Hand Pump Faucet Linkage for Flow and Temperature Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a gap between the aesthetic appeal of authentic primitive/colonial design elements and the need for practical functionality in water dispensing systems, particularly in converting hand water pumps into modern, functional faucets that maintain the authentic look and feel while providing modern era functionality.
Innovation Solution
A hand pump faucet design incorporating a pump housing, a pump handle that can be tilted and rotated, a cartridge valve for controlling water flow and temperature, and a coupling device to translate these motions, allowing for both on/off and temperature adjustments, while maintaining the authentic look and feel of a hand water pump.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If authentic hand water pump design is used, then aesthetic appeal and primitive/colonial design authenticity is improved, but functionality and ease of operation deteriorates
Solution Approach 1:
The patent merges the authentic hand water pump design with modern faucet functionality by integrating a cartridge valve mechanism within the pump housing. The pump handle is modified to incorporate both the aesthetic elements of a primitive pump and the operational features of a modern lever faucet, allowing users to tilt the handle for flow control and rotate it for temperature adjustment.
Solution Approach 2:
The pump handle serves multiple functions: it maintains the aesthetic appearance of a traditional hand pump while simultaneously providing modern faucet operations including flow control through tilting and temperature adjustment through rotation. The cartridge valve system enables both on/off control and temperature mixing functions within a single mechanism.
2Ease of operation
If authentic hand water pump is converted to modern faucet, then modern functionality is improved, but design authenticity and original appearance deteriorates
Solution Approach 1:
The patent applies local quality by making minimal modifications to the pump handle and housing that preserve the overall authentic appearance. The cartridge valve is contained within the existing pump housing, and the handle modifications are localized to the connection point, leaving the majority of the authentic design intact while adding modern functionality.
Solution Approach 2:
The coupling device acts as an intermediary between the pump handle and the cartridge valve, translating the handle's tilting and rotating motions into valve operations. This intermediary mechanism allows modern faucet functionality to be achieved without directly modifying the authentic pump components, thereby preserving design authenticity.
3Device complexity
If pump handle is directly connected to cartridge valve, then device complexity is reduced, but ease of repair and serviceability deteriorates
Solution Approach 1:
The patent segments the connection between the pump handle and cartridge valve by introducing a separate coupling device. This segmentation allows the cartridge valve to be accessed and serviced independently from the pump handle, improving repairability while maintaining overall structural simplicity. The coupling device acts as a detachable interface between the two components.

AI summary
Generally disclosed herein are unique mechanical elements implemented in a system and method to convert authentic hand water pumps into functioning water faucets or fabricate the functioning water faucet to simulate an authentic hand water pump. The operating principles and feel of a typical lever faucet have been replicated on the hand pump through use of a cartridge valve connected to a coupling clevis. The pump handle can be lifted up to turn water on and control the flow rate and can simultaneously be partially rotated clockwise or counterclockwise to select water temperature.
