Solution Overview

Problem

Existing electrical kitchen appliances lack an operating unit that can be operated independently of the appliance, limiting user flexibility and safety, especially in situations requiring remote control or reduced functionality.

Innovation Solution

An operating unit that can be detachably attached to the appliance, switching between two operating modes: one for direct attachment with a full range of functions and another for remote operation with a reduced range, using wired and wireless data transmission to facilitate safe and convenient control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the operating unit is detachably attached to the appliance, then user flexibility and convenience are improved, but device complexity increases

Engineering Contradiction:
Improveuser flexibilityVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The operating unit is separated from the main appliance body as a detachable component. This segmentation allows the control unit to be independently attached or removed, providing users with flexibility to position the control where needed while simplifying the main appliance structure when the control unit is not in use.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The detachable operating unit serves multiple functions: it can be attached to the appliance for direct control, removed for remote operation, and potentially used with different appliance configurations. This multi-functionality justifies the added complexity by providing versatile operational modes.

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

2Ease of operation

If the operating unit is detached for remote operation, then user convenience is improved, but safety control capability deteriorates

Engineering Contradiction:
Improveuser convenienceVSAvoidsafety control capability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system dynamically adjusts its operational characteristics based on the attachment state. When detached, the operating unit provides remote control capability for convenience. The dynamic nature of the attachment mechanism allows users to switch between attached (full safety control) and detached (remote convenience) modes as needed.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If the operating unit provides full functionality when detached, then user autonomy is improved, but safety risks increase

Engineering Contradiction:
Improveuser autonomyVSAvoidsafety risks
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The operating unit has different functional capabilities depending on its attachment state. When attached, it provides full functionality including all safety-critical controls. When detached, it provides a reduced set of functions that maintain user autonomy for non-critical operations while eliminating safety risks associated with remote control of dangerous functions.

Inventive Principle:
Principle #3Local quality

AI summary

An electrical kitchen appliance for preparing food has an operator control unit for entering control instructions for control of the electrical kitchen appliance by a user. The operator control unit can be removably attached to the electrical kitchen appliance and, in the process, can be operated in a first operating mode and in a second operating mode, wherein the operator control unit for entering control instructions for control of the electrical kitchen appliance by the user is attached to the electrical kitchen appliance in the first operating mode and is removed from the electrical kitchen appliance in the second operating mode. An electrical kitchen appliance of this kind which has an operator control unit which can be individually operated is provided in this way.
