Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional manual control of household devices is inconvenient for physically disabled, elderly, and young children, and existing smart systems require complex setups that are difficult to manage, especially in a kitchen environment where multiple devices need separate controls.
Innovation Solution
A control system with a master module in wireless communication with slave modules, utilizing both Bluetooth Low Energy (BLE) and Wi-Fi for integration of smart devices, including a cloud-based network for centralized control and monitoring, allowing seamless interaction and management of various kitchen appliances through a single interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If full integration of smart devices is implemented, then convenience and usability are improved, but device complexity and difficulty of setup increase
Solution Approach 1:
The patent introduces a microcontroller unit (MCU) as an intermediary device that acts as a bridge between multiple smart devices and the user's smartphone. The MCU receives commands from the smartphone via Bluetooth and distributes them to connected devices, while also aggregating status information from devices to report back. This intermediary approach allows full device integration without requiring the smartphone to directly manage each device's complex protocols and settings.
Solution Approach 2:
The patent combines multiple communication protocols (Bluetooth, Wi-Fi) and device control functions into a single integrated system centered around the MCU. Instead of requiring separate control mechanisms for each smart device, the system merges all device interactions through the unified MCU interface, simplifying the user experience while maintaining comprehensive device management capabilities.
2Device complexity
If multiple separate controls are used for different devices, then device complexity is reduced, but ease of operation deteriorates
Solution Approach 1:
The MCU is designed with universal functionality to communicate with and control multiple different types of smart devices (lights, plugs, sensors, etc.) through a single interface. The system provides multi-functional control capabilities including remote switching, dimming, timing, and status monitoring, all accessible through one smartphone application, eliminating the need for separate controls for each device type.
Solution Approach 2:
The MCU serves as a universal mediator that translates user commands into device-specific protocols and aggregates device status information into a unified format for the smartphone application. This allows users to manage multiple diverse devices through a single consistent interface without dealing with individual device complexities.
3Adaptability or versatility
If cloud-based network is implemented, then remote control capability is improved, but loss of information and security risks increase
Solution Approach 1:
The patent implements a hybrid communication approach where Bluetooth Low Energy (BLE) is used for local device control without cloud connectivity, providing basic remote control capabilities within range. Wi-Fi and cloud-based services are offered as optional enhancements for extended remote access, allowing users to benefit from cloud capabilities only when needed while maintaining secure local operation as the default, thus minimizing security risks while preserving versatility.
