Solution Overview

Problem

Electronic devices face challenges in reducing stress caused by shock loads acting on electronic components, such as display panels, due to inertial forces during accidental drops or movements, which can lead to damage and cable entanglement.

Innovation Solution

The implementation of a housing design with strategically arranged ribs along the side surface of electronic components, where ribs closer to the edges and those in the middle portion of the component surface work together to absorb shock loads and guide cables, reducing stress and preventing damage by dispersing the load and protecting cables from entanglement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a single rib is used to absorb shock load, then the structure is simple, but the stress reduction effect is insufficient

Engineering Contradiction:
Improvestress reduction effectVSAvoidrib structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The housing is divided into multiple ribs (first rib and second rib) positioned at different locations along the side surface. The first rib is arranged closer to the edge of the electronic component while the second rib is positioned in the middle portion, creating multiple shock absorption points that collectively provide superior stress reduction compared to a single rib structure.

Inventive Principle:
Principle #1Segmentation

2Reliability

If ribs are positioned far from the electronic component, then cable routing is easier, but shock absorption effectiveness decreases

Engineering Contradiction:
Improveshock absorption effectivenessVSAvoidcable routing difficulty
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

Different ribs are positioned at different distances from the electronic component based on their specific functions. The first rib is located closer to the edge for effective shock absorption, while the second rib in the middle portion provides additional protection and cable routing guidance. This localized positioning optimizes both shock absorption effectiveness and cable management.

Inventive Principle:
Principle #3Local quality

3Reliability

If no rib arrangement is used, then the housing is simple, but cables are susceptible to entanglement during drops

Engineering Contradiction:
Improvecable protectionVSAvoidhousing structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The ribs serve as intermediary structures that mediate between the housing and the electronic component. They provide a protective interface that absorbs shock loads and guides cables, preventing direct contact between the housing and component during accidental drops, thereby protecting cables from entanglement and damage.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

According to one embodiment, an electronic device includes a housing and a plurality of ribs. The housing houses at least part of an electronic component. The ribs are arranged along a flat side surface of the electronic component in the housing such that the inner surface of the ribs faces the side surface. The ribs comprises a rib that faces the side surface of the electronic component, and another rib that is located on an edge side of the side surface compared to the rib and more distant from the side surface than the rib.
