Solution Overview

Problem

Existing solutions for aligning the decorative front panel of integrated appliances, such as dishwashers, with adjacent furniture panels are cumbersome and require manual handling, making the installation process laborious and often requiring assistance, especially in limited spaces like kitchen corners.

Innovation Solution

A coupling system for the dishwasher that includes a support member, a sliding member, and a regulation group with a rotatable screw, allowing for easy sliding and adjustment of the decorative front panel without manual lifting, using a snap-fit mechanism for panel pins and a U-shaped support member for secure alignment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If manual lifting and hand-holding methods are used to align the decorative front panel, then the panel can be positioned, but the installation process becomes laborious and time-consuming

Engineering Contradiction:
Improvealignment precisionVSAvoidinstallation time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent applies preliminary action by providing adjustment mechanisms that allow the decorative front panel to be pre-positioned and adjusted before final fixation. The panel can be slidably moved along the door panel using the adjustment mechanisms to achieve proper alignment with furniture panels, and this adjusted position is then maintained during screwing operations, eliminating the need for continuous manual holding throughout the installation process.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If manual lifting and hand-holding methods are used to align the decorative front panel, then the panel can be positioned, but the installation process requires assistance from multiple operators

Engineering Contradiction:
Improvealignment precisionVSAvoidinstallation ease
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The patent applies self-service by designing adjustment mechanisms that enable a single operator to independently adjust and position the decorative front panel without requiring assistance from other operators. The mechanisms allow one person to slide the panel into position, make alignment adjustments, and secure it to the door panel autonomously, significantly improving installation ease.

Inventive Principle:
Principle #25Self-service

3Area of stationary object

If the dishwasher is installed in a corner with limited space, then space utilization is improved, but the freedom of movement for operators is restricted

Engineering Contradiction:
Improvekitchen space utilizationVSAvoidoperator mobility
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The patent applies dimensionality change by providing adjustment mechanisms that allow the decorative front panel to be positioned and aligned along multiple dimensions (vertical and horizontal sliding directions) without requiring operators to physically maneuver around the appliance. The mechanisms translate rotational movements of adjustment elements into precise positional adjustments of the panel, enabling accurate alignment even when operator access is limited by corner installation constraints.

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

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Facilitates fast and easy installation and regulation of the decorative front panel, eliminating the need for manual handling and assistance, and is suitable for installation in tight spaces like kitchen corners.

Implementation Method 1

a sliding member (210) coupled to the decorative front panel (140) and slidably coupled to the support member (205) for sliding with respect and parallel thereto

Methodology Applied
Scientific EffectFriction: Friction

Implementation Method 2

a regulation group (215) comprising a rotatable regulation member (219) and a conversion member (217) coupled to the regulation member (219) and to the sliding member (210) for converting a rotation of the regulation member (219) into said sliding of the sliding member (210)

Methodology Applied
Scientific EffectScrew mechanism: Screw

Implementation Method 3

the sliding member (210) comprises an engaging element (210SF) for engaging a respective panel pin (145) of the decorative front panel (140), wherein the engaging element (210SF) is a snap-fit element for the snap-fit engagement of said panel pin (145)

Methodology Applied
Scientific EffectElasticity: Elasticity
