Retractable Display Position Sensing and Dust Ingress Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display apparatuses that protrude from a housing face challenges such as damage during extension and foreign substance ingress, leading to reliability issues.
Innovation Solution
A display apparatus with a housing, a protruding display panel, a lifting device, and position sensors to monitor the display's position, along with a dust collection system to prevent foreign substances from entering the housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display panel protrudes out from the housing, then the portability and installation area are improved, but the display panel may be damaged during the protrusion process
Solution Approach 1:
The patent applies beforehand cushioning by providing a guide structure and protective mechanism before the display panel protrudes. The guide structure pre-establishes a safe path for the display panel to follow during extension, preventing damage before it can occur. This resolves the contradiction by maintaining portability while preemptively protecting against display panel damage.
2Area of stationary object
If the display panel protrudes out from the housing, then the installation area is reduced, but foreign substances may flow into the housing
Solution Approach 1:
The patent uses an intermediary approach by introducing a guide structure and sealing mechanism that mediates between the need for display panel protrusion and the need to prevent foreign substance ingress. The guide structure acts as an intermediary channel that allows the display panel to extend while blocking foreign substances from entering the housing, thus resolving the contradiction between reduced installation area and prevention of harmful factors.
3Ease of operation
If the housing is opened to allow the display panel to protrude, then the display functionality is improved, but the reliability is reduced due to foreign substance ingress
Solution Approach 1:
The patent applies flexible shells and thin films by using a guide structure with sealing characteristics that allows the housing to remain partially closed while enabling display panel protrusion. This flexible sealing mechanism maintains housing integrity and prevents foreign substance ingress while still allowing the display to extend, thus resolving the contradiction between ease of operation and reliability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively prevents display panel damage and foreign substance ingress, ensuring the reliability and longevity of the display apparatus by monitoring and controlling the protrusion and cleaning the housing.
Implementation Method 1
The first position sensor and the second position sensor simultaneously sense a distance by which the display is raised
Data Source
AI summary
Disclosed herein is a display apparatus. The display apparatus includes a housing, a display configured to protrude out from the housing along a vertical axis, a lifting device configured to raise and to lower the display along the vertical axis with respect to the housing, and a position sensor disposed inside the housing and configured to sense a distance in which an upper portion of the display is moved along the vertical axis. The position sensor includes a first position sensor and a second position sensor spaced apart along a horizontal axis. The first position sensor and the second position sensor simultaneously sense a distance by which the display is raised.
