Recipe Parameter Validation in Multi-Function Cooking Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-function cooking apparatuses face challenges in ensuring proper operation when executing recipe programs, as they may contain unintentional or malicious technical parameter settings that can lead to malfunction or safety hazards, such as overheating, spilling hot ingredients, or sabotage, due to typing errors, corruption, or malicious intent.
Innovation Solution
The cooking apparatus incorporates a parameter check component that applies compatible technical parameter setting rules to prevent loading and execution of recipe programs with incompatible settings, using a stepwise or blockwise reading approach to ensure compliance with stored rules, thereby preventing harmful or malicious code from being executed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the cooking apparatus executes recipe programs with technical parameter settings, then automated cooking functionality is improved, but the risk of malfunction and safety hazards increases due to incompatible or malicious settings
Solution Approach 1:
The patent implements a parameter validation mechanism that checks technical parameter settings against predefined compatibility rules before executing the recipe program. This preliminary validation prevents incompatible or malicious parameters from causing malfunctions or safety hazards, thereby maintaining automation while ensuring reliability.
2Adaptability or versatility
If the cooking apparatus accepts external recipe programs via Wi-Fi interface, then recipe variety and user convenience are improved, but the risk of malicious manipulation increases
Solution Approach 1:
The patent introduces an intermediary validation layer between the Wi-Fi interface and the execution engine. This intermediary checks incoming recipe programs against compatibility rules, filtering out malicious or incompatible parameters while allowing legitimate diverse recipes to be executed, thus maintaining versatility while blocking harmful inputs.
3Reliability
If the cooking apparatus performs parameter validation before execution, then operation safety is improved, but the complexity of the control system increases
Solution Approach 1:
The patent segments the control system into distinct modules: a parameter validation module that checks compatibility rules and an execution module that runs validated recipes. This segmentation isolates the complexity of validation logic from the execution path, making the overall system more manageable while maintaining safety through systematic parameter checking.
