Kitchen Appliance Accessory with Position Sensor for Safe Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing kitchen appliances lack a mechanism to ensure proper positioning of accessories, leading to potential damage and unsafe operation, as current RFID-based identification systems do not verify correct positioning before enabling appliance functions.
Innovation Solution
Incorporating a transponder arrangement with an accessory position sensor in kitchen appliance accessories, which detects and transmits position parameters to a reading arrangement, ensuring correct positioning before enabling appliance functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If RFID-based identification is used to identify accessories, then accessory identification is enabled, but proper positioning verification is not ensured
Solution Approach 1:
The patent combines RFID identification functionality with position sensor functionality into a single integrated transponder arrangement. The transponder includes both the identification module and accessory position sensors that detect positioning parameters, allowing simultaneous identification and positioning verification through a single component rather than separate systems.
Solution Approach 2:
The transponder arrangement acts as an intermediary between the accessory and the reading arrangement. It receives the interrogation signal from the reading arrangement, processes both identification data and position sensor data, and transmits both types of information back to the control unit, enabling centralized verification of both identity and positioning.
2Ease of operation
If accessory identification is performed without positioning verification, then operation is simplified, but appliance damage risk increases
Solution Approach 1:
The system performs preliminary verification of both accessory identification and positioning parameters before enabling appliance operation. The control unit receives and evaluates position parameters from the transponder before authorizing the appliance to execute functions, ensuring that proper positioning is confirmed in advance to prevent damage.
Solution Approach 2:
The transponder provides feedback to the control unit regarding both accessory identification and positioning status. The control unit uses this feedback to determine whether the accessory is properly positioned and authenticated before enabling appliance functions, creating a closed-loop verification system that prevents operation with improperly positioned accessories.
