Solution Overview
Problem
Existing household appliances lack flexibility and efficient accessory management, particularly in terms of heat transfer and usability, leading to reduced accessory lifespan and complex handling.
Innovation Solution
A household appliance design featuring a secondary receiving area that is distinct from the main usable space, allowing for manual removal and placement of accessories without tools, with features like a lowering mechanism, sensor means, and wireless signal transmission, ensuring ergonomic and safe storage while minimizing heat transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the accessory is stored in a door unit, then the device structure is compact, but the accessory is exposed to high heat transfer during cooking processes reducing its service life
Solution Approach 1:
The accessory is extracted from the door unit storage location and placed in the secondary receiving area formed by the household appliance base body unit. This separation removes the accessory from the high-heat door unit environment during cooking operations, reducing thermal exposure and extending service life while maintaining integrated storage capability
2Reliability
If the accessory is integrated into the household appliance base body unit, then heat transfer to the accessory is reduced, but the device complexity increases
Solution Approach 1:
The household appliance base body unit is designed with multi-functionality, serving both as the primary cooking appliance structure and as the provider of the secondary receiving area for accessory storage. This eliminates the need for separate dedicated storage structures, reducing overall device complexity while achieving reduced heat transfer to the accessory
3Duration of action of stationary object
If the secondary receiving area is provided by a door unit, then the main usable space is maximized, but the accessory handling becomes less ergonomic
Solution Approach 1:
The secondary receiving area is positioned in a different spatial dimension relative to the main usable space - specifically arranged above or laterally next to it rather than within the door unit. This dimensional repositioning maintains maximum main usable space while dramatically improving accessory handling ergonomics through convenient access positions
4Ease of operation
If the accessory is stored in a location close to the main usable space, then access is convenient, but the accessory is exposed to more heat and damaging influences
Solution Approach 1:
The secondary receiving area is designed with local quality characteristics that differ from the main usable space - specifically positioned in a location (above or lateral to main space) that provides convenient access while being thermally isolated from the high-heat cooking environment. This creates an optimal local zone for accessory storage with both good accessibility and reduced thermal exposure

AI summary
The invention is based on a domestic appliance device with at least one domestic appliance body unit (10; 10a - 10d), at least one secondary receiving area (12; 12a - 12d) and at least one accessory part (14; 14a; 14b), which in at least one operating state is at least partially in the Auxiliary recording area (12; 12a-12d) is arranged and which is provided for manual removal from the auxiliary recording area (12; 12a-12d) by a user. In order to achieve a long-lasting construction, it is proposed that the domestic appliance body unit (10; 10a - 10d) at least partially forms the secondary receiving area (12; 12a - 12d).
