Water Dispenser Filter Access With Pivoting Service Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water dispensing fixtures lack unobstructed visibility and ergonomic access to filters, making filter replacement cumbersome and inefficient.
Innovation Solution
A liquid dispensing system with filters positioned between 27 and 72 inches above the ground, providing unobstructed visibility and access, and a service cover or alcove that pivots for easy access, along with configurable filtration options including sequential or independent filtering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If filters are positioned in a conventional location within the water dispensing fixture, then the structure remains compact, but visibility and access to filters are obstructed, making filter replacement cumbersome
Solution Approach 1:
The filter assembly is repositioned from a conventional horizontal arrangement to a vertical arrangement above the spigot. This dimensional change allows the filter to be positioned in an upper portion of the fixture where it is visible and accessible to users standing in front of the fixture, while maintaining a compact overall structure through vertical space utilization.
Solution Approach 2:
The service cover is designed to pivot between a closed position (covering the filter assembly) and an open position (providing access to the filter). This dynamic element allows the fixture to transition between a compact enclosed state and an accessible service state, resolving the contradiction between structural compactness and ease of filter replacement.
2Ease of operation
If filters are positioned higher for better visibility and access, then user ergonomics improve, but the distance from ground surface increases requiring taller fixture installation
Solution Approach 1:
By transitioning from horizontal to vertical arrangement, the filter is positioned at an optimal height above the spigot that provides good visibility and access for standing users. The vertical configuration allows the filter to be positioned in the user's line of sight without requiring the entire fixture to be installed at excessive heights from the ground.
3Ease of repair
If a service cover is added to provide filter access, then filter replacement becomes easier, but the device complexity increases
Solution Approach 1:
The service cover pivots on a hinge to provide access to the filter assembly. This simple dynamic mechanism allows the cover to swing open for filter replacement and swing closed for normal operation, providing ease of maintenance with minimal added complexity. The pivot mechanism is a straightforward mechanical connection that does not require motors, sensors, or complex linkages.
Solution Approach 2:
The service cover acts as an intermediary element between the user and the filter assembly. It provides a protected enclosure for the filter while allowing controlled access when needed. The cover serves as a mediator that balances the need for fixture enclosure with the need for maintenance access.
