Heat-cooking system and method for testing a heat-cooking appliance of a heat-cooking system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heat-cooking systems face difficulties in identifying the source of communication faults between a heat-cooking appliance and a portable terminal when using a wireless relay, making it challenging to determine whether the issue lies with the wireless relay, the heat-cooking appliance, or the portable terminal.
Innovation Solution
The system enables direct communication between the heat-cooking appliance and the portable terminal through an access point mode, allowing for the execution of a test mode that helps isolate faults by performing internal communication and displaying the operating state, thereby facilitating the identification of problems in the wireless communication environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If indirect communication via wireless relay is used between heat-cooking appliance and portable terminal, then communication convenience is improved, but fault identification difficulty increases
Solution Approach 1:
The system segments the communication path into two modes: indirect communication via wireless relay for normal operation, and direct communication for testing. This segmentation allows the test mode to bypass the wireless relay and directly test the heat-cooking appliance's communication function, isolating the fault to either the appliance itself or the relay infrastructure.
Solution Approach 2:
The patent introduces a dual communication path where direct communication serves as an intermediary test mechanism. When indirect communication fails, the system switches to direct communication as a mediator to determine whether the fault lies with the heat-cooking appliance or the wireless relay, enabling fault isolation without requiring physical inspection of the relay.
2Difficulty of detecting and measuring
If direct communication mode is added for testing, then system complexity increases, but fault detection capability improves
Solution Approach 1:
The heat-cooking appliance is equipped with multi-functional communication capability, supporting both indirect communication (normal operation) and direct communication (testing). This universal communication design allows a single device to perform multiple functions: routine wireless communication via relay and self-diagnostics via direct connection, eliminating the need for separate testing equipment.
Solution Approach 2:
The system implements self-service diagnostics by enabling the heat-cooking appliance to autonomously test its own communication function. The appliance can switch to direct communication mode, execute communication tests, and identify faults without external intervention or complex testing equipment, reducing overall system complexity while maintaining high detection capability.
