Caravan Fitting Switching Element Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile fluid fittings for vehicles like mobile homes, caravans, and boats require a compact and fail-safe design that prevents wetting of switching elements and reduces the risk of cable damage, as they often lack sufficient installation space and are prone to failure due to wetting and mechanical stress.
Innovation Solution
A faucet design with a cartridge and actuating element where the switching element is positioned below the cartridge, allowing for a slimmer and more compact configuration, preventing wetting, and using a force-transmitting lever element to activate the switching element, which can be contacted directly or magnetically for wear-free operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the switching element is integrated into the actuating element or arranged next to it, then the fitting can be operated, but the fitting becomes larger and the switching element is prone to wetting and cable damage
Solution Approach 1:
The switching element is positioned below the cartridge in the longitudinal direction, utilizing the vertical space rather than horizontal space. This dimensional repositioning protects the switching element from wetting while maintaining a compact fitting size, as the cartridge's longitudinal extension provides natural protection from fluid flow
Solution Approach 2:
The switching element is arranged within the longitudinal extension of the cartridge, nesting it in a protected position. The cartridge body acts as a protective structure that shields the switching element from direct fluid exposure while the actuating element extends to provide access for operation
2Reliability
If the switching element is arranged below the cartridge, then the fitting becomes compact and the switching element is protected from wetting, but the actuating element must extend further to reach it
Solution Approach 1:
The actuating element is designed with flexible positioning capability, allowing it to extend and reach the switching element positioned below the cartridge. The actuating element can be adjusted in length or configuration to bridge the gap while maintaining a compact overall fitting structure
3Ease of operation
If the switching element is permanently moved with the handle, then the switching function is maintained, but the cable experiences heavy stress and may break
Solution Approach 1:
The switching element is extracted from the moving handle assembly and positioned separately below the cartridge. This separation means the switching element remains stationary relative to the cartridge body, eliminating the cable stress caused by repeated handle movement while maintaining the switching function through the actuating element's ability to reach and actuate it
