Solution Overview

Problem

The production of dishwashing machines equipped with auxiliary functional systems, such as condensation drying or liquid-storage systems, requires different component assemblies, leading to increased complexity and costs due to distinct structural configurations.

Innovation Solution

A dishwashing machine design with a basic structure that allows for the convenient and precise assembly of auxiliary components like condensation devices or storage tanks, where the same basic structure can be used for both systems, simplifying production and assembly by utilizing a common base and tub configuration with adaptable mounting mechanisms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If different component assemblies are used for condensation drying systems and liquid-storage systems, then each system can be optimized for its specific function, but the production complexity and costs increase due to distinct structural configurations

Engineering Contradiction:
Improvefunctional optimizationVSAvoidproduction complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies universality by designing a common base structure that can accommodate both condensation drying systems and liquid-storage systems. The base (element 2) and tub (element 3) form a standardized platform that supports different auxiliary functional systems through adaptable mounting mechanisms, allowing the same basic structure to serve multiple functions depending on which auxiliary system is installed.

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

Solution Approach 2:

The patent implements dynamics through adaptable mounting mechanisms that allow the auxiliary functional system to be selectively positioned and configured. The mounting structure can adjust to accommodate different system types (condensation device or storage tank) while maintaining proper positioning and functionality, enabling the base structure to dynamically adapt to different functional requirements.

Inventive Principle:
Principle #15Dynamics

2Reliability

If different component assemblies are used for condensation drying systems and liquid-storage systems, then each system can be optimized for its specific function, but manufacturing costs increase due to distinct structural configurations

Engineering Contradiction:
Improvefunctional optimizationVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent reduces manufacturing costs by eliminating the need to produce separate base structures for different auxiliary systems. The universal base (element 2) and tub (element 3) configuration can be manufactured once and used for both condensation drying and liquid-storage applications, reducing tooling, tooling setup, and production line complexity while maintaining functional optimization through selective auxiliary system installation.

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

3Device complexity

If a standardized basic structure is used for both condensation drying and liquid-storage systems, then production is simplified and costs are reduced, but the ability to optimize each system's specific functional requirements may be compromised

Engineering Contradiction:
Improveproduction simplicityVSAvoidfunctional optimization
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent applies segmentation by separating the machine into a standardized base structure (elements 2 and 3) and interchangeable auxiliary functional systems. This allows the common platform to be optimized for general requirements while the modular auxiliary systems can be independently designed and optimized for their specific functions, whether condensation drying or liquid storage.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The adaptable mounting mechanisms provide dynamic positioning capabilities that allow the auxiliary systems to be precisely positioned according to their specific functional requirements. This ensures that even with a standardized base, each auxiliary system can be optimized for its function through adjustable mounting configurations.

Inventive Principle:
Principle #15Dynamics

AI summary

A dishwashing machine has a structure that comprises a base (2) and a wash tub (3) supported by the base (2). The machine (1) has an auxiliary functional system, such as a system for drying dishes or a liquid-storage system, which comprises a hollow body (31) with a first portion (34) that is generally vertical and faces a stationary side wall (3d) of the tub (3). The hollow body (31) has a second portion (35) that is generally horizontal and faces the upper wall (3b) of the tub (3), in which a first opening is defined. The upper wall (3b) of the tub (3) has a through opening to which the first opening of the hollow body (31) is operatively coupled, the second portion (35) of said body (31, 31') being secured to the upper wall (3b) of the tub (3) at the aforesaid through opening.
