Floor Cleaner Power Switch Design for Fluid Contact Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor cleaners face the issue of fluid accidentally contacting the power switch, potentially causing electrical malfunctions due to spills or drips from the user's hand when operating the device.
Innovation Solution
The floor cleaner incorporates a power switch design with a frame and button configuration that includes a fluid collection surface and outlet, directing any fluid away from the electrical components, ensuring that fluid is inhibited from passing through the button aperture and instead directed to a drain, thus preventing contact with electrical parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the power switch is made easily accessible for operation, then ease of operation is improved, but the risk of fluid contact with electrical components increases
Solution Approach 1:
The patent channels the harmful fluid that contacts the power switch into a beneficial drainage system. The fluid collection surface and outlet convert the harmful fluid contact into a controlled drainage path, allowing the switch to remain accessible while protecting electrical components from fluid damage.
Solution Approach 2:
The patent introduces intermediate protective structures between the fluid and electrical components. The fluid collection surface, wall, and outlet act as intermediaries that intercept and redirect fluid away from the electrical components, allowing the power switch to remain accessible without exposing electronics to fluid damage.
2Reliability
If the power switch design includes fluid protection features, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent merges the fluid protection function with the existing power switch structure. The fluid collection surface, wall, and outlet are integrated into the power switch housing rather than being separate components, thereby improving reliability while minimizing increases in device complexity.
Solution Approach 2:
The power switch housing serves multiple functions: it provides the mechanical switch structure and simultaneously acts as a fluid collection and drainage system. This multi-functionality improves reliability by protecting against fluid contact while avoiding additional complexity from separate protective components.

Function Achieved in This Case
This design effectively prevents fluid from reaching the electrical components, enhancing the reliability and safety of the floor cleaner by ensuring the power switch remains functional even when used with wet hands, reducing the risk of electrical failures.
Implementation Method 1
a fluid collection surface between the inner wall and the outer wall that directs fluid on the fluid collection surface toward the fluid outlet

AI summary
A floor cleaner includes an electrically powered component and a power switch. The power switch includes a button including an actuator surface and a wall that extends away from the actuator surface. The power switch further includes a frame, the button movable relative to the frame to operate the power switch. The frame includes an inner wall that defines a button aperture, the button extending into the button aperture, an outer wall, a fluid outlet, and a fluid collection surface between the inner wall and the outer wall that directs fluid on the fluid collection surface toward the fluid outlet. The wall of the button is received in a gap between the inner wall and the outer wall of the frame so that fluid is directed along the wall of the button to the fluid collection surface and inhibited from passing through the button aperture.
