Solution Overview

Problem

Hot beverage preparation devices face challenges in providing an optimized lighting situation for both beverage preparation and maintenance activities, especially in unfavorable lighting conditions, and existing solutions are often complex, costly, and inefficient.

Innovation Solution

A hot beverage preparation device with a lighting unit integrated into the beverage outlet that illuminates both the dispensing area when closed and the maintenance area when open, utilizing LEDs and light guides for efficient and compact lighting, allowing for adjustable height and color options.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a lighting device is arranged to illuminate both the dispensing area and the maintenance area, then the lighting situation is optimized for beverage preparation, but the maintenance area becomes difficult to access in unfavorable lighting conditions

Engineering Contradiction:
Improvelighting situation for beverage preparationVSAvoidaccess to maintenance area
Core Design Contradiction:
Illumination intensityVSEase of operation

Solution Approach 1:

The lighting system is segmented into two independent lighting units: one for illuminating the dispensing area and another for illuminating the maintenance area. This allows each lighting unit to be independently controlled and positioned, resolving the contradiction by providing targeted illumination where needed without compromising access to either area.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The lighting system incorporates a door switch that dynamically controls the maintenance area lighting. When the door is opened to access the maintenance area, the lighting unit is automatically activated to illuminate the maintenance area, ensuring favorable lighting conditions are provided dynamically when needed without interfering with normal dispensing operations.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If the entire front is designed as a door to access the maintenance area, then the maintenance area is easily accessible, but the beverage outlet position becomes fixed and the visual appeal is reduced

Engineering Contradiction:
Improveaccess to maintenance areaVSAvoidhousing structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The front of the housing is segmented into two functional parts: a door portion that can be opened for maintenance access and a fixed portion that houses the beverage outlet. This segmentation allows the beverage outlet to remain in its optimal fixed position while still providing easy access to the maintenance area through the separable door section.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The door acts as an intermediary element between the user and the maintenance area. It provides a controlled access mechanism that allows maintenance personnel to reach the maintenance area without requiring the beverage outlet to be movable, thus maintaining both ease of operation and structural simplicity.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Illumination intensity

If separate light sources are provided for the maintenance area, then the lighting situation is optimized for both areas, but the device complexity and cost increase

Engineering Contradiction:
Improvelighting for maintenance areaVSAvoidlighting system structure
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The lighting system uses universal LED modules that can serve multiple functions. The same type of lighting unit is used for both the dispensing area and the maintenance area, allowing for standardized installation and control while providing optimized illumination for both functions without requiring completely separate lighting systems.

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

Solution Approach 2:

The lighting system incorporates a door switch that dynamically controls the maintenance area lighting. When the door is opened to access the maintenance area, the lighting unit is automatically activated to illuminate the maintenance area, ensuring favorable lighting conditions are provided dynamically when needed without interfering with normal dispensing operations.

Inventive Principle:
Principle #15Dynamics
