Kitchen appliance system and a method for automatically taring a kitchen appliance system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional kitchen appliances require multiple manual taring operations when ingredients are added or accessories are changed, leading to user inconvenience and potential weight reading distortions.
Innovation Solution
A kitchen appliance system with a detection device to identify accessory features and a control device to automatically calculate net weight by detecting position changes, eliminating the need for manual taring and accurately determining net weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual taring operations are performed multiple times when ingredients are added or accessories are changed, then weight readings can be adjusted, but user convenience deteriorates and operation complexity increases
Solution Approach 1:
The system automatically performs taring operations by detecting accessory identification features and position changes, eliminating the need for manual user input. The control device autonomously calculates net weight by subtracting accessory weights from gross weight readings, making the system self-servicing in the taring process.
Solution Approach 2:
The system uses detection devices to identify accessory features and monitor position changes, then feeds this information back to the control device which automatically adjusts weight calculations. This closed-loop feedback mechanism ensures accurate net weight determination without requiring user intervention.
2Measurement precision
If manual taring is performed repeatedly, then weight measurements can be maintained, but time consumption increases
Solution Approach 1:
The system performs preliminary identification of accessory features when accessories are first attached to the base unit. The control device stores this identification information and uses it for subsequent automatic taring operations, eliminating the need for repeated manual taring and reducing time loss.
Solution Approach 2:
The detection device continuously monitors accessory position changes and the weighing module continuously provides gross weight readings. The control device continuously calculates net weight based on this continuous data stream, ensuring uninterrupted accurate measurement without periodic manual intervention.
3Device complexity
If accessory weights are not automatically accounted for, then device complexity is reduced, but measurement accuracy deteriorates due to weight reading distortions
Solution Approach 1:
The detection device serves multiple functions: it identifies accessory types, determines accessory weights from stored data, and detects position changes. This multi-functional approach maintains relatively simple device structure while achieving accurate net weight measurement through automatic accessory weight compensation.

AI summary
The invention relates to a kitchen appliance system (2, 202) comprising a basic unit (4, 204) having a housing (14, 214) and at least one accessory (6, 8, 206, 208) having an identification feature. A weighing module (16, 220) designed to detect a gross weight and a control unit (18, 216) are provided on the basic unit (4, 204).Furthermore, the base unit (4, 204) is equipped with a detection device (22, 218) for capturing an identification feature of at least one accessory (6, 8, 206, 208), and the control unit (18, 216) is configured to detect a change in position of the at least one accessory (6, 8, 206, 208) relative to the base unit (4, 204), to retrieve weight information corresponding to an identification feature captured by the detection device (22, 218), and to calculate a net weight based on a gross weight captured by the weighing module (16, 220) and taking the weight information into account. A corresponding procedure is also described.
