independent. Each portion provides electrostatic discharge protection for specific regions of the display, allowing the protection member to be smaller than a single continuous structure while maintaining comprehensive coverage.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the protection member have different conductive properties tailored to local requirements. The first conductive portion extends in the length direction for side protection, the second conductive portion provides corner protection with extended reach, and the third conductive portion offers bottom protection. This localized conductivity distribution enables effective protection with minimal material usage.

Inventive Principle:
Principle #3Local quality

2Reliability

If a protection member is used to prevent static electricity damage, then display protection is improved, but display area decreases

Engineering Contradiction:
Improvedisplay protectionVSAvoiddisplay area
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The protection member is segmented into discrete conductive portions positioned only at critical areas (sides, corners, bottom) rather than forming a continuous border around the entire display. This segmentation allows maximum display area to remain visible while providing targeted electrostatic protection where it is most needed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The conductive portions are extracted from a continuous protection structure and placed only at specific locations where electrostatic discharge paths are required. This extraction eliminates unnecessary material that would reduce display area while maintaining protection effectiveness at critical points.

Inventive Principle:
Principle #2Taking out (Extraction)

3Reliability

If the conductive portion is extended to improve ESD protection, then electrostatic discharge capability is improved, but device complexity increases

Engineering Contradiction:
Improveelectrostatic discharge capabilityVSAvoidprotection member complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The protection member simultaneously serves multiple functions: it provides electrostatic discharge protection, defines the display boundary, and contributes to the device aesthetic appearance. The same conductive portions that protect against ESD also serve as visual elements of the device design, eliminating the need for separate protective and cosmetic components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The protection member is merged with the device housing structure, integrating the ESD protection function into the existing mechanical framework. The conductive portions are incorporated into the housing design rather than being separate attachments, reducing overall device complexity while maintaining protection capabilities.

Inventive Principle:
Principle #5Merging (Combining)
