Resilient Seal Component for Display Assembly Foreign Matter Inhibition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable terminals face challenges in maintaining operational integrity in hostile environments due to the inability of existing sealing mechanisms to effectively prevent the ingress of foreign matter such as water, moisture, and particulate matter.
Innovation Solution
A resilient seal component with a body having a base portion connected to a top portion by side portions, defining an interior channel for engaging the display, and featuring a sealing rib on either the exterior or interior surface to inhibit foreign matter penetration between the display and the seal component or the compartment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional sealing mechanisms are used, then assembly simplicity is maintained, but sealing effectiveness against foreign matter penetration deteriorates
Solution Approach 1:
The seal component is divided into multiple functional segments: a base portion for positioning, side portions forming an interior channel for engaging display edges, and a top portion for overlapping the display surface. This segmentation allows each portion to perform its specific sealing function effectively while maintaining overall structural integrity.
Solution Approach 2:
Different regions of the seal component have different properties optimized for their specific functions: the base portion provides structural support and positioning, the side portions create engagement channels with specific geometries, and the top portion provides surface sealing. The sealing ribs are strategically placed at critical locations where foreign matter penetration is most likely to occur.
2Ease of manufacture
If sealing components are customized for specific assembly processes, then assembly compatibility is improved, but manufacturing versatility deteriorates
Solution Approach 1:
The seal component design incorporates universal features that allow it to be adapted to different assembly processes and display configurations. The modular structure with base, side, and top portions can be manufactured in various orientations and configurations to suit different assembly line requirements while maintaining the same fundamental sealing mechanism.
Solution Approach 2:
The seal component is designed with flexible dimensions and geometries that can be dynamically adjusted during manufacturing to match different display sizes and compartment configurations. The resilient material properties allow the seal to adapt to slight variations in assembly tolerances across different production batches.
3Reliability
If sealing ribs are added to prevent foreign matter penetration, then sealing effectiveness is improved, but manufacturing complexity deteriorates
Solution Approach 1:
The sealing ribs are pre-formed as integral features of the mold during seal component manufacturing, rather than being added as separate components. This preliminary action ensures precise positioning and consistent geometry without requiring additional assembly steps or complex post-processing operations.
Solution Approach 2:
The sealing ribs are merged with the main seal body as a single integrated component, eliminating the need for separate sealing rib parts and their associated attachment processes. This merging simplifies manufacturing while ensuring precise alignment between the ribs and the seal component's other features.

AI summary
A display assembly for a portable terminal inhibits the penetration of foreign matter from an exterior environment into the interior of the portable terminal. The display assembly includes a display for mounting in an open-faced compartment enclosed by a bottom/top cover plate. A resilient seal component of the display assembly is positioned between the display and the compartment, the seal component including a body including a base portion connected to a top portion by side portions for defining an interior channel for engaging the sides of the display, once received therein. A top portion of the seal component is adapted for overlapping a portion of the top surface of the display and the base portion for overlapping at least a portion of the bottom surface of the display.
