Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing condensation washer-dryer designs face challenges in sealing process air guidance, mechanical stability, and efficient production and assembly, particularly due to the need for multiple components and additional sealants in the bottom assembly.
Innovation Solution
A supporting structure comprising a single-piece base module and a permanently welded process air cover eliminates the need for sealants, enhancing mechanical rigidity and sealing efficiency by forming a unified air guidance component that connects the condenser housing, process air fan, and heating duct.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple single components are used to form the bottom assembly, then the device can be manufactured in modular parts, but additional sealants are required at the joints which compromises sealing reliability
Solution Approach 1:
The patent merges multiple separate components (base module, rear wall, air guidance ducts, condenser housing, fan housing) into a single integrated bottom assembly that is injection-molded as one piece. This eliminates the need for additional sealants at joints while maintaining modular manufacturing benefits, directly resolving the contradiction between ease of manufacture and sealing reliability.
2Reliability
If additional sealants are provided at joints, then sealing can be achieved, but the device complexity and assembly steps increase
Solution Approach 1:
By integrating all air guidance components, housing elements, and functional parts into a single injection-molded bottom assembly, the patent eliminates multiple joints that would require sealants. This reduces both the sealing complexity and overall device complexity, while maintaining reliable sealing through the integrated design.
3Ease of manufacture
If the bottom assembly is manufactured in several single components, then production flexibility is improved, but mechanical stability and rigidity are reduced
Solution Approach 1:
The patent combines multiple structural components into a single injection-molded bottom assembly with integrated ribs and reinforcement structures. This unified construction provides superior mechanical rigidity and stability compared to assembled components, while the injection molding process itself offers production flexibility through automated manufacturing.
4Reliability
If sealant is used at the process air duct joints, then sealing can be achieved, but the manufacturing precision requirements are reduced
Solution Approach 1:
By integrating the process air ducts directly into the bottom assembly through injection molding, the patent eliminates separate joints that would require sealants. This integrated design necessitates high manufacturing precision within the single molding process, ensuring proper sealing and air guidance without relying on additional sealing materials.

AI summary
A condensation washer-dryer, in particular, the air-guiding process. The base module is used to receive function parts and components of the air guide and is closed on the rear side by means of a process air cover and forms a plastic, stable support structure for the washer-dryer. The connecting surfaces are large and extend, preferably, over the entire width of the washer-dryer. Due to said embodiment, air guiding channels are formed in a simple manner on the rear side of the base module and the housing of the process air ventilator is closed on the rear side. Sealing elements are no longer required due to said welding of said type of connection and an exceptionally high mechanical rigidity is obtained.
