Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing home appliance connection methods face challenges in accurately and efficiently searching for and connecting to wireless networks, particularly due to limitations in user interface availability and power consumption, leading to inaccurate network identification and prolonged search durations.
Innovation Solution
A home appliance connection device that operates in station and access point modes, periodically searches for wireless networks, filters out irrelevant information, and transmits accurate access point data to the terminal device, minimizing user intervention and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the terminal device performs wireless network searching, then the connection process can be initiated, but the search accuracy is insufficient and the search duration is prolonged
Solution Approach 1:
Instead of having the terminal device search for the wireless network (traditional approach), the home appliance connection device performs the search and provides results to the terminal device. This inversion of the search role resolves the contradiction by enabling accurate searches at the home appliance location while reducing terminal device search duration.
Solution Approach 2:
The home appliance connection device acts as an intermediary between the terminal device and the wireless network. It performs the actual network search, filters relevant information, and transmits results to the terminal device, thereby improving search accuracy and reducing the time the terminal device needs to spend searching.
2Reliability
If the home appliance performs wireless network searching and connection maintenance, then network connectivity is achieved, but power consumption increases significantly
Solution Approach 1:
The home appliance connection device performs preliminary wireless network searching and stores the results in advance. When the terminal device needs to connect, the pre-searched network information is provided, eliminating the need for continuous searching and reducing power consumption while maintaining reliable connectivity.
Solution Approach 2:
Instead of continuously searching for wireless networks, the home appliance connection device performs periodic searches at intervals. This approach maintains network connectivity reliability while significantly reducing the overall power consumption compared to continuous searching operations.
3Device complexity
If the home appliance has a limited user interface, then the appliance design is simplified, but the user cannot perform wireless network searching and connection setup
Solution Approach 1:
The home appliance connection device autonomously performs wireless network searching, filtering, and connection setup without requiring user intervention through a user interface. The device serves itself by automatically establishing network connections, thereby maintaining simple design while ensuring operational capability.
Solution Approach 2:
The home appliance connection device serves as an intermediary that handles all complex wireless network operations. The terminal device user interacts only with the terminal's interface, while the connection device manages the actual network search and connection process, effectively decoupling the need for a user interface from the connection setup capability.
