Solution Overview

Problem

Existing laundry dryers lack an efficient and convenient method for manually filling a liquid reservoir, which is essential for steam generation and treatment processes, often requiring complex modifications to accommodate the filling mechanism without compromising the dryer's design or user experience.

Innovation Solution

A laundry dryer design featuring a front frame with a panel window and liquid inlet port positioned at the upper front section, allowing for easy access to manually fill the liquid reservoir without significant modifications to other components, while maintaining the dryer's structural integrity and user-friendly interface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a liquid reservoir is added to the dryer for steam generation, then the dryer gains steam treatment functionality, but the device complexity increases due to additional components and installation requirements

Engineering Contradiction:
Improvesteam treatment functionalityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The front frame is designed to support multiple functions: it provides structural support for the dryer cabinet, serves as a mounting platform for the liquid reservoir and steam generator, and includes integrated pipe conduits for fluid transport. This multi-functionality reduces overall device complexity by combining several components into a single structural element.

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

Solution Approach 2:

The liquid reservoir system is designed as a separate, modular unit that can be independently installed and removed from the front frame. This segmentation allows the steam treatment functionality to be added without permanently modifying the entire dryer structure, reducing installation complexity.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the liquid reservoir is positioned in the upper front section, then ease of operation for manual filling is improved, but the available space for other components is reduced

Engineering Contradiction:
Improveease of fillingVSAvoidavailable space
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

The front frame utilizes the vertical dimension by positioning the liquid reservoir in the upper front section, allowing users to easily access the filling opening from above. This vertical arrangement optimizes the spatial distribution of components, providing ease of operation while maintaining adequate space for the steam generator and other elements in lower sections.

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

Solution Approach 2:

The liquid reservoir is integrated within the front frame structure, nesting it into the available space rather than adding external volume. The reservoir fits into the upper front section's internal cavity, maximizing space utilization while maintaining ease of access for filling operations.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Ease of operation

If the inlet port is positioned at the upper front section, then ease of operation for filling is improved, but manufacturing precision requirements increase to ensure proper alignment

Engineering Contradiction:
Improveaccessibility of inlet portVSAvoidalignment precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The inlet port is pre-positioned and integrated into the front frame during the frame's manufacturing process, ensuring proper alignment before the liquid reservoir is installed. This preliminary action eliminates the need for complex alignment procedures during assembly, reducing manufacturing precision requirements while maintaining ease of operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The inlet port is merged with the front frame structure, creating a single integrated component rather than separate parts requiring alignment. This merging ensures that the inlet port's position is inherently aligned with the frame's structural features, reducing manufacturing precision requirements while providing excellent accessibility for filling operations.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The invention relates to a laundry dryer comprising: a front frame (30) extending from a base region to an upper region at the front region of the dryer; a laundry storing compartment adapted to receive laundry to be treated; a front wall (8) of the dryer which is at least partially supported by the front frame (30) and comprises a loading opening for loading laundry into the laundry storing compartment; an upper front panel (12) of the dryer which is at least partially supported by the front frame (30); a laundry treatment unit adapted to provide an agent for the laundry in the laundry storing compartment for treating the laundry; a liquid reservoir fluidly connected to the laundry treatment unit for supplying liquid thereto; and a liquid inlet port adapted for manually filling the liquid reservoir with liquid and which is arranged at an upper front section of the dryer. According to the invention, the upper front panel (12) has a panel window (44, 46) which provides an access opening for servicing or for exclusively servicing the liquid reservoir and which is arranged at a position such that the panel window (44, 46) exposes the inlet port for filling the liquid to the inlet port through the panel window.
