Pump assembly carrying rasp
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pump assemblies are not adapted to generate or dispense solid particulate materials, limiting their functionality in products like hand soap and cleaners that require simultaneous dispensing of both liquid and solid components.
Innovation Solution
A pump assembly that includes a rasp member moving relative to a block of solid material to disengage particles, which are then dispensed along with a liquid, using a linkage mechanism for coordinated movement of the rasp and pump members, allowing for the selection between coupled and uncoupled conditions for particle dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional pump assembly is used, then the structure is simple and easy to manufacture, but it cannot dispense solid particulate materials
Solution Approach 1:
The patent combines a traditional pump assembly with a rasp member and solid material block into a single integrated device. The pump member and rasp member work together in coordinated movement to achieve both liquid pumping and solid particle generation functions within one assembly, thereby expanding adaptability without proportionally increasing complexity.
Solution Approach 2:
The pump assembly is designed to perform multiple functions: pumping liquid through the fluid outlet and simultaneously generating solid particles through the rasp member's interaction with the solid material block. This multi-functionality allows a single device to handle both liquid and solid material dispensing requirements.
2Adaptability or versatility
If a rasp member is added to the pump assembly, then solid particles can be dispensed, but the device complexity increases
Solution Approach 1:
The linkage mechanism dynamically couples the movement of the pump member with the rasp member, allowing the system to automatically coordinate their motions. This dynamic coupling ensures that when the pump member moves to dispense liquid, the rasp member simultaneously moves to generate solid particles, maintaining ease of operation through automated coordination rather than requiring manual control of multiple components.
3Productivity
If the pump member and rasp member are mechanically linked, then coordinated movement is achieved, but the manufacturing complexity increases
Solution Approach 1:
The linkage mechanism is designed as a segmented, modular connection system that links the pump member and rasp member through discrete, manageable components. This segmentation allows for easier manufacturing and assembly compared to a fully integrated monolithic structure, as each component can be produced and tested independently before final assembly.

Function Achieved in This Case
Enables the efficient and concurrent dispensing of both liquid and solid materials, improving user experience and product delivery by ensuring easy and effective dispensing of solid particles with the liquid, enhancing the functionality of pump assemblies in various applications.
Implementation Method 1
a rasp moves relative a block of solid material to disengage particles of the solid material
Implementation Method 2
particles drop under gravity downwardly adjacent the fluid outlet

AI summary
A pump assembly for generating and dispensing of particles of a solid material with or without dispensing of a fluid. The pump assembly preferably includes a fluid pump which in a cycle of operation draws the fluid through a fluid inlet and dispenses the fluid out a fluid outlet. The pump assembly carries a block of the solid material coalesced together and a rasp member, which during the cycle of operation, moves relative the rasp in engagement with the block whereby the rasp member disengages particles of the solid material from the block which particles drop under gravity downwardly adjacent the fluid outlet, for example, onto a user's hand as in the case that the fluid is a hand cleaning fluid and the solid is a solid soap.
