Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current integrated cookers have a low integration level of their control systems due to the separate placement of heating control devices and driver devices, leading to increased assembly costs and complexity, as well as the need for specific communication circuits for different heating modes, limiting flexibility and compatibility.
Innovation Solution
The integration of heating control devices and driver devices within the cooker body, along with a universal communication circuit that uses flag bits to identify and adapt to different devices, allowing for flexible assembly and replacement without requiring a new primary control board, thus enhancing integration and compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If heating control device and driver device are disposed separately (heating control inside panel, driver device near functional device), then each device can be independently controlled, but the integration level of control system decreases and assembly complexity increases
Solution Approach 1:
The patent merges the heating control device and driver device into a single integrated control device disposed within the cooker body. This integration consolidates multiple control functions into one unit, improving the integration level of the control system while reducing assembly complexity and the number of wiring harnesses required.
Solution Approach 2:
The integrated control device is designed with multi-functional capabilities, incorporating both heating control and driver device functions within a single unit. This universal design allows the control device to handle multiple tasks (heating control, fan control, steam device control) while maintaining adaptability and reducing the need for separate specialized components.
2Reliability
If separate communication circuits are designed for different heating modes, then specific heating functions can be precisely controlled, but manufacturing cost increases and flexibility decreases
Solution Approach 1:
The patent implements a universal communication circuit within the integrated control device that can adapt to different heating modes (electromagnetic heating, infrared heating, conduction heating) through software configuration rather than hardware variation. This approach maintains precise control over specific heating functions while significantly reducing manufacturing costs and improving flexibility by eliminating the need for mode-specific communication circuits.
Solution Approach 2:
The communication circuit uses parameter changes (flag bits) to differentiate and control various heating modes. By changing software parameters and control signals rather than hardware architecture, the system achieves precise control over different heating functions while maintaining a single, cost-effective communication circuit design that enhances manufacturing ease and flexibility.
3Measurement precision
If specific communication circuits are required for different heating modes, then heating control precision is improved, but device complexity and assembly cost increase
Solution Approach 1:
The integrated control device employs a universal communication circuit that can identify and control multiple heating modes through a single interface. The circuit uses flag bits and software-based mode identification to achieve precise heating mode detection without requiring separate communication circuits for each heating type, thereby reducing device complexity and assembly cost while maintaining high measurement precision.
4Device complexity
If heating control device and driver device are integrated inside cooker body, then integration level improves and wiring harnesses decrease, but heat dissipation becomes more challenging
Solution Approach 1:
The patent segments the integrated control device into distinct functional modules (heating control module, driver module, communication module) that can be spatially distributed within the cooker body. This segmentation allows strategic placement of heat-generating components away from heat-sensitive areas while maintaining integration benefits, thus improving heat dissipation efficiency without sacrificing control system integration.
