Food Processor Gesture Control for Hands-Free Hygienic Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional food processors require manual operation and contact with controls for setting parameters like speed, temperature, and duration, which can be cumbersome and unsanitary, especially for complex tasks.
Innovation Solution
Integration of a camera and gesture recognition software that allows users to control the food processor using gestures, eliminating the need for physical contact and enabling hands-free operation, with optional speech control and face recognition for enhanced security and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation with physical contact controls is used, then the device structure remains simple, but the ease of operation deteriorates and hygiene is compromised
Solution Approach 1:
The patent replaces mechanical contact-based control (buttons, switches) with a gesture recognition system using a camera and image processing software. Users control the food processor by making hand gestures in the camera's field of view, eliminating the need for physical contact with controls. This substitution of mechanical interaction with optical recognition resolves the contradiction by improving ease of operation and hygiene while accepting increased device complexity through the addition of camera and software components.
2Ease of operation
If gesture recognition system is integrated, then hands-free operation is enabled improving hygiene, but device complexity increases
Solution Approach 1:
The patent introduces a camera as an intermediary between the user and the control system. Instead of direct mechanical contact or voice recognition, the camera captures hand gestures and translates them into control commands through image processing software. This intermediary approach enables hands-free operation for improved hygiene while managing complexity through a dedicated sensing and processing subsystem rather than integrating recognition capabilities into the core control logic.
3Reliability
If multiple recognition modes (gesture, face, speech) are added for security, then reliability improves, but device complexity and cost increase
Solution Approach 1:
The patent implements multiple recognition modes (gesture recognition, face recognition, and speech recognition) within a unified control system. The camera serves multiple functions: capturing images for gesture recognition, capturing facial images for face recognition, and potentially serving as a flash for speech recognition activation. This multi-functionality approach improves reliability and security through diverse authentication methods while managing complexity by having a single sensor component perform multiple recognition tasks rather than requiring separate dedicated sensors for each mode.
Data Source
AI summary
An electrically operated food processor with a mixing bowl and a mixer in the mixing bowl is provided with a camera, in particular an electronic camera, which is potentially directed towards the user of the food processor, and with stored gesture recognition software, as well as a gesture data bank, it being possible to use gesture recognition to cause the food processor to carry out a routine task.
