Solution Overview

Problem

Traditional hot beverage manifolds are costly to produce, prone to leaks and failures, and have inefficient drain and cleaning processes, leading to high maintenance costs and downtime.

Innovation Solution

A lightweight, molded manifold assembly with integrated solenoid valves, vent valves, and a flow regulator, along with a controller and memory for efficient operation, reduces leak paths and enhances drain and vent performance, incorporating a top vent valve for complete venting and a lower manifold clean out port for efficient service and descaling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If traditional machined manifolds are used, then manufacturing precision and reliability are maintained, but production cost and manufacturing time increase

Engineering Contradiction:
Improveproduction costVSAvoidmanifold precision
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent combines multiple separate components (manifold body, solenoid valves, flow regulators, vent valves, drain ports) into a single integrated molded assembly. This merging reduces the number of separate manufacturing operations and assembly steps, lowering production cost while maintaining functional precision through the molded integration of fluid pathways and control elements.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent replaces traditional mechanical machining processes with molded manufacturing for the manifold assembly. This substitution eliminates time-consuming machining operations while achieving the required geometric precision and surface finishes through molding techniques, thereby reducing both manufacturing time and cost.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If multiple separate assemblies including in-line vent valves and flow regulators are used, then flow control functionality is achieved, but leak risk and assembly complexity increase

Engineering Contradiction:
Improveflow control capabilityVSAvoidleak resistance
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent integrates solenoid valves, flow regulators, and vent valves directly into the manifold body through molded connections. This eliminates multiple separate assemblies and their associated connection points, thereby reducing leak paths and improving reliability while maintaining full flow control functionality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The manifold assembly serves multiple functions simultaneously: fluid distribution, flow regulation, venting, and draining, all integrated into a single component. This multi-functionality reduces the number of separate assemblies needed while maintaining comprehensive control capabilities.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If traditional drain capability is used, then basic draining function is provided, but drainage efficiency is insufficient causing freezing damage risk

Engineering Contradiction:
Improvedrain functionVSAvoidfreezing protection
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent divides the draining function into multiple separate drain ports positioned at different locations within the manifold assembly. This segmentation enables more effective drainage by providing multiple exit paths for fluid removal, ensuring complete evacuation and preventing freezing damage in all sections of the manifold.

Inventive Principle:
Principle #1Segmentation

4Ease of repair

If traditional clean out and descaling procedures are used, then maintenance is possible, but additional downtime and operational cost increase

Engineering Contradiction:
Improvemaintenance capabilityVSAvoiddowntime
Core Design Contradiction:
Ease of repairVSLoss of time

Solution Approach 1:

The patent incorporates a dedicated cleanout port as a separate accessible feature on the manifold assembly. This segmentation allows maintenance personnel to access and clean specific areas of the manifold without disassembling the entire system, significantly reducing maintenance downtime and operational disruption.

Inventive Principle:
Principle #1Segmentation

AI summary

A hot beverage maker manifold assembly is disclosed integrating components into the manifold body minimizing leak paths and creating efficient overall drain and vent performance of the aircraft hot beverage maker. A top vent valve (122) is integrated into the manifold body (110) for complete venting and draining performance in the manifold assembly as well as in an associated hot water tank (150) and tank lines (158). An incorporated flow regulator (256) housing within the manifold body at a tea line exit fitting limits the number of downstream leak paths and complexity. An integrated lower manifold clean out port allows for efficient bidirectional service of the manifold and efficient descaling and flushing.
