Solution Overview

Problem

Conventional onboard hanging-type displays require the entire unit to be detached from the aircraft's interior trimming panel for screen replacement and maintenance, leading to complex and time-consuming processes with high labor intensity and costs.

Innovation Solution

A detachable display screen design where the screen is electrically and mechanically connected to a servo body via a detachable structure, allowing for separate detachment and easy maintenance without disassembling the entire display, using a rotating shaft with a connecting member and secure screw or snap joint connections for stability and quick assembly/disassembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of repair

If the entire onboard hanging-type display is detached from the interior trimming panel for screen replacement, then the display screen can be maintained, but the assembling and disassembling process becomes complicated and maintenance time increases

Engineering Contradiction:
Improvedisplay screen maintenanceVSAvoidmaintenance time
Core Design Contradiction:
Ease of repairVSLoss of time

Solution Approach 1:

The display system is divided into two independent segments: the servo body (motor assembly) and the display screen. The display screen is equipped with a connecting member that can be detached from the servo body, allowing the screen to be separated and maintained independently without removing the entire display unit from the aircraft interior trimming panel.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The display screen is extracted as a separate maintainable component from the integrated display system. By providing a detachable connecting member between the servo body and display screen, the screen can be taken out for maintenance while the servo body remains installed in the aircraft interior trimming panel.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of repair

If the entire onboard hanging-type display is detached from the interior trimming panel for screen replacement, then the display screen can be maintained, but labor intensity and maintenance costs increase

Engineering Contradiction:
Improvedisplay screen maintenanceVSAvoidmaintenance operation
Core Design Contradiction:
Ease of repairVSEase of operation

Solution Approach 1:

The display system is divided into two independent segments: the servo body (motor assembly) and the display screen. The display screen is equipped with a connecting member that can be detached from the servo body, allowing the screen to be separated and maintained independently without removing the entire display unit from the aircraft interior trimming panel.

Inventive Principle:
Principle #1Segmentation

3Ease of repair

If a detachable connection is used between the display screen and servo body, then maintenance becomes easier, but connection stability may be compromised

Engineering Contradiction:
Improvedisplay screen maintenanceVSAvoidconnection stability
Core Design Contradiction:
Ease of repairVSReliability

Solution Approach 1:

The connecting member is pre-equipped with positioning structures and connection features that ensure proper alignment and stable connection when attaching the display screen to the servo body. The rotating shaft includes a connecting member with structures that facilitate reliable attachment before use.

Inventive Principle:
Principle #10Preliminary action

4Device complexity

If a simple rotating shaft connection is used, then the structure occupies less space and is easier to adjust, but connection firmness may be reduced

Engineering Contradiction:
Improveconnection structureVSAvoidconnection firmness
Core Design Contradiction:
Device complexityVSStrength

Solution Approach 1:

The connecting member is pre-equipped with positioning structures and connection features that ensure proper alignment and stable connection when attaching the display screen to the servo body. The rotating shaft includes a connecting member with structures that facilitate reliable attachment before use.
