Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current household appliances lack the ability for users to create and run custom sequence programs without compromising security or operational safety, limiting their adaptability and functionality.
Innovation Solution
A method that allows users to create and execute sequence programs on household appliances by checking predetermined device conditions, enabling user-controlled scheduling while preventing unsafe operations through static and dynamic testing, and allowing parameter adjustments to ensure compliance with device specifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users are allowed to create and execute custom sequence programs on household appliances, then adaptability and functionality are improved, but operational safety and security may be compromised
Solution Approach 1:
The patent applies preliminary action by checking the user-created sequence program against predetermined appliance conditions before execution. The control device validates the program in advance to ensure it meets safety requirements, preventing potentially harmful operations from being executed while still allowing user customization.
Solution Approach 2:
The patent introduces an intermediary validation mechanism between the user program creation and appliance execution. The control device acts as a mediator that intercepts the user program, checks it against safety conditions, and only permits execution if validation succeeds, thus protecting the appliance while maintaining user adaptability.
2Ease of operation
If users can create custom sequence programs externally, then ease of operation is improved, but device complexity increases due to validation requirements
Solution Approach 1:
The patent extracts the program creation functionality from the appliance itself, allowing users to create sequence programs on external devices. This removes the need for complex programming interfaces on the appliance, maintaining ease of operation while reducing the appliance's operational complexity.
Solution Approach 2:
The validation of user programs is performed as a preliminary check before execution. The control device validates the program structure and parameters against predetermined conditions in advance, which adds a layer of complexity but maintains ease of operation by providing clear feedback to users about program validity.
