Fluid Resistant Display Apparatus With Underside Drainage Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fluid exposure poses a challenge for pump drive components, leading to malfunctions, as existing technologies lack effective resistance to fluid exposure.
Innovation Solution
An enclosure assembly for a pump that includes a case cover with drainage channels on its underside surface, bosses for securing a frame plate, and a display integrated with the case cover, which diverts fluid away from the display through these channels, preventing fluid interference with the display's operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display is integrated with the case cover for better accessibility and visibility, then the ease of operation is improved, but the reliability deteriorates due to fluid exposure causing malfunction
Solution Approach 1:
A fluid-resistant coating is applied to the display surface to act as an intermediary barrier between the fluid environment and the display components. This coating allows the display to remain accessible and visible while protecting it from fluid-induced malfunctions, thus resolving the contradiction between ease of operation and reliability.
Solution Approach 2:
A thin fluid-resistant film or protective layer is integrated over the display surface. This flexible protective layer maintains the display's visibility and accessibility while preventing direct fluid contact that would cause malfunction, thereby simultaneously achieving ease of operation and reliability.
2Productivity
If the pump components are exposed to fluid for continuous operation, then the productivity is improved, but the reliability worsens due to fluid exposure causing component malfunction
Solution Approach 1:
Fluid-resistant coatings are applied to exposed pump components to create an intermediary protective layer. This allows the components to remain exposed for continuous operation while the coating prevents fluid from causing malfunction, thus resolving the contradiction between productivity and reliability.
Solution Approach 2:
The pump components utilize composite material structures that combine fluid-resistant materials with functional materials. This allows the components to maintain their operational functionality while being inherently resistant to fluid exposure, enabling continuous operation without sacrificing reliability.
3Reliability
If the display is fixedly attached to the case cover for stability, then the reliability is improved, but the ease of repair deteriorates due to difficulty in replacing the display
Solution Approach 1:
The display assembly is segmented into modular components with standardized interfaces. The display can be fixedly attached to the case cover for stability during operation, but the modular design with quick-release fasteners allows for easy separation and replacement when repair is needed, thus resolving the contradiction between reliability and ease of repair.
