Humidifier Display Placement to Reduce Electrical Leakage Risk
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing upward discharge type large-capacity humidifiers face challenges in safely connecting and powering displays due to their peripheral placement, leading to potential electrical leakage and safety risks.
Innovation Solution
The humidifier design includes a display positioned on the side of the humidifying device, with a coupling cover extending to cover the display housing, and a molding member to isolate it from moisture, reducing the risk of submersion and improving waterproof performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display is disposed on the peripheral exterior wall of the main body, then the display is accessible to users, but electrical connection to the machine room becomes difficult and electric energy may leak to the water storage space
Solution Approach 1:
An insulating plate is introduced as an intermediary component between the display and the water storage space. The insulating plate prevents direct electrical contact between the display and water, eliminating the risk of electric energy leakage to the water storage space while maintaining the display's peripheral placement for user accessibility.
Solution Approach 2:
The insulating plate acts as a thin film barrier that physically separates the display from the water storage space. This thin insulating barrier effectively blocks electrical energy leakage while allowing the display to remain positioned on the peripheral wall for ease of operation.
2Device complexity
If the display is disposed on the peripheral exterior wall, then the display structure is simple, but the electrical connection between display and machine room becomes difficult
Solution Approach 1:
The electrical connection is routed through a vertical path from the machine room at the bottom, through the insulating plate, to the display on the peripheral wall. This three-dimensional routing approach simplifies the overall structure by using the vertical dimension for wire passage while maintaining the display's accessible peripheral position.
3Ease of operation
If the display is placed on the peripheral wall of the water storage space, then the display is visible to users, but electric energy may leak from the display to the water stored in the water storage space
Solution Approach 1:
The insulating plate serves as a mediator that positions the display on the peripheral wall for visibility while simultaneously preventing electric energy leakage to the water storage space through its insulating properties.
Solution Approach 2:
The insulating plate converts the potential harmful effect of electrical proximity to water into a beneficial safety feature by blocking electrical energy leakage while allowing the display to remain in its optimal visible position on the peripheral wall.
