Cartridge for 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 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 alongside a liquid, using a mechanism that can be mechanically linked to the pump member for coordinated movement, 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 liquid dispensing is achieved, but solid particulate material cannot be generated or dispensed
Solution Approach 1:
The patent combines a liquid pump mechanism with a solid material dispensing mechanism into a single integrated pump assembly. The pump member simultaneously performs liquid pumping and, through mechanical linkage, drives the rasp member to dispense solid particulate material, thereby achieving dual functionality in one device.
Solution Approach 2:
The pump assembly is designed to perform multiple functions: pumping liquid through the fluid inlet and outlet, and generating/dispersing solid particulate material through the rasp member. The mechanically linked pump member and rasp member enable the single assembly to handle both liquid and solid materials, making it a universal dispensing device.
2Adaptability or versatility
If separate dispensing mechanisms are used for liquid and solid materials, then each material can be dispensed, but device complexity increases
Solution Approach 1:
Instead of using separate mechanisms for liquid and solid dispensing, the patent merges both functions into a single pump assembly. The pump member and rasp member are mechanically linked so that one actuation movement simultaneously drives both the liquid pump and the solid material dispenser, reducing overall device complexity while maintaining dual functionality.
Solution Approach 2:
The pump assembly serves as a universal device that handles both liquid and solid material dispensing through its multi-functional design. The single actuator drives both the pump member for liquid and the rasp member for solid material, eliminating the need for separate mechanisms and simplifying the overall system structure.
3Ease of operation
If the pump member and rasp member are mechanically linked, then coordinated movement is achieved, but device complexity increases
Solution Approach 1:
The pump member and rasp member are connected through a mechanical linkage that translates the pump member's movement into corresponding rasp member movement. This linkage enables coordinated dispensing of liquid and solid material with a single actuation, improving ease of operation despite the added mechanical connection.
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 efficient and concurrent dispensing of both liquid and solid materials, improving user experience and product usability by ensuring easy access to both components, such as hand soap and cleaner, without the need for separate dispensing mechanisms.
Implementation Method 1
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
Implementation Method 2
particles of the solid material from the block which 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.
