Solution Overview

Problem

Existing beverage preparation machines face challenges with space utilization and component arrangement due to flexible cover members that are difficult to guide and occupy internal space, making it hard to implement other components and ensuring user safety.

Innovation Solution

A beverage preparation machine design featuring a cover member with movable plates and a panel that form pull-out flaps, allowing the cover member to occupy minimal space and prevent user access, with a drive element for automatic movement and gravity-assisted return, ensuring reliable translation guidance and ergonomic implementation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a flexible strip cover member is used to cover the opening, then user safety is improved by preventing finger insertion, but the cover member occupies significant internal space and is difficult to guide during movement

Engineering Contradiction:
Improveuser safetyVSAvoidspace utilization
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The cover member is segmented into a panel and at least one first plate that can move independently. The first plate is movable vertically relative to the frame and panel, allowing it to be positioned in a deployed state for safety coverage or a storage state for compact space utilization, eliminating the need for a long flexible strip to continuously cover the opening during head movement.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cover member transitions from a static flexible strip to a dynamic segmented structure where the first plate can change position between deployed and storage states. This dynamic reconfiguration allows the cover member to adapt its shape and position based on operational requirements, improving both safety coverage and space efficiency.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the dispensing head moves between high standby position and low working position, then beverage dispensing functionality is improved, but the flexible strip cover member becomes difficult to guide and occupies excessive space

Engineering Contradiction:
Improvedispensing functionalityVSAvoidcover member guidance
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cover member is divided into a panel attached to the dispensing head and a separate movable first plate. This segmentation allows the panel to move with the dispensing head while the first plate independently adjusts its position, eliminating the guidance difficulties associated with a continuous flexible strip and reducing the space occupied during head movement between positions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The first plate is designed to move in a vertical dimension relative to the frame and panel, adding a degree of freedom to the cover member system. This vertical movement capability allows the cover member to accommodate the dispensing head's movement between high and low positions without requiring complex lateral guidance mechanisms.

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

3Device complexity

If the cover member is arranged directly behind the opening with minimal footprint, then space efficiency is improved, but the cover member must still effectively prevent user access to the opening

Engineering Contradiction:
Improvespace efficiencyVSAvoiduser access prevention
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The first plate can dynamically transition between a deployed position where it extends beyond the panel to provide extensive coverage and prevent user access, and a storage position where it retracts to occupy minimal space. This dynamic adjustment allows the cover member to maximize safety coverage when needed while maintaining space efficiency during normal operation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The first plate is positioned in advance in a deployed state to cover the opening before user interaction occurs, providing proactive safety protection. The plate can be pre-positioned to mask the opening over a height of 2H when the dispensing head is in the low position, preventing potential finger insertion before it becomes a hazard.

Inventive Principle:
