Solution Overview

Problem

Conventional on-demand beverage machines using compressed powder tablets face challenges in achieving rapid and even dissolution, often resulting in incomplete dissolution and a weak beverage due to inefficient energy distribution from single or multiple water jets.

Innovation Solution

A machine design featuring a spindle-mounted compressed disc of ingredients within the brew chamber, where a high-energy water jet impinges on the peripheral edge to rotate and disintegrate the disc, ensuring rapid and even dissolution with focused energy distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If a single water jet is used to dissolve the tablet, then the energy consumption is low, but the dissolution is uneven and incomplete

Engineering Contradiction:
Improveenergy consumptionVSAvoiddissolution uniformity
Core Design Contradiction:
Loss of energyVSManufacturing precision

Solution Approach 1:

The single water jet system is segmented into multiple jets arranged in a circular pattern. This segmentation allows the energy to be distributed across multiple impact points on the tablet surface, achieving both energy efficiency and uniform dissolution. The multiple jets work simultaneously to break up the tablet from different locations, ensuring complete and even dissolution without concentrating all energy in one spot.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system transitions from a single-point jet impact to a distributed circular arrangement of jets. By adding the spatial dimension of circular distribution, the system achieves broader coverage of the tablet surface while maintaining the energy efficiency of individual jets. This dimensional change allows simultaneous multi-point contact with the tablet, resolving the contradiction between energy use and dissolution uniformity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Manufacturing precision

If multiple water jets are used to improve dissolution coverage, then the dissolution uniformity improves, but the energy consumption and pressure requirements increase proportionately

Engineering Contradiction:
Improvedissolution uniformityVSAvoidenergy consumption
Core Design Contradiction:
Manufacturing precisionVSLoss of energy

Solution Approach 1:

The multiple jets are segmented and arranged in a circular pattern, allowing each jet to operate at lower individual pressure while collectively achieving comprehensive coverage. This segmentation enables the system to distribute the total energy requirement across multiple lower-power jets, maintaining dissolution uniformity without proportionally increasing overall energy consumption.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The circular arrangement of jets provides multi-functionality by simultaneously achieving coverage of the entire tablet surface while maintaining energy efficiency. Each jet in the circular array contributes to both the uniformity of dissolution and the overall energy management, making the system universally effective for tablets of various sizes without requiring proportional increases in pressure or energy input.

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

3Productivity

If the jet velocity is increased to dissolve the tablet faster, then the dissolution speed improves, but the energy consumption increases and the jet must be moved to achieve even dissolution

Engineering Contradiction:
Improvedissolution speedVSAvoidenergy consumption
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The high-velocity jet concept is segmented into multiple lower-velocity jets arranged circularly. This segmentation achieves rapid dissolution through parallel action of multiple jets rather than relying on a single high-velocity jet that would consume excessive energy. The combined effect of multiple jets acting simultaneously provides both speed and energy efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The circular arrangement of jets provides continuous useful action across the entire tablet surface from the moment contact begins. Unlike a single moving jet that requires relocation to achieve even dissolution, the circular array of stationary jets simultaneously acts on multiple points, ensuring continuous and uniform dissolution throughout the tablet without energy-wasting movement or relocation.

Inventive Principle:
Principle #20Continuity of useful action
