Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing home appliances face inefficiencies in updating load control and operation mode data, as load control data, safety control data, firmware data, and application data are mixed in the same memory, making it difficult to perform efficient updates or upgrades.
Innovation Solution
A home appliance system with separate circuits for load control and operation mode control, utilizing a first circuit for load control and safety control, and a second circuit for operation mode control based on an operating system, allowing for efficient firmware and software updates through independent processing and communication between processors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If load control data, safety control data, firmware data, and application data are mixed in the same memory, then device complexity is reduced, but update efficiency deteriorates
Solution Approach 1:
The patent divides the memory system into separate storage areas: a first memory for storing firmware data and a second memory for storing application data. This segmentation allows independent updates of firmware and application data, resolving the contradiction by enabling efficient updates without requiring complex unified memory management.
Solution Approach 2:
The patent extracts application data from the firmware storage area and places it in a separate second memory. This extraction allows the application data to be updated independently and more frequently without affecting the firmware, thus improving update efficiency while maintaining a relatively simple overall device structure.
2Device complexity
If firmware and operation mode control are integrated in one processor, then device complexity is reduced, but adaptability deteriorates
Solution Approach 1:
The patent segments the control system into a first processor for firmware-based load control and a second processor for operation mode control. This segmentation enables independent upgrading of operation modes through the second processor without affecting the core firmware functionality, thus improving adaptability while maintaining manageable device complexity.
Solution Approach 2:
The patent extracts operation mode control functions from the firmware processor and implements them in a separate second processor. This extraction allows flexible updates of operation modes and applications without requiring firmware changes, enhancing adaptability while keeping the overall processor architecture relatively simple.
3Productivity
If separate circuits are used for load control and operation mode control, then update efficiency is improved, but device complexity increases
Solution Approach 1:
The patent implements segmentation by creating separate first and second circuits with distinct processors and memory areas. The first circuit handles firmware-based load control while the second circuit manages operation mode control. This segmentation enables parallel and independent updates, significantly improving update efficiency despite the increased circuit architecture complexity.
