Solution Overview

Problem

Existing liquid food or beverage machines lack sufficient ergonomics and user-friendliness in communicating machine conditions to the user, requiring users to physically inspect the machine to understand status messages, leading to frustration and stress.

Innovation Solution

A liquid food or beverage machine with an illuminatable outer face that extends across a substantial part of the machine's face, using light emission to visually indicate machine conditions such as water level, ingredient availability, or pre-heating status, allowing users to recognize conditions from a distance and reducing the need for close inspection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a small display or indicator lamp is used to show machine conditions, then the device complexity is reduced, but the ease of operation deteriorates because users must physically inspect the machine to understand status messages

Engineering Contradiction:
Improveuser-friendliness in communicating machine conditionsVSAvoidsize of illuminatable outer face
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent transitions from traditional small point-based indicators (0D/1D) to a large-area illuminatable face (2D) that extends across a substantial part of the machine's outer face. This dimensional expansion allows status information to be communicated over a much larger visual area, enabling users to recognize machine conditions from a distance without physical inspection, thereby resolving the contradiction between ease of operation and device complexity.

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

Solution Approach 2:

The patent employs different colors of light (e.g., red, yellow, green) to indicate different machine conditions such as water level, ingredient availability, and pre-heating status. This color-coding system allows multiple pieces of information to be communicated simultaneously across the large illuminatable area, maintaining visual simplicity while conveying comprehensive status information, thus improving ease of operation without proportionally increasing device complexity.

Inventive Principle:
Principle #32Color changes

2Loss of information

If traditional indicator lamps or small displays are used, then the manufacturing cost is lower, but the loss of information increases because users cannot recognize conditions from a distance

Engineering Contradiction:
Improvevisibility of machine conditionsVSAvoidmanufacturing complexity of illuminatable face
Core Design Contradiction:
Loss of informationVSEase of manufacture

Solution Approach 1:

The patent uses a large-area illuminatable face that spans a substantial portion of the machine's outer face, transforming information communication from a localized point indicator to an extended surface display. This dimensional approach ensures that status information is visible from a distance and captures the user's attention immediately, significantly reducing information loss while the modular design keeps manufacturing complexity manageable.

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

Solution Approach 2:

The large illuminatable outer face serves multiple functions simultaneously: it displays different machine conditions, communicates status information, and provides visual feedback across various operational states. This multi-functionality consolidates what would otherwise require multiple separate indicators into a single universal display surface, reducing the overall number of components and simplifying manufacturing while improving information visibility.

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

3Productivity

If users must physically inspect the machine to understand status messages, then the device complexity is reduced, but the productivity deteriorates due to user frustration and stress

Engineering Contradiction:
Improveuser efficiency in addressing machine conditionsVSAvoidstructure of warning device
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent enables users to recognize machine conditions (such as low water level, full receptacle, or pre-heating status) from a distance before approaching the machine. This preliminary visual recognition allows users to mentally prepare and address issues proactively, eliminating the frustration of discovering problems only upon physical inspection, thereby improving productivity without requiring complex internal structures.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The large illuminatable face provides immediate and unambiguous visual feedback about machine conditions, creating a clear communication loop between the machine and user. This enhanced feedback mechanism eliminates ambiguity and reduces the cognitive load on users, allowing them to quickly understand and respond to machine status, thus improving productivity while maintaining a relatively simple device structure.

Inventive Principle:
Principle #23Feedback

AI summary

A machine (1) for preparing a liquid food or beverage comprising: at least one outermost machine face selected from a front face (12), a top face and a lateral face (7); a means for emitting light (22) having at least one state of light emission and a state of light non emission and further having an illuminatable outer face (81, 101', 121) on said at least one outermost machine face (12), the illuminatable outer face (81, 101', 121) being arranged to be illuminated when in said state of light emission; and a control unit (20) connected to the light means. The control unit is arranged to detect at least one condition of such machine, in particular a condition involving a non immediate readiness of such machine to prepare a liquid food or beverage, and communicate said condition to a user via said illuminatable outer face (81, 101', 121) by changing the state of the light means (22). This illuminatable outer face (81, 101', 121) extends in at least one direction across a substantial part of the outermost machine face (12). Moreover, the illuminatable outer face (81, 101', 121) is arranged to be substantially entirely illuminated when in this state of light emission.
