Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wiring systems are used to connect PV panels and batteries, then electrical connectivity is achieved, but safety risks increase and potential-induced degradation occurs
Solution Approach 1:
The patent extracts and eliminates the traditional wiring system from the PV array configuration. By using integrated conductive connectors that are built into the frame structure, the separate wiring components are removed, thereby reducing safety risks associated with external wiring while maintaining electrical connectivity.
Solution Approach 2:
The patent merges the structural frame with the electrical connection function by integrating conductive connectors directly into the frame. This combination eliminates the need for separate wiring systems, reducing both complexity and safety risks while maintaining reliable electrical connections between PV panels and batteries.
2Adaptability or versatility
If multiple wiring connections are added to increase PV system connectivity, then system expandability is improved, but fire hazards and wiring breakdown risks increase
Solution Approach 1:
The patent segments the PV system into modular units, each with integrated conductive connectors. This segmentation allows systems to be expanded by simply adding modular units with built-in connection capabilities, eliminating the need to add additional wiring connections and thereby reducing fire hazards associated with increased wiring density.
3Reliability
If complex wiring sequences are used to connect PV array components, then electrical connectivity is achieved, but installation time and complexity increase
Solution Approach 1:
The conductive connectors are pre-integrated into the frame structure during manufacturing. This preliminary action eliminates the need for complex wiring sequences during installation, as connectors are already in place and simply need to be aligned and connected, significantly reducing installation time while maintaining reliable electrical connectivity.
4Strength
If traditional PV array systems are configured with separate wiring and structural components, then structural integrity is maintained, but system reliability decreases due to wiring failures
Solution Approach 1:
The patent merges the structural frame with the electrical connection function by integrating conductive connectors directly into the frame. This integration ensures that the structural components that provide integrity also provide reliable electrical connections, eliminating the separate wiring system that is prone to failures and thereby improving overall system reliability.
