Solution Overview
Problem
Existing wireless networks for electronic devices, such as solar inverters, face challenges in maintaining efficient radio coverage and network management due to unpredictable device positioning and environmental factors, requiring a large number of access points and complex infrastructure, which is difficult to set up and maintain.
Innovation Solution
Implementing a wireless network where each electronic device has a dual-function wireless communication unit capable of acting as both a station and an access point, allowing for dynamic adaptation and extension of the network by selecting available devices to act as bridges or access points, enabling efficient data communication and network expansion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large number of access points are deployed to maintain radio coverage over widely distributed electronic devices, then network coverage and reliability are improved, but device complexity and installation difficulty increase
Solution Approach 1:
Each electronic device is equipped with a wireless communication unit that can function both as a station (client) and as an access point (server). This multi-functionality allows devices to dynamically adapt their role based on network needs, eliminating the requirement for dedicated access points and reducing overall network complexity while maintaining comprehensive coverage.
Solution Approach 2:
The wireless communication units automatically detect their operational context and switch between station and access point modes without external intervention. When a device detects that it needs to extend network coverage, it autonomously activates its access point function, enabling the network to self-organize and adapt to changing conditions without requiring manual configuration or intervention.
2Reliability
If access points are strategically positioned to optimize signal strength, then network performance is improved, but installation time and technical skill requirements increase
Solution Approach 1:
The network topology is dynamic rather than static. Each wireless communication unit can switch between station and access point modes based on real-time conditions such as signal strength, device distribution, and network coverage requirements. This dynamic adaptation eliminates the need for careful pre-planning and strategic positioning of access points, as the network automatically reconfigures itself to optimize performance.
3Reliability
If the network layout is modified to adapt to changes in device arrangement or environmental factors, then network reliability is improved, but maintenance complexity and time requirements increase
Solution Approach 1:
The network automatically adapts to changes in device arrangement and environmental conditions through dynamic mode switching. When devices are added, removed, or relocated, the wireless communication units automatically adjust their roles (station or access point) to maintain optimal network connectivity and coverage, eliminating the need for manual reconfiguration or maintenance interventions.
Solution Approach 2:
The wireless communication units continuously monitor network conditions, signal strength, and device connectivity status. Based on this feedback, devices automatically adjust their operational mode to maintain network reliability. This closed-loop control ensures the network remains adaptive and self-healing without requiring manual maintenance or reconfiguration.
4Area of stationary object
If additional access points are installed to extend network range to remote devices, then network coverage is improved, but cost and infrastructure requirements increase
Solution Approach 1:
Every electronic device in the network possesses dual functionality as both station and access point. This universality allows any device to serve as a coverage extension point, eliminating the need for additional dedicated access points. The network coverage area is extended by leveraging the existing devices' wireless capabilities rather than adding new infrastructure components.
