AR Food Processor Interface for Cleanable Display-Free Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional food processors require users to manually check integrated displays, which can be cumbersome and lead to a less intuitive operation experience, and may collect dirt, making cleaning difficult.
Innovation Solution
A portable image generating device, such as eye-worn goggles, projects information about operating and preparation parameters directly into the user's field of vision using augmented reality, eliminating the need for integrated displays and allowing for virtual information to be displayed near or on the food processor components, with touch sensors enabling control inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If integrated displays are used on the food processor housing, then users can see operating parameters, but the housing surface becomes prone to dirt accumulation and is harder to clean
Solution Approach 1:
The patent uses a portable image generating device to project visual information about operating parameters onto the housing surface, creating a virtual copy of the display functionality without physical display components. This allows users to see operating parameters while maintaining a smooth, cleanable housing surface without integrated displays or gaps where dirt could accumulate
2Ease of operation
If manual checking of integrated displays is required, then control functions are accessible, but user interaction becomes cumbersome and less intuitive
Solution Approach 1:
The patent introduces a portable image generating device as an intermediary between the food processor's control system and the user's vision. This device projects operating parameters and control interfaces directly into the user's field of view, eliminating the need for the user to physically approach and manually check integrated displays, thereby making interaction more intuitive and time-efficient
3Ease of operation
If physical displays and control elements are integrated into the housing, then users can access information and controls, but the device complexity and number of components increase
Solution Approach 1:
The patent extracts the display and control interface functions from the food processor housing itself and relocates them to a separate portable image generating device. This extraction eliminates the need for integrated displays, buttons, and control elements in the housing, thereby reducing device complexity and component count while maintaining full user interface functionality through the portable device
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 solution enhances user interaction by providing intuitive access to information and control functions without the need for physical displays on the food processor, reducing dirt accumulation and simplifying cleaning while maintaining a sleek, robust design.
Implementation Method 1
the information is provided with the aid of a portable image generating device designed separately from the food processor, in particular one in front of one eye of the user, with the information being projected into the user's field of vision

AI summary
The invention relates to a method for operating an electric motor-driven food processor (1) for preparing food, the food being prepared in one or more successive preparation steps, with a user of the food processor (1) setting an operating parameter of the food processor (1) and/or receives information (2) relating to a preparation parameter of the food to be prepared from the food processor (1) and/or transmits it to the food processor (1). In order to make the operation of the food processor (1) particularly convenient for the user, it is proposed that the information (2) be transmitted with the aid of a portable image generating device (3) designed separately from the food processor (1), in particular a spectacle-like construction worn in front of one eye , is projected into the users field of vision when the user looks at the food processor (1) in a defined angular range, with the information (2) being superimposed on the field of vision. In addition, an electrically driven food processor (1) and a system made up of such a food processor (1) and a portable imaging device (3) are also proposed.
