Modular Door Lint Filter Seat for Laundry Dryer Functional Variation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high development and production costs of different filter and cleaning variants in laundry drying devices make it challenging to create simplified and cost-effective designs for these appliances.
Innovation Solution
A modular manufacturing method for laundry drying appliances, where interchangeable elements with standardized mechanical interfaces are inserted into specific seats, allowing for various filter and cleaning configurations without adapting the seat, enabling a constant basic machine construction and easy variation of device functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different filter and cleaning variants are developed for laundry drying devices, then functional versatility is improved, but development and production costs increase
Solution Approach 1:
The patent implements a universal seat structure that can accommodate multiple different filter elements and cleaning device variants. The standardized mechanical interfaces (mounting holes, sealing surfaces, guide elements) allow various functional components to be installed in the same seat location, enabling one basic machine construction to support multiple functional configurations without requiring separate development for each variant.
Solution Approach 2:
The patent divides the laundry drying device into modular components: a constant basic machine construction (the seat) and interchangeable functional elements (filters and cleaning devices). This segmentation allows the functional variants to be developed as separate, standalone components that can be independently manufactured and then assembled into the same basic structure, reducing overall development and production costs.
2Adaptability or versatility
If multiple filter and cleaning variants are created, then device functionality is improved, but development effort increases
Solution Approach 1:
The standardized seat design serves as a universal platform that simplifies the overall system design. By creating one adaptable seat structure with standardized interfaces, the patent reduces the complexity that would otherwise arise from designing multiple unique mounting structures for each filter and cleaning device variant. The constant basic machine construction provides design consistency across all variants.
Solution Approach 2:
By separating the constant basic machine construction from the variable functional elements, the patent reduces design complexity. Each filter and cleaning device variant can be designed independently with focus on its specific function, while the seat provides a standardized interface that simplifies integration. This modular approach makes the overall system more manageable than designing entirely different structures for each variant.
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
This approach simplifies the design and production of laundry drying devices, reducing development effort and enabling functional variation with minimal new component development, resulting in cost-effective and user-friendly appliances.
Implementation Method 1
Water vapor in the process air arriving there - which previously flowed out of a laundry drum as moist process air - condenses on the cool surface of the first heat exchanger
Implementation Method 2
Fluff, hair, etc. can be partially held back by the door fluff filter immediately after exiting the laundry drum
Implementation Method 3
a cleaning device is assigned to it, by means of which pressurized water can be applied to the fluff filter in order to clean it
