Solution Overview

Problem

Existing systems for preparing liquid products, such as beverages, face challenges in precisely controlling the preparation process under varying operating conditions and diverse product composition specifications, leading to inconsistencies in product quality and hygiene.

Innovation Solution

A system comprising a product preparation assembly with a concentrate holder, a valve member for regulating the flow of product concentrate, and a controller to automatically control the valve member's position, allowing for precise control of the ratio between concentrate and liquid flow, enabling user-adjustable product quality parameters, including foamed product firmness, through integration with a liquid injector and gas injector.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a conventional system without a movable valve member is used, then the device complexity is reduced, but the manufacturing precision of product composition and control precision under varying flow rates deteriorate

Engineering Contradiction:
Improveproduct composition controlVSAvoidvalve mechanism complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The valve member is made movable along the concentrate supply channel, transitioning from a static to a dynamic configuration. This allows the valve to adjust its position dynamically in response to varying water flow rates, maintaining precise control over concentrate flow and product composition under different operating conditions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The controller receives information about water flow rate variations and automatically adjusts the valve member position accordingly. This closed-loop feedback mechanism ensures that the concentrate-to-water ratio remains within specified ranges despite changes in operating conditions, achieving consistent product quality.

Inventive Principle:
Principle #23Feedback

2Productivity

If manual control of concentrate flow is used, then the device complexity is reduced, but the productivity and consistency of product preparation deteriorate

Engineering Contradiction:
Improveproduct preparation consistencyVSAvoidvalve control automation
Core Design Contradiction:
ProductivityVSExtent of automation

Solution Approach 1:

The system performs self-adjustment through automatic control. The controller automatically monitors water flow rate and adjusts the valve member position without requiring manual intervention, enabling the system to maintain optimal product composition and prepare multiple products consistently with high productivity.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Manual mechanical adjustment of the valve is replaced with an automated control system that uses sensors and actuators. This substitution enables precise, repeatable positioning of the valve member based on real-time flow rate measurements, ensuring consistent product preparation across multiple batches.

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

3Adaptability or versatility

If the valve member has limited positioning options, then the device complexity is reduced, but the adaptability to diverse product specifications deteriorates

Engineering Contradiction:
Improveproduct specification flexibilityVSAvoidvalve positioning mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The valve member can be positioned at multiple discrete locations along the concentrate supply channel, providing dynamic adjustment capability. This enables the system to adapt to diverse product specifications by selecting appropriate valve positions to achieve different concentrate flow rates and product compositions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the flow rate parameter by adjusting the valve member position. By moving the valve to different positions, the concentrate flow rate is varied to match different product requirements, achieving versatility in product specification while using a relatively simple positioning mechanism.

Inventive Principle:
Principle #35Parameter changes
