Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid dispenser assemblies face challenges in easy cleaning, accuracy, and repeatability, particularly when dispensing viscous liquids like adhesives, which can solidify during delays, leading to operational inefficiencies.
Innovation Solution
A liquid dispenser design featuring a removably secured liquid flow path assembly with a latch system and displacement assembly, allowing for easy disassembly and cleaning, along with an oblique fluid path to enhance liquid flow and accuracy, including a valve stem guided by a valve guide and a securing member for secure mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the liquid flow path assembly is made removable with latch assembly, then ease of cleaning is improved, but device complexity increases
Solution Approach 1:
The liquid flow path assembly is divided into separable components that can be easily detached from the mount using the latch assembly. This segmentation allows the flow path assembly to be removed for cleaning or replacement while maintaining a relatively simple overall structure through modular design.
Solution Approach 2:
The liquid flow path assembly is designed as a disposable or easily replaceable component. The latch assembly enables quick removal of the flow path assembly without requiring complex disassembly procedures, aligning with the principle of using simple, replaceable parts that can be quickly discarded or cleaned.
2Ease of repair
If the liquid flow path assembly is made removable, then ease of cleaning is improved, but reliability may worsen due to potential leakage at connection points
Solution Approach 1:
The latch assembly is designed to completely separate the liquid flow path assembly from the mount when needed, allowing full removal without leaving residual connections that could cause leakage. This extraction approach ensures that when the assembly is reattached, the connection points are clean and properly sealed, maintaining reliability.
Solution Approach 2:
The latch assembly is pre-configured with engagement features that ensure proper alignment and sealing before the liquid flow path assembly is fully attached to the mount. This preliminary positioning action prevents misalignment and ensures reliable sealing at the connection points, addressing potential leakage issues before they occur.
3Manufacturing precision
If displacement assembly is added to control detachable portions, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The displacement assembly introduces dynamic control to the mounting mechanism, allowing the detachable portions to be precisely positioned and secured during assembly. This dynamic adjustment capability enables manufacturing precision to be achieved without requiring overly complex fixed-positioning mechanisms.
Solution Approach 2:
The displacement assembly is designed to self-regulate the positioning of the detachable portions through its own mechanical features. The assembly automatically achieves proper alignment and securing without requiring external precision tools or complex control systems, thereby improving manufacturing precision while minimizing added complexity.

AI summary
One general aspect includes a liquid dispenser with a mount having a mount aperture. A liquid flow path assembly is removably secured to the mount and has an inlet configured to receive liquid, an outlet configured to dispense liquid and a passageway fluidly coupling the inlet to the outlet. A third aperture apart from the inlet and the outlet is fluidly coupled to the passageway and forming a valve guide. The liquid flow path assembly is disposed on the mount to align the third aperture with the mount aperture. An elongated valve has a valve stem guided by the valve guide and extends through the third aperture and the mount aperture. A latch assembly secures the liquid flow path assembly to the mount.
