Solution Overview

Problem

Conventional beverage makers have a bulky, one-piece drip tray and cladding element assembly that prevents dishwasher cleaning, leading to increased manual cleaning efforts and potential damage from aggressive cleaning agents.

Innovation Solution

A detachable auxiliary frame connects the drip tray and cladding element, allowing for easy separation and reassembly, with a magnetic or screw connection for stability and ease of use, and a sensor device for ensuring correct assembly and safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the drip tray and cladding element are designed as a one-piece component, then the structural stability and aesthetic appearance are improved, but the cleaning capability in dishwasher is lost

Engineering Contradiction:
Improvestructural stabilityVSAvoidcleaning capability
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The invention divides the one-piece assembly into separate components: the drip tray (2) and the cladding element (3) can be detached from each other. This segmentation allows the drip tray to be removed for dishwasher cleaning while the cladding element remains on the appliance, resolving the contradiction between structural stability and cleaning capability.

Inventive Principle:
Principle #1Segmentation

2Shape

If the cladding element has a painted surface for aesthetic reasons, then the appearance quality is improved, but the resistance to aggressive cleaning agents is lost

Engineering Contradiction:
Improveaesthetic appearanceVSAvoiddamage from cleaning agents
Core Design Contradiction:
ShapeVSObject-affected harmful factors

Solution Approach 1:

By separating the cladding element with the painted surface from the drip tray, the invention allows the painted surface to remain intact on the appliance while the drip tray (which gets dirty) can be removed for cleaning. This eliminates the need to expose the painted surface to aggressive dishwasher cleaning agents.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention extracts the drip tray function from the cladding element, allowing the drip tray to be removed and cleaned separately. This extraction protects the aesthetically important cladding element from direct contact with aggressive cleaning agents while still enabling thorough cleaning of the contaminated drip tray.

Inventive Principle:
Principle #2Taking out (Extraction)

3Volume of moving object

If the drip tray protrudes considerably into the interior for adequate volume, then the liquid residue collection capacity is improved, but the aesthetic appearance is worsened

Engineering Contradiction:
Improveliquid residue collection capacityVSAvoidaesthetic appearance
Core Design Contradiction:
Volume of moving objectVSShape

Solution Approach 1:

The invention segments the functional drip tray from the aesthetic cladding element. The drip tray can be designed with adequate volume and protrusion for functional purposes, while the cladding element provides the aesthetic finish. When the drip tray is removed for cleaning, the cladding element remains in place maintaining the appliance's appearance.

Inventive Principle:
Principle #1Segmentation
