Cooktop Utensil Handle with Sensor-Based Grip and Input Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooktop utensils lack effective prevention of improper handling, which can lead to safety issues and unintended control actions, especially when distinguishing between gripping and inputting user commands.
Innovation Solution
The cooktop utensil features a handle with a gripping portion and an input portion, equipped with sensors that detect user approach or contact, allowing for differentiation between gripping for movement and inputting commands, thereby preventing unintentional control actions and enhancing safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the handle is used for both gripping and input operations, then the device is easier to operate, but improper handling and unintended control actions occur
Solution Approach 1:
The handle is divided into two distinct portions: a gripping portion for manual handling and an input portion for control operations. This spatial segmentation prevents accidental input actions when gripping the handle, while maintaining overall ease of operation.
Solution Approach 2:
A sensor is introduced as an intermediary element in the gripping portion to detect user approach or contact. This sensor mediates between the user's physical interaction and the control system, enabling automatic detection of gripping intentions and preventing unintended control actions.
2Reliability
If sensors are added to detect user intentions, then safety and improper handling prevention are improved, but device complexity increases
Solution Approach 1:
The sensor system operates autonomously to detect user intentions and trigger appropriate responses without requiring additional complex control logic. The sensor in the gripping portion self-activates when a user approaches or contacts it, automatically preventing unintended input actions.
Solution Approach 2:
The sensor functionality is integrated into the existing handle structure, merging the detection capability with the mechanical component. This reduces overall device complexity by combining functions rather than adding separate systems.

AI summary
A placeable cooktop utensil includes: a handle for handling the placeable utensil; a controller; a transmitter unit for transmitting signals from the placeable utensil to the cooktop; and at least one input unit having at least one input area integrated in the handle for a user of the placeable utensil to input a user command, the transmitter unit and the at least one input unit being connected in signal communication with the controller, and the cooktop being controllable by the user command. The handle has a gripping portion for gripping and manually moving the placeable utensil and at least one input portion. The at least one input area is in the at least one input portion. At least one sensor for detecting the handle being approached and/or contacted by the user, is in the gripping portion.
