This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,114.

Summary of the Inventive Concept

The present disclosure relates to an innovative hand-held electric barbecue device that integrates with distinct technologies such as AI, IoT, blockchain, and new materials to create a more powerful, automated, and connected barbecue cooking system.

Background and Problem Solved

Traditional hand-held electric barbecue devices have limitations in terms of cooking control, safety, and user experience. The original patent addressed some of these limitations, but the new inventive concept takes a significant leap forward by incorporating advanced technologies to provide real-time temperature control, IoT-enabled monitoring, blockchain-based food safety tracking, and AI-powered cooking assistance.

Detailed Description of the Inventive Concept

The new system comprises a hand-held electric barbecue device, a temperature sensor, a microcontroller, and a wireless communication module. The microcontroller adjusts cooking parameters based on real-time temperature data, ensuring optimal cooking results. The IoT-enabled monitoring feature transmits cooking data to a remote server for analysis and feedback. The blockchain-based food safety tracking module provides a secure and transparent record of cooking history and safety certifications. The AI-powered cooking algorithm offers personalized cooking recommendations and guidance through a user-friendly interface. The modular design allows for easy replacement and upgrade of the power module and cooking fork.

Novelty and Inventive Step

The new claims introduce a synergistic combination of distinct technologies, creating a novel and non-obvious system that significantly improves the cooking experience, safety, and user interface. The integration of AI, IoT, blockchain, and new materials with the hand-held electric barbecue device provides a unique and innovative solution that was not possible with the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include varying the type of sensor used, incorporating additional IoT-enabled features, or utilizing different blockchain platforms. The modular design could also be adapted for use with other types of cooking devices or appliances.

Potential Commercial Applications and Market

The intelligent hand-held electric barbecue device has significant commercial potential in the outdoor recreation, camping, and backyard cooking markets. The integration of advanced technologies could appeal to tech-savvy consumers, while the improved cooking experience and safety features could attract a broader audience. Potential industries for commercial application include consumer electronics, outdoor recreation, and food service.
