Weatherproof Rocker Switch Cover With Positive On-Off Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Weatherproof switch covers for rocker style switches in damp or wet environments lack visual indication of the switch's on or off position, making it difficult for users to determine the switch's status.
Innovation Solution
A weatherproof switch cover design featuring a rocker arm mechanism with a movable membrane providing tactile feedback and a sealing mechanism, allowing users to feel the switch's position change between on and off, while maintaining a weatherproof seal, and can be adapted for single or multi-gang configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a flat rubber membrane is used to cover the entire switch for weatherproofing, then weatherproofing is achieved, but visual indication of switch position is lost
Solution Approach 1:
The patent applies color changes by incorporating a visible indicator element that changes color or displays different colors to indicate the switch position. The indicator is positioned to be visible through or beyond the membrane, allowing users to determine whether the switch is on or off without compromising the weatherproof seal.
2Reliability
If a sealed membrane covers the forwardly projecting toggle lever, then weatherproofing is achieved, but tactile feedback and visual position indication are lost
Solution Approach 1:
The patent applies segmentation by dividing the switch cover into distinct functional zones: a sealed membrane portion for weatherproofing and a separate indicator portion that remains visible and accessible. The rocker arm mechanism is segmented to provide tactile feedback through controlled movement while maintaining the seal integrity.
Solution Approach 2:
The patent uses color changes in the indicator element to provide visual feedback about switch position. The indicator is designed to be visible through the membrane or positioned at the edge, changing appearance based on the rocker arm position, thus maintaining ease of operation while preserving weatherproofing.
3Shape
If decorator rocker switches are used for aesthetic purposes, then appearance is improved, but weatherproofing capability is reduced
Solution Approach 1:
The patent merges the aesthetic decorator rocker switch design with weatherproofing functionality by integrating a sealed membrane cover that conforms to the decorative appearance while providing environmental protection. The rocker arm and indicator mechanisms are combined within the sealed structure, allowing decorative switches to function reliably in damp or wet environments.
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
Enables the use of decorator rocker switches in wet environments with clear tactile feedback for switching positions, ensuring a secure and functional weatherproof seal.
Implementation Method 1
a membrane provided below the rocker arm, the membrane providing a weatherproof seal
Implementation Method 2
a rocker arm provided in the base plate and movable between a first position and a second position
