Mobile Terminal Fluid Movement Port for Ingress Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals face performance and reliability issues due to fluid ingress, which complicates waterproofing and increases manufacturing costs, as existing designs struggle to efficiently guide and discharge fluids without additional components.
Innovation Solution
A mobile terminal structure featuring fluid movement ports with grooves and coatings to guide fluid along the surface, dispersing and evaporating it, and a fluid discharge pipe to prevent fluid from affecting internal components, while maintaining waterproof performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a high waterproof specification is applied to block fluid from flowing into the terminal, then the reliability is improved, but the manufacturing cost increases
Solution Approach 1:
The fluid movement port utilizes the terminal's existing structural features (front case, display gap) to guide and discharge fluid autonomously without requiring additional waterproofing components. The system serves itself by using natural fluid flow and evaporation processes to prevent fluid accumulation, thereby achieving waterproof performance without increasing manufacturing cost
Solution Approach 2:
The invention extracts the fluid discharge function from the traditional waterproofing system. Instead of adding complex waterproof seals and barriers, the patent creates a dedicated fluid movement port that actively channels and removes fluid from the terminal interior, separating the fluid management function from the structural components
2Reliability
If additional members are added to guide and discharge fluid, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The fluid movement port is designed to perform multiple functions using a single structural element. It simultaneously serves as a structural component of the front case, a fluid guidance channel, and a discharge port. The groove structure within the fluid movement port provides both structural integrity and fluid directing functionality, eliminating the need for separate guiding components
Solution Approach 2:
The invention merges the fluid guidance and discharge functions into the existing front case structure. The fluid movement port is integrated directly into the front case with grooves formed as part of the case structure itself, combining what would traditionally be separate components (housing, fluid channels, discharge ports) into a unified structure
3Productivity
If the cross-sectional area of fluid movement port is increased, then the evaporation efficiency is improved, but the device complexity increases
Solution Approach 1:
The invention increases the effective cross-sectional area for fluid evaporation by utilizing the depth dimension of the front case structure. The groove in the fluid movement port extends in the depth direction, creating a three-dimensional fluid reception space that increases surface area for evaporation without requiring larger lateral dimensions or additional components
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 solution effectively prevents fluid from affecting internal components, enhances reliability, and maintains waterproof performance without increasing manufacturing costs by guiding and evaporating fluid ingress, thus improving the terminal's durability and functionality.
Implementation Method 1
a coating member made of a polymer material may be configured to cover a surface of each of the fluid movement ports, thereby efficiently moving fluid along the surface of the fluid movement ports
Implementation Method 2
increasing a cross-sectional area in which fluid moving along a fluid movement port is brought into contact with the fluid movement port to disperse and evaporate the fluid
